Professional heavy-truck transmission diagnostics, maintenance, and repair
Professional Heavy-Truck Transmission Repair
A truck’s transmission works under extreme load every mile you drive, delivering engine torque directly to the wheels. That’s why even the most durable manual or automatic gearboxes eventually start to fail. Typical warning signs include grinding or whining noises, delayed or difficult shifting, gears dropping out under load, jerky acceleration, and visible transmission fluid leaks. Ignoring these symptoms quickly leads to major internal damage and extremely expensive repairs.
If your transmission makes unusual noises, shifts harder than usual, or you’ve noticed oil spots under the truck – schedule an urgent diagnostic. Early inspection can save the transmission and keep your rig on the road.
Quick truck windshield and side glass replacement
The windshield is one of the main safety components of any truck. Cracks, chips, or shattered glass limit your visibility and can trigger fines during police or inspection checks. Severe damage requires immediate replacement – driving with compromised glass puts you and your load at risk. Side window damage is no different: a broken window exposes the cab, affects mirror visibility, and creates unsafe blind spots. Rock hits, accidents, and temperature shocks are the most common causes. If your truck has a crack, a major chip, or broken glass, act fast – the damage will spread, and the window can collapse completely at the worst possible moment.
Advanced clutch diagnostics, repair, and full restoration for all truck brands
Comprehensive Truck Clutch Service – Diagnostics, Repair & Replacement
A truck’s clutch endures extreme torque and heavy loads, making it one of the most vulnerable parts of the drivetrain. Slipping under load, delayed or stiff shifting, strange rattling, or a burnt smell in the cab are all signs the clutch is on its way out. A pedal that suddenly feels too loose or too stiff is another red flag. Driving with these symptoms can end in a complete clutch failure and leave your truck stranded on the highway. Getting the clutch inspected immediately prevents costly gearbox damage and avoids extended downtime.
LKWHelp24 offers rapid, full-service clutch repair anywhere in Germany. We send certified mechanics 24/7 or arrange professional towing straight to the nearest workshop equipped for clutch replacement. Our team specializes in high-complexity jobs – including gearbox removal – and performs them quickly and to factory standards. Through our nationwide network of partner service centers, we always select the closest shop with the right clutch kits in stock. We service all major European truck brands (MAN, Volvo, Scania, DAF, Mercedes-Benz, Iveco, etc.), ensuring precise repair tailored to each manufacturer’s system. Our mission is speed and reliability: we get your truck back on the road with a new clutch in minimum time, operating round-the-clock without weekends or holidays.
A/C diagnostics, service, and recharge for heavy trucks
LKWHelp24 delivers fast and reliable truck A/C service across Germany – available 24/7. We dispatch mobile technicians to your breakdown location or direct you to a trusted partner workshop nearby. Our service begins with full diagnostics: refrigerant pressure testing, leak detection, compressor and fan performance checks. If a leak is found, we repair the fault, replace damaged hoses if needed, and recharge the system with certified refrigerant. In cases of compressor failure, we install high-quality replacements compatible with MAN, DAF, Scania, Volvo, Mercedes, Iveco, and all major truck brands. We use premium components only: compressor oil, certified refrigerant, and new dryer filters to ensure reliable cooling performance.
Most A/C systems are restored within 1-2 hours, delivering cold airflow again. With LKWHelp24, your truck stays cool even during peak summer temperatures – our emergency crews work around the clock to keep drivers comfortable and safe on the road.
Tarp repair service for semi-trailers
Advanced truck electrical diagnostics and repair of wiring and circuits
Headlight issues, dead marker lights, wiring faults, starter trouble, or a failing alternator always hit when you least expect it. Modern rigs are packed with control modules and miles of cables – when the electrics act up, you need a real truck electrician.
We run a 24/7 mobile electrical service all over Germany. Dealer-grade diagnostics, pro tools, and fast troubleshooting – from a popped fuse to a broken harness. We fix wiring on the spot, swap bad parts, rebuild starters and alternators, and get you rolling again with minimum downtime.
Turbo repair and swap service for heavy trucks
The turbocharger is one of the key components responsible for diesel engine performance, which means any failure immediately affects the truck’s power and drivability. Typical symptoms of turbocharger issues include loss of engine power, slow acceleration, heavy black or blue exhaust smoke, increased oil consumption, and a noticeable whistle or howl during turbo spool. Continuing to drive with a damaged turbocharger can lead to rapid system failure – overheating or imbalance may cause total turbo destruction and severe engine damage. For this reason, any early warning signs – low power under load, excessive smoke, or boost-related fault codes – require immediate professional attention.
LKWHelp24 delivers fast, reliable turbocharger repair and replacement for all major truck brands across Germany. With a nationwide network of certified partner workshops and fully equipped mobile service units, we ensure minimal downtime and maximum efficiency. Our technicians begin with a full diagnostic inspection: turbo shaft play, hose integrity, intercooler condition, and ECU fault codes. In many cases, a targeted repair is sufficient – gasket replacement, VGT cleaning, actuator repair. If the turbocharger is beyond repair, we arrange installation of a new unit. Many turbo replacements can be completed on-site using our mobile workshop, equipped with all necessary tools and pressure-testing equipment. This eliminates the need for towing and significantly shortens repair time. If on-site work is not feasible due to additional engine damage, we provide fast transport to the nearest specialized facility. Our team has extensive experience with MAN, Mercedes-Benz, Volvo, Scania, DAF, Iveco and other brands, including complex two-stage turbo setups and related electronic systems. Operating 24/7, LKWHelp24 ensures your turbocharger is repaired or replaced anytime – day or night – restoring full engine performance and keeping your schedule intact.
Professional brake diagnostics, pad/rotor replacement, and caliper repair
Brakes are the most important safety system on any heavy truck. When pads wear down and rotors lose thickness, the braking power drops fast: stopping distance increases, the truck vibrates under braking, the system overheats, and in a critical moment the brakes can fail completely. Squeaks, grinding, pedal vibration, steering shake, the truck drifting to one side, a soft pedal, or ABS triggering too often – all these signs mean your braking system needs immediate attention. Ignoring them puts the driver, the cargo, and everyone on the highway at risk.
LKWHelp24 delivers fast, professional brake service for all heavy-duty trucks across Germany – on the road, at the yard, or at one of our partner shops. We dispatch the nearest mobile mechanic or guide you to a certified workshop that can start repairs immediately. Our techs arrive with the most common brake pads and rotors for MAN, Mercedes-Benz, DAF, Volvo, Scania, Iveco and other major brands. In most cases, we replace pads on-site within minutes, keeping your downtime to a minimum.
Our service includes:
• installation of new brake pads
• rotor replacement if required
• caliper cleaning and lubrication
• brake system bleeding
• inspection of brake chambers and ABS/EBS sensors
If the damage is severe – seized caliper, pneumatic leaks, or system failure – we arrange towing to the nearest partner facility equipped for heavy repairs. With over 1,000 verified partners across Germany, we guarantee quick access to the right parts and specialists.
LKWHelp24 keeps your truck stopping strong and safe – 24/7, day or night, weekends or holidays. When brakes fail, every minute counts. We get you back on the road fast.
SCR/AdBlue repair for heavy trucks
Euro 5/6 diesel trucks rely on an SCR system with AdBlue to meet strict emission standards. By injecting urea into the exhaust stream, the system significantly reduces harmful emissions. A malfunction in the AdBlue/SCR system can cause immediate operational issues: reduced engine power, limp mode, increased fuel consumption, and in some cases complete engine lockout to prevent emission violations. Warning lights on the dashboard, poor acceleration, ammonia odor, or rising fuel usage are key indicators. Common causes include frozen or crystallized AdBlue, pump failure, clogged dosing injectors, and faulty NOx or temperature sensors. Urea crystallization can block lines, while improper dosing leads to ineffective catalytic performance. Continuing to drive with SCR faults risks vehicle shutdown and fines under German emission regulations.
LKWHelp24 provides nationwide AdBlue system diagnostics and repair for all major truck brands. With deep expertise in SCR technology, our technicians service AdBlue pumps, dosing units, injectors, SCR control modules, pressure sensors, and quality monitoring components. A complete diagnostic scan is performed first: ECU and SCR fault readings, pressure and flow checks, and inspection of hoses for crystallization. Based on the results, we resolve the problem quickly – from NOx sensor replacement and injector cleaning to full system flushing. If the AdBlue pump or dosing module fails, we supply and install a new unit without delay. Our mobile service vehicles are equipped to perform SCR repairs directly on the roadside, dramatically reducing downtime. After repairs, we conduct a test cycle and reset fault codes to confirm full engine performance. We support MAN, Volvo, Scania, DAF, Mercedes-Benz, Iveco, and all other major brands. Available 24/7, LKWHelp24 ensures full emission compliance and keeps your truck on schedule.
Alternator diagnostics, repair, and rebuild for trucks
The alternator is the core of your truck’s electrical system. It powers every critical component, keeps your battery charged, and ensures the rig stays running. When the alternator starts to fail, the voltage drops instantly: lights dim, electronics malfunction, and the battery warning light appears. On modern heavy-duty trucks, the electrical system also controls the air system, fuel injection, and major safety components – meaning a failing alternator can shut the truck down completely once the battery drains.
Typical symptoms include a flickering battery icon, unstable headlight brightness, belt squeal or alternator noise, and hard starts caused by insufficient charging. Any of these signs means your alternator needs immediate attention. Ignoring the issue can leave your truck unable to start after a stop or, worse, stall in the middle of the route.
LKWHelp24 offers fast, professional alternator repair and replacement for all heavy-duty trucks throughout Germany. We operate 24/7 and support a large nationwide network with parts always available. Our technician starts with a complete diagnostic – voltage testing, load checks, regulator and diode evaluation. Many issues can be resolved on-site: belt replacement, installing a new voltage regulator, fixing loose contacts, and more.
If the alternator is beyond repair – seized bearings, burned windings – we replace it immediately. We carry both OEM alternators and high-quality remanufactured units for MAN, DAF, Scania, Volvo, Mercedes, Iveco and other top brands. A full replacement takes about 1-2 hours with belt tensioning and charging verification. We always check charging voltage (around 28V on a running 24V system) to ensure the truck is fully restored.
After the repair, your entire electrical system – headlights, starter, heater, fridge, onboard electronics – works reliably again. Our certified mechanics prevent repeat failures and provide maintenance tips to extend component life.
With LKWHelp24, your truck never stays without power. We respond day and night, reach any location in Germany, and get you back on the road fast.
Professional starter repair, rebuild, and replacement service
The starter is the electric motor that gets a diesel engine spinning. If it’s dead, you’re not going anywhere – turn the key, nothing happens, the rig just sits there. When a starter fails on the job (loading dock, fuel stop, whatever), your schedule goes off the rails and you’re stuck waiting for help. Common signs? Just a single click from the solenoid, the starter turns the engine too slow like the battery’s dying, or there’s zero reaction at all. Sometimes it cranks for a couple seconds and quits before the engine catches. All of this means trouble – worn brushes, low voltage, bad relay, or a mechanical jam inside the starter. If that happens, don’t waste time cranking it over and over – it needs fixing.
LKWHelp24 handles fast starter repair and replacement for heavy-duty trucks anywhere in Germany, 24/7. Our mobile crew shows up at the breakdown and gets right to work. First we check the power supply – lots of “starter problems” are actually dead batteries or corroded terminals. If that’s the case, we’ll jump it or clean the contacts. If the starter is the real issue, our tech pulls it out and checks everything. Most of the time, starters can be repaired roadside: new brushes, tightened connections, fresh relay, Bendix replacement – whatever it takes to bring it back. This saves you hours and money. Once rebuilt, we reinstall it and test-start the engine – usually it fires right up and you’re rolling again. If the starter is toast (burned coils, cracked housing, destroyed gear), we put in a new or rebuilt unit. With our nationwide parts network, we find the right starter fast – MAN, Volvo, DAF, Mercedes, Scania, Iveco – any model. Swap is quick, and the truck is ready to run. LKWHelp24 works nonstop, so even if your starter dies at 3 AM on an empty parking lot – call us. We’ll get you moving again. Fast fix, minimum downtime, guaranteed start.
Advanced computer-aided diagnostics for all truck systems
When a heavy truck starts acting up, every driver knows the risk: without proper diagnostics, the entire route can end on the shoulder. Modern trucks rely on complex electronics, sensors, and control systems. Even a minor fault can quickly turn into serious issues with engine power, braking performance, air systems, or fuel equipment. That’s why you need full computer diagnostics – a professional truck diagnostic service that detects problems before they cause downtime, missed deadlines, and financial losses.
LKWHelp24 provides nationwide truck diagnostics across Germany – on the road, at rest areas, parking lots, depots, and logistics hubs. We offer both workshop diagnostics and mobile on-site diagnostics for all major brands: DAF, MAN, Volvo, Scania, Mercedes, Iveco, Renault Trucks. Our service is built for carriers, fleet operators, and long-haul drivers who need fast, accurate, and reliable diagnostic support.
Our technicians use dealer-grade diagnostic scanners to perform a complete electronic inspection: fault code reading, engine and transmission parameter analysis, AdBlue system diagnostics, pneumatic checks, electrical system testing, and full evaluation of the truck’s electronic architecture. This is not a simple visual check – it’s a full technical intelligence scan of your truck. You receive detailed findings, clear explanations, and expert recommendations for repairs and further maintenance – the level of a premium truck service center.
Professional repair of truck air systems and air compressors
Air leaks, cracked airlines, frozen moisture, or a failing compressor can stop a heavy truck on the spot. With no air pressure, the braking system and air suspension shut down – the truck becomes completely immobile.
LKWHelp24 provides fast on-site air system repair anywhere in Germany. We locate the leak, replace damaged hoses and fittings, restore connections, and test all valves and compressor output. If an air spring is blown, we replace it or temporarily isolate the circuit to get the truck moving again. After the repair, we build the system pressure back up and verify that the brakes and suspension are fully operational.

Renault T Brake Fault in the Hills Around Calw
It was a grey September morning and Stefan, a Swiss driver, was working his way through the Black Forest foothills on the B295 near Calw when the ABS warning light came on simultaneously with a brake pressure drop alarm on his Renault T. He had a part load for Pforzheim and pulled off carefully onto a forest road turnout about three kilometres east of Calw town centre.
LKWHelp24 took the call at 9:07 a.m. and a technician arrived in 41 minutes, navigating the narrow B295 from the Herrenberg side. The fault traced to a cracked brake hose on the front axle that had been rubbing against the chassis over time. Brake fluid had started seeping, reducing hydraulic pressure. The hose was replaced, the system bled thoroughly, and the ABS sensor connection at that corner was also reseated as it had vibrated loose.
Stefan drove carefully through Calw into Pforzheim and arrived only 90 minutes behind schedule, well within acceptable range for his customer. The B295 through Calw and Herrenberg winds through terrain that amplifies any brake issue, making a quick mobile repair response essential rather than optional.
Our mobile truck repair in Calw covers the B295 route and the surrounding Baden-Württemberg hill country including Herrenberg, Pforzheim, and Boeblingen. The LKWHelp24 truck workshop in Calw is available 24/7 for all commercial vehicle emergencies. Reach us at +49 160 575 3826.

FAQ
Turbo blew on my Scania R outside Calw on the B463 at dusk. The tech arrived in just over an hour, swapped the unit on-site and I was back moving before 23:00. Outstanding.
EBS fault warning on the MAN TGX near Calw. LKWHelp24 came out quickly, recalibrated the sensor and cleared the fault without any towing. Very good night service.
Air suspension bellows split on the Iveco near Calw on a Sunday. Parts took a bit longer to source for this model but the repair was solid and the price was fair.
Cooling system leak on the Volvo FH heading through Calw toward Herrenberg. LKWHelp24 traced the hose fault and repaired it roadside within 90 minutes. Very professional.
