Lonsbury Garage

European diesel vehicles are known for torque and efficiency—but they also require precise diagnostics and the correct service approach. At Lonsbury Garage in Angola, IN, we provide professional European diesel diagnostics and repair with a focus on VW/Audi TDI, Mercedes-Benz diesel, and BMW diesel platforms. If you’re dealing with warning lights, drivability issues, or DPF/regeneration problems, we’ll confirm the root cause and recommend repairs that make sense for your vehicle and budget.

Common European Diesel Symptoms We Diagnose

If you notice any of these issues, schedule a diesel inspection:

• Check Engine light or diesel/emissions warnings
• Hard starting, long crank, or rough idle (especially cold starts)
• Loss of power or reduced throttle response
• Turbo/boost issues (underboost/overboost codes, whistle, poor pull)
• Smoke or abnormal exhaust odor
• Poor fuel economy or frequent regenerations (as equipped)
• Overheating, coolant loss, or heater performance changes
• Fuel, oil, or coolant leaks

European Diesel Diagnostics (No Guesswork)

European diesels use advanced sensors and control systems—so accurate diagnosis matters. Our diagnostic process may include:

• Computer scan for engine and emissions-related faults
• Live data review to evaluate boost, fuel, temperatures, and system commands
• Visual inspection for leaks, cracked hoses, wiring issues, and heat damage
• Boost/charge air system checks to locate leaks and restrictions
• Cooling system testing to confirm pressure integrity and correct operating temp
• Road test verification to confirm symptoms and validate repairs

VW / Audi TDI Service & Repair

TDI vehicles are efficient and fun to drive, but turbo/boost and emissions-related issues can cause warning lights and drivability problems. We commonly diagnose concerns such as:

• Boost leaks (intercooler plumbing, hoses, clamps)
• Turbo/boost control faults (as equipped)
• Glow plug system faults affecting cold starts
• DPF/regeneration concerns and related sensor issues (as equipped)

Mercedes-Benz Diesel Service & Repair

Mercedes diesels combine comfort with torque, but drivability and warning light concerns can involve multiple systems. We can diagnose common issues such as:

• Starting and glow plug faults
• Turbo/boost performance concerns
• Fuel system and sensor-related drivability issues
• DPF and exhaust/emissions warnings (as equipped)

BMW Diesel Service & Repair

BMW diesels deliver strong performance and efficiency, and they benefit from correct diagnostics when warning lights appear. We support BMW diesel concerns such as:

• Boost leaks and airflow concerns
• Fuel system performance issues
• Cooling system testing for leaks and overheating symptoms
• Aftertreatment/DPF-related faults and regeneration concerns (as equipped)

DPF / Emissions Support (As Equipped)

If your European diesel is showing a DPF light, reduced power, or frequent regen events, the issue may not be the filter alone. Short trips and idling can prevent successful regeneration, but sensor faults, exhaust leaks, and engine performance issues can also contribute. We diagnose the full system so the fix lasts and you avoid repeat warning lights.

European Diesel FAQs

Why is my VW/Audi TDI losing power or showing a boost code?

TDI power loss is often linked to boost leaks, sensor faults, or turbo control issues (as equipped). We use scan data and testing to confirm the cause before recommending repairs.

Why does my Mercedes or BMW diesel have a DPF light?

A DPF light can be caused by driving pattern (short trips), sensor faults, exhaust leaks, or engine performance issues that increase soot. We diagnose contributing causes so the problem doesn’t immediately return.

Can you help with hard starts on European diesels?

Yes. Hard starts can be related to glow plug system faults, fuel delivery issues, sensor inputs, or other engine management concerns. We test and verify the cause before recommending repairs.
