DPF light? Diagnostic consultation and Engine Carbon Clean – VW Golf 2.0 TDI (2007 – 149,629 miles)

⚠️ Just bought a vehicle? Vehicle not running as quiet, smooth, economical or responsive as it should be? Engine/DPF lights on?

🚗 Here we have a returning customer with a new acquisition – a VW Golf 2.0 TDI (2007 – 149,629 miles)

Having bought this about a week ago (and already planning to get us to clean it up) he called us for advice after the DPF light came on.

ℹ️ Although this could just indicate lots of recent short journeys on low fuel, it could also be down to faulty components such as DPF sensors, exhaust gas temperature sensors, EGR issues, thermostat, etc.

Knowing what this could potentially lead to he asked us to come and take a look asap.

🔎📊 Initial diagnostics showed no codes present, but multiple failed regeneration attempts. Backpressure up at 33mbar and soot loading at 64%. Coolant temps looked OK and again other sensors also appeared to be functional.

👨‍🔧 We hopped in the passenger seat and rode shotgun with the diagnostics to perform and monitor a regeneration whilst the owner drove the vehicle. After manually triggering the regeneration and watching the soot loading drop down to zero the DPF light stayed on for a good 5 minutes before the ECU recalculated the values and finally turned off the DPF light.

Once back home we then proceeded with an Engine Carbon Clean to clean up the source of the emissions. The previous owner had pottered around on poor quality fuel and the engine was rumbly and bass heavy, but by the end was smooth and quiet again. With a diet of better fuel and decent runs this vehicle should be fine.

🗣️ ‘Given it a good drive for about 20 minutes goes like a dream…drives so much better and a lot more power 😁’
