⚠️ Engine Light or DPF light on? Don’t ignore it as it can lead to a blocked DPF.
🚗 Here we have a VW Golf 2.0 TDI (2009 – 102,733 miles) booked in for a DPF Clean.
❗ The owner had an engine light come on recently, had a diagnostic code read done coming up with an exhaust gas temperature sensor and had put it off before having it replaced. Once replaced at the garage they couldn’t get it to regenerate and the owner contacted us for a DPF Clean.
🔎 We arrived and initial inspection of the engine bay confirmed a bass boom present from DPF backpressure.
📊 Initial diagnostics found no codes apart from the soot content code, and a soot content value just above the maximum level for regeneration to take place.
🔎📊 Before we proceeded with the DPF Clean we checked through all the other live data to ensure that once cleaned up the DPF would successfully regenerate again. Good thing we did…
🌡️ Unfortunately we discovered that it was running cold due to a faulty thermostat – at best at 81°C when revved with no cabin fans on and dropping to a chilly 69°C when idling with the cabin fans on.
⚠️ A cold running vehicle won’t regenerate properly or at all. There will typically be NO CODES present for a thermostat issue like this.
No DPF Clean today! Once the owner has the thermostat replaced then we will return and unblock the DPF.
