📝 ‘Adrian done my T5 VW Transporter – very knowledgeable man! Since then the engine is a lot quieter, runs better, feels more responsive & don’t smell of unburnt fuel. His machine picked up I need a new thermostat & a cylinder injector pressure valve was faulty jobs are booked in for repairs. Highly recommended!’
⚠️ Vehicle not as quiet, smooth, responsive or economical as it used to be? Smoking issues? Not running right?
🚙 Here we have a VW Transporter 2.5 TDI (2005 – 269,542 miles) booked in for diagnostics and Engine Carbon Clean.
ℹ️ The owner booked us in due to having smoking issues, poor fuel economy, a limp mode issue and given the age and mileage wanted it cleaned up also.
🔎 Initial inspection found a quite heavy smell, a noisy engine and not running particularly smooth, but no obvious leaks.
💻 Initial diagnostics found a code present for Cylinder 5 Pump/Injector Valve Control Limit exceeded.
📊 Live data monitoring showed a number of issues. Looking at the injector fuelling it was showing injector 5 in excess of 2mg/stroke and after already being at maximum learning limit was over fuelling considerably. The other main issue was that even after being driven for 10 minutes before we arrived the coolant temperature was only at 58°C. We warmed it up as much as possible and got it to a temperature where it would clean properly, but its clearly needs a new thermostat.
👨🔧 On with the clean and due to running cool it took a little longer, but by the end was much quieter, far less smell and much smoother and responsive.
ℹ️ The injector was still over fuelling indicating this potentially needs replacing. It was still not running at its best due to running cooler than it should so with both of these issues addressed along with the clean should be running much sweeter.
