Diagnostic Consultation and Engine Carbon Clean on a VW Transporter 2.5 TDI (2005 – 269,542 miles)

‘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.

Adrian is a lovely fella, explained the process, carried it out well, clearly done exactly what it needed to do as I blew a load of stuff out the back when I drove it after. Will definitely be coming back in the future.

Steve arrived to give my Jaguar xfs an engine carbon clean. Presently on 107,000 miles. Explained the process and was obviously very knowledgeable about the process and expected outcomes. And he was a thoroughly nice chap.
The V6 in the xfs is a quiet, smooth, powerful unit and I was not sure of what improvements I would get. Well, I’m impressed. The power delivery is smoother, the engine even quieter and 6 mpg better to boot.
If you want to do one thing to maintain and improve your motor, then this is what you should do.

Leon came out to my car about a month ago. He was brilliant, he did some diagnostics, asked some questions and then got to work sorting out my problem. He was extremely thorough and I could tell he genuinely cares about providing a first class service. Fantastic!

Iv had the pleasure of having 2 Carbon cleans from both Adrian and Mark. Both lovely gentlemen and you can tell they love what they do. My car failed on emissions and this helped me get the car through the test, and at the time, I REALLY needed a pass because I couldn’t get anywhere. These guys saved me. Not only that, it’s a lot cheaper here compared to other places also. Thank you so much and look forward to seeing you in future endeavours.
