Most of the time the car drives fine.
However, after idling for a minute or two the car has no power as if the turbo is not boosting.
If the engine is turned off then back on it will drive fine until the next time I have to idle.
It seems to reset itself with the off/on so I dont think it can be blocked with soot etc

Any help please.

I would suggest checking for trouble codes for a start.

Hi STYPEJACK,

If you decide you would like to conduct the scan yourself here is a link to an article that features written step by step instructions and pictures explaining how to do the scan yourself. Also, I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com

Once you have the codes please get back to us so that we can further assist you. We are always happy to help.

Thank you for visiting 2CarPros.com.

Kindest regards,

Hi Thanks for you comments. I have been able to get the following codes P0235 P0670 P2002.

Also I noticed when I sit at idle for two minutes the injection fault comes up and the filter recycle light comes on?

The first code is telling us there is a boost problem which will point to the turbo going bad. Remove the intake or exhaust tube from the turbo to check the end play of the turbine shaft.

Please run this test and get back to us so we can continue helping you.

Best, Ken
