Every now and again car vRS seems to lose power. I dont seem to hear the same whistle from the turbo as when its running properly. If i stop and switch off the car for a few seconds the problem seems to go away?? Hope this isnt goin to be an expensive fix. :'(

That will more than likely be fault code 17705 (loss of pressure between turbo and throttle body.....Erm or something like that).

It can be something as simple as a leaking pipe (boost or vac), MAF, TB alignment, DV passing, faulty N75 etc.....or in some cases it can be a right PITA to fix because anything and everything that connects between the MAF and the TB can cause this fault.

Best of luck

Yeh, I have that 17705 code most of the time. I have replaced a few of the breathers and cant seem to find any others. Just really wanted to make sure it wasnt a turbo problem.
