I had my Mot done passed no problem 2006 5dr GTI.
BUT, I noticed the mot tester put a thermometer down the dip stick
. He had this running for 10-15min to bring the temp up. The car was running lumpy and sounded like air drawing in the dip stick chamber
. Would this damage my engine or pcv, becuse since then my boost is not brilliant, and not doing so good on fuel so i replaced my DV for a revision D. as i removed the revision C there was some oil over it, its running ok but still not good on fuel or turbo
Does anyone have any ideas. Thanks.
