Had a tinker with Swmbo car yesterday had to replace the front discs and pads on it no problem
Then she mentions it won't accelerate and goes into a limp mode if she tries to pull away too quickly brings up MIL so plugged the scanner in to find it is showing turbo/supercharger over boost fault I cleared this and decided to have a quick look for anything obvious .
Anyway after deciding it was not the weather to be laying on the floor playing cars I put everything back together
Anyway this morning 0700 she goes out and comes back about 10 min later and says the car is dead it won't rev or go over 20mph and it is my fault !! Anyway hooked up the scanner again and found code p0101 air mass sensor problem checked connector as I bought I may have forgot to reconnect it but it was ok quick google for new MAF £120 , then found out I may be able to just clean the maf with contact cleaner so worth a go .
After pulling the cover off the top of the engine to remove the maf and undoing the maf mount I found an old leaf stuck on the maf !
It must have got in there while I had the air filter out , anyway after again putting it all back together the fault has now gone
I didn't know you could clean MAF sensors there are even cleaners for this purpose I just used contact cleaner borrowed from work
