Hey All,
So my Ed30 hasn't quite been the same since its recent Major service (a few months back).
Currently, i am averaging 22mpg on my journey to/from work, which is 25 miles, but mostly urban. This is a definite contrast to the 27/29 i have been used to!
Also, from low revs the car feels weak, and rev-up is a little jittery (but only just noticeably so). Power also feels reduced in mid to high revs, and the activation of the turbo at the 2500rpm mark feels a lot more pronounced than it ever has before.
Checking for engine fault codes with VAG-COM shows no issues!!
I am expecting this to be a PCV failure, possibly also a MAF failure. However, doing the recommended PCV check of removing the dipstick while the engine is running causes the idle to become rougher slightly, then return to its normal idle (along with a whooshing sound of the air escaping) which implies to me that this isn't the problem!?
I'm about to book it in with the stealers who performed the major service, just wondering if anyone had any thoughts on the above, or could let me know something else i can test using VAG-COM that might let me know what the issues are before i take it in.
ta :)
edit: also, completely standard setup, no mods!
