Title: Have searched, but can't find nothing exact, few niggly things!
Post by: ryanegg on 21 July 2009, 21:46: Mpg is very very low, even when changing gear under 2000 revs, only getting around 22-24mpg. About 28 on a longish run. Temp sensor seems fine.

Another thing, when my car is idle, the revs are either quite low, or quite high, havent a clue what it is.

Any ideas?

Car is a 1.8t btw!

Thanks in advance.

Easy enough to fit myself or is it a garage job?

Post by: Mr_Orange on 22 July 2009, 17:25: Aye, just get a cheap scanner off eBay. Scan the ECU for codes then get your wallet out if anything related to the MAF comes up. Code 16486 is a classic there!

I was in VW t'other day and a new MAF was £80 ish, including a trade in on the old unit. Gulp!
