Title: Wanted your opinion on the following issues...
Post by: DmjButler on 16 September 2013, 00:26
Hi all!

I'm happily back in a Golf GTi and I'd firstly like to mention she drives well! However I have noticed a couple of things which I wanted your opinion on...
1) the first thing I noticed (and this is intermittent) is that after driving the car and turning the engine off, there is an air "whistle" which lasts a couple of seconds and effectively sounds like something is 'winding down'.
2) when cold, the car starts first time but runs lumpy for literally a second or two then seems to idle smoothly with very very little idle fluctuation, it's worth mentioning that it does seem to be a little loud (in terms of engine volume) at this point.

I appreciate the best thing to start with is a Vag Com but I don't have one and only bought the car yesterday (privately) (if anyone in the St Ives - Cambridgeshire area has one I would be very grateful!!).. I wanted to get your views on the issues.

The car is a 2002 AUM with 79k and standard.

Thanks a lot!

Sounds like the secondary air pump (sai) is leaking
Look it up and look at either repairing it or blanking it off and removing like many others do.
