3.2 V6 Idle Issue

Recommended Posts

Hello guys, 

Just got myself a 2004 A3 3.2 V6 with 102,000 miles, DSG. It's a great fun little car but it has an idle issue, it idles really erratically making it a nightmare to drive / reverse at low revs.
Is this a common problem? I'm no mechanic but I'm not too bad with the spanners so looking for advice so I can try and rectify the problem myself so any so any help will be greatly received.

Also looking at getting a working version of VAGCOM for not stupid money if anyone can share a link please?

Many Thanks

Dave

Hi Dave

I would start with running some cleaning additive through the fuel system and also try some cleaner through the intake as well.

Companies like Terraclean do a great service to clean out the soot and carbon build-up in the engine and have it running like new for not a lot of money.  http://www.terraclean.co.uk/

Lots of equipment available out there...take your pick    http://www.audiownersclub.com/parts-search-results/All/Vehicle_Parts_and_Accessories/131090/vagcom

Thanks for the advice, it definetly needs scanning hence why I'd like to get a work version on VAGCOM :) and try myself.
It's am odd one really but I don't think it's the chain (or hope it isn't)........If I start the car and don't touch the throttle it'll tick over fine, if I touch the throttle and then let it idle it is rough and will even die on occasions.

 

Thanks
