Hi guys,

A few months back I was having some throttle related issues, basically the standard ones where the consensus is diverter valves or MAF. I thought to save messing around I would buy the diverters and the MAF to make sure, this fixed the problem. A few days ago the throttle issue has came back but different this. I think last time I had a MAF issue as the power loss was more consistant but this power loss is happens around 3000-3500 rpm, the power fade then comes back. I think the diverters have gone what do you all think, also will I be able to return them to audi as they are genuine parts just bought through VAG parts?

Cheers in advance.

Worth a shot in my opinion

Have you pressure tested the DV's to see if they're at fault and not something else? You need to get a top end pressure test carried out.

That begs the question where do i go for a pressure test and how much would it cost???

Nearest place to you that I can recommend is Grizz @ unit20 (over near Liverpool) ... http://www.unit20.org

Audi won't accept parts that were purchased from VAGPARTS, they won't even accept if they were purchased from another Audi franchise.
