Title: Help p0299
Post by: adgti on April 09, 2013, 07:20:16 pm

So today I decided to change my diverter valve to the latest revision G. Fitted it took the car up the road & I got a sound like a high pitched sqeel like a boost leak? Anyway drove another mile then I got a massive missifre with a cel turns out the coilpack has gone luckily I am having them recalled on friday. Any ideas on a boost leak?

Have you tried re-fitting the DV? Might have not been set in correctly

To be honest no but it looks ok. I will remove & refit tomorrow though

Check the joint from the inlet to turbo, this often causes squeel noises when not sealing.

Also make sure the DV is on correctly, it has a small locator bump on it that must be fitted in the correct location on the turbo housing.

hmmm could be that as I have also just fitted a CAI. I have removed the dv again & put it back on the same way I took the old one off. Although when I took the new one back out it fell apart  :confused:

Checked intake to turbo pipe it's all tight. Really can't find the leak I think it's from the pass side

Make a boost leak tester, I think you can do this with coloured air/smoke into the intake?
