Since I first bought my 2004 1.9T I have had an occasional surging problem. It started to get worse lately so after searching in the forums I found some people suggested changing the coil/wires/plugs. I ordered all the parts and put them on but the problem still existed and as of about 2 weeks ago got even worse. I had no check engine light and my scan tool showed to codes in memory. I read in a recent post that someone said they fixed it by changing the Turbo Pressure Valve. I found one online from a Volvo parts dealer and it was only $40 USD so I decided to give it a try.

I installed it today and my car has never run better since the day I owned it. I no longer have the surge/studder problem and the turbo seems to be a lot stronger than before. It used to have a bit of lag off the line and then start to pick up. After installing the new pressure valve it kicks in instantly. The valve hangs right off the air cleaner on the firewall side and had 3 vacuum hoses and an electrical connector on it. It took me 2 minutes to change and made a huge impact on performance.

Anyone else having this problem, I hope this helps you out.

can you please give website or location where you found the part?

Click the link below it should take you right to the order page.

I took standard shipping and it was shipped really fast. I ordered on a Thursday and received it Monday.

It is a genuine Volvo part not after-market junk. It is $52 now, there must have been a sale when I bought mine, but sure to cost less than dealer.
