Turbo Question

[USMC_TOP]

This is not a H3 question but maybe someone here can help me. I have a 2001 VW Passat 2.0l Turbo. What would make my turbo pulse in and out under acceleration? Bypass valve?

possible failure of the blow off valve. can you hear the pressure releasing?

Boost leak. Check vacuum lines.

Vacuum line to the waste gate failed making the turbo surge?

I had a shop put in a good used engine 50,000 miles a couple months ago and all I did is drive it home and park it until today. I took it in for new tires and a wheel alignment This happens fast though, like every second. I'm not real worried because I called the guy who did the engine swap ad he said bring it in no charge. Even with the surge the engine runs very strong. Think it could be from sitting for a couple months like that?

That's not a surge. It's sobbing. It's sad that you sold the H2. :cheers:

 

[USMC_TOP]

It goes to the shop tomorrow, I'll let you all know what the problem is.

 

[USMC_TOP]

I haven't sold anything?
