Turbo Sucking Air

2 Weeks ago the dealer replaced the MAP and MAF sensors and put on a different air snorkel. Since then the turbo has been sucking air. Took back to dealer they made some "adjustments" all was fine for about 10 miles. It is now sucking air again. Any help would be appreciated.

Check the boots on the turbo-intercooler piping. If they've been improperly put together, they can pop apart under boost. You've got to clean the insides of the boots, and the outside mating surfaces on the metal piping. Use something to make the surfaces tacky so they stay together. Simple hair spray works.

Also, check the clamps holding the intake piping together, too. Maybe they screwed something up there.

I apoligize for not stating that the turbo is sucking air from a foreign source, like a loose or possibly a broke tube or housing etc. etc. etc. I assumed we all knew that turbos do indeed suck air from a known source.

Back to the beginning.

What exactly is the problem you are trying to fix? A code perhaps?
