Hi Sid about 10 seconds if that. If I start the car once and try to drive it there is no boost. But if I shut it off then start it backup. It seems to drive fine. So the engine is still cold at this point

Hi Steve. Thanks for reply. I understand that pipes can get old and leak. But. If it was leaky pipes. Then. Surely it wouldn’t matter how many times I start the car it would still not boost. But as long as I start the car twice. It will drive. Fine. It’s quite baffling.

Hi all I’m new on here. But just my 2006 a3 2.0tdi. Won’t boost when first start car if shut it off and start it back up it will boost fine. Until I shut it off again then I got to start it twice to get it to drive normal. No smoke. At all and can’t hear any hissing. Any suggestions would be appreciated. thanks in advance
