Working on a friend's Passat wagon, and he wants me to replace the turbo to fix the code. It 'may' be the turbo, but I want to make sure before throwing useless parts at it..
I've read on here many times that it could be the turbo, a boost leak, the MAF, the EGR, N75, the wastegate, etc. I've vacuum and boost-tested the wastegate, and it seems fine, moves freely, and will hold boost/vacuum.
The car has 393K on it and I'm unsure of the previous history, other than it was a one-owner before he bought it a couple years ago. It's been sitting now for almost a year, as it was going in to limp mode constantly.
I ran VCDS and pulled the P0299 and P0101. I saved the file, cleared the codes, but can't get them to reappear, as he stated was pretty easy to get the codes to come back; I just can't duplicate it just yet..
Having not a ton of VW diesel knowledge (I work on Cummins diesels) and their quirkiness, what's a good avenue to go down, before we start throwing a bunch of unneeded parts at it?
Thanks in advance, guys!
