Question about 2000 Volkswagen Jetta TDI
I am getting a sae 1556 engine code The book says charge pressure control negative deviation I don`t think turbo is working Thanks email@example.com
It sounds like the turbo boost isn't being controlled properly, but this could be due to several things. Check for splits in the air pipework, and then get the N75 valve checked out - this is the item that opens the wastegate on the turbo, effectively shutting the turbo off. Oh, and check that the wastegate actuating lever isn't seized up...
Hope this helps you a bit. D.
