Hi, I used to have a TT, and you could hear and feel it when the Turbo kicked in. I have just bought a A4 1.8T (2003) Engine code BFB, and does not seem to have any boost. There are no codes recorded, and not indicating it is in limp mode. Would appreciate a few pointers to look at please. Would have expected a ECU error code if the turbo is not working. I have not changed any parts yet, but hope the turbo has not gone! No abnormal smoke from the exhaust. Any thoughts would be much appreciated! Thanks!
