Hi, I have an Audi A4, B6 from 2001 1.9 TDI 130 bhp, the motor code is AWX ( will confirm when I get home ) So I have a small oil leak ( will go to a service on thursday) and when I go over small puddles if I get some water splashed under the car the turbo won't enter anymore for like 1h ( I think until it or something else dries up). I went on a small trip and went through a lot of water there but the turbo made an heroic stand and stopped after 30 min ( enough to get out of a big storm with water over 1 inch in road ). I arrived at home and after 6h want to go to work but when I put in 2nd gear I can't rev the engine. It won't go over 1700 rpm and died if I didn't hold the clutch. I put the car in neutral and rev it a little, something like a white-grey smoke was coming out of the exhaust. And I tried to have a constant 2300 rpm but the engine went to 2100 on his own, and I think I heard something at the engine. If I hold it under 1700 rpm the engine behaves like normal, but the turbo wont come in and it gets hard to rev up while driving. The oil level is right and it has the classic black color.
