After I removed the hose from the AGR and sometimes so easily with the tongue to it, I noticed that it does not attract at all – with running engine. There should be underpressure on it? Where does the vacuum come from? That could then be the solution, why it so lamely accelerates, only from 2500 it goes right off… That’s the low pressure for a turbo with it. Monday I was at BMW – no chance, they don’t come in the control!!!! But he should just look at this and give me a hint. Do they don’t want to. Tomorrow morning I have another appointment with a FOH! Let’s see if he knows himself with such an “old” car. He said he knows the engine from earlier !!! Since I see in the beginning black. Can you push the under pressure system somehow on tightness? I also look forward to your comments. Greeting Robert CAR 2,5 DTI 4/03 – 215,000 u km of leather
