Hi all :-) great forum!! I have a E34 93mod 525ixa 2.8L Hartge tuned.... last service on the car ,the camshaft got set to original 525ixa setting NOT 2.8L Hartge setting...I now got a real "mismatch" between VANOS and the camshaft.. I have tried to get som tecnical data from Hartge to get the car adjusted correctly. But i get no response on several faxes/phones or emails... im Pretty stuck here.... Anyone witha a good idea?????
