Special Notes
* In MY 1995-2002 (?) in Europe at VW-diesel-cars G70 had the bad reputation of slowly losing his performance, causing loss of power. It's not a matter of defective or breaking down, but it is filthy / dirty (not easy to clean). You can check functionality by making a log in [01-engine], [meas.blocks-08], group 003 (3e gear, full throttle, from 1700-4000rpm)
Possible Symptoms
* Absence of Engine Torque in lower RPMs
Possible Causes
* Fuse(s) faulty
* Wiring/Connectors from/to Camshaft Timing Adjustment Valve Bank 1 (N205) faulty
* Camshaft Timing Adjustment Valve Bank 1 (N205) faulty
Possible Solutions
* Check Fuse(s)
* Check Wiring/Connectors from/to Camshaft Timing Adjustment Valve Bank 1 (N205)
* Check Camshaft Timing Adjustment Valve Bank 1 (N205)
