• After tightening a second time, the attachment point of the countersunk bolts in the sensor wheel is so deformed that the bolt heads are at the crankshaft -3- -arrows- and the sensor wheel is loose under the bolts.
• Installing the sensor wheel is only possible in one position - the bores are offset.

-- After replacing the sensor wheel perform an adaptation using the Vehicle Diagnostic Tester.
