SITUATION
The customer may complain about one of the following:
z
Rough engine running
z
Engine cannot be started (crank no start)
z
Check Engine Light illuminated
One or more of the following faults may be stored in the DME:
z
2A37 – Valvetronic, eccentric shaft sensor plausibility
z
2A47 – Valvetronic, eccentric shaft, signal plausibility
z
134E08 – Eccentric shaft plausibility (on F10, F25 vehicles only)
CAUSE
The VVT eccentric shaft sensor connector, and/or DME connector may have oil contamination due
to oil leakage at the VVT sensor gasket.
PROCEDURE
1. Connect a battery charger and perform a vehicle test.
2. If any of the listed above fault codes are stored, unplug the VVT eccentric shaft sensor
connector (X60253) and inspect for engine oil contamination.
Was oil found in the VVT sensor connector or the VVT sensor engine harness
