Ross-Tech’s VAG P0336 entry includes a missing-tooth description and a specific Audi A6 3.2-litre BKH wiring example. It warns that reversed sensor wiring can produce the fault on that application. The wording should not lead directly to an ECU replacement.
Keep the engine code with the waveform
The expected signal and circuit arrangement must match the actual engine. A voltage assumption taken from a different sensor type can condemn a healthy circuit. Record where measurements were taken and under what starting or running conditions.
If wiring was repaired, retain the pin-to-pin record and photographs where available. Ask whether the sensor output was compared with what reaches the ECU. That separates a signal-generation concern from a transfer or connection problem.
Consider the mechanical target too
The reference also discusses damaged impulse rotors on another application. A new sensor cannot correct an unsuitable or damaged target. Recent engine or transmission work therefore belongs in the history.
AXION can assess the electrical evidence for a supported crank-signal enquiry. Send the complete scan and any labelled waveform recordings. Avoid repeated sensor or ECU purchases without establishing why the reported pattern is wrong. The final check should reproduce the original starting or running conditions where practicable.
Arrange an assessment
For ECU testing and repair, send the vehicle details and fault report to AXION. We support enquiries from drivers and garages. Workshop, postal and remote options depend on the job and are confirmed before booking.
Technical reference
Read the supporting technical documentation. The referenced design or vehicle application defines its scope; it is not a universal repair procedure.
