Volkswagen Transporter - Engine turns off, stalls | HELLA

If the engine in the above vehicle sporadically stalls or cuts out completely, this might be caused by a faulty Hall sensor in the distributor.

The following error codes may be stored:

In the immobiliser system `the same as':

- 17978, `Data cable faulty, implausible signal, engine control unit, immobiliser active`.

In the engine system `the same as':

- 01087, 'Engine control unit basic setting'.

- 00546, 'Diagnosis interface/wiring harness faulty'.

The preventative measure/check [adjustment of the engine control unit on the immobiliser (in menu Basic Setting/Coding for engine control unit of mega macs)] causes the motor to start up again, however the problem with the engine turning off/stalling reoccurs. The above-mentioned "misguided" error codes could include inconsistent signals caused by a faulty Hall sensor.

To perform a long-lasting repair, the distributor must be completely replaced as Hall sensors are not available individually.
