Audi A4 2.0tdi crank sensor fault
This Audi A4 Avanti 2.0tdi unfortunately decided that after every 15 minutes of running it would completely stop.
We diagnosed the fault to being a faulty crankshaft sensor. This component is small and very difficult to gain access to, but once changed it solved the problem for the car and the customer.
See just how tricky it was to get the sensor changed.
