our discovery has thrown up an odd fault. for some reason when I switch the ignition off it continues to run for a few seconds. any clues as to what to look for? engines and gearboxes I can deal with, but bloody electrics

Check for sticking fuel cut off solenoid

Graham Carter · Jul 31, 2014

I had a similar problem on my 300Tdi. It was a sticking solenoid on the fuel cutoff. Unfortunately mine was caused by the injector pump failing due to poor fuel quality, and shards of metal had worked their way through the system and lodged in the cutoff.

The other fault you can get is the wire to the solenoid fails, and then you get the reverse - put foot on throttle and the engine stops!

The fuel solenoid from memory is at the rear of the injector and has a single wire going to it.

Cheers!

Might have a security guard on it depending on the year as well
