Engine keeps running when key is removed

1999 2.5TDi Box Bus

A fault has developed very recently where the engine keep runningwhen I turn the key to the off position. However, if I turn it back to position 2 (dash lights come on) the engine then turns off.

I also have an EML and the engine is in limp mode, but I don't know if these are related or it's a separate issue.

These are almost certainly related faults. The Electronic Switch Off Solenoid (ESOS) on your EPIC pump has failed and not reacting to the switch off command, this then puts up a pump fault and causes limp-home mode.
You can prove it by stalling the engine at the same time as switching off, and then it will re-start next time without the limp.

I'm not sure if you can still get the parts to repair the ESOS, but someone else will know

Suggest you have a look at my write up.

Plungers were hard to get for a while, they are easier now but have rocketed to a stupid price. I can check if I can still get one
