Anybody had same issue and resolved ?

I have a 08 mk5 golf gt sport tdi 140.       
Owned this car for 5 yrs hassle free.     
Last month as I was driving car it just cut out and rolled to a stop, I tried starting and just cranked over and over and wouldn’t start.   
I called out the trustworthy AA and fuel pump was checked and then told me it was timing. Towed to garage and was told by mechanic timing was spot on and was crank sensor.      It’s been running fine then same thing happened today.    Just cut out and rolled to stop.
Turns over and will not fire up ??    I’ve checked fuses and all good 🤬🤔🤔🤔🤔

I’ve now changed the cam shaft sensor. , fuel pump. , fuel filter and not even trying to start just cranks over and over.       Any ideas ??

Read the fault codes?

As above read the fault codes. Could be a number of things.

But i wouldn't be surprised if a scan shows intermittent communication to engine ecu. The engine ecu relays are known to start failing and they causes intermittent starting or cutting out.




Relay A1 (1)  starts failing Hella 4RA 007 793-08 vw part 7m0 951 253a. Try tapping or wiggling it  with ignition on and see if it suddenly clicks and let's it start. Also remove it and check the contacts aren't corroded as seen this a few times now too.
