V50 Engine D5 : - Random Non starting

Jon TDI · Nov 3rd, 2012, 22:49

I have a problem:- every now & again my V50 D5 won't fire up.
I've noticed it happens randomly on a "hot" start ie, engine will fire up fine from cold but when stopped & then trying to start again.

Eventually, it will fire up but it's very frustrating! Any ideas??

Flap sticking in throttle body, needs cleaning, plenty of posts on here as to how to do it.

Seen a few posts on cleaning the throttle body for the 2.0D.
How easy is it to clean on a D5 2.4?

It won't be the throttle flap on your car mate as its an electric throttle unlike the small diesel engines I would get the codes read first as it is more than likely it will point to where the fault lies!

I cleaned mine on my 2.0D and still have an intermittent start issue. Could be anything from a dodgy glow plug or bad injector.... Before I start going mad and buying this and that I'm going to get mine terracleaned and go from there. If its something ignition side then a terraclean will sort it out.

now then Noj ......ever thought it might be the switch on the clutch?

Clutch has to be depressed to start.

Alright mate, I always start up with clutch depressed as a matter of course.

I'm thinking maybe it's fuel temp/pressure related. Haven't got a code reader but going to put some Forte diesel treatment through the fuel to see if it cleans the system.

me too but the V50 won't start without it. Tells you on display.

I have a temp sender prob on the anni ...... starts ok just does random
surging and idle things.

Might invest in a cheap code reader to see if there is any fault codes.
Problem happens when engine is warm- after say 10 mins parked up.

does key not need a good battery to give a signal to car?

they are electronic and not mechanical ......

try using your spare mate.
