Sharan 2.0 Petrol Running Problem

[victor meldrew]

My sons mk 1 petrol sharan occasionally refuses to start and is prone to cutting out.

I checked relay 30 and resoldered an obvious dry joint and it started fine.

Today the problem has returned, it occasionally cuts out and won't start then after a few tries it starts.

It seems to run rough until its warmed up.

I need to fix it over the weekend cos he's making silly noises about buying a zafira

Where should I start?

zaffy eh,er i made that silly mistake.if he is used to the size of the sharan he defo wont like the zaffy.

 

im tempted to say take a look at the relay again,as you said it worked after you attempted to fix it,either try fixing it again or buy a new 1.

I've had another look at the relay and it seems to be working, now he tells me its cutting out after driving through puddles.

I know there's no under tray on it so Im hoping its damp related, when the rain stops ill have another go.

ah ha,there is a problem.not advisable to run 1 of these cars without an undertray.

there are a few posts on the subject and iirc 1 of them relates to HAVING NO STEERING.especially when going through puddles.

 

think he needs to source 1 asap.

It was the coil pack tracking, I could only see it in the dark, that's fixed but I managed to break a vac pipe off
