engine cut out at 60mph!!!!!!!!!

[whit]

Driving to work this morning, coasting at about 60mph round a sweeping left-hand bend and I suddenly notice the rev counter fall to zero and the oil light come on!!!!! Probably only lasted a second or two before revs picked up again??? It was fine the rest of the journey and coming home tonight.

 

This has never happened before in the 7 years I’ve had the car. I’ve had the usual (dirty throttle butterfly) stalling problem in the past,   when slowing down to a stop but this is a bit disconcerting when you’re travelling at 60mph!!!

 

From what I read before when searching the web I’m thinking the coil is highly likely the cause of this, is that the most probable fault? Does that fact that it corrected itself (fired back up??), rather than me coming to a stop and having to re-start the engine, point to something in particular and I realise there could be a few different things to consider?

 

Any help appreciated as I don’t want it happening again!!

 

p.s. I did have a start-up problem back in October/November time, when intermittently it wouldn’t even try and fire up (no clicks – nothing) but then eventually it would just like that? Never did get to the bottom of that problem but since then it’s fired up 1st time every time!! Wonder if that was coil related or has any bearing on today’s problem.

 

Thanks

Dave

Im just going to take a stab in the dark as you had an ignition problem, maybe its that ruddy switch and u might have hit the keys with ur leg as it was a left turn.;.........

or fuel pump relay,loose connection? just guessing

Or ECU relay... I'm losing count of the amount of threads about these similar symptoms.... it's so easy to do I reckon the 30 and 167 relays should be changed as a matter of course first every time these symptoms occur if only to rule them out...

This forum saved my loads of money time and hassle when I had these symptoms... the ECU relay sorted mine out...

is there anyway of testing a relay?

how much do they cost and are they only available from VW because i can't see them on GSF website?

9v battery over the terminals if it clicks it works

that's the problem i guess as 99% of the time (if the relay is at fault) it will click.

how does relays work? how can they have an intermittant fault?

broken solder points.

A relay basically uses a low voltage to control a much higher voltage through lots of switching, so you can see why they phsically break down. They should be changed on any mk3 these days. Available from VW, 15-20 quid for both of them I think they were. They slot in to the top of the fusebox above the fuses

bit dearer than that.....just spoke to my local dealer

ecu relay = 9.66 + vat
fuel pump relay = 19.37 + vat
 
total = £34.11

are relays serviceable or do you just bin them?
