Hello everyone

i need some help with a vw sharan

until a few days ago it would start and then just cut off after some time but now it just dose not start.
when it was cutting off there was no spark as there is no spark now

do you think it could be the ecu at fault or am i missing something
any help would be appreciated

Thanks in advance

Next time it cuts out, check for a spark and fuel...If you have neither then the crank sensor is faulty...

Its burried deep within the fuse box and is a bit fiddly to change but its less than twenty quid.

Hey Guy's

I've been watching for a while, and it seems that guessing root cause is the order of the day. Check for fuel and spark one of you said, but then what - throw a crank sensor at it! Next lets guess at a relay. Agreed, both are common causes, but so is the coil, so is the key/immobiliser etc, etc.

How about some measurement and analysis? Roll Eyes

Car won't start - let's try and work out why, rather than substitiue/relpace our way to a solution.

It seems that 'pub bloke' logic is the order of the day here, you know "well a bloke down the pub said it is likely to be .................".

A fool proof mantra for quick accurate diagnostics is to test and not guess.

Cheers

Murdoch.

No guessing at all and I'm certainly not a "bloke down the pub", neither are the other techs who have offered help on this thread. I've been a tech for nearly twenty years and quite frankly find your post insulting. Relay 30 must be the biggest VW stopper but you'd know that already wouldn't you? I would suggest that you find relay number 30 and insert it sideways were the sun does not shine, I'm sure it will turn out to be one of the happiest days of your life.

Quite right, anyone coming into my workshops and asking me how to fix a Sharan will be told to book it in (where it will recieve some "measurement and analysis") or they will be shown the door!!!

Well I heard your a bit tight when it comes to your round!!

Motorwise, Motman and Rhubarb are highly respected members of this forum and certainly don't justify the title of Pub gossipers! Perhaps if the suggestions that they made were inherrantly wrong Mr Murdoch then it would justify your reply, However I think that the diagnosis that the members made were right, The non-start coulod have been either of the answers that they gave!!

you've been watching this site for nearly three years and the best you can come up with is this - have you really not thought of anything more constructive to say in almost three whole years - please tell me you've got more to offer - I'm sure you have - please don't prove me wrong

you could start by helping the thread starter (who probably has no access to a 'scope or scanner possibly not a even multimeter) how to go about addressing his non start - we've given him a couple of avenues to explore based on our years of experience and the fact that we deal with non starts on a variety of vehicles on a daily basis

without seeing the car it's difficult of course but I for one would be very interested to see what you would do next to get him going - for instance how would you (personally) go about about testing the immobiliser for instance
