no i havent had it VAGcom yet, im very reluctant to pay for that until i have tried the simple things like both relays and throttlebody etc. going to also have a good look at all hoses etc in the daylight tommorrow

also after reading a few threads about this im not sure if VAGcom picks up the crank sensor fault?

ok tried a few things this morning. tried to resolder the ecu relay which had dodgy soldering on and also de-carboned the throttle body and checked for possible air leaks. took the car for a test run surprise surprise when it was up to temperature it cut out. was a simple test run of about half a maile and it managed to take me 20 mins!

suppose next up will be to buy a brand new ecu relay from vw and see if that makes any difference!

does anyone know if there is any way to check the crank sensor to make sure its working correctly?

i had the exact same problem on my mk3 gti 16v and it was the speed sensor/crank sensor. It would cut out on me on deceleration and one it had cut out it wouldnt start for about ten minutes. Then it would run for about 5 mins and cut out again first deceleration. Took it to dubsport they put it on vagcom and it showed the speed sensor had failed. They put a genuine vw sensor on and its been fine since (touch wood). Mine got to the stage where it cut out one time and i couldnt get it restarted at all i had to have it towed to dubsport.

Bunter: where did you download vagcom from. Its 235 pound to download off the vagcom site

ive just got to that stage, i got the car home yesterday after it cutting out twice on the test run after cleaning the TB and now it wont start at all! im hoping once i get vag-com hooked up il find out if it is the crank sensor or not. to be honest ive lost all faith in this car now and will be putting it up for sale as soon as its fixed, a real shame as i was really happy when i got it and it was a nice car to drive! guess il go for either a mk1 gti or a mk4 gti 1.8t, wel see...

fish6634 i downloaded vag-com from bit torrent although i understand you can download a shareware copy direct from www.ross-tech.com but youl have to buy a cable to run from your pc to your car.

I had the same problem as you bunter, i had it on VAGCOM and it showed the codes for both the crank sensor and cam sensor, i took it to a local VW speciliast who basically stripped it down it turned out to be a Key gear?? that had become damaged which was making the car start irregulary which in result didnt let me actually start the car, the crank sensor and this gear has been changed.

The car now runs properly as im getting 37mpg on a motorway run.

However it did cost me Ã‚£450 to repair (including a new cam belt)

im still waiting for the cable i ordered from ebay to come but once it does im pretty sure its going to say the crank sensors gone. the crank sensor was reaplaced on the car by the previous owner 3 years at a huge cost at his local vw stealership. just goes to show how crap vw parts and vw themselves are getting. seems theyre no longer reliable as they claim, i personally dont think much of them anymore, certainly not the reliability of cars after 1991

ok well, after finally getting my vag-com obd cable through in the post yesterday, ive finally been able to hook my laptop up and diagnose the fault on my car. turns out its a dodgy engine speed sensor, which is good news as i know whats wrong with it now but bad news is that its gonna cost me 40 notes to replace.

anyway heres the error i got from vag-com:

00513 - engine speed sensor (G28)
27-10 - implausible signal - intermittant

hope anyone else with the same problem goes down the route of getting hold of vag-com and a cable as its saved me the Ã‚£75 vw want just to do the same thing

Get this sorted bunter and then try to enjoy the car before you make the decision to sell it, once you iron out the niggles it can actually be a very good car.
