cupra dies and comes back to life

[SNOWZ]

This has happened a couple of time now,

The car drives fine, no ecu light and it just dies, as if its stalled and then about 10 mins later it starts again fine and still with no ecu light on.

Its happened a few times now twice at junctions or at lights when waiting just stalls then wait about 10 mins and also when it was in motion it just died, at the time it was driving normally not racing.

Anyone any ideas???

Sorry I cant help but going by the thread title, Id rename your car Jesus.
Actually, Id be getting vagcom onto the case and failing that, check the cabling and voltage to the ecu.

 

[SNOWZ]

i call it more than that but cant swear on the forum..

Just looking now to see if i can find anyone local to me to use there vagcom as i haven't got it

I had a problem like this, but it turned out to be a combination of a split boost hose and a dodgy maf, but i would sugest getting it on vagcom

i've replaced all the vacuum pipe with forge ones as they was perished, i dont know about boost pipes but i think i should hear and feel if it was split and shouldnt stop the car or stop me from starting again, as for MAF i was wondering if it could have something to do with it

still waiting for help with vagcom

 

[chrissy1502002]

yeah depending how big it is you should hear it and almost certainly feel the loss of power, but as i say i had both of the issues, but i beleive that the maf was causing it to stall when idling, but if i gave it any revs, it would be fine

 

[SNOWZ]

no loss in any power drives smooth, and when it dies its instant and no chance to apply any revs its as if it has an off switch and someone turned it off

 

[chrissy1502002]

have you tryed disconnecting your maf and tryed it with it off to see if there is any improvement?

 

[nogutsnoglory]

have you made sure that all pipes are tightened, check the turbo to charge pipe hose has a proper jubilee clip on, and all the little ones, even the one off the top of your dump valve has a zip tie on them.

last week i replace all the vacuum pipes for forge silicone ones and ziptied everyone to prevent them falling or forced off.

cant disconnect MAF as it doesnt happen all the time so cant see how that would make a difference, the car runs fine and boosts well haven't noticed any change in performance

 

[nogutsnoglory]

you do need to get it vag com'd
im guessing the speed sensor but think you should go over your pipework and check for kinks or loose connections

why would the speed sensor cut it out when moving and stationary and stop it from startng straight back up?

i'm struggling to find anyone local to me or within traveling distance to help me out with their vagcom

 

[cus]

mine did that and i had water in my ecu. worth checking?

will put it on the list to check, even though its been dry here for long time just cold brrrrrrr

 

[cus]

i'm hoping for you its not a new ecu anyways just worth a check anyways.

its under the scuttle panel on the driver side if you didn't know

yeah me too the mrs is already complaining about it as it keeps happening to her and she dont trust it anymore else it will be bye bye cupra

mine wouldnt start couple of times left for ten then it would turned out to be crank sensor your,s may not but just sayin

did it just cut out on you or you couldn't start it when it was not used as in parked up??

 

[Reuvers]

shouldn't be a hose, as if it was, it would have the problem all the time, and not occasionally imo.

wheres the crank sensor mate??
