starting problems

[paultdi]

hello i have owned my cupra150 for three weeks and now it has starting problems from cold when i try to start it with no throttle it is lumpy to 500 revs then konks out the only way to start it is hold it turning over and give it a little throttle then little rev seems to clear it but it chucks out loadsa smoke until it clears it has done 85k any ideas on how to fix this as im quite confident with a spanner just dont know much about diesels yet any advice would be great

just a guess, air filter then check the egr valve for goo for starters

 

[paultdi]

thanks il give that a go management light cane on today 2 any one got any pic of egr

 

[cheshire cat]

ther's one on here somewhere----- it's at the back drivers side of centre with a circular shiny top like a flying saucer with a small rubber pipe on a stub

management light came on you say? get vagcom on a laptop and see whats been logged for pointers

 

[tuckerjuk]

probs your temp sensor bringing on the light and causing poor starting, they cost around £20 and are easy to fit

oh this is interesting - I had a similar thing today, would turn over fine and the engine would seem to be starting then cut out. Check engine light came on and the glow plug light was on too. Tried 3 times and it did the same. 4th try I added some more throttle and it kept going - not sure if that was coincidence or not. I did notice the temp gauge going up and down (with the ignition on/off/on) very coarsly in little jumps - I have never looked that closely before but sure I would have noticed it not being a smooth.

Hopefully will get it in to the dealers later on today so they can at least see what fault codes have been logged - they dont charge just for that do they??

well it turns out they dont have the time to even look at it today which is effing useless I'll have to try and find my vagcom and see if the laptop I have it registered with still works, its all getting dusty in a box somewhere!

 

[tuckerjuk]

dealers will prob charge for a diagnostic

 

[paultdi]

Maybe your problem is your temperature sensor that brings you problem on starting. Kindly buy a new one that not consumes a big amount of money.

i meant that this topic goes back to 2007, hope it didnt take years to find and fix?

 

[paultdi]

stew no didnt take 2 years to fix just thought id better put the solution to problem in case anyone else has the same

 

[sssstew]

cool. thanks Paul. Very thoughtful. I recently had a member have a go at another member for not posting up results.... its not like you HAVE to do it, so we appreciate it when you do though

 

[oldman]

polite me thinks and what's point of not putting up the outcome / fix / results.
nothing helps no-one

so yes, thanks for putting up the fix for you paul.
i do try, but do get side tracked often due to work & more work
