Coil pack on its way out of MAF dieing..

Have you had it on vag-com?

 

[cupra drew]

no mate cant get it on round here coilpacks are only bout a month old

 

[Damoegan]

...coilpacks are only bout a month old

Dont matter how old they are mate, could still be playing up..

 

[cupra drew]

have been told lamba and cts and also map wot about thease

 

[Damoegan]

Could also be the map..

At the end of the day all we can do is guess untill you get someone with vag-com to scan it and see if there are and fault codes.

yeah suppose so mate but will b going stage 2 nxt week so will this eliminate it being the map

I would just get it on vag com asp, then see what faults you get like Damoegan mentioned also check you maf plug see if its in all the way i know it might sound a bit daft

will av a look nw wot about the map question mate

 

[turbo009]

i am no expert,only guessing possibilities myself deffo needs vag com mate,i would also do that before you go stage2 next week.

just need to find sumone with it round here i would of thought with changeing the map it would eliminate it being that

 

[turbo009]

post something up on the vag com thread,i am sure there will be someone nearby you what would help

 

[cupra drew]

did that a while back and got no replys

 

[turbo009]

guess you can always go for your stage2 next week and hope it eliminate the problem, just that you really need it on vag com be nice to here somebody help you get it on. Hope you sort it quick

right you need to :

disconnect your MAF and see if the car runs better.. if it does then its your MAF

change engine temp sensor, only about 18 quid.

change coilpacks

vag com may say its a 02 sensor.. in that case it could be a lambda probe..

cheers fella just the advice i was lookin for ur a legend mate bbut the car runs fine anyway so dont no how i could tell its the maf

 

[tom w]

i had exactly the same problem backfiring / over fueling it turned out to be the maf . when i scanned my car it was thowing all sorts of codes like yours lamda sensor, running lean ,etc
