limited boost and traction control light :(

[cus]

hey was happily boosting yesterday,and thena pop!
checkedmy intercooler pipes and they are al fine. thought it must be my TIP, so put that back on, and drove home.

reset my battery for about an hour whilst i was refitting my TIP and.
then startedmy car again to find the tractioncontrol light came straight back on and its limited to 6psi
anyone know why?i've checked all pipes and vacuum pipes.

also idling is rough, it drops the revs too low and then builds themback up again.

just hada service a couple of days ago, and everything was changed, plugs, liquids etc.

i dont have VAG-COM, butdoes anyone have an idea what i can checkfor please?

it feels okay to drive, but dont want to risk it . thanks

Sounds like maf problem to me,

 

[cus]

i'm gonna dothe MAF test in a bit by unplugging it. if its a new MAF, do youhave to unscrew the old one, or do you get the casing as well?
anyone got a rough price fromthe stealers please

 

[M87NER]

Yeh you get the whole casing, its about £65ish iirc with exchange -

 

[cus]

just disconnected myMAF and itmade no difference
do i need to reset the ECU before trying this?

 

[gulzar]

my lcr did this few months ago, unplugged the maf and hey presto ran smoother. took it to steelers and showed the mechanic, who agreed, they replaced the maf under warranty and now all is well touch wood. good luck

 

[cus]

whenyou unplugged the MAF, did you disconnect the battery for half anhour first?

 

[M87NER]

sometimes it doesnt always work by disconecting maf, anyone near you have vagcom?

 

[gulzar]

possible coil pack failure then matey. you might need to get vag com on the case. however in my last car i replaced everything bar the maf when this happened. wish i'd changed the maf anyway. as u no these cars go thru mafs and coil packs at an alarming rate.

 

[cus]

i'll try and find someone with Vag-Com first thanks a lot for the help

so possibly the MAF or/and coilpack.
i'll also disconnect the coilpacks one by one when i get time.

is itokay to drive like this though? thanks

 

[gulzar]

wouldnt recommend it. keep it limited to taking it to get fixed in my opinion. M47NER apologies for jumping in there. thought i'd add to you opinion.

 

[freddie]

sometimes mine pushes the coil packs up just enough to cause misfire try pushing them all done tight and dont rule out possible spark plug failure even if there new.

 

[cus]

all sparkplugs have been changed, so will checkthem as well

no problamo...

 

[cus]

just pulled each coilpack out at a time and they all affected the engine, so must be working fine. disconnecting the maf seemed to make no difference. anyone else have any ideas?

 

[cus]

now you are all allowed to laugh at me.. feel free!

ran vag-com. and came up with 12 faults.

pretty much all apart from 3 pointed to earth issues.. replaced one of my fuses.. and its all working!
even idles properly and boosts fine now!



i'm very very happy! just ordered a coilpack as well.. oops lol

always best to have a spare though i guess

 

[dicko's]

marcus the leon was doing the exact same thing lol kept blowing engine management fuse and running wank etc sorted it now and its so much smoother and quicker

 

[cus]

hey mate. how did you managed to fix it?
mine is still idling a bit funny, but doesn'tseemto affect performance. so i'm happy
get your sig pic updated!
cya tomorrow anyway, text me to remind me topop around!
