on motorway no pwer at all

[vw-8v]

i read the last thread and as i picking up maf tomorrow (missed the postie)  i will fit it and see if it resolves prob of judder and loss of power but if not ha ha ha i gonna b straded on motor way between glasgow and edin as through at girlfriends (prob started on way here) and hopefully it not the clutch but i dont know if the loss of power wld be down too the clutch?

if maf doesnt sort it i book in for auto elec to find a code.

Could well be the MAF or as per normal with these cars it could be a number of things but I doubt it would be the clutch with these symptoms.
If it was the clutch you would notice it slipping, where the revs go up but your not going anywhere.
Could also and may be what is known as limp mode, but I could be very wrong in saying that, so best wait until one of the more brainy members come on like Rhyso or Steve PD as they know there stuff about our cars.

well it wasnt the maf sesor at the post office depo ha ha it was repair manual lol cant hav one without the other i guess but had look and maf is simple swap.

yeah funny thing is when i started the car for return journey the turbo was working that is untill i was sitting aroud 70 and only put foot down a little to overtake lorry and it was as if turbo was blown out like a cadle (same noise) after that i struggled past the lorry and sat at 70 all way well struggled once got to hills(small inclines really) home no pwer at all. again this morn turbo working again all day but not been on long journey.

obviously need to wait till i get the mfa replaced but what is limp mode?

post if anyone knows and i do a search, guessing to do with ecu but would that cut the turbo??? as i know on motor bikes it just makes sure you cant rev past say 9000rpm it splutters and backfires. in the car revs will slowly slowly creap up when fualt there.

cheers

your car is going into limb mode, mine used to do it in the same situations. I just used to pull into the slow lane and turn the engine off and back on again
check all your intercooler pipes, not sure if a maf would put it into limp mode

Most likely a boost leak mate, check all the hoses for splits. My bro had a running problem on his tdi bora, it kept going into limp mode and that was the MAF so may be worth changing that also. His MAF was only £52 from vw so if yours is around that then might aswell try that aswell.

cheers for info maf on its way.

will check my manual as to where to find the boost hoses.

will update

thanks

Well the way I see it with me replacing my maf is if it sorts things out then it's all good if not then I just see it as a part that is worth replacing anyway as I bet most of our cars would be on the first maf from factory I reckon.
Mine is on 70k and i'm pretty sure it's on same maf as my bro had the car since 30k and he never replaced it.

well mfa replaced yesterday plus air filter pollen filter, was about to do oil and fuel but then the snow started so that for another day. but went for run on motorway b4 it got bad and as ever an eay fix did not work it still kicked badly then esp warning light came on and that was it , every little touch of the accelerator i got a rapid machine gun stutter from engine with no power but it was not in limp mode i dont thing as when it does tht turbo stops.

so as we speak i gonna try get out in the snow and hav a look for the boost hoses i also booked in for auto elec to hav a look at it.

grrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr just my luck lol i could hav spent extra money and got a 115 or 130 grrrr but then agian they might hav hed probs aswell.

[Rhyso]

rapid machine gun stutter could be an exhaust manifold blowing or the pipe going from the manifold to the EGR valve

I had this when I replaced the EGR with the Allard delete pipe but i didn't have time to remove the pipe to the exhaust manifold; the pipe eventually snapped off and threw the car into limp mode.  Blocked it off on the manifold itself and it fixed the problem

[vw-8v]

right i not sure how to go about that ?? where get pipe and silly question, if there no need for egr why it on the car? or what does the allard pipe do as egr bypassed? is there a link for intructions?

cheers as this prob annoying and if i can solve it b4 needing to pay money for auto sparky to plug vagcom in at 40 quid a pop.
