i had issues when the car was cold. i would accelerate and it would miss and wouldnt go anywhere
i changed the dump valve to a forge 007. the issue was 99% gone
latelly the same symptoms have come back. maybe not as bad but still there. sometimes hesistations through the revs
it doesnt seem to do it when its warm at all though. never has done.
i have checked over as many pipes as possible. replacing any that were abit dodgy.
there seems to be a pss noise like a dump valve in the engine bay. i gather a gentle whoosh is normal. it seems to come from around the injector side but its hard to pin point.
do the valves get noisy with age. my car has got 160k on the clock. its starting to make a weird noise from the cam belt or head area. once revved its not there.
-
sounds like a split vacuum pipe, might you have missed one when checking??
-
well i have checked as many as possible. especially around the injector area.
how come when fitted the dump valve it stopped? i did find a massive split in the pipe from the head but thats sorted. still no difference
-
when looking for boost leaks, oil is the easiest give away
-
there is a little around the injectors its always been there
-
have you replaced the top and bottom o rings on the injectors? you can get boost leaking from there
-
nope any idea what this entails and how i get them off.
-
you wouldnt loose that much pressure from leaky injector seals mine have been fooked for a while and i got full boost :wink:

When your accelerating is the turbo spooling?

er what does this mean lol?
i drove to work today and it didnt seem too bad
if i had a boost leak surely it would do it all the time, it never does it when warm

the point im getting at, is that you shouldnt be putting your foot down while its cold. i more or less ride the clutch until it warms up to at least 40-50!! i did once give it some when it was cold and it just coughed and spluttered!
So in summary, let it warm up before you give it anymore that 2500 rpm :wink:
-
I always wait for the temp gauge to et to 90 before giving it any
-
I wait until my oil temp gauge starts moving before I put my foot down :smug:

i very rarely go over 2500revs anyway. it does it from 1500 upwards. i need to put my foot down to go anywhere lol

Hi guys dont know as much about cars as all of u do!
but mine does the same on and off since I bought it, had an engine flush and hasnt been serviced too long ago, it can be fine for ages then all of a sudden it starts losing power and juddering when accelerating or at idle. although it seems like its clogged up then after a while of driving it it can clear and i get a huge boooooost and it goes back to driving like normal! any ideas????
Cheers Tamara

Any fault codes? boost leak or faulty ignition amp? :undecided:
-
The only fault code I have comes up now and then its temperature warning but happens mainly when car is cold, i then top up water chamber and it doesnt come on again for a little while, but i do have to do this more times than any other car ive had! only other problem im aware of is a small whirring noise for a second when i turn the car on (noisy starter motor possibly?)
not sure if any of these problems would be related but car started juddering today for a bit doesnt change if I turn it off and on again at all, but it did smell a bit funny today tho little bit like burning!!!!
How would I find out if there is a boost leak or faulty ignition amp tho?
-
Downpipe

does anyone have any idea. what all the boost pipes for the turbo are. so i can check them all
i seem to have a little oil around all the injectors.
i dont have any issues with running idling or when its warm. just sometimes when it pulls past 2k revs it stutters.
on the motorway its perfect as well
-
right the car is playing up now even on the motorway if you put your foot down you get a miss before it kicks down
i have replaced all the vacuum hoses as they were falling to bits with decent clips. it does feel like its revving better but still playing up a little.
does anyone know where i can get this pipe thats split? i have looked around but no luck

driving to london and back with gaffer tape and battery overflow pipe to use for the vaccum shows how bullet proof these cars are.
the whoosh sound is coming from the front of the engine. i did checkl the pancake pipe but the sounds nowhere near there. i have tried to check as many pipes as possible and except the vacuum and the pipe above all seem ok.
such a shame that many people have issues as these are great cars
i have no fault codes which doesnt help much lol
also does anyone know where to get the seals for the injectors and how hard they are to do?
-
creation motorsports on ebay do them, I'll be selling mine when my catch can arrives, where abouts are you?
