Ok, hard to explain.
But say im in traffic, i put it in first, do an eager start, then put my foot down on the clutch to coast to a stop.
or
driving hard(ish) then have to put my foot on the clutch because something has come in front etc...
...the rev drops almost sounding like its going to stall, then jumps up to 1400revs or so.. then kind of hunts around... dropping and increasing.
Sometimes if i don't come to a complete stop it carrys on, or i have to engage the clutch and off again for it to stop..
any ideas?
-
Have you tried VCDS'ing it? Sounds like a sensor is playing up, or possibly a dirty throttle body
-
I don't have it, However, Im hoping to get to see Rick soon who does. I don't know if he knows how we check that, any guide?
-
Do an Auto Scan of all controllers, or you can be specific and just check Engine 01 then Fault Codes
-
Thanks mate
If i can, ill do the whole lot!! always felt a bit funny after the cambelt change.... :-\ any chance that could affect?
I was thinking of trying STP Complete Fuel System Cleaner or something.. any opinions?
-
Its possible, but hard to say without looking
That stuff isnt particularly brilliant...its just pretty looking REDEX
A decent can of Fuel Intake/Carb Cleaner will work nicely, though im sure its probably a sensor
-
Hi mate i had the same issues as you speak of and nothing would show in fault codes pn vcds but after some time i narrowed mine down the a faulty DV, so it might be worth having a look at that aswell :happy2:
-
hmm, mines been changed to a forge.. but interesting.. i will try putting the old one back (D)
-
I had a forge unit on aswell when mine was doing this :confused: im now on a evoms DV and had no issues what so ever, might be worth just putting the old one back on to see if the issue is still there, if its not i know forge to a service kit for the DV's with new rubber seals and grease so that might be an idea to :happy2:
-
interesting!.. did u find out what was wrong with the Forge??
Whats the evoms one like? £££? from?
-
I think it was sticking and that was what was causing the rev to dip etc, the garage were i had to changed from said they have had this a few times with the forge units, i paid £100 for the Evoms DV, but i know quite a few people on here are running the newer DV P/N 06F 145 710 with no issues at all aswell
-
If that's the REV D then yea, they do. i just got a lot of flutter sound at high boost like it wasn't holding it, hence the change to forge..
-
Iv never tried one of the Rev D DV's, might be worth just trying that if you have already got it so see if it cures the problem, and speak to forge about a service kit im pretty sure its FOC
-
I have a kit, but to be fair it seems to be so much hassle the forge,, not the first issue..
causes flutter too.
Ill give the D a shot and see... hopefully that will kill the lack of power i believe im having too :fighting:
-
The Rev D is a very solid DV. Mine boosts much harder on the D than it did on the B i was running previously.
-
Yeah that was once of the other reasons i brought a Evoms, just seems a simpler kit and it does it job well, its abit noisey if you have got an open cone filter on mind you under boost :grin: :driver:
-
but can it handle 350bhp.. id be supprised if vw built it for that?
-
I would have thought so. They use the same on the S3 and thats already a higher output
All you can do is try!
To be fair, theres no diaphraghm to fail :happy2:
-
Don't know what the boost runs on that, but a remapped ed30 is around 23PSI.
Will give it a shot again, but i remember why i changed it in the first place. (as above) least it may rule out some of these issues... then go from there..
-
Sounds like the PCV. Mine did the very same.
-
Did you feel lack of power, or pull\turbo kick in?
-
Mine is DSG however
-
Sorta, drops lower and quicker.. not on idle tho, only once driven and clutch down like my initial explanation.
-
sounds like a dodgy lambda too me
