Gully Posted January 5, 2011 Report Share Posted January 5, 2011 Hi everyone one I'm having problems with my gti ed 30. The car seems to judder wen parked up and engine running on idle. I remember the same problem on my r32 mk5 but I didn't get round to solving the problem as I sold the car. Can any one out there help me on the problem Link to comment Share on other sites More sharing options...
Cuprabob Posted January 5, 2011 Report Share Posted January 5, 2011 It could be the sign of a coilpack on it's way out.Very common on all VAG cars. Although I would expect it to misfire under load as well whereas you're implying the issue is only at idle. If it's just at idle sounds like like an air leak somewhere. Get someone to run vcds on it for faults as that may give a clue to where the problem lies. Link to comment Share on other sites More sharing options...
Gully Posted January 5, 2011 Author Report Share Posted January 5, 2011 Thanks for response. The car as been at vw dealership as engine light come on dash they run a diagnostic on the car and found no fault then did a full wiring check and found the thrust sensor had packed in. But pior to the vw checks the car was stil juddering at tick over. And the fault was not discovered. It's got a little worster now and I am kinda Hopi g that it is the one ov the coils. But computer wil not pick this up until it gets worse. Link to comment Share on other sites More sharing options...
Cuprabob Posted January 5, 2011 Report Share Posted January 5, 2011 With it idling, if you disconnect each of the coil packs one at a time in turn. When each is disconnected it should idle worse. If you disconnect one and it makes no difference then that's the coilpack at fault. They are around £30 each at TPS Link to comment Share on other sites More sharing options...

TIDYDUBS Posted January 5, 2011 Report Share Posted January 5, 2011 (edited) What fault code was coming up do you know exactly??? What sort of fuel are you using? Could be a SOFT misfire that wont necessarily show a DTC. The other thing i have had with these are the injectors, rare......but can be sods for going down or just being lazy. As you probably know the FSI system and the solenoid operated injectors works under very high pressure controlled using Pulse Width Modulation(PWM). Fuel pressure could be an issue.? The other thing i have had is the breather valve on the front of the cam cover where all the big pipes go into it and some smaller ones too play up giving all sorts of weird problems also highlighting a MIL on. Rough idle, more often though increased idle and creeping up to about 2000rpm would be good to know your fault code though+++ Edited January 5, 2011 by TIDYDUBS Link to comment Share on other sites More sharing options...
Gully Posted January 6, 2011 Author Report Share Posted January 6, 2011 Hyia mate. No fault codes are coming up snd I'm using shell v power in my car. The car drives perfect part form wen it's left started on tick over. Vw av replaced the thrust sensor but that was due to engine management light coming on on the dash. But saying that I thought they might av come across this problem to as it was there before the sensor went they did a full diagnostic and wiring check and the only thing they found was the sensor. It could be either one ov the other things u mentioned but it ant showing up on computer. I've been told by my mate to let it get worste then computer will pick it up. But to tell u the truth it's annoyin and I like my cars to be running perfect. Link to comment Share on other sites More sharing options...
TIDYDUBS Posted January 7, 2011 Report Share Posted January 7, 2011 Top man on the fuel!!! Glad to see some people have sense.......hmmm is manual or DSG? Have you got the fault code for when the engine light came on, only it could be related. Also compression test and cylinder leakage test worth checking if all coils are ok. What sort of miles have you done. Ill have a dig around. Link to comment Share on other sites More sharing options...
Gully Posted January 7, 2011 Author Report Share Posted January 7, 2011 I don't know the fault code mate. But I could easy get it from vw. I'm still thinking it could be the one ov the coils. I've not really got round to check em as ov yet. The car as done 48000. The compression test is a good idea. And nice one to u for trying to help me out it's really appreciated ps it's a manual cheers again mate Link to comment Share on other sites More sharing options...
TIDYDUBS Posted January 9, 2011 Report Share Posted January 9, 2011 Cheers, much appreciated. I got a few things here if you get that code? Also your software may not be up to date? Link to comment Share on other sites More sharing options...
