  • Had abit of a strange oddity occur last night on the trek home from work. The Passenger side window had a mind of its own and, continued in closing and opening, and engaging the window switch had no effect. Seems to have disappeared this morning though, must be a gremlin at work

      Got that fixed and got the ECU software upgrade as well. In the process of find out the fault for the turbo, VW dealership has diagnosed that I have an indication of possible fly wheel failure. Upon further inspection, new fly wheel is getting ordered to be replace.
      Funny thing is that I didn't know that VW have dual mass fly wheel and they they do come out of alignment which was why I was hearing funny noises after clod start, when pressing on the clutch noises disappear.
      Turbo is good now....
      Good to hear.

      I wonder if anybody else noticed it on theirs.
      It is sealed unit and I don't think it can be topped up.

      Yeah last service at Solitaire they found an oil leak near the gearbox/sump region.

      Car has done approximately 28-29K.

      • Heya guys,
        so my second GT TDI has a bit of an oddity about it. Occasionally there is a real flatspot up to about 2200 rpm, like the turbo is not making boost. Once above that rev range, it's fine - pulls very hard from 2500 up, every time.

        It's only intermittent.

        Boost leak maybe?

        • Rear clunk

          My new GTI (3000kms) has a persistent rattle that sounds like it's coming from the rear left corner of the car. Noticable over road imperfections and also at other times. No vibration etc, nothing loose in cabin / boot.

          Is this the tail light clunk, and if so (or if not), will the dealer investigate this FOC or will they sting me a fortune? I'd like it fixed as the car is awesome otherwise but this is driving me nuts.

          • I too have a rattle, which is starting to bug me! It appears to be somewhere in or under the drivers seat. When I break, I can hear it rattle/clunk. Almost as if a coin has been dropped down there. Pretty annoying!

                You're not driving it hard enough!

                When my PDF got a bit clogged, they regenerated it and essentially told me to drive it harder.

                Has it been idling at 1000rpm at all recently?

                • didnt think the coil packs had anything to do with the DPF? maybe im just noob hehe....

                    My R32 as well. Dealer check all mounts, bolts etc. Ive also checked all I can see
                    Only heard occaisonally when going over small road imperfections etc.

                    • Check back through this thread.... it is most likely the cord and bob that holds the parcel tray/cover in the back. When the hatch is closed the cord runs through the cover and the weight bob is what bounces around as it just hangs down and swings.

                      • It's not that - ive had that weight bob noise in the 2.0FSI and its a completely different sound. This is more prominent when it's a jiggly rough road, rather than over say speed humps etc.

                          • TSI s/charger wiring issue

Twice I've had the engine warning light flicker about 5 times and then stay off (I understand - from RTM - that this is an 'exhaust system' warning light; I'll be taking the car in this week to see if it is merely cold weather running, though I don't recall this happening last winter, which was about the same temperature)...

                            Perhaps worryingly, he said he identified the exact cause of the problem within seconds of driving the car (which suggests it may be a common problem).

The electrical harness wasn't long enough to allow for normal engine movement, so the harness was torn off. Not a problem for TDI's, clearly...

                            All fixed now, with a longer electrical harness which should avoid the problem re-occuring. Looking forward to driving it again tonight (and a return to that smooth power delivery...).
                            Thought I'd add this to the register, for future reference.

                              Maybe something fallen into the spare wheel well?

                              • Weird thing happened to me on friday.
                                i was sitting in my new gti only done 1900km on it, had the radio on as i was waiting for my gf, the car decided to switch itself off while the key was still in it. and everything went blank so i took the key out and restarted the car, and the data in MFD had all gone, it was like the processing unit has restarted itself is that normal? anyone else had that problem??

                                apart from that i love the car and i have to say best car drive around.
