B5 s4 ttv flywheel vibration9/7/2023 ![]() ![]() I had exactly the same problem before the new cambelt kit was fitted, after it was fitted the idle was fine but after about 6 weeks the rough intermittant idle came back.Īfter ALOT of searching this VERY common vag diesel problem i deceided to alter the timing on the cam sprocket as detailed above but without the use of vcds as i dont have it or could get the use of it.Īnyway, i turned the cam sprocket clockwise about 1mm then tightened the 3 nuts back up and tried it, the idle was better but still not as smooth as i wanted so i turned it clockwise about another 2mm and now the car idles/starts/drives perfectly. JUST to add this is my GF's car so i' kinda doing this for her so i dont drive it daily too see how it acts BUT i do drive it once a week and have tried things like injector cleaner in the fuel to sort it but has made it slightly better but not fixed by no means.Īre the pd injectors all the same? or can the nozzles be changed? perhaps that could be a option? I have a 2001 A3 tdi and i have changed the nozzles on that one no problem but just unsure if the PD injectors can be done in the same way!? if so we could change them upto a higher flow to improve the power before we remap it. and i also think the engine mounts are a bit crap too and need replacing but it is not this causing the wobbles my mechanic suggest there is a miss on it. I know people suggest the loom but i REALLY don't think it is that. but the way it looked was the loom had to be removed backwards ie would need the head off for removal!? When I was test driving B6/7's I did find that almost 100% of them had a vibration around 2K so I am thinking that it is "normal".The injector loom is a **** to change tho is it not!? we had the rocker cover off and checked the loom, cleaned it and refitted and was still the same. Anyhow there are times that at exactly 2K RPM (+/- 50 RPM) that I get a slight vibration but there are also times that I get no vibration.very weird. The PO had the clutch replaced at 53K (couple thousand miles before we purchased it) and I know the FW was replaced but I am not sure if they upgraded to the B7 DMFW or stuck with the B6 DMFW. It went up and down with the throttle both in gear at speed and in neutral.'04 S4 here and I experience the same thing. Tires need to be replaced but it was not an out of balance shake. Guys at the shop said that if it really was the flywheel then it would be a consistant shake and not intermittnet. It happened once on the track too but went away after cool down. But by the time I got it to the shop the problem had gone away. Is is possible to hav intermitent flywheel failure? I had what I would swear was a flywheel problem the other day. If you have any questions feel free to give us a call! Those are just a few of the reason why upgrading to our JHM Lightweight Flywheel and Clutch Combo can benefit you. 3) Stage 3 and 4 Clutch Discs are very streetable and do not compromise daily driveability, and 4) If you are not tracking or beating on your car, this setup will outlast an OEM setup. ![]() 2) Does not feature a failure prone dual-mass setup. 1) Our Lightweight Flywheel costs less than OEM. ![]() We still recommend going with our Lightweight Flywheel and Clutch Combo for a few reasons. I know most people recommend the JHM Stage 3/4 kit with LWFW but I do not plan on tracking the car or anything like that nor do I want the chatter and wanted to gain peoples thoughts on a OEM b7 flywheel and a stage 3/4 clutch kit.Īlso, since I know many people have done the upgrade, would any B7 owners happen to have a OEM B7 Flywheel kicking around?therealet23. ![]() Sometimes the vibration lessens after a spirited run (but it always comes back). No CELs, car runs and has power though it just vibrates (what could be perceived as a misfire) from the drivetrain and through out the RPMs whether in neutral or driving. My 2004 S4 (85k) has what I believe is the dreaded flywheel failure. I am new to the b6 s4 world (though I did have 2 b5's in the past). ![]()
