Is your DSG dying? Or is it just the Dual Mass Flywheel?
hi guys, how are youse?
i've searched here but couldnt find anything really, but forgive me if this is a double-post. im sure peeps in here would know this, but i didnt, and i reckon the info might hopefully help people with DSG's who are fearful of replacement costs.
so i was searching the internet for info on whether or no you have to "bed in" a newly installed clutch, before giving it the beans... and of course, it dawned on me to check tdiclub.
now, i've been reading a VERY interesting thread regarding people with DSG tdi's with more than 60,000 miles or so, who are getting the symptoms of a dying DSG:
- grinding at idle
- rattling noise from transmission area at idle
- vibration when in gear, park, whilst driving
- vibration during shut down
- etc...
i for one always took it for granted that the DSG was some fancy thing with two fancy unconventional clutches, not really knowing how it worked, and that if the above symptoms started to show up you had no choice but to replace the whole thing, at $10,000 or whatever.
a tdiclub member took his car, with the above noises, to a dealership, and was informed by the VW dealer service manager, service advisor, and senior tech that the sounds from the transmission were ''within tolerance'', ''normal and will not affect the car", and that diagnostic scans had returned a clean bill of health.
he was also told explicitly by the people above that the DSG does NOT have a dual mass flywheel, but rather "just a flywheel", attributing the sounds to clogged fuel filter, or perhaps fuel pump.
later, a mechanic in the dealership took the box apart to find this:
now, the rest of the thread is quite long, but from what i can gather, people have been identifying these sounds/ aural symptoms as they start occurring more often, and have been able to rectify the issue not by parting with ten grand, but rather replacing what are evidently failed dual mass flywheels that are in the DSG box itself.
the costs seem SIGNIFICANTLY lower than a whole new DSG box, as what is involved now is a replacement DSG dmf (updated/newer part numbers are listed in the thread) and around 10 hours labor to change the failed dmf out - in fact, b1llyb0y from this forum posted $1600 for the dmf plus labor.
i'll let you guys get into the thread here.
posts that came in particularly useful to me, so far, are:
#1 (obviously), 5, 20, 57, 108...
enjoy!
p.s. i posted this here as i found the info on tdiclub, but if this info is applicable to others, perhaps this thread title could be listed in other sections? it seems like many of the models have had some sort of DSG issue, be they polos, golfs, tiguans etc, and it would be rad if more people in the community knew about this, rather than take it for granted that they're going to have to pay large for a new gearbox.

) you should hear a "can of marbles" rattling type sound for a while... That's the best way to tell you have a dead DMF... All it is is that the spring in the DMF wears out/breaks and rattles like nothing else... But generally only makes itself really known on a cold start on a cold morning.
