Weird sound on acceleration

[rockDAhouse]

Hi dieterbohlen (best user name ever btw)

Take it to the dealer and drive around with the head mechanic to demonstrate the sound.
I have done the same as I had all sorts of weird noises (clunck, shutter, pinging). I have over the course of 1 year replaced the waterpump, clutchpack, mechatronik and a new gearbox (all under warranty). The dealer was actually quite keen to get all my problems sorted. I assume its good money for them when they recharge VAG for the warranty work. The car is currently in the shop for a not engaging park brake when in "P", the pinging noise when accelerating and rough idle at startup.

Again, if you need something checked out and fixed the dealer is you best bet. And yes the 7speed is quite noisy when changing gears.

Cheers,
regu

which dealer did you go to? sounds promising

Great thread, finally someone else that share the same problem as me.
I've started to hear this ticking sound at 28k, and got pretty worried, even I have over 3 years on the warrenty.

The ticking sound is only apparing when in 1st or 2nd gear, and just after I press the throttle. The DSG has also started to act funny, and I feel something is wrong with the clutch, or something is loose under the right wheel. There has been no damage to the car whatsoever.
I took it to the dealer, and a technician tried it. He could hear the ticking instantly, and we also noticed a metal sound when driving over bumps.
He could confirm something was wrong, and 30 minutes later he showed me a print from VW (he also said this shouldn't be shown to the public..) with a known problem regards to the ticking sound, and apparently it was caused by the DSG. The error code (fault) was 2026473/2. Anyone have any information abount this fault code? Could a firmware upgrade fix this, or is it a mechanical problem?

The dealer confirmed there was no firmware updates to my car whatsoever. I also found this a bit strange, as it's a 2011 (ordered oct 2010) Scirocco on its first service (30k), so I would expect some upgrades (e.g. Navi, DSG, TCS, etc.).


Hope you can ease my pain and tell me it's a warranty problem, so I don't have to drive around embarrased bacause of this sound. I paied 100k AUS dollars for this (in Norway), so it shouldn't sound like that.

Thanks

Bulletin 2026473/2 is October 2011. So its missing if you have the noises. Reprogramming of the DSG ECU is required to recognise rough roads like cobbled surfaces. Results in quicker gear changes so on rough roads the rattle/clatter is less and no clutch adaption happens . Owners usually confuse this update with the effects of 37G7 campaign, it just gets loaded when 37G7 is done because the latest firmware also has previous updates such as 2026473/2.

There are no warrenty instructions as its regarded as normal. No instructions to update the DSG ECU separately for 2026473/2.

Thanks RW1, if I understand you correct - the smart thing would be to send a request to the shop tomorrow and ask for an DSG ECU upgrade to version 37G7, and hopefully that will fix it. A second workaround is to shut the windows of course..

Yes its one way but as with my October 2009 build, the DSG may not be targetted for 37G7 so it may not be accepted as part of 37G7 worldwide campaign and therefore warranty costed.

I had this rattle on acceleration on my manuals golf gti. Dealer fixed it under warranty. Never asked what the problem was but was advised it was common in the golf mk6's. Ask your dealer, I'm sure they know what's causing it.
As for the shuddering upon acceleration, it could one of your coils are dying. Have it checked and replaced before it gets inevitably worst.
