My R32 tyres spin in Park...

[gerhard]

I vaguely recall a similar symptom in my Honda bikes years ago. Sometimes the clutches would grab a little when starting the engine, and "snatch" the chain a bit. Maybe there's a similarity in the behaviour of the wet clutches.

I'd probably be inclined to change the DSG oil. A bit expensive for something that may not fix the problem, but maybe you could suggest this to the dealer and they might agree to do it at no charge.

The car has only done 9000kms.....not too many have experienced this issue, and those that have, agree that it is irregular, and very difficult to replicate. I cannot see how changing the oil could be linked to this.

And even money that the dealership would say the same thing.

I cannot see how changing the oil could be linked to this.

Changing the oil in my daughter's Swift gearbox last weekend caused the slight snatchiness into second gear to disappear.

Changing the oil in automatic transmissions improves the operation of the solenoids, the smooth slipp of the plates, the operation of the pump, and the torque convertor operation.

Changing the oil in a LSD removes the shuddering of the clutches which happens to LSDs.

It's not a difficult concept to grasp that new oil with its fresh lot of additives and conditioners will improve operation of DSG clutches too.

If you cannot see how new oil would improve things, I guess you would fail to see how changing your engine oil is beneficial either.

Don't forget gerhard....you only said

Maybe there's a similarity in the behaviour of the wet clutches.

So...your theory to which I responded to, was based on a 'sorta kinda maybe/maybe not" gut feeling.

I was touting that maybe there isn't a similarity. Neither of us know for sure.

Don't fall from your lofty position.

At least I offered a suggestion that might resolve the OP's problem, which is more than you did. You cannot see how an oil change could help; I can.

If that makes my position lofty, so be it.

I merely said "maybe there's a similarity in the wet clutches" because I have never seen the DSG clutches disassmbled. But for your benefit, I'll say this - there is definitely a similarity between all wet clutches. Therefore the DSG clutch could be "sticky" due to substandard oil, just like a LSD clutch or a motorbike clutch can get sticky when the oil is past its use by date.

With a bit of luck you might suggest something else that might help the OP, from your self-confessed less lofty position.

I'm reaching 'desperate' pretty quick here, so I'll try anything. Will give that neutral - park, handbrake, brake one a go - but I thought that brake ON meant the DSG was disengaged? Am I wrong?
I will even suggest the oil thing to the dealer and see what they say.
But I will also be writing to head office voicing my disappointment with a brand new vehicle that has a fault which nobody at the dealer seems to be concerned about - which is a real safety concern.

Settle, boys ! There's absolutely no need for an e-penis size argument here when we should be trying to help the OP with his very real problem.

..... I'll say this - there is definitely a similarity between all wet clutches. Therefore the DSG clutch could be "sticky" due to substandard oil, just like a LSD clutch or a motorbike clutch can get sticky when the oil is past its use by date.

I'll agree with this, having experienced a sticky wet clutch on several different bikes. And I experimented with lots of different oils until I found one that suited each particular bike.

However, regardless of the performance of the clutch (ie sticky or not) I would have thought that the DSG should be in neutral (on both shafts) before the engine would be permitted to start.

So by my understanding of the OP's symptoms, that means a sticky clutch could only cause this issue if the gear was also engaged BEFORE the engine actually started. As the OP hasn't reported symptoms of a sticky clutch at any other time, I'm personally discounting a sticky clutch as the cause of the problem.

That leads me to think that a controller problem is more likely - possibly the infamous mechatronic that is frequently being reported as faulty and being replaced by VW.

Anyone got any better ideas and/or see a problem with my logic ?

Maybe if you could take a VCDS (Vag-com) log of the status of the DSG gear selections and clutch actuations at the time of start-up it would show up an anomaly (eg 1st gear selected and clutch partially engaged before engine start) ?

I think a member on here (userid "logger") has been doing some logging of very detailed gearbox info on his Mk 6 DSG (7 speed dry clutches). He may be able to offer some useful advice on what to log and how to interpret it.

Of course if it only plays up once every 1,000Km or so it may be very difficult to catch

Have you tried talking to the dealer principal at the dealer that sold you the car ? Sometimes thay aren't aware of exactly what their employees are doing and will instruct the employee/s to be a bit more responsive to your plaint in future. It's certainly worth a try (and will probably give you a better result than what you'll get from VW Oz head office).

[silver32]

Thanks for that suggestion - I will try and make contact with the guy who is logging his own DSG and see if I can get some help from him. I will also contact the dealer principal ASAP. I hope I get somewhere with this as I would hate for this to contribute to a (very costly) failure once out of warranty, as I heard someone on here say a new DSG cost $18k to replace!
For now, I havn't had the chance to drive the R for the last 4 days, but once I get back into it I will try and record every start for now, at least if I catch it once it will be some proof to help my case.
