DSG woes in The Age

DSG : Volkswagen UK

Link above is for official VW UK literature of DSG...now where does it say that you have to drive it unlike an automatic???

Well it does say "it's totally unlike a conventional automatic transmission", which is not quite the same thing. But it doesn't claim anywhere that you can drive it like a conventional automatic either

Did you see the headline though?

"DSG - Ease of an automatic with the responsiveness of a manual"

Well no point getting my car repaired then, as new Mechatronics unit clearly wont fix this overheating.
On the other hand If I my car currently has a Mechatronics unit prone to corrosion & shorts due to elements reacting adversely with one another and a new model prevents this corrosion then I reckon I'll get mine replaced.

I don't think an oil cooler for the litre of Mechatronics oil has much to do with the corrosion & shorts. It is seemingly more an issue of incompatible materials. Change the materials to prevent the electrolysis & or widen the circuit paths while you are at it. Remove the potential for shorts circuits. Then this particular problem will be fixed - hopefully.

The new mechatronics unit will not solve the overheating. The only thing that will solve this is modifying your driving style. That is, you need to avoid a situation where the clutch slips excessively by not creeping or crawling. Like it or not, that is what it is about the DSG.

An oil cooler will help because the oil is able to react with the mechatronics unit when the oil gets excessively hot thereby causing particles of the metal housing to come free and short the circuit board. It is not an issue until the oil overheats.

Now if VW are silly enough to replace the existing unit that has problems with a unit that is exactly the same, then the problem will arise in the future and they will have to go through the same thing all over again.

It doesn't say it because marketing do not want to. They want it to be an alternative to a TCG which it is not. If they said it could not be driven like an automatic, then their market share will drop considerably.

In D mode from stopped it has the responsivess (and sound/vibration) of a massey ferguson tractor, but yes it does have the ease of an automatic since technically you dont have to touch anything. Except adjust your nappy after crapping yourself as the traffic bears down on you bogged down in 2nd gear.

I wont be modifying my driving style Thankyou. Never had any problems with my DSG. All I have done is to reset the clutches adaptation with VCDS from time to time.

...It is not an issue until the oil overheats.

How do you now that? Effectively you are saying there is zero chance of the electrolysis occurring, leading to possible short circuits, provided an overheat never occurs. Big call. I will go with the new part number. You change your driving style and to prevent the overheating and lets see who's unit lasts longer shall we.

Now if VW are silly enough to replace the existing unit that has problems with a unit that is exactly the same..

Get of the grass. Who is suggesting that?

That's certainly what it sounds like from this article shared in one of the other threads about the recall in Singapore:
The story behind VW's DQ200 voluntary recall

Sulphur in the gear oil and an inorganic heat stabiliser in the plastic parts (iodine) of the mechatronic unit can cause metallic surfaces to be attacked and to suffer from electrolytic corrosion, in connection with high air humidity and high outside temperatures. Conducting particles can then settle between the circuit paths of the control unit and could cause a short circuit.

No problem. If you have no problems, then you have nothing to worry about.

That is what has been reported. Hey, you don't have to change anything.

Correct, No Problems, Not worried. Will be reassuring to have a new Mechatronics unit fitted. The chance of a future corrosion issue leading to a short and an expensive repair will be removed. All good.

Thanks for posting the quote from the Singapore article. Note that it does not mention "oil overheating" as a prerequisite for the electrolysis, nor that an oil cooler would effect the issue. You are speculating about that. Thanks for clarifying that.
