Another dead DSG, ...or maybe not?

VW already have that, I had a brand new 130TDI Passat loan car last time my car was being serviced, it had free wheeling on overrun.

So I take it that manually freewheeling in the Yeti is perfectly ok?

Not sure.

VW have designed this particular version of the DQ250 DSG to operate in this way. I have no idea what the differences are between this design and previous designs. It would be quite a leap to assume the fact that a later version has been designed to operate this way clears the way to operate an earlier version in the manner you have described.

I think if you accidentally knocked it into neutral and the re selected D and it damaged the box I'd be pretty p..... and want an explanation why N wasn't protected by lockout.

If you give it a go i'll be interested to hear how you get on.
I would try it at about 70kph in 6th the first time, so there isn't a big difference in the rpm needed to get back into drive again. Just in case.

So would I, doesn't mean I'm going to assume that it is OK to do so, potentially an expensive way to find out if it is OK or not.

Curious to understand your comments about not wanting to wear out the clutches. In all the years I've been on this forum I don't recall seeing a single post relating to premature wear of clutches on a DQ250, for that matter, I can't recall a single post about replacing DQ250 clutches other than a handful where users were doing engine mods and were upgrading to cope with significant increase in power output.

No No, you go first))
My theory is that the clutch that handles 2/4/6 doesn't engage until the road speed sensor matches the main shaft speed by application of the precise amount of fuel to the engine. Seeing there is no big deal with everything being digitally driven and monitored.
I guess as each through SAE articles will be the best way to research it.
A theory of mine is if Toyota use it, it must be bullet proof.
They don't!

Re clutch wear, I'm meaning the moving off/and 'drag' against the handbrake when in D. Also idling on an upslope sufficient to not need foot or handbrake (I'd like to know what's going on there in particular because it's not that uncommon in a conventional auto).

Thanks but i'll pass.

I think it would work or lock you out. The danger is that it works but over time causes problems.
I like the idea of the DSG software being modified to alter shift patterns, remove the torque limiter and increase the clutch pressure to lift the capability of the box.
I read somewhere that VW will upgrade the software on the DSG, for free, to match the latest spec which improves the operation and the life.

My Toyota 86 manual was a Subaru with some Toyota parts. Lexus gearbox, LSD and direct injection are the main Toyota contributions. After about 12,000km the 5th gear synchro failed and they fitted a new gearbox. They were good in replacing it quickly with no hesitation but it was far from bullet proof.

if any one needs info on this silly box that volkswagon have and having problems let me know.i rebuild them for a living so forth.

Is there anything we should avoid doing and is the DQ250 more reliable than the 7 speed dry clutch version?
