I'm just wondering if this really is fault with the car. With the E46 smg in auto mode on A1 would take forever to change gears so you used A5 - is the lag still there in D5? I've driven over half a dozen DCT cars and not felt this lag. (BTW not saying there isn't a lag just wondering if the other modes cure it?)

I guess the 09-03 means march this year?

PUMA is a UK thing as well, my dealer has already quoted me this. My car is going in next Friday for ignored down shift request and lag issue. I have printed all the stuff out and called service to advise about SIB and roundtable. I will be asking for latest software for ISTA/P. Also, the SIB does say that this software 'significantly improves the throttle response' and 'in order to completely eliminate the delay sensation, as described above, the customer needs to operate the M dct in the manual mode'

The software is also available under warranty according to the SIB.
