    Good point & not the type of consumables I was really thinking/referring to. More brake parts, tyres etc.

    Don't drink beer.

    I love learning, no matter where in the world. So fire away - or not.

    So long story short - Dealers can see the flash of the gearbox parameters using standard tools?

    I can’t see any evidence to suggest anything can be seen by the dealer, so my thoughts are as always..

    Without proof it’s all hearsay :) and something with a keyboard and too much time on their hands

    After removing the Tune Box & Pedal Box, SMI77 @ Audi today for 30K service.
    No mention on the Service Report or by the Service Advisor about the trilogy.

    Talk about the saying, one doesn't miss something until its gone. Driving to the dealer was a real disappointment. They will return, incl. a tranny reboot.

    Courtesy car was an A3 sedan. Just say we were v-e-r-y glad to get ours back.
    Noticed on the A3, above the doors (rears at least) there appeared to be a drain plug in the roof rail. Does the roof in an A3 ship water?

    Be mindful that this is from a distant, but f-a-r, f-a-r better outpost.

    I'm pretty confident the TCU settings are slowly reverting back to the factory parameters after a few weeks on my S4. Car is in for warranty repair on the seemingly common thermostat fault next week. Diagnostics machine didn't flag anything on the transmission side.

    What makes you think that, there is a degree of 'adaptation' to the driving conditions that can take place, thus I would have thought refreshing with the dongle would clear the TCU...

    This is my point, the gear changes become gradually worse over time until they feel the same as before. Repeatingly flashing, idling and bombing around in the car to preserve the effect isn't my idea of fun.

    Can't say I have noticed this myself though, seems the same as it was when I first performed the flash...

    It’s more likely that it’s become the norm and so you don’t notice it any more.

    I have to admit that I think the settings do adapt back closer to stock as the shifts on mine because increasingly harsh at the higher settings of the DTUK box. The altered shift points with the transmission in 'S' mode stayed though and made it nicer to drive when using that setting. A few minutes once a month resetting it did the job no worries.

    Exactly this as the ECU gets fooled into increasing the rail pressure that delivers more fuel than the ECU is aware of .
