HELLO FROM ' NEW MEMBER ' , REFS : 2012 A6 Avant / ' S-Line ' 3.0 TDI / Reg No - FIB 730 Bit of a long winded story but best you have ' Chapter & Verse ' . This is my 3rd Audi , the two previous ones ( A8 & an S8 ) were both essentially bullet- proof & completely reliable save for a tiny number of very minor issue's . MY GEAR BOX PROBLEM :- This problem first cropped up 5 - 6 x months back when a small ' Red Triangle ' followed by the message ' " Gear Box Malfunction - You Can Continue Driving - ( Limited Functionality ) " came up & you'd have difficulty getting Reverse & also getting , Drive ( & when you did almost always went to D1 & then D2 and would go but wouldn't change up further than 2nd ) I don't use the car much but quickly found that if I turned the engine ' Off ' and then back ' On ' again and quickly selected ' Reverse ' or ' Drive ' ( seemingly before the car's computer's had the time to wake up ..?? ) - that I could then use the car quite normally & the gear box would work perfectly as usual . I was on the point of booking the car into my local villager garage for a " Look See " when up came the messages ' Coolant Level Low ' & ' Washer liquid low ' - so I therefore topped these up straight away as bid etc ... ' BUT ' the very strange thing about this was that whilst seemingly completely un-related , the ' Red Triangle ' & the ' Warning Message ' disappeared completely after this & the car functioned completely normally ( gearbox included ) for the next 5 - 6 x months until last week when they came back - I did the same as I had previously to try & effect the same ' Cure ' - but no such luck & again sometimes will not select ' Reverse ' & in ' Drive ' & will not change up further than - D2 . I've since taken the car into my local village garage & he had his regular ' Techno / Electrics Man ' go over it & he pulled up 2 x Fault Codes relating to the gear box - which he cleared . They told me to come & get the car & if the triangle & warning message ( & the problem clearly ) re-occurred - to bring the car back . ' BUT ' Within 2 x miles & 20 x minutes - it had all come back & so I was back to ' Square One ' . The ' Fault Codes Were - P174 D00 & P173 F00 which they said related to - ' Valve Chest ' & / or - ' Wiring Faults ' , but to move forward you'd need to know which specific gearbox is fitted to this car as Audi had fitted 3 - 4 x different boxes to the ' A6 ' . My village garage is very good but very small & they've said that they aren't really equipped to go any further with this type of gearbox & if I wanted them to continue . then they'd essentially have to farm the job on to someone else . I don't very much like this idea - hence this note asking for advice & guidance from other Audi owners who may have experienced the same issues as me ...etc...etc . Any help from anyone - anywhere will be much appreciated . My E.Mail is - [email protected] - so please get in touch if you can wise me up & point me in the right direction . Many Thanks / SIMON .
