Hi All, Sorry my first comment on here is a negative one but I really need your help with issues with my Audi A7. I have owned it for a month and it is a Audi A7 TDi 2011. While driving on the motorway on a dry day, I have had a load of warning signals come up on my dashboard. The warning signals are as follows; ABS, TPMS failure, ESP, Auto/Start Stop disabled, vehicle parked too steep. The thing is, the car drives as it should apart from the start stop technology, handbrake works ok but the computer says it doesn't. I've tried a few searches which state it could be the ABS sensors that need cleaning or replacing? I have had a print out of the warning codes from the AA which are as follows; U111300 U101700 U111100 U112300 U107700 Please help as I am thinking mu already expensive purchase might cost even more :( Im based in Luton should anyone know a good mechanic. Thanks in advance

Hello people, my first post so be gentle with me. I have had my A3 1.9 tdi e sport for around 8 months, fault free. It 09 plate and has suddenly developed a rather annoying fault. On the dashboard there is a red brake warning light (marked in the pic below) that normally goes out when you take off the handbrake, but it now does not go out, and as I start to drive i get a message on the clocks saying "warning hand brake applied" along with a constant tone. At the same time this started happening, my auto door lock is also randomly unlocking and locking the doors while driving, and unlocking them when I stop. Things I have checked. Two different mechanics whom I know well have plugged into it and the only fault code is an intermittent fault 00470 Databus for comfort system; open circuit. They both say the same thing, that this is something often picked up in healthy cars being intermittent. I have spent an hour taking out the centre console to check the handbrake switch and checked their is voltage to the switch and back to earth. I have checked out the brake fluid reservoir levels, level sensor and again power to and earth from it. Brake pads have well over 50 - 60% on them (visual check). Wiring in between the doors and a-posts, all good with no signs of ware or breakage. The car has no other symptoms and showed no signed of anything being wrong up until a few days ago when the above mentioned started happening. Any help with ideas of what else I can check myself before I take it to a specialist would be gratefully accepted. Thanks in advance.
