Multiple warning lights MIL, ABS, ESC, Parking brake, etc

[Tugg]

Just wanted to post my issue and more importantly the solution. Started car to commute to work only to find the dash was lit up like a Christmas tree! Drove to work fine, despite the warning lights (none were dangerous), but noted front and rear parking sensor, cruise control, stop/start no longer worked.  On finishing work started car to find all warnings had cleared and so drove home perplexed but relieved that car was fully functional again, however on arrival (30 mins) I decided to stop and then try restarting which resulted in all the warnings returning 🤦🏻‍♂️ and remained present for weeks. The codes were; Engine fuel limitation U111300, Steering assistance U111300, Parking brake U111300, Electronic parking brake J540 (00473), Brake control module 01316, Right Rear ABS sensor 00287. However nothing regards parking sensors or Stop/start.

Tried a few things over the following weeks however finally discovered all caused by the defective right rear ABS sensor, which had imploded in the hub due to corrosion in the ABS pocket, resulting in having to drill the old sensor out! For info Audi sensor £150 but went for a £10 part from Spares Hut, obviously OEM is best but some times I draw the line at these crazy inflated prices.
