2.0 TFSI Quattro (8P) Sportback. AWD stropped working at same time reversing senso

[TonyH50]

2.0 TFSI AWD stopped working, No ECL, and rear parking sensors stopped working too
Noticed AWD not working, too much wheelspin and traction control light flashing. See VAG-COM extract below. Then noticed rear parking sensors not working giving a continuous tone when selecting reverse. Reckon loose electrical connection so drove over some speed bumps. Problem went away. Sensors and AWD now working.

Any suggestions where a common connector for reversing sensors and supply to Haldex clutch might be?
