Reverse Sensor Intermittent Problem

[tezerez]

Hi, First question to this excellent forum.

The reverse sensors on my 53 reg TDI130 have started playing up!

Thanks for that, have got a lead on order.

Will have to do research on forum to see what to look for.

Me Again, Anyone any ideas what to look for on vag-com (actually vcds lite) to find out which bit is faulty?

Does it let you know either ecu or sensors ?

Thanks in anticipation.

Hooked up to vcds-lite (after a few false starts) and it not only showed fault, but which sensor causing prob!

Back to fleabay for new sensor, then hopefully back to safer reversing.

Thanks for help.
