W209 CLK coupe parking sensors stopped working?

[moonloops]

There is just no lights on the unit at all. It is a dealer fit system not genuine Parkatronic so not sure which fuses to check etc. It also can't be enabled/disabled via a button so it's not that?

Any ideas or something obvious I can try. Rear system only fitted..

thanks

Think I hav found the culprit. The black wire that runs from the unit and looks like the end of a mobile phone charger or other PSU.. it is hanging loose behind the dash near the fuses.. can't for the life of me see where it is supposed to be plugged in ??

*FIXED*

The power lead was infact from a plumbed in tom tom power supply

"parkatronic" box in boot had a disconnected plug
