Reversing light defective

[Bobbo2]

Hi all,

Had an error message come up recently: "left reversing light defective". Car has LED lights so can't replace bulb. Assumed a new sealed unit is needed. Took a chance on a used unit from eBay. Replaced unit but getting same error message. So either I bought a faulty unit with same problem, or it's an issue that's due to something other than the light unit. Any ideas? Anyone had the same issue? Trying to avoid the inevitably expensive trip to the dealer.

Cheers

In case it helps anyone, I managed to sort this myself. Swapped the light units and still had the error message when the working right side unit was connected to the left.

Assumed it was therefore a wiring problem so took off the boot hinge trim and went searching. Quickly found a broken wire at a bent bit of the wiring loom. Fixed the wire and made sure the wiring loom was properly reseated in the trim. 20 minute job and I'm very much a novice.

funny enough just recently and typical my m.o.t was due for renewal and i got a warning on the dash to say my rear left reverse light had failed.i thought it was a bulb(none led) so i replaced it,but still no joy.so i fiddled with the connector and it came on.their maybe a slight fault with my wiring will just see how it goes.oh and yes now 12 months m.o.t

Same, my MOT was due about a month after the fault occurred.

From what I read, it's a bit of a design issue with saloons because of where the wiring loom runs through the boot hinge meaning it's prone to getting pinched when the boot is closed. 

 

Have a look in the compartment in the left side of the boot. Could see my wiring loom hanging loose in there and I think that's why the wires were getting pinched by the hinge.

Reversing light wire is the blue/black one by the way.
