B11B0 71 Wipers Control Mechanics Fault

[Elnes]

Hi,

I have an issue with the windscreen wipers on my Peugeot 508 RXH, 2014.

The right wiper does not extend more than half way up the wind screen. The left wiper apparently works as it should, however diagbox gives fault code B11B0 71 Wiper Control Mechanics Fault on the left wiper. There are no persistent fault codes on the right wiper or the BSI.

Does anyone have experience with the same or similar issues? The logical move would be to replace the left wiper motor, but as they are quite expensive I would like be as sure as I can.

Thanks,
Simon

Thank you, Sir!

I'm afraid it's not much help because it can be either of the motors. They work in a slave / master relationship, so is not always the motor you may think.

Can confirm. I took it apart and it was the right motor, not the left. More precisely, it was the wiper arm linkage that was completely seized.

Do you by any chance know if this can be bought separately?

Hi, no they are not sold separately by Peugeot, only the complete wiper motors are available.

Alright, guess I will give it another go and see if I can bring it back to life.

Many thanks again, really appreciate the help!
