Sudden Electrical Issues

[Mats]

Hi guys,

I hope you can help me.
This morning my car worked just fine. On my way back I wanted to change my electrical seat. The seat adjustment suddently stopped and afterwards (maybe it was there before and I didn't realise it? Cannot guarantee it.) I realised that I neither have an indicator sound nor a symbol on the dash. The AC shows "ER" and the central locking does not work.

Do you have any help in your limitless wisdom?


Cheers

Yep, send marinabrian a pm, sounds like you could have a wet ecu!

Is your boot dry Mats? if not perhaps the sat nav is wet

K-bus faults, check to see if your front windows are reversed, and if so you need to pop along to see me

First things first: Brian, you are an absolute star! Thanks for all your dedication and help!

For everbody else with similar issues:



After testing/swaping several ECUs, the problem for all those electrical issues turned out to be a completely demolished cable from the electronic seat which was caught by the seat itself. It "simply" needed soldering. Easier said than done when the seat is lowered to its minimum and not adjustable anymore.

BTW: It's not very typical to happen... only when a certain Rover owner assembles the seat respectively lays the loom incorrectly...

And for anyone wondering, the K-Bus wire to the drivers memory seat was the casualty, causing mayhem as it shorted to +VE and seriously upsetting the EWS3 or as Mats would have phrased it "elektronische Wegfahrsperre" and LSM, which stymied T4 at the first hurdle

Happy Birthday Mats. I hope the rest of your weekend is fault free
