Tailgate wiring break . 330 touring. 2006

[G Rawlins]

Can anybody recommend a wiring harness repairer/ installer in the Essex/ east London area that is competent to do the SENCOM harness replacement?

My local dealer wants over £100 just to give me an estimate. I am unable to open the tailgate again and can see the broken wires in the harness. I  did a temporary repair last year and it has broken again. theres a vicious bend in the harness (there since new I assume) . I've seen this fault mentioned in a few forums, and the SENCOM repair is mentioned but I'm not sufficiently competent to do the job.

Hi G

Welcome to the Forum

I have read a lot about this issue over the years not just a BMW problem by the way several Marques have issues as they use PVC insulated cables which become brittle in low temperatures, couple this with everything being as short and tight as possible and broken cables are inevitable.

There are repair kits available but if buying one make sure you get a silicon insulated one with multi-cored cable for flexibility and sufficient length. As for carrying out the repair it is within the scope of most competent home mechanics, and certainly easy for an Auto Electrician or good Independent Garage.

Good Luck
