I thought they replaced the covers no matter what?

I had the service manager for Nottingham on the phone and he said he would be ordering in all the parts so they wouldn't have to wait no matter what needed doing, it all depends on the competence of the people dealing with it. Get the eye candy on the service counter and you stand no chance as they know nothing.

Bypass the tank for now, it will work slower but should get you going if it is that, other thing is to try and pull a vacuum on the tank and check you can blow through it.

If you have blown a unit this bridges the optical link to restore audio.

Looking at your PM chance is you just blew out a fuse or 2 so start with that m8.

Have you tried MOST loops to diagnose it? I always carry one just in case. https://www.ebay.co.uk/itm/2PCS-MOST-Fiber-Optic-Loop-Cable-Plug-Connector-Fits-Audi-BMW-Mercedes-Porsche/352700499048

The pipe from the vacuum pump should be disconnected and plugged, nothing needs to be on the valve apart from the electrics. Sent from my SM-G920F using Tapatalk

Yep used it myself ended up soldering that bloody centre pin, what an absolute pig to do

TBH I doubt I would buy BMW with the intention of using the warranty side as I have had nothing but shocking support at every step.

What ones your guide m8? I saved everything I could find on it as you know what the internets like for dead links!

Yes and use genuine, if it still does it and you drive an auto it's going to need the inline mod for the gearbox cooler. Sent from my SM-G920F using Tapatalk

Did you expose the wires or just look at the wrapped section? https://1drv.ms/f/s!ArTAP9qwiGB0iuxqCmlB-Xlb20OAWQ Sent from my SM-G920F using Tapatalk

The AHM (trailer) modules the one that gets coded, the light module and another one or 2 flagged up when I looked in ISTA-P but it only had the retrofit for the swiveling head so it moaned it wasn't there. In the end I added the right code to the VO in NCS and did the defaut code the LM (that also tells the CAS) and that took under a minute m8. http://codinge90.com/ncs-expert-how-to-modify-vo-vehicle-order/

The E60 can't detect LED faults, it's obvious when you look at the LM config for LCI where the checks on the rear indicators are turned off. This is part of the config file that you can tinker with, or let ISTA-P do it
