Wife reported the drivers side brake bulb wasn't working.....Simple fix....I thought.

Bought two brake bulbs. swapped the duff bulb out put new one in......No light when brake pressed. Faulty bulb I thought, tried the second new bulb...no joy. tried indicators reverse light etc on the bad cluster both worked well.

Tried the new bulb in rear passenger side cluster...worked, took it out replaced with original bulb, hazard lights start ot flash yellow brake warning light comes up on dash....big letter F comes up along from where the service info comes up.

Panic begins!

Thought maybe it's a brake switch problem.....I had a new brake switch I had ordered months ago but didn't fit. So read over Paddi't tutorial on here on how to fit the brake switch, hoping this was the cause of the original drivers brake light problem.

Took the old switch out and replaced the new switch (after a lot of tinkering and swearing ) Started her up and no funny lights appearing on dash... good sign, took her out of park and straight away a message flashes up drivers door open....along with the annoying buzz/whine. Drivers door was closed...went out anyway and checked all doors...all closed properly. Started her again, put her into drive ...same thing, loud warning sound continuosly when ever I select any gear, reverse etc...no drivers door warning though, just the noise.

Hoping someone can give me some ideas on what to check.....No expert here.  2010 RRS TDV6 3.0 Autobiography - Stornoway Grey

CANBUS issue. Highly likely to be damaged wiring - most commonly in the wheel arches and around back near the EPB module.  Visiting from DISCO3.CO.UK

Just got back from a local garage....the guy took a quick look at it for me. Crazy stuff, when he checked the rear brake lights the one that had the original fault was working.....the other that had no problem to start with wasn't working!

The guy cleaned the connections and tried two new bulbs and hey presto everything is working fine.........so far.

As for hazards and door open noise on selecting gear.....gone....don't know why...it just is....Jeez these RRS's have minds of their bloody own!  2010 RRS TDV6 3.0 Autobiography - Stornoway Grey

Let us know if it returns.

Hopefully that's sorted it, though, the hazards are indicative of CANBUS problems, but my thinking now is that it could have been a bad case of noise on the brake wiring which upset the BCM/CJB (Body Control Module A.K.A passenger fusebox) more so than usual. Normally, it's less severe and just causes the normal "HDC fault" etc.  Visiting from DISCO3.CO.UK
