New to the site but not new to car forums (I'm all over the Honda forums etc...)
I've had a good look round these forums and searched but couldn't really find the answers I'm after so here goes
My brother has a 318 S reg auto saloon; recently the electrics started playing up stating that he had a bulb out when none were out and now the brake lights stay on (inc 3rd brake light) even when the car is off/key out of ignition etc...
He's had it to the Vehicle Maintenance Unit (VMU) at Lancashire Constabulary and they have said that its the 'General Module' that's failed.
I've found a few for sale on eBay but wanted to know is do they need to be plugged into a diagnostics machine to get them to work correctly OR are they simply plug & play? This is the module I'm looking at: eBay - The UK's Online Marketplace
Any/all advice is appreciated
