I recently (thought I) fixed my pulsing rear lights and stopped the Alfa control warning lights coming on by making an earth wire and soldering to the strip of metal in the light bulb clusters and bolting said wire to the inside of the boot. They kept coming in whenever I hit the brake pedal. Now, it's randomly started doing it again! Every time I hit the brake pedal the main rectangular warning light comes on with the 'stop' and brake pad wear warning lights! All brakes are perfect and the new earth leads still intact! It had been working perfectly. The rear lights aren't pulsing so it's really bizarre and out of the blue. I'm kind of out of ideas on what to check next. Poxy car. Just had a new radiator and now this! One thing after another in my strive for perfection!
