I have a 2003 Galaxy (diesel 1.9 tdi). Last winter auxillary heater stopped working totally after intermittent firing up with clouds of black smoke, have had glow plug checked and fan checked by local garage and they seemed to be fine. Any other suggestions that may stop the thing working altogether would be appreciated. Also air con got warm this summer, pressure tested, recharged x 3 and still can't find the leak as it disappears over 3-4 weeks - any suggestions. Yesterday the brake light dashboard light bulb indicator stayed on, indicating I had a bulb out somewhere, after investigations to my horror I found all my brake lights were not working. Fuses checked, but no problem found - any ideas? Also glow plug light on dashboard started flashing, and a message saying "engine workshop", yet car starts and runs fine. Unfortunately now also found out this morning that the central locking no longer works, and interior lights have now also failed - any ideas or suggestions other than maybe it is time to change the car would be appreciated!
