I have recently bought an Astra 1.7cdti (05 plate) with 53k on. A week ago the battery light came on. I got it booked into a garage the next day but on the way the car just died. All the dash lights, hazards, central locking etc still worked but there was nothing when I turned the key. I got it recovered to the garage and they tested it and replaced the alternator and put a new battery on. The car worked fine for about 20 miles then the window blowers began to cut out every 10 seconds or so. After another 3 miles the ABS light, batter light, engine management light etc all came on and my rev counter and MPH counter died. I also lost power steering and my lights failed. Luckily I was on my street when this happended so it made it home. Now it will not start again. There is just nothing on the turn of the key.
Any ideas people?
