It broke down again shortly after, got it recovered to Rentech, the legend, he replaced the plug which goes into the alternator as that had seen better days. But ir broke down again, so the issue must be something else.
Detailed description if anyone can be bothered to read and help, thank you!
''Ok so I got onto the motorway, nothing seemed off, as soon as I hit 75mph, the speedo pin just dropped and it flashed at me saying airbag fault, abs fault and brake fault. So I moved onto the hard shoulder (my brakes worked perfectly fine, my indicators were working. Nothing was wrong physically with the car)
I left it for abit, turned it on and there were no warning lights and everything seemed normal so I tried to get it off the motorway. Again, I hit 65/70mph and the same thing happened again. AA comes, say they think it's an electrical fault and follows me to Winchester (was doing no more than 55/60mph) he left as it seemed to be working fine again. I drive around for 15 minutes down small roads (20/30mph) and I think I can see smoke, look at the temp gauge and it has gone completely off the meter and the cars telling me to stop. AA come and move around my alternator cable as he thinks because another mechanic cable tied it away, he's done it too tight so there's not enough power supply so the cars shutting down.
Drive Winchester to Portsmouth down back road (most I done was 50mph) worked fine. Got onto the motorway the next day, hit 70 and the problem happened again. AA do a computer check on it, can't find anything wrong with it.
I drive to Crawley doing no more than 60, was fine. Drove it around yesterday, no more than 50, was fine. Drove it last night, hit 70 and happened again.. This time adding more faults (something to do with the battery, the power steering went, the car lost power, the dashboard wasn't lit up anymore but the car lights were still on thankfully. Haven't touched it today.''
