I'm new to BMW ownership and after driving my brothers E36 i thought i'd get one to replace my previous car, i tend to buy cheap cars and keep them going for a few years.
I bought a 1993 E34 530i V8 touring manual, i got it for a bargain price of £500 and was aware of 2 functional faults whilst buying, namely rear shocks as the current ones don't really function at all and, bizzarely, the connector to the MAF had been chopped off by the fan, i'm guessing the only way this happened was someone leaving it unplugged as the cable would have been far too short to catch and they are usually very secure.
Anyway, drove it home 100 miles in limp home mode, combined with the suspension made for an interesting journey i can tell you.....
This is the mess i have to deal with: (cleaned up slightly)
Now, before driving i of course seperated all bare wires and insulated them, however the previous owner had not and of course during the fan chop some wires touched.
I noted some welding of the 2 shorter, fatter wires (no doubt including the 12v supply to the MAF) and melting of the surrounding plastic sheathing.
Thankfully the 2 longer wires, which i presume are the more critical sensor wires do not seem to have made contact with the power wires (although they may have done briefly previously, or touched each other)
My questions are,
-Does anyone know the coresponding wiring between the MAF plug and the wires i have? ( i am currently trying to source a replacement plug from a scrapped BMW, bit of a wild goose chase so far)
-I have no doubt the MAF is fine (the plug must have come off before the chop) but i am concerned that the ECU may have suffered damage from shorting, which wires are the critical ones here, i'm hoping the longer ones are the critical ones and they havn't had 12v down them at any point.
I know that ECU's can survive some abuse, i guess i won't know until i fix the MAF.....i don't have any diagnostic equipment i'm afraid.
Any help is greatly appreciated,
