I have a 1997 BMW E36 316i with ignition problems. An indie mechanic told me my transmitter receiver relay was faulty and needed to buy a new one and when I took a sample to the dealer I was told to replace the whole ignition unit at a cost of around R5500. I want to find out if its possible to harvest the relay from another car and use it on my car (possibly along with the donor car's keys and ECU if necessary. Thanks in advance.
