I bought a 78 240d a little over a year ago. It has been getting harder to start and wouldn't start for my wife the other day as it gets colder. Apparently the last owner put the enhancement kit as seen here:
Glow plug enhancement | The sad mechanic exercise
Well, the relay went south. The connection for the wire to the fuse and then plugs burnt up and just spins in the relay body.
Problem is, I can't find this relay anywhere. Anyone know where to find this particular relay?
