DME Relay Questions
 
Have a few DME relay questions below. My 1993 911 (964) has a reocurring problem of a failing DM relay. The car will run fine for a few months and then start to skip. After replacing the DME relay this takes care of the problem but I'm going through around 2 relays a year. A few question below.

1. Is it normal for this relay to only last about six months?
2. Is there one brand better than another. I usually buy from our host pelican.
3. Can these be repaired ( I have a small collection of these relays now)
4. Is something else in the system causing this relay to fail?

On the 3.2 relays, repairing is usualy just reflowing the solder connections. They seem to be manufactured poorly and the solder connections fail.

are you using one from the dealer or an off-brand?

Have you considered opening the relay to see what component is actually failing?
