HI keyla
check the DME (DEE) relay under the seat

the 2nd fault in on the test plan is the DME (DEE) relay if the earth's are OK

good luck.

Consider carrying a spare relay.

I just replaced mine, as a precaution, on my 911. The aftermarket part number is 3.308.100 made by K.A.E. in Berlin, as supplied by our host at a very reasonable cost.

The original Bosch part had the time date imprint 24, 06, 85 and the manufacture date of my car is 7-85. Of course it had "made in W Germany" on the relay.

I wonder if the new part would have a service life of 23 years too?
