I have been a member of this and the other 968 forum for a long time and have a basic question. I have noticed that a number of members have suggested that we should keep a spare DME relay on hand as that is the primary cause/cure of basic problems. I have looked in catalogs from all of the suggested vendors (PerfParts, Paragon, Tweeks, etc.) as well as trying to locate it in PET and haven't come up with a source of this item (no, I haven't tried my local Porsche dealer, as that would be too easy). Also, where is this beast located? It's not in the usual spot, unless I've missed it. I had a tip for a while so I know there are relays under the steering column, but this one eludes me. Any suggestions/advice? Or am I being too anal about this? TIA,

The part number for the newer DME relay is 993-615-227. It is in the fuse box under the hood, near the bottom of the windshield on the driver's side, location G5. Cost from Sunset Imports in October 2003 was - hold onto your hats - $12.16. I installed the new one and keep the old one in the trunk - just in case.

If you have a 944.XXX etc part number on your DME relay it is the old type and will almost certainly fail at some point. Replacing that part with the 993.XXX etc. DME relay can indeed cure all sorts of ills (in my case, hot starting problems). The 993 relays are extremely unlikely to fail, but like Anchorman, I keep my old one in the car just in case, too.

My '92 coupe wouldn't start Monday night. It turned over vigorously, but not a pop. I remembered all of the DME chatter from here and 968 Net. In the morning I pulled off the engine vanity cover, cranked the car over for a few seconds, and pulled the No. 1 plug. No gas smell on the plug or from the plug hole. As the DME apparently controls the fuel pump, that was diagnostic. Checked prices and shipping, and ended up driving the 30 miles to Brumos, yeah, that one, and purchased the 993 DEM version. Checked the inside of the fuse box lid, as mentioned earlier here, found the culprit, installed the new one, and the car started right up. I was looking at having it towed AGAIN. Thanks, everyone. I'm getting a spare.

To get things a little more current, at least as price is concerned, I just ordered one from Sunset. 58 bucks! Guess we've had giant inflation on relays.

You can get a genuine Porsche one from numerous aftermarket parts sources so there is no need to go to the dealer and pay twice as much.

It is also possible to make and carry a jumper wire to replace the DME relay if it fails while you are out and about if you do not want a $25 part sitting idle in your glovebox.

If you have the 944 part I suggest getting the 993 one installed and put the 944 part in the glovebox but if you have the 993 part I would not worry too much about it, maybe make the jumper wire and carry that.

DME diags and jumper wire info here:

Executive Summary:
"If you suspect the DME relay is bad and you need to move the car, you may install do so by installing an "emergency" jumper across terminals 30, 87, and 87b"
