So I need a DME Relay. I'm assuming I can use one off of any 944 and obviously a 924S. I don't know about a early 924 though. I see a bunch on eBay. Do I need a specific year?

 

Can't help you with the exact answer, but the spare DME I keep in the glove compartment has a 993 part number (I have a 968) so it could be that your car will accept DMEs from a number of different Porsches. If you don't get a definite answer on Rennlist, I'd call up a Porsche shop and ask

 

you've got a problem with your DME relay ,one of the most critical parts of the Bosche fuel injection system and you're thinking of buying a used one on ebay ??????

Whats wrong with ordering a new part from your Porsche dealership for $20 ?

 

There's several different DMEs for these cars.

'83 thru '85 944
'85.5 thru '87 944 ('87 924S)
'88 944 ('88 924S)
Not sure about '89 and later...

 

relays are interchangeable between 944/924S. ive used the relay on my early to start a friends 89, and currently am using the relay from an 86.

 

Just had a search at the Paragon Products (no affiliation) web page, here's the list of Porsches that use the same DME relay:

911 89-98 (964/993), 911 Turbo 93-99 (964/993), 924S, 944 all, 968

 

They have new ones on eBay. Which is what I'll be doing.

Thanks guys!

 

soooooooorry I thought you meant used .

I suppose the advantage of buying from Porsche is at least you can be certain of getting the right relay I guess.

To be certain about using substitutes you need to see a schematic of the internal layout of the relays and check the orientation of the spade connectors and the internal connections Its a bit risky tbh

Maybe it would be a good idea to post a sticky of the parts throughout the Porsche range which are compatable with the 944 and also Mercs and BMW parts that will fit etc
