In the early 2000's, helpful Rennlister's posted that 993 drivers needed to purchase a spare DME Relay to keep in their glovebox in case of the part's failure -- which would prevent the engine from starting. I bought one and put it in my glovebox.
Well, last month I was parked on a Friday evening, away from home, and for the only time in my Porsche 993 ownership (purchased in 1999) the car would not start: turning the ignition turned over the motor but it would not run. So, I remembered the long-stored DME Relay, opened the hood and easily removed the old relay and replaced it with the new.
And, yes(!) the car started and all was fine--no need to be towed and all the stress that goes with it when you are away from home.
As a bonus, my wife was with me and I looked pretty cool to her!
P.S. I've ordered a new one to store in my glovebox for use (perhaps) within another 20 years of ownership!
Here's the part:
Congratulations!
I recently ordered one from Pelican Parts....It was the Porsche version and it was made in China...a much less expensive alternative they offered was made in Germany....just seems odd on it's face to me but who knows
I got an F9 last year when I had to replace the fuel pump. So far so good, and I like the LED status on the top of it. Given the price of OE relays today, I'd not hesitate to buy an F9, personally.

Based on the product label, the Pelican Parts parts relay (later version, 02) has a higher current rating (20A).
Although you have to wonder "why" as there was nothing wrong with the original contacts. Mine aren't burned or pitted and it is a 1995 DME relay. The issue with the original relay were poorly soldered joints.
