Per Hella the replacement no. is H41520191. If you join their free "aftermarket club" they cheerfully answer questions like this. The new relay is a SPDT w/diode, schematic on the side of the relay matches my old one. Waytek, inc. is closing this relay out. Five relays for $3.00 plus tax. This solved the 1995 na 940 problem which was dieing after about 10 minutes and then starting maybe 15-30 minutes later. I (hope I) discovered the probllem by putting my hand on the relay, noting it was fairly warm and then felt and heard it click when the car died(we were parked). Reving the engine to about 2500 rpm made the car only shut off momentarily, rpms dropped about 500 rpm but kept running as the relay cycled. I now have a spare in the glove compartment. My 1995 turbo 940 uses the old 35 23 608 relay that is still located far left second row under the radio. Any thoughts?
