Mine has all of the above. Here's the page on the manual again, no dice on tech bulletin but I do have a separate Bosch K Jet tech book/shop manual, I'll take a gander for any narrative.

Erik's Euro had one - his 78 US did not. I wired into the circuit.

When I had hot start problems, it was the temp sensor on the solenoid above - 928.605.104.00 that had failed. Could not find one that did not cost more to ship than the item, so I found a 924.047.131.851D - same function, but has a M10x1 thread, vs M14x1.5 on the 928 part. I just made an adaptor for it. - works fine. If the 928 part is NLA, try the 924 number.
