Scud Ing Swiss F1 Pump Relay for 599

Doesn’t answer your question, but there’s loads of experience with this over on the 360/420 forum.

I’ve no personal experience, but I gather the reviews are generally, though certainly not universally, positive.

Hi George,I installed one on my 2007 599.Despite what I have seen posted there is no way to expect a difference in shifting.I put it in as a reliability hedge. Solid state vs conventional relay. Easy install and has worked as expected. I keep the old one in the trunk as a spare. Good luck,Mike

 

The F1 pump relay (part 233100) is common to 430’s, 612’s and 599’s. The whole F1 system is more or less shared between these models. No reason to believe the performance/behaviour would be different on 599 to 430.

is there a link to this product and will it work on an early 599?

Robin- There is quite a difference in F430 and 599 pump performance requirements since the F1 pump in the F430 also powers the E-Diff.

George- There are two versions of the Scud Ing relay, one with diagnostics and one without. If I were making the change, I would go for the one without diagnostics just as a reliability upgrade. Not that I have read too much about 599 F1 relays failing. They were basically 3rd generation relays. The 30 amp ones in the early 360, CS, and 575M were known to fry, so they were replaced with 50 amp units in November 2003. Those did not have any problems until the early F430s with F1 and E-Diff using the same relay.

Jim- It is just a relay and should work on Motronic 7.3.1 (360/CS), 7.1.1 (575M, early 599 and 612), and 7.3.2 (later 599 and 612).

 

Fair point Taz- the 430 has the e-diff, so the duty cycle on the F1 pump might be a bit higher than on 599. The pump itself is the same part though (248083), so the peak current will be the same. My point is that the experiences of the 430 guys with the scud-ing relay are a very good proxy for what you might expect on a 599.

For my own part, when I took the F1 pump relay out of my car, there was charring on the terminals- this wee guy was clearly doing a lot of work. Given the cost of the standard relay (£4.95 on eurospares), it’s probably not a bad idea for any owner to keep a spare one handy, or to replace them every 5 years or so. A solid state relay is undoubtedly an improvement on the standard one, but you can proactively replace the standard relay a good many times for the cost of a scud-ing relay. Just sayin’ ...

Robin- Mine has an upgraded 30 amp relay that is pretty bulletproof. And I have a lower end spare

Affirmative, same pump in the F430 and 599, the F430 pump just has to work harder. The only complaints about the Scud relay have related to the diagnostics beeping and bothering the owners. That can be turned off, but actually no need for the diagnostics that I can see. There have been a couple of failures, and when that happens, just like with most solid state stuff, the F1 system shuts down completely.

George- Good choice. Let us know what your old one's condition is.

 

Yes, bought and installed one on my 599 about 2 years ago. I agree that the only "problem" would be the beeping as it goes about its' business, but , as mentioned , it can be turned off. As for the diagnostic aspect, I guess you only need it when something goes wrong. It works perfectly, and as it replaces a relay with a solid state component 10yrs more advanced, I considered it a worthwhile upgrade . I'm sure the Scud ING product description can give far more detail as to the benefits to the F1 pump system. As with their other products, I find they are well designed to address problems that exist in the OEM components in our cars.

 

I also have one scud Ing installed. First I had a few (often) problems that the relay didn’t turning on pump. The scud Ing changed this one with the new one. After that the new one sometimes doesn’t start too. This is not often but if happened, I need to turn off all power in car (in trunk) and start again. Ones it happened after I drove out gas station so I left with 1 engaged And without clutch (f1 pump shut down). So sometimes there is a problem that the relay doesn’t stand up after you open a car and start it. I just often drive this car so it sometimes happen.

Yes, That's correct
