Best fan relay for a 200tdi electric fan (CONCLUSION)

My other thread got locked down, but I figured I’d just post my outcome.
As I was waiting for the new sender to show up I read the install information again and realized I may have screwed up by using a small amount of Teflon tape on the sender. Took it off and made it real tight and all seems good. No leaks and it’s turning on and off as it should. The problem was compounded by the fact it is rarely needed and did work sporadically. Didn’t realize I had a problem until taking it on the beach a few times.
The fact that sadly I mostly drive it around town was the reason it never really exposed the problem.

Just like the VDO sensor it grounds via the threads. I’m glad your up and running again.

Yet another update.
My Allisport rad/spal fan and sender built into the rad wasn’t grounded to the frame.
Someone saw me struggling and made the pretty obvious suggestion. Makes me wish I had listened and just used the location on above the thermostat

The radiator is insulated by the rubber mounts and the hoses. Add a ground wire from the bolt that holds the fan on or the shroud mount to the body or frame and you're all good. You just need a small gauge wire, a 5 minute job at best.

Yeah, I did it this morning, Sadly if he hadn wandered by I’d still trying to figure it out. Makes me feel like a bit of a Jackass
