I have searched and haven't found any information. Has anyone been able to make the factory coolant level sensor work on there TDI swap? I see a lot of people are using the factory bottle. I thought it would be a nice feature to keep. My donor was a 2002 Jetta Thanks

Yes the vanagons used what looks like a relay or flasher. But it sends a AC signal across the probe gaps . I'll dig out the information or link tomorrow. I'm using this on my swap.

Thanks, that would be great. I haven't seen any threads on how to make it work.

The relay # is 191 919 376 A search coolant and heating flashing red light on dash -VW T25 (T3)- TECH You can also add a overheat warning to the same curciut you can use a regular LED and it will give you a flashing signal
