in 12 years of D2 TD5 ownership the only time my low level alarm comes on is when there's been a leak so no it's not normalQuote:

Can I pick your brain on how the sensor is mounted, drilled through the tank?Quote:

Just let me know if you'd like a picture. I've had the Redarc in for well over 12 years in the original coolant tank and it has never cracked, leaked or incorrectly buzzed before. The only thing with it, is that you must have coolant in the water as pure water (I'm on rain water) doesn't conduct enough and the Redarc thinks it has gone dry.Quote:

Just so I get this straight, the entire BMW expansion tank fits and plumbs up ok??!!
If so, that's brilliant!
None of the aftermarket TD5 versions after safe, and Mario won't warrant the genuine one either.
.... I’m interested too, I was thinking to pop rivet a spade lug low down on tank with the rivet through a metal washer on the inside and outside of the tank to spread the clamping force and provide a seal.[emoji848]Quote:
