What a fascinating thread detailing a repair procedure that would be unnecessary if BMW had kept their wits about them when sourcing the cables for the HE sensor. Especially impressive is friend Hager's step-by-step PDF. Beautifully produced.
However, when my HE wiring loom starts to cook out and give trouble, I'll simply invest in GSAddict's expertise for one of his refurbished kits - at around fifty of our quid, plus FedEx - why torture yourself ?
AL on the southern Med coast.
No torture. Following the changes to the procedure makes this a pretty easy fix for anyone who has done any soldering. Even if you are new to soldered repairs, I'm sure you can find some good tutorials on YouTube. Practice a bit before you jump in on your HES, and you should be good to go.
