I spent lots of time in my life just down the road and never been bizarrely. I’m in the concours area which is nice, looking forward to spending Saturday cleaning it up.
Not far away now and looking forward to this one. Held at British Motor Museum Gaydon. Link below if your free.

Hi Nick
I don’t know where this is located but I’d imagine not behind a convenient little flap. The only thing I’d say is it’s removal would lead to loss of all your connected services from BMW.
Be interesting to hear your results. What sort of gain is he quoting?
I went piggy back Remus which was the smallest increase in view of reliability mainly.
O right the whole thing needs replacing. If on the diagram it has a part code I’d prob get on to a bmw specialist eg https://www.bmwautoparts.net/en
Least you have the diagram you can email if no part number.
Sorry cant help anymore than that.
