But that chip is for the Motronic -404.
You mention
"UK 1997 e34 540iA Touring"
that probably has the newer Motronic -484, as also used in early E38.
My chip does not work on the -484 Motronic. The chaps in Germany have tried it, but engine did not start. They assume it is caused by the EWS in the -484.
I have heard that on the -484 you need to reprogram the new chip also the EWS data of the individual car.
According to Real OEM my car was manufactured in Feb 1996, but it was registered in 1997 long after the e39 was already on sale.

So does that mean your chip will work? Do tell us more....what gains and how much?
