Salmon!?

Seems like a bit of a bad design if the motor just runs 'til it burns out?

Yes, indeed. AUDI uses the same relay design, but added an additional check for the relay's behaviour. Thats is more secure.

Interestingly BMW uses the same odd electrical design since the 90's! I found it on any convertible of the last 20 years equipped with hydraulic pumps.

Although I guess it's not BMW's problem, they just charge the punters for a new motor.

Unfortunately, they charge a complete hydraulic pump plus mounting. That is a business model, why to change?
