Thanks loads for your tips, it's clear in my head now! I'll just keep it working then. Fortunately I received three replacement VIS motors that work with the car, so that's a plus.
Not
too bothered by the "lower performance" than my previous cars, I usually just cruise around with my 75 as that's what it does best - but I do occasionally go to the deristricted German autobahn with it, and that's where I sometimes wish it had some more power.
Not a BMW engine though, that's true! I love the character of the KV6 and much prefer the sound it makes to the straight 6 of BMWs that I had and have, but those engines were absolutely bulletproof, my 46 had 400k kilometres without any major engine repair ever, 36 running close to 300k so far not even any oil consumption. Not sure this can last that long, but I'll do my best to make it do! 170k kms as of yet though so I have to keep it long to make it there, so far I love it and much prefer it to the 46 it replaced in my "fleet" so we'll see
