Any cat rattle we got we would put a block of wood above between the body then put a jack under the cat and squash ? it a little.
Hope you understand what i said and pardon my dyslexia.

Oooo.. Never thought of that. On my cayenne years ago I just dented it with a mallet as one of those was loose too. Good idea.

Ok so I returned to the transmission place. Ian the owner drove the car - in a rather spirited way - and also did some stall tests etc. It’s not the transmission apparently.
Then I went off to visit a chap called Paul Spicer in Stevenage who is a bmw expert. He took a look but wasn’t sure so I’m going to let him have the car for a day or so so he can figure it out.
I need to fix this harshness/ vibration as it’s doing my head in and I’ll just buy another car. I also know it’s not right as I had an identical X5 a few years ago along with this one and that was much smoother.

Right. It’s been a while and haven’t driven the X5 over 3k rpm so no vibration. Anyway, today I was messing about and noticed that if I turn the AC off (I always have it running) the vibration high up in the rev range is not there - it’s not as smooth as I think it should be but a vast improvement.
So it has to be either the AC compressor / clutch or something that is linked on the same belt - I haven’t had chance to take a proper look yet.
I have noticed over the last few years that the AC does make a thump as the clutch comes on and off and can be felt so maybe the engine mounts are past their best too. Investigation required.

Will do but I don’t think it’s them as they run constantly whereas the AC clutch / compressor doesn’t. I have an AC expert coming today to recharge the daughters Astra so I’ll question him..
