Personaly I would change the tranny fluid. I'm sure you will hear many opinions, but that is mine. The rough shifting is normal. The car is down shifting to help you turn or slow down. As you get used to the way the car drives it will just get smoother.

One other thing you should do is reset the transmission. Turn the ignition on (engine off) and hold the gas peddle to the floor for 60 seconds. That will reset the tranny and it will start to learn your style of driving.
Thank you for taking the time out and providing me with the helpful advice. I will reset the transmission when I use it next! I didn't know it was that simple!!!

With regards to the oil, I will speak to my local BMW specialist

You cannot mess around with anything to do with the IDrive hence my point to see an independent.
I would consider changing the transmission fluid, read the threads on here!!! You can only replace about 6 liters without a complete drain(which is very difficult even for a garage because of the torque converter). Be aware you can only use a very special oil in the auto-transmission, BMW sell it and yes it is 30 per ltr, but do not be fooled into using anything else, that will destroy the transmission. A transmission repair will be more than your car is actually worth, no debate!!
Good point to do a transmission reset just follow the guides lines (you can do it as often as you like, sometimes clears minor errors which do not come back).
Yes you will read lots about the car's issues, that is why forum's are here and this being the best of the best, but believe me you will never own a better car, I miss mine!!!
Thank you for the compliments Yes this was the colour I was after, sets the car off well - especially with the black roof!

That puts my mind at rest then!

Is it a big job to check the spark plugs? Will it be a large cost?

So you're the second member to suggest changing the transmission oil, will definitely look into this!

I noticed the sheer amount of info available on here on the 6 series compared to other forums in the UK! Everyone on here seem really helpful too!

What made you change your car? Are you considering buying another one?
