Part of the recall?

Great advice Dave. I remember the early days of my apprenticeship....Marina's had an in built rattle. Had so many cards off but never resolved issue.

I wouldn't mess about trying to seal it. Have a new one + gasket fitted = Peace of mind. If it is near where thermostat is located (and I don't know that it is), have that changed as well.

I have used Bluefin on same model. Very happy with result + I can revert back to normal map as and when I need to. https://www.mybluefin.co.uk/Details/ECU-Remap/BMW/3-Series-(F30-LCI)-2015->/Diesel/335d-3.0TD-313-bhp/gu66evl

BMW won't give you anything free unless they have to. I think other than that link, you are into paying for it.

LOL

Not sure. I updated mine shortly after purchase but says no updates since. What link are you using? This one only updates phones etc. https://www.bmw.com/en/footer/software-updates.html

One of my neighbours gave me this for Christmas. She knitted it herself. I like it a lot. She takes orders and can produce in most colours.

Dave is, as always, spot on. I have a similar issue but I've yet to get it done.

I agree with Dave. The IDrive update is not an issue just ensure you keep all original bills/invoices. Oh and Kwikfit is a complete no, no - even for tyres or exhausts.

Is there still air in the system? You mention burping. I'd try a pressure test on the cooling system. Will show up any leaks.

My 3 series pick up road noise too. Turn the radio up! Otherwise, try some research: https://www.google.com/search?client=firefox-b-d&q=best+tyres+for+bmw+X1+

This would be my choice when my existing run flats have worn out: https://www.tyrereviews.com/Tyre/Michelin/Pilot-Sport-4.htm I then need to invest in one of these: https://www.thewheelshop.co.uk

Yes it does sound bad. Sounds top end. Small end/s? Valve train? Its very hard to diagnose just by listening. I'd have a BMW specialist (NOT BMW dealer) have a look at it. It sounds like a diesel engine!

Not sure about all engines, Dave. Mine is N57Z. BMW deny it has one as does a main dealer (Lancasters - Bury St. Edmunds). My hand book says drive for 30 miles or 40 minutes (I think. Something like that, anyway) - then check oil level using IDrive, and with engine running. It shows an oil level gauge on screen! https://www.autoscopecarcare.com/bmw-forum/bmw-low-oil-sensor-how-do-i-know-if-my-bmw-is-low-on-oil/
