I think you need to check it out with a mechanic. Could be anything from suspensions to interior.

Thank you RW1891. That covers quite a wide field. The car still has 6 months left on the factory warranty and is due for its next service with the dealer in May. I previously sent an email to the dealer's service manager describing all the issues but so far have not received a response.

If you hear it from the wheel well then it's most likely your control arms but a car with such low km should not have that problem. If you can't hear it on the outside then I would not worry. But it wouldn't hurt to get someone to look at it but that'll cost you $$ especially if you don't have a warranty. If it's something major, sell the car before it becomes more noticable. These newer BMW cars are literally money pits as they age. The older ones 2004 and before are bulletproof. Based on my experience driving all kinds of bmws/German cars. Too many sensors in these cars. A s class has 120 modules so imagine the pain it is to fix these. I've charged people thousands for these type of repairs. Computers take more time to fix especially if you need a 25,000 dollar scanner just to find out the problem but that doesn't always work
