What are the known problems of the BMW X3 28i?

The N20 2.0 turbo petrol in F25 20i and 28i models can wear its timing-chain guides: listen for a rattle on a cold start and ask whether the chain has been replaced. The B48 in the G01 has a better record.

Is a petrol BMW X3 cheaper to tax than a diesel in Luxembourg?

At the same CO₂ figure, yes: petrol uses a fuel factor of 0.6 against 0.9 for diesel. A petrol X3 usually has a higher CO₂ figure than a 20d, though, so compare the two certificates.

Should I buy a used BMW X3 M40i or X3 M?

The M40i's six-cylinder is quick yet comfortable enough for daily driving. The X3 M is a full M car, with more power, firmer suspension, stronger brakes and higher running costs.
