Question 1

What are the known problems of the BMW 420i and 428i petrol engines?

Accepted Answer

Early N20 four-cylinders, in 4 Series built until about 2016, can wear their timing-chain guides: listen for a whine or rattle, especially from cold. The B48 that followed is considered more robust.

Question 2

Is a used BMW M440i a good buy?

Accepted Answer

Its 3.0-litre B58 straight six is regarded as strong and durable, and in the second generation it comes with 48-volt mild-hybrid assistance, usually with xDrive. Check the brakes, the tyres and any sign of modification.

Question 3

How much road tax does a petrol BMW 4 Series pay in Luxembourg?

Accepted Answer

Its CO₂ figure × 0.6 × a band factor that rises with emissions, so a 420i costs much less to tax than an M440i. A petrol car at 150 g/km pays €99 a year, and one at 200 g/km €192.

Question 4

Which petrol versions does the new BMW 4 Series come in?

Accepted Answer

The 420i with 184 PS, the 430i xDrive with 245 PS and the M440i xDrive with 392 PS, each as a Coupé, Cabriolet or Gran Coupé and each with an automatic gearbox.
