Advice for buyers
What should I look for in a used BMW M140i hatchback?
Though formidably quick, the M140i can quite easily play the role of shopping car, so it will have been used in tight urban car parks and on school runs. Check the bodywork carefully for any signs of damage, including light scuffs and dents that can be expensive to repair. Also check the condition of the alloy wheels carefully, as these may well have met kerbs.
Of course, the M140i will have been driven enthusiastically too, so check the alignment of the wheels carefully. Also, check all the bodywork, including underneath, for signs of any impromptu off-road action, check the exhaust for any nasty signs of blue or black smoke, and above all check the car’s service history (we’d recommend only buying a car with a complete one) carefully, and make sure all oil changes have been carried out on time. Also look at brake discs and pads, both of which wear quickly, and also look at the general condition of the tyres. The engine and the gearbox tend to be bulletproof, and owners report few problems with them.
What are the most common problems with a used BMW M140i hatchback?
A problem with the crankshaft sensor of some examples built from 16 May and 13 July 2018 could lead to the engine going into an emergency reduced power mode, limiting performance. A BMW dealer will be able to confirm if your 1 Series is affected by this and arrange to have the sensor replaced.
Is a used BMW M140i hatchback reliable?
Petrol versions of the 1 Series did pretty well in the family car class in our most recent reliability survey by finishing in 7th place out of 31 cars surveyed. BMW as a brand doesn't have the greatest reputation, mind and finished in 21st place out of 31 manufacturers in the same survey.
