BMW 2 Series Active/Gran Tourer (F45/F46) Common Problems & Reliability
The 2 Series Active Tourer (F45) and Gran Tourer (F46) were a radical departure for BMW, representing its first foray into both the MPV segment and front-wheel-drive architectures. Designed to prioritise practicality over ultimate driving dynamics, these models target young families and older buyers looking for easy access, versatile seating, and a premium cabin. The engine lineup is predominantly composed of the modular B-series engines, notably the 1.5-litre B38 three-cylinder petrol and the B37 three-cylinder diesel. These engines are generally robust, but early models can suffer from thrust bearing wear in manual cars and EGR cooler issues in the diesels, which have been subject to widespread UK recall campaigns. When assessing a used example, inspect the cabin thoroughly for heavy wear and tear typical of family use, such as damaged seat bolsters or broken trim pieces. The complex folding rear seats should operate smoothly, and on plug-in hybrid variants (225xe), check the health of the high-voltage battery and ensure the transition between electric and combustion power is seamless.

Most Common BMW 2 Series Active/Gran Tourer (F45/F46) Faults & Repair Costs
EGR Cooler Leak
Like many BMW diesels of this era, the EGR cooler is prone to leaking coolant internally and causing a fire risk. Affected by major BMW UK recall campaigns.
Unexplained drop in coolant level, Sweet glycol smell through cabin ventilation, Engine management light or soot around cooler
- Check BMW dealer history for recall code completion
- Inspect coolant expansion tank for level drops
- Look for soot residue behind the radiator and intake manifold
Gearbox Selector Spring Failure
A small torsion spring inside the Aisin Steptronic automatic gear selector mechanism breaks, meaning the vehicle cannot verify Park position and throws a dashboard warning on shutdown.
"Secure vehicle with parking brake when stopping" warning, Audible chime when shifting into Park, Error message stays on iDrive
- Shift into Park and turn off ignition to check for warnings
- Check if upgraded shifter spring or complete lever unit has been fitted
Front Wishbone Bushes
The heavy front end on this UKL2 FWD platform wears through the rear hydro-bushes of the front lower wishbones quickly, causing vague steering response and knocking over speed bumps.
Knocking noise over speed cushions and rough tarmac, Vagueness under hard braking, Uneven inner shoulder tyre wear
- Inspect lower wishbone rear rubber bushes for oil leaks or tearing
- Listen for clunks over speed bumps on the test drive
Engine Mounts
The upper hydraulic engine mount (particularly on 3-cylinder B38 and B37 models) can perish and leak its hydraulic damping fluid, causing harsh vibrations in the cabin at idle.
Excessive vibration through steering wheel and floor at idle, Thump when starting or stopping the engine, Black oil staining below the top driver-side mount
- Look down at the driver-side engine mount for tears or leaked hydraulic oil
- Feel for excessive cabin vibration when restarting with stop-start
Buying a used BMW 2 Series Active/Gran Tourer (F45/F46)? Always check for hidden finance and write-off history.
Mechanical problems are only half the battle. Over 1 in 3 UK used cars checked have unpaid finance or accident write-off records that could cause you to lose the car or thousands in value.
