BMW 118i
Four-cylinder with variable valve lift (Valvetronic). Smooth and frugal; the Valvetronic eccentric shaft is the known weakness.
Commuter Spec
Solid four-cylinder — handles the commute, but won't raise the heartbeat.
Engine Weaknesses 5
The timing chain stretches prematurely due to a faulty chain tensioner. Plastic guide rails become brittle and break. Engine damage from chain jump is possible.
Symptoms: Rattling or clattering on cold start in the first few seconds, which improves or worsens as the engine warms up.
The Valvetronic actuator motor or eccentric shaft fails at around 150,000 km. Fault code 2A67 is typical. The engine runs but without variable valve lift control — increased fuel consumption, limp mode.
Symptoms: Judder at 2,000 rpm; rough cold start; increased fuel consumption; engine stumbling when pulling away; fault code 2A67
The VANOS solenoid valves wear and cause rpm fluctuations, power loss, and starting difficulties, especially at low revs.
Symptoms: Rpm fluctuations at idle, power loss at low revs, occasional starting difficulties.
From around 190,000 km valve stem seals tend to harden, leading to blue smoke and increased oil consumption. The vacuum pump and cam cover gasket are further typical sources of oil loss.
Symptoms: Blue smoke on cold start or when accelerating, increased oil consumption (more than 0.5 L/1,000 km).
The N46 VANOS sealing rings wear from around 100,000 km. Oil pressure drop in the VANOS unit causes timing issues. Replacing the seal kit is cheaper than a complete unit swap.
Symptoms: Ticking or tapping noise after cold start (sounds like a diesel); power loss below 3,000 rpm; increased fuel consumption; rough idle
Vehicle Weaknesses 7
The electromechanical power steering (EPS) can fail completely on 2007–2012 models. A recall was issued for certain production years.
Rear subframe is prone to severe corrosion from around 100,000 km, including through-rust. MOT failure possible. Repair often costs more than the car is worth.
Broken suspension springs and rusty spring perches are frequently flagged on the E87 per TÃœV reports. Worn track rod ends are also a known defect. Affects both front and rear axle.
Rust forms on the tailgate particularly around the badges and rear wiper. Hemmed edges and hinges can also be affected.
Water enters through faulty door seals, blocked sunroof drains, or cracked body grommets, reaching the footwell and boot. Electrical damage possible.
Rubber bushings on the rear control arms lose their elasticity. Camber change and MOT failure possible. Replace both sides simultaneously.
Handbrake and faulty brake hoses frequently fail MOT on the E87. Known inspection failure point for this generation.
