2014 Mini John cooper works problems

mini logo

John Cooper Works (JCW) is a British car marque now owned by BMW and it is an in-house tuning, development, and international automotive racing division for Mini vehicles. It was founded in 2002 by Michael Cooper, son of John Cooper, the racing car maker and tuner responsible for the original Mini Cooper.

In 2007, German automaker BMW acquired the rights to the name, and it bought out the company in 2008.

JCW Tuning

Cooper

The first ever JCW kit was a 126 bhp (94 kW) upgrade for the Mini Cooper. The kit consisted of the following components:

  • Flowed and ported cylinder head
  • Air filter
  • Cover injection tube
  • Uprated exhaust (from the catalytic converter back)
  • Remapped ECU
  • Decorative emblems

Despite its price tag of over €2000, this kit only offered a power increase of 11 bhp (8.2 kW), a sportier exhaust note and a crisper throttle response. The main advantage was that these improvements, though fairly minor, could be made to the Cooper without jeopardizing the factory warranty. In 2004, JCW discontinued the Cooper kit and introduced a Sound Kit for the Cooper. The Sound Kit consisted of a unique air intake system, cat-back exhaust and an ECU remap.

  1. Instrument Cluster Malfunction: Owners have experienced issues with the instrument cluster randomly blinking on and off, making chiming sounds, and showing fluctuating speedometer and tachometer readings. This problem can also affect the vehicle's turn signals.
  2. Timing Chain Tensioner Failure: Particularly prevalent in the 2013-2014 models, the timing chain tensioner failure can lead to serious engine damage if not addressed promptly.
