Land Rover Discovery 4 Parts
Discovery 4 (known as LR4 in North American markets) was ostensibly an update of the well-received Discovery 3 model (2004-2009), and was produced from 2009 to 2016. Cosmetic improvements brought a much more modern feel to the dashboard and infotainment systems; externally the bumpers and lights were updated, with LED lights front and rear. A choice of larger capacity 3.0 litre twin turbo diesel engines offered more power and, when mated to the 8 speed automatic gearbox (a 6 speed option was also fitted), made it one of the most impressive 4x4s on the market, with superb torque and pulling power.
This comfort and performance does come at a price however, and Discovery 4 is not a cheap car to run! The engines can be prone to turbo wear (secondary turbo drain pipe replacement upgrade can alleviate this sometimes), and faulty oil pumps can cause crankshaft oil seals to leak which, if left unchecked, can lead to oil starvation and total engine failure. Suspension bushes commonly wear, resulting in expensive suspension arm replacement. EGR valves and handbrake units suffer from the same expensive bills as the earlier Discovery 3 as with wheel bearing failure, and general electrical faults such as brake light and handbrake switches, door handles and bonnet catch micro switches can fail. Brake pipes, especially the front to rear ones, can need replacing due to corrosion being harboured between the pipes and their fixing clips.
To summarise, if you don't mind the often hefty repair bills, and like a smooth, responsive, comfortable and extremely useful vehicle, the Discovery 4 is a serious contender.
