Timing Chain Failure – 2.0 Diesel
Timing chain failure is a well known problem on all models using the 2.0 Ingenium diesel engine, with the Range Rover Evoque being one of the models we see most often with this fault due to their popularity. The root cause is oil dilution from incomplete DPF regenerations and the construction of the chains and guides themselves. Initially causing a rattling noise on cold start and sometimes a Restricted Performance message on the dash.
If failing timing chains are left for too long, they can jump time or snap causing the pistons to hit the valves, effectively destroying the engine. The plastic guides that the chains run along can also cause other problems too. As they wear down, plastic particles from the guides can make their way into the engine oil pickup system blocking it, this can lead to spun crankshaft bearings causing a bottom end failure or turbo failures due to insufficient oil supply.
If you have failing timing chains the solution is to replace the chains along with new guides, idlers and tensioners.

Turbocharger Failure – 2.0 Diesel
Turbos on 2.0 Ingenium diesel versions of the Range Rover Evoque are known to fail. Turbo failure can manifest itself as a loss of power along with an engine management light.
If a failure is caused by an oil leak on the turbo unit itself and that leak makes its way into the exhaust system, you may notice a large amount of blue smoke coming out the exhaust, the level of smoke will likely increase under acceleration as this will cause the turbocharger to spool harder.
Sometimes, a turbocharger will give also some advanced warning of failure, you may hear a siren like whining or whistling noise that gets progressively worse. This warning should be taken as a clear message that it’s time to book your Evoque in for repairs as soon as possible.
Replacement is often not as simple as removal and fitment of a new part, because any contamination in the oil delivery system could potentially cause a new turbo to fail shortly after it is installed. When fitting new turbos at K Motors, we perform a full engine flush and will recommend replacement of parts which we feel are at risk of contamination including intercoolers, feed pipes and filter screens.

Piston Cooling Oil Jet Solenoid – 2.0 Diesel
The 2.0 diesel engine fitted to the Range Rover Evoque uses an electronically controlled solenoid to manage oil flow to the piston cooling jets. These oil jets help to regulate piston temperatures in the engine block when the engine is under load, reducing stresses and wear on the internals.
However, the solenoid used to control these jets on the 2.0 Ingenium unit is prone to failure, mainly due to coolant leaking from the thermostat housing above onto the solenoid body and connector.

Timing Belt – 2.2 Diesel
Early Discovery Sport models use the venerable 2.2 Diesel engine that can also be found in the Freelander 2 and Evoque. This engine is a dependable unit but the timing belt is an essential piece of scheduled maintenance that must not be missed.
The timing belt on the 2.2L engine needs changing every 10 years or 150,000 miles, whichever comes first. It is important to make sure this is done on or before the scheduled interval, as if it were to snap, The pistons will likely hit the valves and you’re looking at over £6k for an engine rebuild instead of some simple preventative maintenance.

AdBlue Issues – Diesel Models (2016 On)
Evoque diesel models from the 2016 model year onwards are all equipped with an SCR system, this is an emissions reduction system that uses Urea (AdBlue) to stop harmful Nitrogen Oxide (NOx) emissions coming out of the exhaust. This system is quite sensitive and can be expensive to repair if it goes wrong. If the system runs out of AdBlue, the car will become immobilised until the system is topped up, but if overfilled, the NOx sensors monitoring emissions levels can sometimes fail.
The SCR system could also start adding too much AdBlue into the system leading to increased consumption if there is a fault such as contamination or a sensor failure. If you have noticed an increase in AdBlue consumption or any other unusual behaviour, it is advised to get vehicle booked in for diagnostics.

NOx Sensor Replacement – £710 inc. VAT
DPF Failure – Diesel Models
All diesel Evoques are equipped with a DPF (Diesel Particulate Filter). The DPF is another emissions control system like SCR but this filter catches the soot emitted from the exhaust system instead of the NOx and keeps it there until it can be burnt off cleanly during DPF regeneration. Regeneration occurs passively when the vehicle sustains high temperatures on a long run such as on a motorway.
If the vehicle isn’t used for long runs like this once every couple of weeks, the DPF will fill up and an active regeneration will take place, this is where extra fuel is injected into the engine to artificially raise the internal temperatures of the engine and exhaust system. Some owners may not realise this is happening and will switch the vehicle off before a regeneration is complete, meaning the system will still be blocked. This can cause the red DPF warning light to appear on the dash with the message “Exhaust Filter Full Visit Dealer”. This is quite a common problem in urban areas.
We are experienced with DPF problems at K Motors and if diagnostics do not reveal any failed sensors we try to force a regeneration using our Autologic systems before proceeding to a manual DPF clean. Unfortunately though, sometimes an expensive new DPF will be the only option.

EGR Valve – Diesel Models
The Exhaust Gas Recirculation valve (EGR) recirculates the burnt carbon in the exhaust system back into the engine to keep emissions down. Over time a build up of carbon can prevent the valve from opening and closing properly. Excessive smoke and a loss of power along with the engine management light on the dash are the most common symptoms. Similar to DPF issues, this is most common in diesel Evoques used in urban areas with start stop traffic.

Front Hub And Bearing
If you are hearing a grinding or rumbling noise from a front corner that gets worse when turning and louder the faster you travel, this often indicates a worn front wheel bearing. To check, jack up the wheel in question and feel for play by rocking it from top to bottom. If you can feel movement then both the wheel hub and the bearing need to be replaced. Sometimes when rotating the wheel there will also be a perceived roughness as it moves.
It is important to replace a worn wheel bearing before it fails completely as the wheel may separate from the vehicle!
Front Wheel Hub And Bearing Replacement (FAG) – £438
Rear Hub And Bearing
A grinding or rumbling noise from the rear that gets worse the faster you travel often indicates a worn rear wheel bearing. To check, we would jack up the side making the noise and feel for play in the wheel by rocking the it from top to bottom. If there is any excess movement then the wheel hub and bearing need to be replaced.
It is important to replace a worn wheel bearing before it fails completely as the wheel may separate from the vehicle!

Brake Discs and Pads
If worn out brake pads are spotted early before any damage is caused to the disc then just the pads can be changed. Unlike other Range Rover models the Evoque does not have wear sensors so there is no warning light to come on. It is worthwhile to do visual checks occasionally, if you leave it until you hear the metal on metal sound then you will need to replace the discs as well as they will have been scored by the metal body of the brake pads.
Also if your brake discs are too thin and have a considerable lip on the outer circumference, changing the pads only will result in the pads not bedding in properly and squealing when the brake pedal is applied.
