Range Rover Multiple Fault Codes
The Range Rover brand is a staple for modern luxury, off-road ability, and comfort. Although if your vehicle develops a fault, it could enter the dreaded limp mode, displaying warning messages on the dashboard and leaving you feeling stressed.Â
When our client recently visited our workshop, they had this exact issue on their Evoque. There was a ‘low oil’ message on the dashboard and the car was driving sluggishly.
Our team at Roade Main Garage soon stepped in to help. We diagnosed and solved the limp mode issue as we followed our strict 15-step diagnostics process.
Here’s what we did to fix it…
The Issues We Found
Once the Range Rover Evoque entered our workshop, our team began work. They could tell immediately that something was up as the engine was idling poorly and sounding rough. Not only this, but the dashboard had a ‘low oil’ warning light. There was a lot to try and fix!
As the engine was the main cause of the faults, the team began diagnosing the possible causes and used our 15-step diagnosis procedure to narrow down the issue. Our advanced diagnostics tool reads fault codes that would identify the areas to look at.
Once the customer explained the situation to us, we knew that they had taken the vehicle to the main dealer just nine weeks after a major service. Something was up.
The results of the diagnostics scan showed a total of SEVEN fault codes. The list of faults that appeared were:
- P0341-91 Camshaft position sensor circuit malfunction
- P06BE-1E Cylinder 2 glow plug
- P0299-84 Turbo under boostÂ
- P006A-84 Manifold absolute pressure flow correlationÂ
- P246B-00 Vehicle conditions incorrect for regenerationÂ
- P049C-00 EGR B excessive flow detected
- 2BAE-02 NOx Exceedance
After this investigation, we knew that serious issues arose with the customer’s Evoque and our team was surprised that the vehicle even made it here.
We knew what to do next. We needed to test certain systems and inspect under the bonnet to narrow down the various fault codes to see how we could efficiently fix the issue. These fault codes may be foreign to most people, but our team of technicians who specialise in Range Rover vehicles knew what they meant.
We performed the following tests:Â
- Verifying if the engine’s timing is accurate.
- Inspect the cam sensor for any harm and ensure it works properly.
- Examine the condition of the cam lobes and look for any signs of damage.
- Ensure that enough power is supplied to the glow plugs during operation.
- Inspect the electrical circuits of the glow plugs and visually assess the wiring for any issues.
- Examine the turbocharger for any signs of wear or damage, both inside and out.
The engine timing proved to be an issue as soon as the first test was carried out. The timing was not correct, which meant that the onboard computer didn’t know when to deploy the right amount of fuel from the fuel injection system. It also failed to understand when the inlet and exhaust valves should be opening. All of these are vital for the proper function of the engine.
This is why our customer had so many problems!
After performing the second test, our team identified no issues with the cam sensor, and it was not damaged in any way.
The cam lobe is made up of cast iron and it needs to be in perfect condition to ensure that the exhaust gasses are correctly deployed. As the lobe controls the timing and opening of the exhaust valves within the engine and in the case of our customer’s Evoque, these looked normal.
The glow plug power opened another can of worms, however. Glow plugs are used in diesel engines to heat the air and help ignite the fuel, particularly in cold weather. Our team tested the glow plugs and confirmed that they were not functioning correctly. We informed the owner that they should be replaced.
A turbocharger is essential for vehicle power and efficiency. They are used to recirculate the exhaust gases to produce more power by forcing more air into the engine. With carefully engineered blades and casing design, they are delicate parts and spin at thousands of revolutions per minute. The technicians found an issue with the turbocharger in the customer’s Evoque and therefore suggest that this also should be replaced to prevent unwanted repairs later down the line and to reduce the risk of complete engine failure.
Engine Repair Process for Range Rover Evoque
Our technician outlined every issue they found, and the steps required to fix them. Using this information, we explained everything in detail to our customers to ensure they understood the problems and suggested solutions.
We always keep our customers in the loop when it comes to diagnostics and repairs. We outline the labour and parts required and the estimated cost to leave no stone unturned. Also, we seek approval before starting any work.
Once our customer understood what needed to be done, they were happy for us to continue with the repair process to fix their Evoque.
We sourced the necessary replacement parts immediately and our repairs only use genuine Range Rover or high-quality alternatives.Â
We began working to fix the Evoque and undertook the following steps:
- Installed a new timing chain kit to fix timing issues and ensure the engine ran well.
- Swapped out the turbocharger to make sure exhaust gases flow freely and boost engine power effectively.
- Changed all four glow plugs to ensure smooth operation in cold weather.
- Replaced the oil and oil filter to provide optimal cooling and lubrication for the new timing chain installation.
Our team also went above and beyond to clean the Diesel Particulate Filter (DPF). This is not something that other workshops would do, but to go above and beyond to fix the Evoque, we knew it needed to be done.
As DPF cleaning is a labour and time-intensive job requiring the right expertise and tools, Roade Main Garage made sure that nothing was left to chance and that the vehicle would leave our workshop in peak health.
Once the fixes had been made, we cleared the fault codes and then test-drove the vehicle to ensure it was fully working. After completing precise work on the timing chain, turbocharger, and glow plug replacement, our team at Roade Main Garage ensured thorough inspection for any additional issues before returning the vehicle to the customer.
Following a successful test drive, no additional fault codes surfaced, allowing the customer to leave satisfied!
In Summary
Upon arrival of the troubled Range Rover Evoque at our workshop, our team swiftly diagnosed and addressed a range of issues. From faulty timing chains to malfunctioning glow plugs and broken turbochargers, we left no problem to chance. We also performed an oil change and cleaned the vehicle’s Diesel Particulate Filter to optimise exhaust gas filtration and prevent future issues.
Using only authentic Land Rover parts, we guarantee the highest quality repairs, ensuring every customer leaves our workshop completely satisfied.
