Fixing Warning Messages and Limp Mode on a Range Rover Evoque
Range Rover is a staple for modern luxury. If you experience warning messages and enter the dreaded limp mode then something serious is up. Your engine is the beating heart of your vehicle and all the components need to work perfectly to keep you on the road, so limp mode shows us clearly – something is up.
When our customers came to visit our workshop, their Evoque was in limp mode and was displaying low-oil level warning messages on the dashboard.
Luckily our expert team was on hand to diagnose and repair the issue, following our thorough 15-step diagnostic procedure, this is how we repaired the issues.
The Faults We Discovered
As soon as it entered our workshop, our expert team were on hand immediately and knew something was up. The engine sounded rough and idled poorly, the engine management light was on, the vehicle entered limp mode and an oil level warning message appeared on the dashboard. A lot was at fault, it seemed!
As the engine was the main culprit, our team dug deeper into the possible causes and began our 15-step diagnostic procedure. We began by using a specialist diagnostics machine to read fault codes and narrow down the faults that had caused our customer’s vehicle to enter limp mode.
After the customer had explained their situation, we knew that the vehicle had previously visited the dealer, with a service being completed just nine weeks ago, but something was not right.
From the diagnostics test, our technicians unearthed the following SEVEN fault codes. The list of faults it turned out to be was mesmerising:
- P0341-91 Camshaft position sensor circuit malfunction
- P06BE-1E Cylinder 2 glow plug
- P0299-84 Turbo under boost
- P006A-84 Manifold absolute pressure flow correlation
- P246B-00 Vehicle conditions incorrect for regeneration
- P049C-00 EGR B excessive flow detected
- 2BAE-02 NOx Exceedance
We knew that the issues were substantial. It was incredible that the car had made it to our workshop!
From here, our team of expert technicians knew which tests to carry out after recognising the fault codes. From the outside, these codes and explanations might not mean much, but our specialist team has vast experience handling extensive engine repairs and diagnostics with Land Rover vehicles.
So they continued with their detective skills and performed the following tests:
- Checking to see if the engine’s timing was correct.
- Check the cam sensor for damage and see if it functions correctly.
- Checking the cam lobe condition and if any damage had occurred.
- Check power to glow plugs to see if sufficient power was delivered during operation.
- Check electrical circuits of glow plugs, and visual inspection of the wiring to see the condition.
- Check the turbocharger for wear or damage both externally and internally.
After the results of the first test, our technicians realised the engine timing was affected. It wasn’t correctly informing the onboard computer when to deploy fuel from the fuel injectors, when to open inlet and exhaust valves and when to release exhaust gasses. These are all crucial in the proper function of a diesel engine.
No wonder the customer had so many problems with their vehicle!
The second test indicated that there were no problems with the condition or function of the cam sensor as it was not damaged.
The cam lobe is made from cast iron and its condition is paramount to the correct deployment of exhaust gases in an engine. This is because the cam lobe is responsible for the timing and opening of the exhaust and intake valves during engine operation. Luckily, the condition looked normal.
The power of the glow plugs uncovered a different story. As the glow plugs are responsible for giving the incoming air a better chance to ignite during cold weather, they must function correctly. However, our technicians tested and concluded that the glow plugs were not functioning as they should, informing our customer that they should be replaced.
The turbocharger is also vital in the function of harnessing exhaust gases to produce more power. They have precision-engineered blades and housings which carefully control otherwise wasted exhaust gases to help force more air into the engine. Uncovering an issue with the customer’s turbo meant our technicians also recommended they replace the unit to ensure optimum engine condition and prevent catastrophic engine repairs later down the line.
Engine Repair Procedure for the Range Rover Evoque
Once all issues were uncovered, our team of expert technicians detailed every solution needed to fix our customer’s vehicle. Then over the phone, we explained each step we undertook to diagnose the issues with their vehicle and listed the recommended repairs.
Ensuring our customers are always in the loop, Garden City Garage communicates diagnosis, costs, and repair time for our clients and always seeks approval before beginning any work.
Our customer in this case was very understanding and gave us the go-ahead to undertake this extensive repair procedure.
Using only genuine Land Rover parts, we sourced all we needed to turn around the repair efficiently and began working.
The following repairs were made:
- Replaced the timing chain kit to ensure that timing is corrected and the engine will run optimally.
- Replaced the turbocharger to ensure that the exhaust gases were free-flowing and effectively boosted the engine power when called upon.
- Each of the four glow plugs was replaced to make sure the Evoque ran smoothly all the time, even in cold winters.
- The oil and oil filter was replaced to ensure the best cooling and lubrication for the new timing chain install.
Plus, our team cleaned the Diesel Particulate Filter (DPF). This was the final piece of the puzzle to remove any doubt that the vehicle would not function as it should. We go above and beyond to ensure the vehicle is running in peak health before it leaves our workshop.
Not many garages will undertake a DPF clean as it is an extensive job that requires expert knowledge and equipment. Whilst the DPF was not the main culprit, other garages could feel it was not necessary to clean, but Garden City Garages takes the utmost care of our customer’s vehicles.
The final stage was to clear the long list of fault codes and test drive the Range Rover. After precision work was required for such an invasive task of the timing chain, turbocharger and glow plug replacement, our team wanted to make sure the vehicle had no other issues before handing it back to our customer.
After a successful test drive, no further fault codes appeared and the customer was able to drive away happy!
In Summary
After the troubled Range Rover Evoque entered our workshop, our team knew what to do to diagnose and fix it. A list of seven fault codes appeared after our expert diagnosis, so we addressed everything from faulty timing chains, non-functioning glow plugs, broken turbochargers and a fresh oil change. No stone was left unturned.
We even cleaned out the vehicle’s Diesel Particulate Filter to ensure optimum filtering of exhaust gases to prevent further problems later down the line.
Only using genuine Land Rover parts, we ensure every customer has the best quality repair possible, leaving our workshop with complete satisfaction and a smile.
