Renault Megane Common Problems and Solutions
High Oil Pressure
Problem:
The oil pressure is excessively high.
Solution:
The main cause of high oil pressure readings is usually because the oil isn't flowing properly through the engine. This can increase friction, which might lead to a fire. In Meganes, a common issue is a faulty oil-pressure solenoid valve. Buy a replacement valve and fit the new one. You can purchase this from our range of parts today.
Difficulty level
Power Steering Fault
Problem:
The power steering system fails to activate, making driving much more difficult.
Solution:
This is often caused by the battery not being in good enough condition. Your first task will be to replace the battery, which is much easier to do yourself than you might think, and you can acquire a replacement battery very quickly, easily, and at a low cost – get a quote from us today! You will also need to perform a full system reboot, but this is a very simple process that you can do yourself.
Difficulty level
Water in Passenger Door Pocket
Problem:
Water has collected in the passenger door pocket, but there is no dampness on the door panel itself or on the floor surrounding the door.
Solution:
This is a common fault, and a Renault dealer will usually carry out the repairs free of charge. The problem lies with the plastic sheet fitted behind the door card, which has either become worn or has come loose from its mountings.
Difficulty level
Poor performance
Problem:
On the diesel versions of the Megane, you might notice that your car may have started to experience significantly reduced performance, with the DPF light illuminating on your dashboard. The DPF (Diesel Particulate Filter) is responsible for reducing emissions in the exhaust system, and if you do a lot of driving around towns or cities, it may not get hot enough to burn off the harmful particulates.
Solution:
Firstly, driving at a steady speed in third gear for about 10 minutes can help warm up the DPF filter and burn off the particulates, which will turn off the warning light on the dashboard. If this does not work, you will need to replace the DPF filter, which also requires that you replace the oil and oil filter at the same time.
Difficulty level
Heating fan problems
Problem:
If you have noticed that some of the speed settings on your heating dial are not working, then it is likely that you have a faulty heater resistor on your Megane.
Solution:
You will need to fit a new resistor to resolve this issue. Search for your replacement Renault Megane heating parts on Breakeryard.com to find the correct parts at the best price.

Electric windows problem
Problem:
It's quite common for the electric windows to fail on the Megane. You may have noticed hesitation or slow movement of the windows when opening or closing, which could be caused by a faulty window regulator.
Solution:
To resolve this issue, try fixing the window regulator by watching the video below. If this does not work, you will need to replace the faulty regulator with a new one. Look for a replacement window regulator mechanism here.

Window Regulator Mechanism
Engine vibrating/whining
Problem:
You might notice that the engine vibrates and/or makes a whining noise, especially when it is cold and you first start it. Two possible causes are the inlet pipe vibrating or a broken clip on the fuel line, which can cause it to rub against the air conditioning hoses.
Solution:
You will need to identify the source of the noise and rattling and then take the appropriate action to resolve the problem, replacing any faulty parts.
Difficulty level
Poor engine idling and running
Problem:
If you notice that the engine on your Megane is running roughly, not idling well, or stuttering a bit, then you most likely have a fault with your ignition coils.
Solution:
You will need to replace the ignition coils to resolve this issue. It is advised that you replace all four coils simultaneously. Look for Renault Megane electrical parts on Breakeryard.com.

Ignition Coil
Shredded Cam Belt
Problem:
When the cambelt is shredding, it will cause a loss of compression and the potential for bent exhaust valves.
Solution:
Normally, this issue is only found with the Megane Estate 1.5 diesel 08 plates. You'll need to purchase a cambelt kit, as well as a water pump and new exhaust valves. Sometimes, the problem will recur, indicating that your tensioner may be misaligned or the belt is over-tensioned. You should try adjusting the cambelt, and if that doesn't resolve the issue, you'll need to replace the tensioner. Find your replacement tensioner here.
Difficulty level
Airbag Light On
Problem:
The airbag warning light is illuminated, signalling a fault.
Solution:
This is a common issue with newer models, but it can be quite an easy fix. If you've recently adjusted the seats, you might have damaged the connection to the seat belt pre-tensioners. If the connections seem fine, however, you'll need to visit a Renault dealer for a complete diagnostic check.
Difficulty level
Fuel Leaking
Problem:
If your Megane is leaking fuel onto the road while you're driving, you could be creating a serious hazard for other drivers. This was a common problem with Meganes manufactured in 2018 and 2019, which led to a recall.
Solution:
This is very likely a problem with the fuel line. It can be resolved by using plastic glue if you can find the leak. You must not ignore the issue because if fuel leaks onto your exhaust system, there is a risk that the car could catch fire. Even if you make the repair, it's advisable to take it to a Renault dealership because of that risk.
Difficulty level
Catalytic Converter Malfunction
Problem:
The catalytic converter is malfunctioning, resulting in higher nitrogen oxide emissions.
Solution:
This issue led to a recall of all Megane IV models produced in 2019. It most commonly affects XFB and XFE K9L generation 8 models. You can replace the catalytic converter yourself, but you will need welding equipment to remove the old one. Shop for your catalytic converter on our website.
