Renault Laguna Common Problems and Solutions
Random Stalling
Problem:
The car suddenly stalls while you're driving. This is often accompanied by battery warning lights and other dashboard warnings.
Solution:
Have a look at your engine cooling fan. If the fan itself doesn’t look damaged or worn, then it’s likely to be the fan sensor. You can find both by entering your registration on our homepage and checking our available parts for the Laguna.
Difficulty level
Engine Struggles To Start
Problem:
It’s very hard to start the engine. When you do manage to get it running, you may notice a strong smell of fuel.
Solution:
This will be your fuel pump, which is a known trouble spot for the Laguna. Check the BreakerYard parts page for the Laguna and order a more durable version.
Difficulty level
Loss of Power Steering
Problem:
Steering the car is much harder, and you can feel that you are not getting aided by power steering.
Solution:
Your hydraulic pump has either failed, or it’s on the way out. When that happens, your fluids can become contaminated. We always have pumps in store, and they are easy to install.
Difficulty level
Sticky Clutch (All Models)
Problem:
When you’re driving, the gears suddenly become much harder to change into and may even get stuck in one position.
Solution:
Affecting diesel models slightly more than others, the clutch system in the Laguna is renowned for premature failure. Installing a new clutch is quite a challenge, but there are hundreds of online videos that will walk you through the process. You can order a new clutch assembly direct from our store and have your replacement delivered straight to you.
Difficulty level
Turbo Failure (1.9DCi)
Problem:
The turbo has suddenly failed.
Solution:
The oil pressure switch on the DCi is a known problem, and if it isn't sticking, then the other issue it can cause is a leak that damages your turbo seals. That results in sudden turbo failure. If you're lucky and you catch this problem quickly enough, then you may be able to get away with simply replacing the switch. In worst-case scenarios, you’ll need to browse our parts list for a new turbo assembly.

Oil Pressure Switch
High Oil Pressure (1.0DCi)
Problem:
The oil pressure gauge is giving an extremely high reading.
Solution:
Very common on the Laguna 1.9DCi, this will be caused by a sticking oil pressure switch. Try applying lubricant to the switch, but if that doesn’t work, then it has become too worn. You’ll have to order a new switch from BreakerYard and install the working one.

Oil Pressure Sensor Switch
Knocking From Rear
Problem:
You can hear a knocking sound coming from the back of the car while driving.
Solution:
Your rear axle bushes have worn out. This is quite an easy fix, but it can be a bit fiddly. Order both bushes from our parts list and check some online guides if you’ve never done this repair before.
Difficulty level
Heater not working
Problem:
If you have noticed that the heater is not working on your Laguna, a burnt component is normally the cause of the problem. The heater control panel is usually the part affected.
Solution:
You will need to replace the heater control panel to resolve the issue.

Electric handbrake problem
Problem:
It is quite common for the electric handbrake to have problems causing the electric handbrake to fail. This could be wiring problems, a faulty solenoid or motor, or even a software problem.
Solution:
You are best having a professional looking at it, and possibly a diagnostic check run. Once the problem is identified you will be able to fix the part, otherwise you will need a new part. We can help you save money on a quality second electric hand handbrake at Breakeryard.
Difficulty level
Windows not working properly
Problem:
You may have noticed that the windows are sticking, moving slowly or not moving up and down at all. This problem lies on the faulty window regulator.
Solution:
You can remove the window regulator and try fixing it. Have a look at the video below to see how to fix it. If this does not work, you will need to replace the window regulator.

Poor acceleration at low speeds on diesel engines
Problem:
If you are having problems with the acceleration on your diesel engine, this is usually due to a faulty EGR valve. This problem may also mean that your car is consuming an unusually high amount of engine oil.
Solution:
You will have to remove the EGR Valve and try cleaning it out. If this does not solve your problem, you will need to replace the part.
Difficulty level
EGR Valve
Engine cutting out while driving
Problem:
This is a common problem with these vehicles, and one of the main causes for this is problems with the key cards.
Solution:
