Peugeot 407 Common Problems and Solutions

Power steering stopped working

Problem:

The 407 gets more difficult to steer, and the power steering unit gets hot to the touch.

Models affected:

Solution:

The electric power-assisted steering system (EPAS) has probably come to its end of life and will need to be replaced. Before you start looking for a replacement on our 407 parts list, try checking the battery and the alternator. There's a small chance that the EPAS unit isn't getting the power it needs, and replacing a battery or alternator is a little easier than replacing the EPAS unit.

Worn Front Tyres and Noise From Car Front When Driving

Problem:

When you're driving at a constant speed, you can hear a noise coming from the front of the car. You will also see high levels of wear on the edge of your front tyres.

Models affected:

Solution:

This should only happen if you have bought your 407 second-hand. The noise and the worn tyres are due to someone installing the wrong type of front suspension springs. You'll need to remove them, buy replacements from our store, and install them. Don't forget to check and adjust the geometry of the front wheels once you have installed the new springs, as you may also need to replace the front tyres.

Loss of Power in Turbocharger (1.6-ltr HDI Models)

Problem:

Your turbocharger has dropped power levels. Sometimes, this will be accompanied by a whistling sound as you drive.

Models affected:

Solution:

This will be a damaged turbocharger intake pipe. Get up close to it and check for cracks and holes. If the damage is minor, then you may be able to get away with making a repair with some glue. If the holes are too large or the damage too extensive, then you will need to order a replacement turbocharger suction pipe from our drop-down list.

Airbag Control Indicator is Lit Up

Problem:

The airbag control indicator is illuminated on your dashboard.

Models affected:

Solution:

You will probably have an open coil airbag coil circuit. That means you'll need to replace the multifunction switch to get rid of the light and repair the issue. We can deliver the replacement switch straight to your home or place of work, and replacing the switch takes just a few minutes.

Faulty Window Wipers

Problem:

When the door is unlocked, or the door is left open, the window wipers turn on.

Models affected:

Solution:

This affects a lot of 407s, especially older models. It's because the wiper motor is prone to degrade quickly. You can order a replacement from our 407 parts page and install it in under two minutes.

Creaking While Driving

Problem:

You can hear a creaking sound coming from the front of the car, particularly when driving over rougher surfaces.

Models affected:

Solution:

Have a check of your front suspensions. In most cases, the sound is being caused by excessive friction between your upper front suspensions joints. You won't need to replace any parts; it's simply a lubrication issue. Take off the front suspension struts and remove the friction washer. Lubricate the bearings and put the struts back together. The sound should be gone.

Noisy Front Wheels

Problem:

You can hear a constant noise coming from your front wheels when driving.

Models affected:

Solution:

This is down to some poor construction of the front wheel bearings. The best solution is going to replace the existing NSK bearings with more suitable SNR types. We have a wide range of wheel bearings for the 407, so you'll have no problems finding the perfect type.

Rough Revving

Problem:

The engine feels rough when revving it — often accompanied by a feeling of sluggishness when you're revving.

Models affected:

Solution:

In most cases, this will be due to a faulty exhaust gas recirculation valve. We can deliver a replacement to you very quickly. However, there may be other causes, such as a sticky throttle or faulty injectors. If replacing the exhaust gas recirculation valve doesn't solve the problem, then check your throttle and injectors, replacing anything that seems worn or degraded.

Models affected:

Solution:

This problem is caused by a faulty motor, which will need to be replaced.

Running problems

Problem:

The EGR valves can cause a lot of different running problems, if they are not working properly. You may have noticed that there is poor idling, loss of power, surging or engine hesitation. Any of these symptoms could be caused by the faulty EGR valves.

Models affected:

Solution:

You can clean out the EGR valves, to fix the problem. Watch the video, for an idea on how to clean an EGR valve:

PEF warning light

Problem:

If you have noticed that the PEF warning light has appeared on the dashboard, then you have a problem with the PEF (Peugeot Emissions Filter). This filter needs to get hot enough to burn off any unwanted particles, but this can not happen if you only use the car to drive around town.

Models affected:

Solution:

You can try taking the car out onto the motorway, or onto an a-road and driving the car at 2500 rpm for about 10-15 minutes, in order to allow the PEF to get hot enough to burn off these unwanted particles. This should solve the problem.

Clutch problems

Problem:

It is known on these cars for the clutch to fail early. If the clutch is about to fail, then you will notice that it suddenly feels very heavy.

Models affected:

Solution:

The only way to fix this, is to fit a new clutch.

5

Side indicator warning light

Problem:

If you have noticed that the side indicator warning light has appeared on the dashboard, then it is usually because there is a problem with the sensor or the wiring. This is a common fault on the 407. You may also have side indicators that work, but due to the faulty sensor or wiring, the warning light is on.

Models affected:

Solution:

You will need to identify whether it is the sensor, or the wiring that is causing the error. You will need to sort the wiring, or replace the sensor to sort this problem.
