Peugeot 807 Common Problems and Solutions
Vibrating and Shaking
Problem:
The car is vibrating and shaking excessively when the engine is running. The car may pull to one side when driving, and there are probably some loud squealing/clunking noises.
Solution:
The ball joints in the front suspension are extremely prone to premature wear, which is what's happening here. The good news is that installing the ball joints is fairly simple, and there are plenty of online guides available that will walk you through the process. You can also order new ball joints directly from us for quick delivery.

Ball Joint
Rear Wiper Stops Spraying
Problem:
There is water in your rear wiper reservoir, but it has stopped spraying water.
Solution:
Take off the rear O/S panel that you can find behind the rear seats. You'll see a push-fit joint, and it's very likely to come apart. Pop it back into place, and your water should start to spray again.
Difficulty level
Reduced Power
Problem:
The car has lost power, and the anti-pollution fault light is lit up. The engine management light may also be on.
Solution:
It's very likely that your anti-pollution filter just needs to be changed for a new one. Browse our parts list for a replacement, and it's an easy DIY job that you can easily install yourself. If changing the filter doesn't solve the problem, then try cleaning out a few breather pipes and replacing the O2 sensor. All very straightforward jobs that anyone can do themselves.
Difficulty level
Sudden Limp Home Mode
Problem:
The throttle body starts acting erratically, and then the car goes into limp home mode.
Solution:
This is a simple software issue with your 807, so you'll need to head to a Peugeot dealer for an update.
Difficulty level
Electrical problems
Problem:
This vehicle was well known for having electrical problems of all different kinds. The below video is an example of one electrical problem:
Solution:
A lot of the time, an ECU software update can solve the problem, but you will need to fit replacement parts on some problems, depending on the exact fault.
Difficulty level
Electric window problems
Problem:
It has been known on the Peugeot 807, to have problems with the electric windows. You may have found that the windows are not winding up, or down fully. Whatever the problem, the usual cause is the electric window regulator, failing.
Solution:
You will need to fit a replacement window regulator, so as to fix the problem.

Unusually high rear tyre wear
Problem:
If you are finding that the rear tyres are wearing down far too quickly, then this is usually caused by a fault with the rear suspension.
Solution:
To resolve this issue, you will need to correctly identify which parts in the rear suspension are failing, and causing the excessive tyre wear. Once you have identified the parts and replaced them, the issue should be sorted.
Difficulty level
Side sliding door failure
Problem:
If you have noticed that the side sliding doors are not running smoothly along the runners, this is a common problem on these vehicles. Due to these doors being electrically operated, a fault with the runners can lead to failure with the motor, if the runners are not fixed quickly.
Solution:
The runners are integrated into the body work. When you change the runners, you will also need to touch up some of the paint work. Fitting new runners quickly will help preserve the motor, and will make the doors run smoothly in the runners.
Difficulty level
Chrome door handle trim peeling
Problem:
It is common on these vehicles for the chrome door handle trim to peel off.
Solution:
You can either live with this fault, or you can fit replacement door handles, in order to fix the problem. You can get secondhand replacement door handles from us, at very reasonable prices.
Difficulty level
Weak Seat Belt Locking
Problem:
The seat belt does lock when pulled quickly, but it doesn't lock as fast as it should.
Solution:
This should affect very few 807s, but if yours was built in December 2005, then it's worth checking. If you do develop this fault, then you're going to need to order a complete seat belt system replacement from our parts list.
Difficulty level
Seat Belt
Stiff Brake Pedal
Problem:
The brake pedal has become much harder to push down, and overall braking efficiency has dropped.
Solution:
Any stiffening of the brake pedal is generally a sign that your brake vacuum pump is worn out or damaged. 807s built between 2005 and 2006 are particularly prone to this issue, but it can affect almost all models. You'll need to replace the brake vacuum pump, which you can find easily in the BreakerYard online store.
