Known problems, Aygo, C1, and the Peugeot 107

People reviewing this car really like them or they don´t, there is really nothing in between. Some have had many problems and some doesnt have any and are enjoying the car.


Earier models has had some problems with engine start (startmotor).
A fix: putting a timer on the startrelay has been supplied to some of the owners. This makes it impossible to run the startengine to long (the startrelay timer stops it), and burn the electric motor.

 Many users report having problem with weak clutch mostly pre 2009 (facelift), (its a very common problem its the three wee straps that snap off one by one), then they fitted a Yaris clutch 190 mm instead of 180 mm diameter which does seam to hold together better (but still reading about lots of clutch problmens on the forums). Other known problems have been water intrusion and leaking waterpump on earlier models, also often resulting i beltfan replacement, pre facelift.
squeaky noise after clutch or hearing a grinding sound from the clutch. Common problems is release bearing / pressure plate failure,  clutch metal springs failing . Pilot bearing broken and the case that holds the disk can be broken too but from inside not the outside teethes.


somewhere in the shift linkage. Possible that there is not enough lubrication


 problem with a wheel bearing problem with a wheel bearing


pre-October 2008 107 models. In it they’ve recommended that the original 180mm clutch be replaced by a 190mm clutch to rectify premature wear, noise. and smell. They also recommend that the flywheel is checked due to fitting of a larger diameter clutch, and if required this also needs to be replaced.


water where the spare wheel goes in the back


The water comes in through the vents behind the rear bumper usually, generally the seal has split
Also check the seals of the lights, high level brake light, and the vent/hole under the catch inside the boot, then that leaves only the hatchback welt, or perhaps leakage from around the rear wiper spindle.






Some have reported MMT problems, I found this in a german forum:
 Here is the part number of the old control unit:
TOYOTA 89 530 – 700 10 … 6 L 01
AISIN 32 48 11 – 11 090 Here is the part number of the new control unit:

TOYOTA 89 530 – 700 90 
 
 rust forming on the underside of the car is crazy; exhaust especially rust.


 headlight go on the side of the road as the bumper needs to be removed to replace the bulb




 the interior light only come on when the driver’s door is opened


 for an example the right window, which can’t be moved from the drivers side. Was it a problem to put a second switch somewhere in reach point of the driver?




electric power steering ECU can break down, quite expensive to replace.


common problems are; poor door seals letting in water, front brake discs that corrode & wear prematurely & front windscreen wiper blades that only last a year

Engine
Petrol: 1KR-FE (gearbox: C551, C551A)
Piston slap, some cars rattled when cold and the engine has to be replaced.
Piston slap is when the piston has too much play against its cylinder bores. the piston moves too freely in the cylinder instead of tight. You could lose compression in cylinders as well. An indication of piston slap is a decrease in noise as the engine warms up
 3 cylinder engine, vibrate a lot and the friction coated piston gets lost the rattle begins to come.
