Problem 1
Citroen C1: Early clutch wear: high biting point and squeak
What goes wrong
Early cars (mainly before the 2009 facelift) had a small 180 mm clutch whose drive straps crack; later cars got a stronger 190 mm clutch.
How to check it yourself
A biting point near the top of the pedal, slipping in higher gears, or a squeak from under the car as the clutch is released.
The usual fix
Replace the clutch kit, ideally with the later larger-diameter clutch.
Signs: Clutch slipping, Harsh shifting
Problem 2
Citroen C1: Leaking water pump
What goes wrong
The water pump on early cars leaks from its seal or weep hole.
How to check it yourself
Look for coolant traces and crust around the water pump at the timing-chain end of the engine, and pressure-test.
The usual fix
Replace the water pump with the improved part, then refill and bleed. Don’t drive on low coolant.
Signs: Coolant loss, Engine overheating
Problem 3
Citroen C1: Water leaking into the cabin or boot
What goes wrong
Water gets in through the tailgate glass seal, rear light seals, or blocked scuttle drains below the windscreen.
How to check it yourself
Check the spare-wheel well and footwells after rain, clear the scuttle drains, and hose the tailgate and rear lights with someone watching inside.
The usual fix
Reseal the tailgate glass or rear lights and clear the drains; dry the carpets fully.
Signs: Water leak into cabin
