Clutch
Typical layout and location for the Clutch assembly.
Symptoms
- Clutch pedal stays flat to the floor
- Difficulty engaging gears, especially 1st and Reverse
- Pool of brake fluid under the gearbox bellhousing
Root Cause
The seals inside the concentric slave cylinder wear out. Because it is mounted inside the bellhousing on the gearbox input shaft, the entire gearbox must be removed to replace a £40 part.
How To Fix
- Check brake/clutch fluid reservoir level (it will be low).
- Gearbox must be removed to access the CSC.
- Always replace the entire clutch kit at the same time, as the leaking fluid ruins the friction plate.
- Cost: £400-800

Other Faults on This Variant
Timing Belt Failure (60,000 Mile Interval)
CriticalThe PSA 1.6 HDi engine has a 60,000-mile or 4-year timing belt interval — much shorter than most competitors. Belt failure destroys the engine. Many 207 owners are unaware of this critical maintenance item.
Injector Seal Leak (Chuffing / Black Death)
SevereCopper injector seals fail, allowing exhaust gases and unburnt diesel to escape and coat the top of the engine in a hard black tar affectionately known as 'Black Death'.
Turbo Oil Starvation and Destruction
CriticalThe 1.6 HDi (DV6) engine is infamous for destroying turbos. The cause is almost always oil sludge blocking the tiny gauze filter in the turbo oil feed pipe.
