Just seeing if it is not only me.
Door creak slightly when you open or close them (mainly the front doors)
Dashboard rattle and creak (center, over bumps and rough road surface)
When starting or shutting down your engine (specifically Diesel) the dash and car vibrates or feels a little rough.
Idle very very very slightly lumpy... Smooth and consistent RPM but every so slightly lumpy. Seems fine once warmed up.
Temp reading... Well we all know about that one
Clutch is light but eventually gets a little tighter not an issue just an observation
Depending on where your steering wheel is set to be, you can feel the steering rack touch the brake pedal assembly touch slightly. Feels like the pedal clicks, try next time your at a standstill or parked up. Duncan (alfanet) only noticed it after I mentioned it to him when the car was in, another 156 and 147 did the same.
Speedometer sometimes, very rarely sticks for a millisecond and carries on.
The above is not a gripe...... More of a cars personality and it adds a little character.
