Everything.
1 month after getting it the clutch cable went and I needed a new one.
The locks kept unlocking themselves
The CD changer kept skipping, got it replaced and found a dent where the idiot mechanic had wedged his screwdriver to get the old one out
Side panel came loose
Engine CUT OUT
Doesn't always go into reverse. Gears VERY crunchy.
It's a really bad car for reliability.
The Peugeot Mechanics can't find any problems. They don't even test drive them to find the problems just leave it in the garage and play about a bit.
You hit the nail on the head with this review. I have nearly identical issues with my car. I'll not be getting another. I enjoy driving the car though, but its just got too many little issues about it.
I am having similar problems with my new car. it kept on cutting out. no one could find a fault on it. it has now been at the garage for over 2 months.
I remember Mike Brewer on the TV Show Auto Trader said the 206 has a tendency to unlock itself.
