2002 Peugeot 206 4 cyl Front Wheel Drive Manual 47000 miles
My Peugeot 206 has started to make a tinny/clunking noise underneath it when setting off in first gear when the engine is still warming up. It doesn't seem to do it once into a journey, just when the engine is still a bit cold. I have only noticed this since I had a new exhaust fitted a couple of months ago - not sure if this is related.
On 2 occasions in the last few weeks, when setting off in 1st gear in slow traffic the gearstick has jumped out as well, back into neutral without stalling the engine. Both times it happened it seemed to jolt quite heavily.
Take the vehicle back to the place you had replacement exhaust fitted and ask them to inspect underneath after you explain the symptoms to them. It sounds like they may have disturbed the gear selector bar which is quite near the exhaust on this vehicle?
