Has anyone thought of involving Top Gear or (possibly better) Watchdog to publicise our predicament?

4 weeks ago my local garage replaced the exhaust because the flexible joint had smashed inside the exhaust pipe near to the engine. Since then it has 'whistled' he has relooked and confirmed there were no gaps and that it must be the TURBO. I'm certain this whistling never occured before the new exhaust. However, I could live with the whistling except today (26th March) I noticed a rattling noise and there was little power when I tried to accelerate (although the petrol usgae gauge swung across the rev counter hardly moved) the next thing was the car was full of exhaust fumes with noticable exhaaust coming from the pipe at the back. The garage have spent 2 and 1/2 hours taking the TURBO apart and noticed it was 'loose inside'. They intend to forward to a specialist to find the cause. The cars has done 60,000 miles. Anyone any idea please? Situation at 3rd April: I have been quoted £1400 to replace the turbo. (I too felt sick at the thought of paying this amount. The whole idea of buying a BMW is the reliabilty isn't it?) my garage suggests I may not need the exhaust and Cat replacing as they intend to 'clean' the exhaust and the heat may clean the cat sufficiently before the next MOT! However, I spoke with a neighbour who just before Xmas has had his turbo (BMW same year 2002)replaced along with his engine because the turbo sent splinters into the engine leaving him with compression in 1 chambre only! BMW have paid for his parts (approx £6000) but not his labour (approx £3000). He intends to sue the dealer where he bought it. Also, the guy who delivered my replacement turbo today told my garage this was his 8th delivery this week. Surely there is something wrong with this model why will BMW not admit it
