V6 engine gremlims !

I have an 98 E280 V6 (UK model) , It's suffering from an engine problem that means it has very little power at full throttle , it seems to have normal power at half throttle and shifts well through the gears but under full acceleration or in kickdown it has a huge flat spot around 4800 rpm and bangs through the gears .
It has also developed a noise at around 900 rpm that seems to come from the air-con compressor , its a clicking / knocking noise . I dont think its connected to the power loss problem .
The ignition key also failed a couple of days ago so it hasn't been a great week .
All this is should be covered under the MB warranty and the car is booked in early next month but I would appreciate any advice so I dont get mislead .
Cheers Alan
