When the engine reved to 3000 RPM, was the car in gear and moving? Or was the car in nuetral and the engine reved under no load? If the fuel filters were R&R lately, have seller check the fuel tank strainer. Use search to find the procedure. It can be done in 5 minutes or less.

Do you have any hills there? If you do try driving the car up a hill and see how much power it seems to have.

Putting an auto trans in gear and timing how long it takes to engage is no test of an auto trans. The best test is drive up a steep hill and make sure it doesn't slip in any gear. This would have to be done after the engine has full power. So you will havwe to get the engine running correctly first.

It sounds that U don't know too much about MB Diesels. So I suggest you let it up to the seller "who knows his stuff" to repair the car. If he can't or won't, vote with your feet.

One other thing, is the car a turbo? If it is, the air line from the intake manifold to the ALDA could be plugged or leaking. This will decrease the engine power.
