Having a W124 (300 Turbo Diesel) from 92. After a rutine service check. Oil change, Air filter asf the car seemend nearly numb on the speeder. The usual roar of power in the har been replaced by a feeling that the engine doesn't get enough full or the wrong mixture. The garage (certified Mercedes) has tested afterwards but can not tell what should be wrong. Niether do they acknowlegde to experience a power loss. As they say: "It's and old car.. relax!"
Since it has only gone 280.000 km. I do think I am entitled to experience the Diesel power for a little longer!
Any idears to the cause of this?
Best regards Chris
