E270 CDI performance problems
When traveling with revs below 1800 the car is dead and as soon as the revs go beyond 1800 you can year that slight diesel knock the engine makes and then it pulls off like it should do.
What could be the problem?
The other thing I noticed is when the car is started when it is cold it used to have a loud diesel knock and as soon as it is hot the engine runs softer. Now the engine sound the same when ever it is cold or hot. Don't know what it means.
Another problem the car is extremely heavy on fuel.
Any help, suggestions will be appreciated.
