Took the 1999 e300 for a short drive and it's rather sluggish in first and second. But in 3rd through 5th it has a little turbo action. But I expected more.
I'm hoping a new egr transducer will make the difference.
BTW I didn't notice any performance gain after getting the maf trouble code removed.
I thought the 606 was supposed to run way better than the om617. So far the old om617 is the better performing engine. But I know the om606 gets way better fuel mileage so there's that.
My guess is the ecm is limiting fuel enrichment and turbo boost due to the egr flow issue. That has to be the performance problem at the moment.
Keep in mind I bought the car with the cel on and haven't really experienced a good running 1999 e300 yet. So far not impressed but hoping once the egr issue is resolved the performance will be there.
Miss the old mechanical Mercedes diesel. Was very straight forward and predictable.
