Mercedes-Benz E-Class Diesels

I just picked up a 2008 E320 Bluetec 3 weeks ago with only 38,000 km (24,000 miles). Love the car - had a Jetta TDI for 10 years and always wanted to get the E320 diesel - now my son has the Jetta.

I too have noticed a somewhat abrupt downshift just prior to stopping - but only when the engine is cold - once the engine warms up this does not happen. Will bring it up at my next stop at dealer to see if this is a problem.

Hello there!

I just recently test drove the e300 turbo with 193,000 mi on it and it drives beautifully. The car is for sale at about $7900. Every switches and buttons works fine. I am a bit concerned about the blower which doesn't blow fast on the centre console but does on the outer sides. I do think the a/c needs a bit more of charging. Rest all is fine. Would like to know your opinion.

Thanks

#585 of 608 Mileage by bdhplayer

Just purchased a used 2007 E320 Bluetec. Has around 44500 miles and so far the mileage is terrible in comparison to my 2005 E320 CDI.

I believe that one of the reasons might be that the car has 19" wheels. According to my local tire guy, the heavier tires cuts down on the mileage. Is there a reason that the 2007 would be worse than the 2005?

Also, driving from Primm, NV to the Las Vegas strip, the 2005 was in the low 40's going the speed limit.

Driving the 2007 from the strip to Primm, NV the mileage was around 28 mph doing the limit. I'm spoiled with the mileage I get on the 2005.

Any comments would be helpful.

playa, you and the tire guy are right.
if you swap in smaller/16" or 17" factory benz rims and low-rolling-resistance tires similar to factory michelin MXV-"energy" tires, you may see a significant increase in mpg and smoother ride too. also what tire pressure? you can probably bump up the pressure by a couple psi from the cushy factory-recommended setting.
another possible factor is that 05 benz diesel has a significantly different engine and fuel requirements than the 07 benz. I will bet you a DM that by now there are gurus who know how to "tune" the 07 engine to get the increased mpg that it is probably capable of. Forget about dealer service if you go in that direction however...

I took the car in and there were a few minor things including resetting the codes for the transmission.

Went ahead and swapped out the 19" tires on the 2007 to the 2005 since my son won't be putting many miles on the car.

Looks like the2007 V-6 and emission requirements are a drag on the 2007 mileage.

I have found an E320 2005 CDI sedan at a Certified Preowned dealer for 20k with 51k miles. Does this seem like a good purchase?
