    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?
  • I have not been searching for prices on E320 CDIs but, for what it is worth, I can tell you that we have an E320 CDI that we bought new. We would not sell it for 20k.
  • Has anyone compared the new 2012 E class engines? I'm curious to hear about the performance of the diesel against the new gas engine. Thank

    The 2012 blutec hasn't changed....so it's performance hasn't changed.
  • I am looking for my next car and have been researching into the MB E-class diesels for the past few weeks. Overall I think the car has a great presence and very good feedback on performance and fit/finish. I am close to making my purchase. I have an offer for $48K for a 2011 new car equipped with the premium 2 package? Should I take it?
    Also can someone advise on how much it costs to replace the urea fluid periodically? Can this be done at home without going to the dealer?

    thanks a bunch all.

    that's a great price for a $58K car. I leased my e bluetec, my first diesel, in August and I love the car.

    BlueTec fluid can easily be filled by you for about 1/3 the price of having a Mercedes dealer do the job. You only have to refill the tank every 10K miles or so and you can buy the fluid almost anywhere these days...or just go to a VW dealer to buy it if that's easier or you feel more comfortable.

    If it will help your decision, mercedes leasing gives a residual value of about 76% after two years. That's 76% of the MSRP. That's what they think the car will be worth in 24 months. If they're right, you'll drive that car for 24 months for $3000 depreciation. Consider leasing by the way....ask about a 24 month lease on that car and you may be shocked at how little it costs.
  • Thanks ghstudio. Are there instructions available online on how the bluetec fluid can be refilled? Also have you purchased the MB prepaid maintenance? Is it worth it?
  • ghstudioghstudio Posts: 968
    yes, I purchased mercedes prepaid maintenance for my 24K lease...not sure what the MSRP was but they allowed me to residualize it, so I only pay 23% of the MSRP. I think it may have cost me $200 for the A and B maintenance. It's not at all clear if you really can residualize maintenance...some dealers seem to allow it, others don't....I have no idea what Mercedes finance says and apparently they don't care which was dealers go on this because there have been reports of people who have residualized maintenance and others where the dealer says it's not allowed.

    Take your best shot :)
  • Thanks. Let me restate the question then: Has anyone compared the new 2012 gas engine to the Bluetec?
  • i thought i saw in past post about selling an e-class mb diesel. any ideas on how i might sell an original owner 2006 e-class cdi with 18,000 original miles, garage kept-no snow, salt or ice, show room condition. not sure what asking price should start at. any thoughts or perhaps there is no damand. just not sure.

    thanks, henry

    You might want to post details over in our Real-World Trade-In Values discussion. There are some people in the auto biz who hang out there and might know what the demand is like in your neck of the woods (not to mention a good asking price).

  • I have a 2005 E320 CDI with 81,000 miles. The front end is significantly lower than the rear. Front wheels are almost touching the wheel well. Car cannot be driven as a result. Anybody experienced this before? I don't see any error message on display board. Any input is appreciated. Thanks.
  • I am in the market for a 06 CDI. How much do you want for it and where are you? I am in Nevada. Thank you.
  • hussell: just sold 2006 e320 cdi----asked 30,000 and got it. had 19,000 miles-no salt, snow. garaged kept whole time and show room condition. new owner got great deal. thanks for inquiry.

    Does anyone know if there is any special maintenance required for E350 BLUETEC as opposed to regular E350? Are there any disadvantages to leasing E350 Bluetec as opposed to regular E350?

    How much does extra maintenance costs and how often it has to be done?
  • ghstudioghstudio Posts: 968
    The "bluetec" fluid tank needs to be refilled every 10,000 miles....this costs $99 at Mercedes and far less if you do it yourself (very very easy). There are different filters....but if you lease, buy the mercedes maintenance as part of the lease and you will both save money and not have to worry about any maintenance costs.
  • eric312eric312 Posts: 71
    I drive about 7000/year and plan on getting a lease with 7500/year so will have the car for about 15,000 miles. Do you still think its worth buying the maintenance plan?

    Is the "bluetec" fluid only additional maintenance on bluetec vs regular E350?

    Hi there, I am new to this forum and I would like to find out if there are any incentives when purchasing an e350 with european delivery other than the 7% off MSRP and no destination charge.
  • ghstudioghstudio Posts: 968
    The mercedes lease is a little unique in that they seem to require that you do all the things in the A and B services. You will only need to prepay the A (10,000) mile service which will be inexpensive....I think the only extra is bluetec fluid...I think the cost of filters is included.

    The maintenance plan on the diesel might cost more than the gas car because of the filter cost. Lot's of mights, but my dealer was very confused so I just paid the gas maintenance and they residualized it so I only paid about $250 for the A and B service.....a great deal.

    Hi cewlcid,

    We did the european delivery in 2005. It was one of the best vacation ever. You will be treated very well by the MB staff. Touring the MB factory and museum were outstanding. Driving your new MB in the autobahn at speeds over 100 mph is priceless! I would definitely do it again for these experiences. Please check MB european delivery program in regards to 2 for 1 plane fare. Sometimes they offer it. You also get a free night at one of the hotels. No other freebies is included.

    Enjoy!

    I am having the exact same issue with my 2005 e320 CDI. Happened infrequently over the past few years but now is almost daily.

    Did anyone ever figure out what this is? Any update or link to a more recent post would be appreciated.
