New E Class EU4 320 disel

[MSG2004]

Had the Avantgarde version for three days whilst my C class went in for warranty repairs. The car flew as it was so powerful and the massive wheels kept it stuck to the road. I like the way the door mirrors folder automatically after getting out of the car and not before - the leather seats we a bit slippery but i was trashing the car



My bro has from new an S class about 18mths old - that has the 320 disel as well but the older version - night and day difference - i've never thought of buying a disel, but the EU4 has made me think again and the mileage even when trashed was good.

There are 2 EU4 diesels - the new V6 and the old straight 6. Both are EU4 as they have particle filters. I've not driven the V6, but the straight 6 flies and the V6 has a little more power still. I suspect the difference is more down to the weight difference between the S and the new E than anything to do with EU numbers. Actually the EU4's are less efficient as the particle filters strangle the exhaust. If your bro has an early EU4 320 then it will be slower as the initial ones were a problem with lots of people complaining about the economy as MB turned up the fuel to compensate for the filter.

I've just bought my first diesel. An EU3 E270. Thats after many years with petrol mercs. It is a little harsher and louder that the old 2.4 V6, but the power and economy more than make up for it. Blasting along to work every morning with the computer showing 39 mpg when my 240 was slower and showed 31 if I was lucky. I also went for the upgraded wheels and suspension as I agree it make it a different proposition. I certainly haven't regretted it.

Watch the new V6 320cdi. There are problems with them. Some threads here but a lot mor ethat have not got on this site yet. The diesel is seducing new owners into Mercredes but then they are finding problems. Electrics and Customer service again.

E320 cdi EU4

Hi All,

eu 4 is about permitted particulates & NOx levels in exhaust.

One of the methods used to achieve this is a particulate filter. As an example Peugot have had a lot of trouble with these ,likewise VW. Not certinthe C class is fitted withone with the 320 cdi engine, or the clk either.

Can vouch the v6 pulls like a train, though. and, initially doesnt seeem too bad on fuel. done 35 MPG on the first 1600 miles, however little town work,& Mways not above 75 till 1000 miles was cleared, and the upper 1/2 of the performance envelope remains to be explored.


as fitted in my CLK 2000rpm gives 80mph, a long legged meaty beast !

I agree about the newer diesels having problems. My 1998 E 300 diesel seems to be bombproof but my daughter bought a 320 diesel avantguard 2002 model and had so many problems she sold sold it at a loss and now runs a peugeot diesel .

EU4 does not mean it has a particulate filter and as far as I know they are still not fitted as standard in the UK on MB's.

eu 5 , 4, etc

http://en.wikipedia.org/wiki/Image:Euronorms_Diesel.png


a diagram of the path to euro 5 for diesel cars.

How a manafacturer gets there is upto them.

euro1 engines had better fuelfigs, as they had higher compression ratios. Unfortunately to reach the later euro levels , to bring NOx values down, one method was to lower compression ratio to lower combustion temp, which leads to lower NOx values.

In the truckworld, many manufactures reach eu4 with the addition of a urea solution into the post engine exhaust stream + cataylitic etc, (basis of blue tec,but in the truck arena known as SCR, Stratified cataylitic reduction) however MAN managed to reach the standard with EGR, exhaustgas recirculation alone. Egr has the same effect of lowering combustion temp & nox values. for eu 5 it is expected both techonoligies will be required.





hence the fitment ofEGR equipement on cars at present, it is not for reburn, but to lower combustion temp, by lowering o2 content.

Diesel particulate filters are not used now on most MB models.
I can confirm that the current E class diesels do not have a diesel particulate filter.

In fact, the only vehicles that are now fitted as standard with DPF are the ML and GL 320/420 CDI’s and the S320CDI. DPF is not even listed as an option for other models.

On Olaf's point about 320cdi's, I don't know where he gets the info but on this forum and others I visit the 320cdi has been very reliable indeed. And the E class finished in the top 10 in the 2008 JD Power survey while the 5 series finished 45th (having finished 54th the year before).

Since the facelift the E class has been transformed appears to be the pretty general view -confirmed by mechanics at my local MB dealership too.

Yep, my E320 CDI has been very reliable so far. Mid range acceleration is excellent. Shown up a fair few sports cars (within legal limits)......

As the post was from 2005 then I expect that was due to the issues regarding the first 211's and the electrics.

Hi all,
thanx to you all for the replies as always a lot of info to take in.....so I shouldn't have any worries about purchasing a E320cdi EU4?.

Rgds.

Thanks. I hadn't noticed it was a blast from the past. My mistake.

The transmission oil cooler of automatics is sited in the radiator matrix, so failure can lead to coolant entering the transmission and destroying it, leaving the owner with a bill of £4k - £6k. MB responded that this fault only occurred in cars manufactured between 2000 - 2003 and only when a Valeo radiator is fitted, but has occurred in later cars. By August 2008 there was an epidemic of failures with fresh reports every couple of days, dealers quoting £11k to fix and MB usually refusing to pay which effectively writes off a 2003 E Class as scrap. Also affects 2004 registered E Class.

Reading honest John's report is VERY WORRYING.
I was under the impression that post 04 Mercs were solid and back to their best. Considering an E270/320 cdi to be safe I thought of touching nothing older than a 54 plate.
Now after reading his comments to reduce any problems it's best to stick to a facelift version and one that was built 2006.
THIS IS HORRENDOUS AND GIVES A DAMNING REPORT - MERC SHOULD BE EMBARRASSED.
It seems that just when it appears safe to buy a car post a certain age, this date is then brought forward.
I thought things had got better with Merc post 2004 but this states different!!!!!!!!

 

[hawk20]

Honest John is not being clear -or honest enough. The problem only affects cars from 2000 to 2003 build as MB said and only if they have the Valeo radiator. Of course some 2003 build cars were first registered in 2004 and that is why a few 2004 cars had the problem. You can always check the build date before buying (and whether it has a valeo radiator) to be safe.

As Hawk says post 04 are fine. You are right to look at 54 plate on as this effectively means that you should be buying something built into 04. Ideally a late 54 plate is best but if its an early 54 it may be wise to check the build date, just to make sure it isn't a late 03..
