'06 I6 CDI vs '07 V6 CDI-Which Is Better? - PeachParts Mercedes-Benz Forum

Gilles Kay · #1 06-06-2009, 12:18 PM

I'm considering buying either an '06 E320 CDI or an '07 E320 CDI. The '06 has the inline 6 and the '07 the new Bluetec V-6. I would certainly appreciate any comments regarding the differences in mileage/smoothness/reliability/experiences between these two engines. Also, does the '06 CDI have the 7 speed automatic transmission? I believe the '07 CDI comes with the 7 speed trans. THANKS for all your input!!!

Inline is always better.

X2 - that's what I have always found in diesels in general, but not familular with either of those . . .

The 06 has the 5spd 722.6 trans and SBC brake system. MB has warrantied SBC for 10 yrs from date put in service due to problems. Proven I6 CDI engine and trans.

The 07 should have the 7spd 722.9 trans and SBC was dropped. New V6 engine design; not AdBlue. Many internal components designed to be repalced in pairs. Dot 9 trans had some early issues (04?) but seems reliable now.

I've been looking mainly at 06's myself, although would take an 07 if the right deal came along. No exprience concerning the driving differences.

I've driven both. Both are very smooth, but the V6 is quieter. The I6 has quite a bit of diesel injection rattle at around 1500RPM - it is noisier than the old OM606, for example. The V6 is almost completely silent at all RPM and throttle settings - noone would ever guess it is diesel. Power and fuel economy are about the same.

No idea whether one is more reliable than the other. Haven't seen any discussion here of problems on either. Personally, I'd purchase whichever one I found in my favorite color, or had the lowest mileage, or whatever it is that turns your crank on a used car.

Is it practical to upgrade the 06 SBC brake system to the 07 design? What would be involved?

Somehow i dont think swapping those trannies would be a straight forward job at all. There is a awful lot of electronics nowadays to these babies.

I don't figure they'd put the "BLUETEC" label on the trunk badge of truth if it didn't have urea injection. And so there's definitely E320 bluetecs in the states.

Since I'm not a fan of "so quiet you can't tell it's a diesel" and not a fan of urea injection and not a fan of any additional electronic complications, I'd go for the CDI instead of the newer model every time. But that's just me.

I tend to suspect older models are almost in every case more long-term "million miles" capable than the next replacement will be. Another point in favor of the older design to me but others have complete confidence in the new stuff.

i couldn't agree more, plus you can get a cdi with 50,000 miles or so dirt cheap

Thanks for all the input, everybody. I really didn't mean to start a major argument. I appreciate all the positive input. I will discuss all this with my MBZ mechanic. As always, THEY are the ones who see these cars on a frequent basis and know the good and bad.

Read again, the question is about updating the brake system from the troublesome SBC to a non SBC system.

TMAllison · #12 06-07-2009, 12:20 PM

For like the 5th time, there are NO E320 Bluetec's in the USA with AdBlue (urea injection) up through the 09 model year. Zip, Nada, Nein.

That does not mean there aren't E320 Bluetecs WITHOUT AdBlue available.

There are GL, ML and R320 Bluetecs WITH AdBlue in the US that have been avail for a year or two. NO E's.

I would guess that getting rid of SBC would be a hardware and software nightmare.

I hate to say this but you sir are retarded. Go ask the dealer thats nearest to you

the late 07-08-09 E320 Blutec DOES have Adblue urea injection i know this because 1. i have a brain. and 2. my buddy has a 2008 E320 Bluetec and when the dealer services it under warranty they fill the car with urea!!!!!!!!!

face it your wrong
