E400, 2015, Cabriolet

[M80]

I'm not sure I'm in the right area so feel free to move this.

Daughters fella is looking at the above. Based in London, so reasonable to assume most driving will be there.
It's listed as the 3.5 litre petrol, which sounds right enough.
Listed as Euro 6, I didn't think the petrol euro rating had got that far.
It's listed as AMG line, I'm assuming that isn't a true AMG hand built engine. More a mo mo that has some AMG kit stuck on.
There are obvious considerations with the 19" diamond cut wheels.

Hoping to fore warn, is this engine a known good one?
I assume it has the 7 speed auto, I'm trying to see if that's 7g+.
The rear seats look to be reasonably spacious, are they?

All thoughts appreciated.

Yes, it certainly has my 14 plate BMW 435i is EU6

I’d no idea when I bought it that it would comply with ULEZ but no complaints I’m sure the emissions regs will catch up with us all in the end - who said big petrol engines were dinosaurs lol

The C207/A207 E400 has the mercedes M276 engine which came as 3.0 litre or 3.5 litre version depending on the build date. They both had the same power output of, I think, 333hp. It's a superb engine. Very smooth and certainly quick enough for most people's needs. I ran a C207 E400 coupe for 4 trouble free years.

You're right, it's not an AMG engine. MB never made an AMG version of the C207/A207.

It will be 9 G-Tronic

The E400 was on my list in 2018 but they were a bit new and pricey for me at the time and I fancied trying ‘The ultimate driving experience’ brand so opted for an IL6 435i. I’m now looking at the M276 in twin-turbo guise E43 AMG engine and will hopefully find one in 2023 once the secondhand prices come down from the ridiculous trajectory they are currently on. I think the M276 is a better option than the M256 being much simpler in design and consequently a better long term proposition

 

[M80]

Thanks for the responses. I think the info I've passed on is useful.
He is planning to view on Saturday, but I reckon with a week of consideration and dreaming if the colour of its curtains appeal he will buy.

I've more info on the car.
It's 7 speed, and the VIN gives no indication of 7g+, 722904 06 406634 is the transmission. I didn't have issue when I owned a 7g, in truth I'm happy with the 5g. What real world advantage has the 7g+ got?

Is the M276 duplex chain? This has stop / start. Should that be a concern re a stretchy chain?

It has a 5 / 5.5 Comand. What integration with an iPhone is possible. Does the BT have an audio function for example?

Is the rear seat space silly small? Photo's don't look so bad.

For a 3.5 litre petrol the official consumption figures are impressive. Real life wouldn't be a good I imagine, but I don't think you buy these with that as a priority anyway.
0-62mph in 5.3 seconds is also impressive.
As said, as a smooth and quiet engine this is a car that can give a lot of pleasure, it certainly isn't shy of toys.

Answering from my e400 2016 model....

1. 7g+ signifies stop start (and as this one has s/s it's a plus box)

2. No idea on chain query, but see below link though.

Mercedes Benz M276 Petrol Engine Service Manuals .pdf

Mercedes Benz M276 Engine Introduction Into Service Workshop Service and Repair Manual Versions M-276 DE35, DE30, DELA30-(DE30AL), DELA35-(DE35AL)

mbmanuals.com

It is Euro 6 (which is no different to EU5 on petrols afaik)

3. MPG at 70mph, two up was 40.9mpg on an 80 mile run last week and 44.8mpg on a 250 trip from the NW to Southampton last month. Round town, high 20's....

4. Rear seats and space are fine for adults (access is the challenge despite big doors on the coupe)
Boot is very decent

5. ref Command, it will have full BT and may also have apple car play and/or Android auto - I have only the former - check the build sheet via a vin decoder
Live traffic via the good MB sat Nav is £250 for 3 years (I got an old iPhone, a PAYG data sim and use Waze via car play though, despite being an Android user)

6. 5 seconds is possible with good tyres and traction
Stage one remap takes the 3.5v6 tt to 420bhp and 630NM and close on 4 seconds....
It's under 'blown' to maintain the performance gap to the C43 and even the C63 in the real world after they dropped the 3L for the last year or so of the coupe production but better mpg maybe the reason (don't definitely know why they did, but am happy that they did)

 

[LostKiwi]

7G+ doesn't signify stop start - my 251 is 7G+ with no dreaded stop start. 7G+ has the code 03 or higher after the first 6 digits of the gearbox.
Mine for example is 722903 03 xxxxxx

I believe there were some internal changes and software changes to make the box smoother.

 

[fabes]

Oh, I could have sworn, but happy to be corrected.
Mine is deffo a 7G (not 9G) and a plus

 

[M80]

Thanks both.
For different reasons you seem to conclude this is 7g+.

I count at least 4 simplex chains. Not all will be under the same shock forces at start up, and at least they're all at the front. Being rwd I'm assuming the engine isn't transverse.

Rear seats, tick,
boot space is a surprise, but tick.

I don't know the guys inclination for power gains, it seems pretty good as stock to me. I'll pass on the info though.

I'm not seeing anything on the VIN decode that indicates iPhone or Android compatibility.

For 40 quids he has reserved the mo mo. This refunded if he doesn't buy, apparently. I don't see point in taking the 40 quids, but not to worry.

I reckon I'll be meeting the chap and his new toy soon enough.

 

[malcolm E53 AMG]

As I recall the introduction of stop/start to cars with 7+gtronic boxes required the fitting of an external oil pump to the gearbox to maintain operating pressure while the engine was stopped

 

[M80]

The chap picked up an E400 yesterday.
Loads o toys, looks v good.
There is some minor kerb damage to 1 diamond cut wheel, any suggestion where around London could dress that up for him?

This one has the 3 litre 276 engine.
7 speed definitely, with + I'm not sure, but it being a 722904 05 it seems likely.

I've not seen evidence of an ATF service, so at just on 60k miles I would say that's a must.
It seems Halfords were the last to give it an oil change, and a flippin' flush ffs. While only 3k miles ago I personally would get that stuff out and fill with a known good brand, and filter come to that.

I've passed Alex Foti's details as I would trust good service there.

I've passed details of Comand Online, but it has the UCI iPhone interface so might not need upgrades.

Thanks for the input thus far.

 

[Capra]

Would be great to see some photos. This was something that I looked at taking on 2 years ago. But decided against. Sounds like a great car. If he's not happy about the headset, there are loads of Android conversion for under £300 available.

Is this the twin turbo version of the M276 or the naturally aspirated? I would imagine it isn’t turbocharged but very interested in his opinion of the engine

As far as I know none are normally aspirated and are all twin turbo. They're only 3 V6's. I updated this as it was only the early ones that were 3.5.

Hmmm… you’ve got me thinking now looks like I need to do more research as there are about 3 or 4 versions of the M276 engine I do know the E43 has the twin turbo version which is a very neat set-up

He may consider this to be personal,
so I'll allow him to exercise his choice to join and post piccies if he wishes.

M002 Engines with EXH. turbo,

no mention of twin turbo just increased performance.
A previous owner has fitted a tuning chip that I imagine will have little benefit.

They had M276 didn't they, with different specs over time, I'm sure the 2015 E400spec for these was 2x turbo, 2x intercooler in the 3ltr version.

 

[fabes]

Later E400 had the original M276 3.5L capacity put back in it (fettled for Euro 6), with the IHI twin turbo retained, albeit dialled back to under 10 psi compared to 26 psi for the 3L version of the M276 (if the internet is to be believed)

The non turbo 3.5L M276 was what the E350 that I had, had.

The dial back on the 3.5 E400 was to maintain the performance gap to the AMG 43 models which ran boost up to make over 100bhp on the base n/a engine.
Applying the same map principles to the 3.5L creates a similar hike...
