Running in?

[steve333]

In eager anticipation of collecting my new w212 E350cdi sport saloon next week what are the running in procedures these days(i will read the owners handbook once collected but would like a few pointers in the meantime).

 

[mika]

restricted revs and throttle for first 1000 miles
or thereabouts

still allows plenty of scope

do what i did and go on a long trip straight away
i passed 1000 miles on the fourth day hehe!

Hope the person that put the 62 delivery miles on the clock observed that!-thanks for the info.

I think it is as much about running in the transmission as well.
No over zealous use of kickdown etc.

 

[mika]

everything in moderation , braking too

Not sure that 'running in' is much of an issue these days with modern cars. Add to that it's already got 62 miles on it and I think you are good to go, drive normally and you'll be fine.

If it were mine, I would certainly flex it through the rev range a few times once fully warmed up - maybe on the latter part of your journey returning home? You want to give it a fair prod of the throttle here and there to bed it in, let the rings seat properly etc.

You will have three years warranty too from MB if it's new, should easily show up any teething problems

Thanks for the heads up Will,3 years warranty always nice & peace of mind on a new car.....

The guidance in the manual is:

• Drive at varying vehicle speeds and engine speeds for the first 1,500 km
• Avoid overstraining the vehicle during this period, e.g. driving at full throttle
• Try to avoid depressing the accelerator pedal beyond the point of resistance (kickdown)
• The shift ranges 3, 2 or 1 should only be engaged when driving slowly, e.g. when driving in mountainous terrain
• After 1500 km, you may gradually accelerate the vehicle to full road and engine speeds

So, pretty much drive normally!

I picked up my new E350CDI from Sindelfingen and was told that it would be fine to enjoy the derestricted autobahn sections on my drive to Trier, which therefore was accomplished at a variety of speeds, including some sustained 100mph cruising and a couple of stints at around 125-130mph.

You need to avoid babying a new diesel engine too much as you can glaze the bores and rings and it will burn oil forever more. Don't be afraid to use the torque at lower rev's. At 20k miles my W212 uses not a drop of oil between annual services, so I must have got that bit right

Sounds good!-How have you found the 350/mpg?

 

[st4]

Just enjoy Steve.

Don't thrash when cold but don't just sit there at 50mph in top with the engine barely ticking over either to avoid glazing bores and rings. say at 50 and warm give it the welly to the NSL in 3rd. Enjoy the torque...

Ah the joys of flappy paddle changes

How have you found the 350/mpg?

Over 20,037 miles it's averaged 38.1mpg, with a tank best of 42.9mpg and a tank worst of 34.9mpg. These are all brim-to-brim measurements as the trip computer flatters the real consumption by approx 12%.

My daily commute is 23 miles each way on fast B-roads. The rest of the use is pretty mixed, but with very little congested town driving. During the really cold weather consumption is noticeably higher as the engine, transmission and diff oil take a l-o-n-g time to warm up fully.

I'm hoping for 35mpg & have a simular(6am light traffic 26 mile roundtrip)daily(currently get 22mpg).

 

[st13phil]

I'd say you'll probably average 35+ mpg overall taking into account summer and winter use, but don't be disheartened if you don't see that average during the winter months on your commute.

I reckon mine takes a good 10-12 miles to fully warm up at this time of year and at the 13-mile point in my journey the (optimistic) trip computer rarely says more than 33mpg. Come the summer and it's showing 42mpg or more at the same point in the journey.

Worst ways still sounds good to me,fuel/tax/insurance/tyres etc difference over the 10 years i hope to keep will almost pay for Half the car alone!

It's a diesel so drive it like you stole it otherwise the bores will glaze up.

Heavy load up steep hills does them a power of good.

The price i paid for it it feels like i already have

Always interested to learn something new! Is this characteristic particular to diesel engines?

Any engine driven on light load can glaze the bores as the rings need cylinder pressure to press them against the cylinder walls.

Diesel engines don't rev as high as petrol engines and the cylinder temperatures are not as high, so there is not really any need to hold back to save the rings from losing temper.

It will be my first diesel mb so only driven diesel vans(last 2 from new) & the mpg has gone up with mileage on both(noticeably after about 25k).
