Issues with ECO on E estate

[Red C220]

'12 ML63 so 5.5 V8 TT, what effect will stop start have on the turbos?

I'm not sure it would effect them at all, the turbos won't be operating at tick over would they?

Btw, fuel economy is amazing. I recently did a 2,200km trip and used less than 3 tanks. Left home on a full tank (90L, $105 CDN) and had to fill up again after 8 hrs. We went 850km on a single tank, I was so impressed. ...and that was hitting 185km/h on some straight stretches.... New vehicle too...only 2,500km on the clock

That's about 27mpg (UK gallons) assuming 850km was 90 litres of fuel.

I had an ML300 cdi Sport that would average 29mpg. So your figures a absolutely marvelous.

I imagine day to day driving though is closer to 15 - 18 mpg.

Lots of reasons for it to to catch you out.
Mine wasn't working yesterday. Turned out that I had turned the airflow to the screen (aircon off) and this also disables it :/

Steaming the windows up were you Ted?

I wish. Just the relative humidity and my stinginess in not cooling the air first to remove the moisture.

Yup, used almost the full tank, but there was probably an 1/8 left when we filled up again. Could have gone probably another 30-50km but couldn't chance it when driving between cities on a road trip.

15-18 sounds about right for the city but it's too early to tell since we don't have enough mileage on it yet.
...and the Renntech tune I threw on it is not helping me keep the ECO mode activated! Huge difference in power though.

There's logic in both - could be to do with battery charge (short journeys) or internal temp deviation (a/c).

Thanks. I took it for a short 15m trip yesterday and, again, the system worked perfectly fine with A/C full on. after 1,800m on the clock, the problem seems now to have been resolved... Strange really!

I'm not sure if it helps but there was a thread a few months ago which suggested a recent batch fault with one of the battery sensors on the W204 so may be relevant if they use the same parts.

Interesting. I will check with my local dealer.

Mine went in for that - but I was finding extended periods of failure - sometimes 2-3 days at a time.

Battery temp sensor is a known issue to Mercedes Technical but it would cause a bigger drop out.
