Hybrid Issue

[Puddler]

Hi all,
New to Mercedes and the forum. Recently purchased a 2015 300h 2.1diesel Sport Estate and have an issue with the hybrid.

Firstly, “coasting mode” (I’ve just learned this phrase) where the car engine drops in/out, is this switchable by accident? By this, when switching on the ignition, do you have to hold it in start position for so many seconds to request either on/off?

It seems that the coasting mode is having a hissy and switching in out periodically. For example, yesterday, it stayed on during 4 journeys, then this morning, it started to work and has now stopped again.

Before I start digging into garage hours, is there something I’m doing on start up that is engaging (or not) the hybrid coasting mode?

The gauges are working, I’m getting hybrid assistance when putting the pedal down but the engine is not switching into coast.

Any help is appreciated

Darren

Welcome to the forum

Was expecting a post from Lewis Hamilton - I think he's having similar challenges

I had a 2015 300h estate for 2 years and never heard of a coasting mode ?

Hi Rich
Example: when the hybrid motor kicks in without the engine running? Apologies- maybe I’ve learnt a rogue terminology?

It’s also known as gliding mode or sailing mode

Hi Darren
Sounds like normal behaviour for the hybrid tbh , weather conditions effect the characteristics of the car if it’s too cold it won’t use the electric motor if it’s too warm it won’t use it either, As for starting procedure if conditions are right the car won’t fire up on diesel but will allow you to move off in electric for a few meters then fire up if you want it to fire up in diesel no matter press and hold the button or key a few extra seconds and that will give you diesel start up.
The hybrid part is fully automatic there isn’t really any settings to swap battery to engine
