Winter problem

[jam1es38]

I have a 2013 E220CDI (w212)?
Last year between October and April this year my car has NOT liked starting.
YES, the problem is back.
I have changed BOTH batteries recently.
On the first starting of the day I put key into ignition and turn sometimes NOTHING happens.
So I pump the brake pedal, sometimes this will let the starter work.
Sometimes with my foot on brake pedal again Nothing happens.
I remove key and rotate 180 degrees and try ignition again, sometimes this helps.
After it starts the fault message below will show
After removing all faults at a garage last night with 40 miles driven the ECO light stayed yellow.
My car is used as a taxi and has 181,000 miles on the clock

Sounds like you have a less than optimal battery. Did you fit the correct size and technology?

Yes the aux battery was sold by Listers in Humber after checking it was correct size.
Maybe i should try and get a more powerful main (big) battery ?

Might be glow plugs or glow plug relay ?

The GP light comes back on and stays on in that case.

Re the battery OP, check the voltage before start with a voltmeter in themorbing and report back.

Did you get a decent main battery - Varta for eg or MB own and the right spec, there is no point in getting an over spec battery for the car.

Glow plugs changed last week on a Mercedes service

Relay then ?

I'd check the alternator. The brushes could be worn at that mileage and it may not be charging the battery properly.
