My 2006 e350 mercedes heater dont get warm

Unlikely to be smoke, it is steam. Your leak will be in the heater matrix up behind the dash. In one of the links it says to check the freeze plugs on the back of the engine.

check that the heater controls are turning on the coolant tap for the heater core
check the heater core is not blocked

From what I found it should be 40 amps. Is the original fuse missing? If not, replace with what is already there but it shouldn't be less than 30 amps as these motors draw quite a load.

Hi,you are looking at a fully sinfetic oil,ask at a main deelers they will put you in the right direction,dont just go to your local shop they might sell you eneything,get the propper oil for your car.

thats because the electrical system is using more power than the alternator supplies at idle so the ECU increases idle so that all electrical systems i.e fuel delivery etc have enough power supplied absolutely normal

sounds like you have ablooked heater core. start up the car let it warm up check your heater hoses both of them should be hot if not you have a blockage . take both hoses off and back flush them

Not completely sure what symptoms are but you may have a partially plugged heater core. A reverse flush through the heater core may do the trick. There will be two hoses going to the heater core, one in and one out. Sometimes these heater cores are easy to replace, sometimes it's a major job. I am not familiar with the e350. There is a danger of creating a leak in a reverse flush if rust or whatever is sealing a leak.

LOW ON COOLANT!!
