Help: Temperature Gauge Above 80?

[Bobby Dazzler]

My e220 estate engine temperature guage never goes above the 60% mark and never below the 50% line.....

Is that OK or too low please??

Too low. A new thermostat ought to sort it.

Thanks,

Now THIS is strange...

Left her with rear down for a few days, no option I assumed.....

Then yesterday started her up and she raised to the higher normal drive position!!

I've no idea if Mercedes self regenerate like in the movie Christine!!

HOPE SO!!

THE Coolant to issue.....

When I started her this morning I did so with the expansion tank CAP off. Within a few minutes loads of bubbles came out of the expansion tank
...

IS this an air lock as I suspected OR am I just getting rather desperate here please??

The question I'd ask is , does the temperature gauge show around 85c when fully up to temperature after expelling the air bubbles?
If not, it requires a new thermostat, The new ones open at a slightly higher temperature of around 87-90c
