A-class W176 1.8 CDI coolant temperature

[JiSingh1]

Hi guys,

can anyone tell me how long their car takes to get up to the roughly 90° degree coolant mark in a W176 Diesel?

My mum has the 2013 W176 A-Class A180 CDI.

She told her stop start stopped working a while ago, i thought this was the auxiliary battery but was no error about it on the dash.
We just left it and put it down to her driving the car about once a week roughly.

However today I was with her and after a combined 25 minutes roughly of driving and idling, the coolant temperature gauge was around 60/70.

I feel like it should have been warmed up by that point and that it is taking too long? Can anyone tell me if this is normal or not?

Got no errors on dash. In my little Polo, stop start only works after certain conditions are met, like economy and temperature.

Thank you
J

Hello and welcome,

8-10 minutes depending upon ambient air and engine usage, replace the thermostat.

You won’t necessarily get any dash warnings for a battery issue. Measure it at rest (engine off) preferably first thing in the morning. Anything less than 12.4v and the battery needs charging/replacing.

As above, replace the thermostat. You'll likely find the fuel economy better as a result !

Yep thermostat. I had the same problem recently. Changing the thermostat solved the problem.

Would have thought there'd be a P0128 code or something if the thermostat had a problem.

The battery did die a few weeks ago and had to be jump started. Will get my multimeter to check. So just put it on 20V DC and just check the voltage, simple as, right?

Yes
