335d operating temperature

Ok so does anybody know the BMW spec for operating water temperature?

I h a ve just changed my egr thermostat and whilst temp goes up quicker now im not sure it is reaching target.

If anyone knows it will be handy in trying to determine if I need tackle the main 'stat

Cheers
Dan

Excellent thank you very much.

Looks like I need to do the main stat.

Annoying.

Interesting input.

I haven't seen mine hit 90 yet. High 80s in traffic but when on the motor way it sits in the 70s.

I haven't seen any particular change in fuel consumption either, still sitting around 500 per tank.

That's pretty good mileage for a tank! I get around 350-400. You must do a fair few motorway miles?

How do you check the temp? I know there are posts but even with searching I couldn't find it (no doubt my stupidity will be highlighted.....)

The coolant temp is menu 07.00. That link lists some other useful menus as well, such as battery voltage.

You probably won't see any difference in fuel economy . The only thing you will see in time is a little yellow light on the dash that says DPF is shagged.

DPF regens require a minimum set temperature ( not seen an actual figure as yet but certainly higher than 80c whilst running at +40 mph.[past experience]) . When they go to regen it causes the temp to go to circa 96C .. if you've never seen 94,95,96 whilst cruising ... then your DPF hasn't seen a regen. for the cost of having both the EGR and Main stat changed it's a no brainer.

my previous one ran at 86 when the egr stat went it dropped to around 72 along with a loss of about 5mpg. the temp would sometimes rise to 90-100 on a steep hill and seemed in general pretty erratic.

You must do a lot of 'urban' driving, I do a mix of urban and motorway and my last tank got me to just under 550 miles (although I think I was running on fumes at that point!)

An average tank for me is anywhere between 470-520 miles.

Finally got round to checking my temp, only reached 78. I'd guess that's a problem then!

Today I decided to change my main thermostat and to be honest is wasn't even that difficult.

I should really have done a how to/DIY guide but I wanted it done as soon as I could.

Took her for a spin afterwards and the temperature now sits at 92/93c which is awesome.

Where do you guys buy them stats from? Are these on the carparts4less.co.uk any good? If yes which ones should I get - cheaper or more expensive ones?
Cheers!

I'd just get BMW ones.

The temp should never really drop below 88 once hot. Cold temperature and AC can make it seem like something's wrong but probably isn't as long as it does hit 88 and not drop much after.

I replaced both thermostat, purchased from ECP and went for the more expensive. The EGR thermostat was made by the same company and just had BMW scratched off for licensing purposes. However the main stat was not an "OE" from the same manufacturer but will be fine all the same.

BMW chat bullshit. Don't trust them. The main stat is rated much higher than 77c. 88c i think.

Is the operating temperature constant or does it drop if you put your foot down, mine a 325d sits at about 86/87 then drops to 81 then goes back up?

There's a possible drop but the thermostats should shut at 88c, meaning there's no effective cooling happening. The heater is still drawing heat from the engine so it's worth doing the test with the AC off, temp set to 16 and fans off, as having the heating AC on could be dropping it a few degrees.

It's a lot easier to test in summer than winter.
