E90 thermostat advice needed

Howsit Gents

My e90 330d (Pre LCI) seems to be running a bit too cool for my liking on the high way, this morning on my way to work using a bluetooth OBDII port adapter and the torque app it showed my coolant temperature ranging in the low 60°C at 120km/h. I'm no expert but i think thats a bit low and suspect its the Thermostat that could be faulty. When idling it sits around 90°C - 98°C and then the fan kicks in, and when driving in town it sits between 70°C - 80°C.

I have changed the Waterpump and EGR Thermostat on Sunday as the waterpump decided it had enough and the EGR Stat just followed, so we can rule those two out :hammerhead:

I got pricing from BMW and its R1297 for the thermostat and from GW its R830 for a Behr/Meyle

Now the question is which should I go for?

GW part is fine.

Replaced my both thermostats a couple months back with the same symptoms, Bought Behr from GW and now issues. My EGR was faulty causing the issue but i replaced both. So kept to OEM main thermostat as a backup

Thanks @Stompie for the reply but just a bit confused, "Bought Behr from GW and now issues." did you mean no issues or as in it started giving you issues?

I suspect he meant no issues

Thanks @M135i I was hoping he actually meant that as it saves a bit of Mandela's going with the GW part due to BMW charging an arm for coolant as well. :dunnoanymore:

 

[Stompie]

No issues, sorry for that

So just to update this thread in case anybody with an e90 wanted to also use the GW Thermostat (Behr by Meyle), Paid R830 and installed it my self, its a quick DIY, the EGR cooler just needs to come off and you can get to the thermostat takes less than an hour to change.

Its been about a month now and the new thermostat is working great, using the torque app with a bluetooth obd adapter and the coolant temp sits around 90°C - 93°C on the highway during the day as well as night, Town driving temps sit in the same range, also the car warms up to operating temperature much quicker.

So far happy with the Behr Thermostat I will update this thread should I encounter any issues with it. :thumbs:

Thanks for the feedback. Glad its sorted:thumbs:

I would also just go for the Behr thermostat,because as far as I know the OEM one is a rebranded Behr one too and the quality is definitely decent.

Where did you get the OBD reader from? I am looking at getting one for my 330d too.
