Quote from Behr Germany about OE and Aftermarket thermostats
I received this email today via a Behr Hella rep here in the States. This email confirms that the Behr aftermarket and OE tstats are the exact same part:
Hi Andree,
the VW/Audi part no. 050 121 113 C does have an opening temperature of 87°C.
Our part no is the 1.180.87.302 (which we deliver to VW/AUDI) does also have an opening temperature of 87°C, so it`s absolutely the same part.
For the IAM we can also offer this part with an opening temperature 80°C , the part no would be 1.180.80.302, but we never offered this part with an higher opening temperature than 87°C.
I hope this helps you.
Mit freundlichen Grüßen / Best regards

thanks for that info, it is helpful>>>
but would it be possible to ask why there would be a variance in running temperatures on the cars if the parts are identical? The variance is around 10-12 deg Fahrenheit between the OE tstats and the Behr unit based on what i have seen.
Thank you again for pursuing the answer.....it is greatly appreciated.

FWIW I have your kit shipped in Oct 2007 installed in my 225
I believe I got the Behr. It was just before these reports started being posted. I did see the temp run one mark high at idle for the first few days, but it normalized and ever since has stayed steady at the center mark. I wonder if all of us have had a trapped bubble that caused this. Regardless, I have run 30 minute track sessions when it was close to 100F without problems after installing the new kit.

I understand your statement, but the scenario you >>>
depict is not an easy effort.
I will be changing my thermostat out in a few months from the recently installed Behr aftermarket to the OE Behr...prior to that installation i will run VAG logs and attempt to create that scenario, as that will likely be the closest possible example.
I want to be wrong on this...but i am merely stating what I have "seen" and read.
Again, thank you for looking into this and your continued support of the VAG community...

Cool. Are you logging coolant temp via signal to ECU or climate control?
has anyone verified these readings are from the same sensor? I would think it best to look at coolant temps in the engine via Vagcom.
I have a 1.8T transverse car but like you, I don't have a whole lotta extra time to swap tstats and my car weighs 2600 anyway so I don't know how valid that test would be.

i have done both in the past>>>
VAG will obviously give us an opportunity to look at the raw data and record it which is key....
I currently monitor the temps in my car via the HVAC and Scangauge which is an OBD aware device that pulls the data from the ECU. When i have compared those numbers, they are within 1 C at any time (the variances seem to be the time it takes to report the data, so more than likely they are from different sources).
I have however compared VAG to the HVAC and seen almost identical data that Scangauge reports.
I will try to capture data in the next couple of days via VAG and log it. As the current Behr aftermarket t-stat is a mere 2 weeks old, and the cooling system is clear of air pockets (as best as you can tell on those things) to try and get a baseline...
Prior to the swap i will do later, i will log via VAG again to compare for a time difference to insure there are no radical differences...
Then i will replace the t-stat....and repeat the process and see where it goes...
For the record, beyond scangauge, block 49c reports a 8 deg C delta on average from prior to the timing belt job. At one point on Friday, after a 15-20 mile drive (on the highway at normal speeds), i returned home to see Scangauge report 207 deg Fahrenheit at idle in my driveway...This was on a 24 deg F day...normally it would not be more than 198 deg F prior to the service...
All coolant is new...and the system is full...
I am more aware of specific temps than most as my cluster temperature gauge is broken...so i always use Scangauge and the HVAC controls to keep an eye on engine temps....
Look forward to clearing this up....
