What are you testing? Something boosted? Should love the colder, denser air.

And my Flat Stanley moment. Covered in salt and grime from the drive yesterday but happily posing next to the high banks of Daytona.

I bet that makes okay numbers too, even without the FI.

All about the downforce. At 100MPH you could put this thing upside down on the ceiling and it would stick.

I did the ECS level 2 refresh a while ago, and reading this thread I start to regret I should have sticked to Genuine BMW for ET.

The coolant level is fine, no leak, level sensor is plugged in, but low level message...

ET is made by "Vaico".

Anyone have the same experience?

I remember reading a thread about ET sensor mechanism somewhere on this forum.

^OE is definitely safest for that "feel good" status of not having to worry about it. For cooling systems I stick to OE, Behr, or Wahler with good experiences. But YMMV. Never used Vaico specifically.

I avoid URO like the plague... says the man currently running a URO expansion tank. I was forced into it.

Well my 1095 mile test drive is complete.
All good with the Dorman parts. They got me there and back with no issue what-so-ever.
