read about breaking in new diesel engine - author repeatedly referred to warming up engine first. how do i know when i hit that sweet spot of proper warmed up-ness? i obsessively want to make sure i get it right and really know, not assume.

Well all you can see is the temp gauge to see if its warm enough unless you run with VCDS connected to read actual temperatures measured by the ecu?

I would also wait until the oil temperature is warm. Five minutes after the water temp is in the middle I would consider the car as warm as it's going to get. The oil can take a little bit longer than the coolant.

i just didn't know where on the gauge was considered optimum...so when i take off in the morning, take it easy until when? in the old days, warm up meant idle and i know that is not good. not blonde, just honestly ignorant. a little embarrassed about it, too.

i will examine the gauge today and see where the middle is + ask at dealer when i pick up - just getting today!

Congrats! Make sure to carefully look over the car don't assume that the dealer has inspected it well.

Well the US models for normal temperature is 190F straight up on the gauge isn't it?

yep, duh, figured it out. i can be overly literal and unnecessarily persnickety.
