Can't say anything about FE during the last month other than "It sucks!" I'm lucky if I'm below 5.0 l/100km when I pull back into the driveway. It's because of a combination of the car being more or less frozen (pull the hand brake and it sticks for 10km), snow tires, snow everywhere, and the geometry (toe) of my front wheels being off. I've got to get the latter fixed before a longer trip comes up...

After the engine warms up I open the IC's part of the lower grille block, and that shouldn't contaminate the radiator with cold air now that the two are fenced off. But the AIT sensor is before the turbo and IC, and I wonder how the ECU handles that? I mean, does the intercooler undo what the turbo did, or does the ECU see 17° pre-turbo, but the air that makes it to manifold is 5°C, or maybe 25°C? The 1.6HDIs with an
air doser/IC by-pass valve have a second temperature sensor, post IC, so that may help the ECU control combustion more efficiently. All the more reason to find and install one, but since my ECU wasn't programmed for one, then it probably won't be able to use/control it. Swapping an ECU from an engine with the air doser won't work, since those engines also have a DPF, and knowing how much trouble having a DPF is (not counting cleaner emissions, of course), I can't imagine what kind of thrills the ECU will sponsor if it can't find the DPF
If I do find a cheap working air doser, then I'll fool around with it manually. Then maybe a newer ECU and a DPF emulator? Let's not get carried away...
EDIT: Maybe a
new, simpler air intake?
