No mine are different at times, like when I am stopped but are mostly the same when moving. This is going to kill you we don't really know what the Atemp is exactly but it seems to be the temp sensor in the DME and some other unknown inputs. First simple and free thing to do would be switch MAFS side for side. The air temp is taken from only the one on the left side. When the MAF is on the right it is not hooked up.
Do you have a dme fan error? Ebox fan error?

If your top seperator hoses are squishy, chances are so are the bottom ones. But ideally it's a thermostat out job to replace them. And it's important they are in good order.

I don't think the seperators themselves are baffeled, so you can clean them out with brake cleaner & compressed air. No need to replace as they are just hollow cones.

Part numbers are below:

VENT HOSE - ZYL. 1-4	11151406952
VENT HOSE - ZYL. 5-8	11151406953
RETURN HOSE - ZYL. 1-4	11151407344
RETURN HOSE - ZYL. 5-8	11151406902
RETURN HOSE	11151406900

I just bought thermostat temp. sensor (13621703993), will install it tomorrow, and if doesn't work, will switch MAFs. No errors except for AA.

Thanks, i think i'll just change all those hoses to be sure )

Sorry man I must have mislead you. I was trying to say check the flow of the air in the ebox fan setup. If you do not see codes there it is possible the boot fell off the fan and the fan is not blowing on the right spot or some other reason.

Thanks for the info, will check it!

Quick update. Just changed my temp sensor (13 62 1 703 993) and attempted to change after-cat O2 sensors. While trying to remove them, they broke, as apparently, they were never changed in all of 82k of my car's life

And when we tried to install the new ones, they didn't fit

So we installed plugs instead, since the old ones were broken. And what do you know? It now feels like my beast is 100hp more powerful! I don't know which of the two things i did exactly caused it, but i feel like it's temp sensor's fault, making the car think the engine is hotter then it really is. So i'd suggest to anybody to change it if you feel your beast is becoming kind of sluggish

It's only $25 btw.
