    Or get a load test carried out on it. Most places that sell batteries should have one and offer the service for free.

    Thanks all. So I had it in at the dealers yesterday, they redid the wiring around the battery and replaced the battery, cost a small fortune. Apparently the wiring was all messed up and the battery around the connectors was all burned. But the worst part is it only solved the problem partly, now the engine behaves normally with high electrical load BUT, I still have problems with the outbox when the CC is on, basically when stopped in D, there's a horrible grind sound coming out of it, and the fuel consumption is up by about 10-15%.
    Everything is fine in P.
    I should probably repost this in another thread at this point.

    That's exactly how I turn it of, by switching blower to 0. I've seen on YouTube somewhere the guy turning it off by pressing the middle dial, but that doesn't seem to work for me.

    If you can't push middle knob in it's need fixing. There is a how to on youtube - you will need soldering gun to do it. Try to press it really hard and cc menu should be visible.

    When you turn knob on 0 air compressor is still on, just fan is not working. That's mean engine still is using more fuel and power will drop a bit.

    I would say that air compressor is on it's last leg (seized - or getting there)

    Yeah, I can still get to the CC menu, by holding it down for bit. When I turn it to 0 though the fuel consumption goes way down, not sure if CC is still on or not.
    The compressor is probably on its way out though. I wonder if it could be causing problems with the outbox though. Although tbh, at this point I'm starting to get my fill of trying to fix this car, just for the next thing to give out.

    Letting those who try to help know which cabin air system you have would help, Lupus might be familiar with climate control i only know about the automatic climate control and the manual one so without picking up the hand book to find out how that third system works i wouldn't know. All i know is its something to do with AC so turn that off not the cabin air system.
