Just registered so greetings to everyone.

I was driving last night and everything was normal as always, but at one point the car lost it's power and did not accelerate well. Also I've got a message with thermometer (assuming overheating).
So I've stopped and shut off the engine. Started the engine and got check engine light.
Then I had to drive another ~50 km and sometimes can barely accelerate to 50 km/hour. I was watching temperature and it was between 80 C and 90-95 C.
Also I've noticed that after accelerating to over 60 km/hour power comes back (not to the full extent, but enough so I can drive).

So this morning I checked the coolant level and it was below, so I added about 0.5 - 0.7 liters of coolant. I've also noticed fluid (assuming it's coolant) on top of fuel filer! Also I've remembered that yesterday while driving I was getting condensation on the windshield.
I've connected a computer and got tons of errors.
Below are some of them:
129700 The diesel particulate filter is defective.
100D00 The lower limit value of component B2/6 (Left hot film mass air flow sensor) has been reached.
100E00 The lower limit value of component B2/7 (Right hot film mass air flow sensor) has been reached.
101500 The lower limit value of component B2/6 (Left hot film mass air flow sensor) has been reached.
101600 The lower limit value of component B2/7 (Right hot film mass air flow sensor) has been reached.
105700 Component Y27/9 (Left EGR positioner) has Short circuit to ground.
10B900 Component B16/15 (Temperature sensor upstream of SCR catalytic converter) has a plausibility error.
10C200 The control line to component M4/7 (Engine and AC electric suction fan with integrated control) has Short circuit to ground.
113D00 The heater for component G3/2 (Oxygen sensor upstream of catalytic converter) has a short circuit to positive.
11F100 The lower limit value of component B2/6b1 (Left intake air temperature sensor) was dropped below/not reached.

This leads me to believe there's some kind of coolant leak that got all these sensors shorted. Also I've remembered that while I was driving yesterday my iPhone was arbitrarily disconnecting and reconnecting over Bluetooth (which never happened before).

Any advice where I should start looking or anyone has experienced the same or similar issue?


Thanks a lot in advance!

P.S. I've got full STARS report if that's of any help.
