I am severely screwed

Took my Jeep Compass 2007 CRD for a check up. The technician said the car is in great shape and I should be proud of how well I've kept my car.
Two days later I received a buck load of codes. Black smoke coming out of the exhaust, limp mode, no ABS, 4WD!, ESP BAS, Emergency breaks and so on.

Tried clearing the codes but they came right back. What did I do to cause the codes? I didn't use my car for two days after the technician gave me praise.
What in God's namn should I do? I've installed a new EGR for the underboost code but a hissing sound remains.

Clogged DPF maybe? No idea why my abs is dead. Can't see any pressure in my front wheels but I can see pressure in the rear.

Check the image for info. Help me out bois.

What did the technician do for this “check up” ?
I’ve seen this mass DTC type problem with failing batteries and dirty connections.

2007 CRD is a real PITA to diagnose. It is a mix of Jeep/Chrysler/Mitsubishi engineering mixed with Volkswagen PD engine. The engine lives its own life with only poor communication to the rest of the car. And Pumpe - Düse was not the reliablest option. The turbocharger is a part of exhaust manifold headers, not sold separately. Although the turbo is used in many VW group cars, variable geometry is on its own, So you can not just replace it with VW/Audi/Skoda/Seat. You have to buy the whole unit from garret or go reman (with mixed results)
Looking at your DTCs :
Underboost can be caused by VNT actuator or VNT sensor, vacuum solenoids, charge air pressure sensor, mass airflow sensor.... but also with a simple leak in IC hoses. These go under engine from back to front and are prone to crack. Also check the small vacuum hoses an harness for VNT actuator. Vacuum solenoids are mounted in front of air filter on right side, with bunch of wires and vacuum tubes.
Then wiring harness from ECU to injectors. This harness goes behind brake booster (where it tends to rub) and to the cyl. head cover (where it tends to crack from oil)
The PD injectors and the wires to them are under cover and submerged in oil. And it makes the insulation brittle

Headlamp and ABS issues - check the auxiliary fuse box under the right headlamp bellow battery. I do not know what they thought in the factory but putting a fuse box to the bottom of a fender well exposed to splash water is just dumb. Check this thoroughly for corroded terminals from both sides. The same goes for main fuse box under the hood. 2007 was a first model year of MK and the quality was really bad.

The other suspected is clockspring. But this should be done under recall warranty. It uses the same unit as JK and these are recalled w/o problems

Clock spring? it only controls the SRS Driver air bag and all steering wheel functions. When that goes out you will get a SRS code, you will have no horn, none of the buttons on the steering wheel will work. I been done this road so many times with our JK i gave up the POS. even though now i can get then FREE and have. They never fixed the issue they just give them away now in the USA, the part never changed. I have took them apart to see my self they did NOTHING. I have even been repaid for the part when I do it my self. But after having these break ever 2 years or less. I said coitus it. I dont run air bags now in the JK. and the steering wheel does one thing now only turns the jeep. full harness and better seats................

Now the clockspring is integral to steering angle sensor (SAS). When it fails, you have no ABS, ESP, ERM and other driving assistents. With respective lights on the dash

Checks physicals damage on the car, lights, horn, any codes, CO2 and NO emissions if the car doesn't reach up to certain standards the car is labeled unfit to drive and I am not allowed to operate the car until I repair the car.

Clockspring has been replaced with MOTAR parts 1 year ago when the airbag light came on and horn stopped working.
The horn works now and airbag light is off.
The battery was replaced with a new one 1 year ago also.

I'm suspecting a leak in of the intake hoses for the turbo and one or two failing ABS connectors or the whole fricking ABS thingy is broken.

Can't find the auxillary fuse box.. I can only find the main fusebox which I checked with a multimeter and everything was fine there.
Clockspring has been replaced.
The hissing sound makes me to believe that I have a leak in one of the intake hoses coming from the airfilter.

If you have a hissing sound, then deffinitely check for leaks in hcarge air circuit
If you have broken ABS connectors, repair/replace it. ABS acts as a sender for vehicle speed messages over the CAN bus network.
The vehicle speed is derrived from wheel speed sensors. This info is needed by PCM an TCM(if equipped) to work properly.

Definitely, is there a way to check if the ABS connectors are damaged? Like, checking resistance in ohm/voltage?

Connectors itself only visualy. Sensors and signals - witech, starscan , starmobile or any other scan tool capable to read abs ecu, or lab scope

For $99 a blue driver will read and erase all your modules and DTC codes. It’s a smart investment these days for any vehicle.
https://www.bluedriver.com/products/...iver-scan-tool

If a wheel speed sensor or wiring was defective, it would have caused a specific code for that wheel

There is a large multi pin connector near the fuse box that relays a lot of signals. I would check that connector out. I doubt all those things would fail at the same time, that’s why I suggested main battery powers and grounds

I am already using the Bluedriver tool but it only says that it lost communication with position A, I don't know what position is A.

My Bluedriver OBD II scanner says it's position A that's busted but I don't know which wheel is "A".

There is no such thing as "wheel A"

Code P0501 is a generic OBD code " Vehicle Speed Sensor “A” Range/Performance. This means there’s an erratic signal output coming from the VSS (vehicle speed sensor) to the ECM/TCM Your ABS module acts as a generator for VSS. It calculates this signal based on its own inputs and populates it over the network

You need a scanner capable to directly read ABS module live data and sensors. Not bussed inputs or generic OBD codes
