Mercedes W220 S-class fault codes

[jawnuolis]

Hi today I had Mercedes S-class there are some faults from injection are this correct?
P1403 Exhaust gas recirculation (EGR) system - malfuncion. Probable Cause: wiring, connectors, hoses, intake leak, EGR solenoid, MAF sensor.
P1470 Turbocharger (TC) boost presure - pressure too low/high. Probable cause: wiring, connectors,hoses, turbocharger (TC) wastegate regulating valve.
P0100 Mass airflow (MAF) sensor/Volume air flow (VAF) sensor - circuit malfunction. Probable cause: Wiring, MAF/VAF sensor, ECM.
P2204 Nitrogen oxides (NOx) sensor, bank 1 - intermitten input. Probable cause: wiring, poor connection, NOx sensor.
P1636 Engine coolant blower motor control module - malfunction. Probable cause: wiring, connectors, engine coolant blower motor, ECM.
P1481 Glow plug(s) - defective. Probable cause: wiring, connectors, glow plug(s), ECM.

also there was fault in other modules but I cant found description
ESP:
C1504 signal eror/ signal variation, signal missing.
electronic ignition switch:
B1010 : The supply Voltage of the control unit is too low (under voltage)

suspension:
C1026
C1122 AIRmatic: fault in component B24/4 (acceler. sensor)
C1517
C1013 terminal 30 low voltage
C1402
transmission:
P2502 The gear is implausible or the transmission is slipping
P2503 The gear comparison is negative or the target gear is not reached.
P220A P220A - Y3/6N2-Y3/6N3 speed compare implausible
P2600 circuit voltage too low

thanks for any help in advantage

What engine is this? Cylinder, capacity, diesel, petrol, model year? What did you use to read these codes?
I doubt that the descriptions (except for P0100) are all correct. Mercedes had a habit of using totally different descriptions and meanings.

After diagnosis, did you clear dtcs and which ones remained ? Thats where we start the analysis from.

it is 2002 S320 3.2 CDI straight 6 diesel used Abritus72 AVDI

[oldford]

I doubt if P2204 is correct. Don't think these diesels have a NOX-sensor. But I could be wrong. The others from the engine make sense.
When so many systems fail (Egr, Boost, Glow plugs, Cooling fans) I suspect you're missing 1 or more 12 volt feeds. Check all relays and fuses.

maybe P2204 is incorrect after googling I found more.....
P2204 External quantity control by ETC CAN reception timeout
P2204 External quantity control by ETC ENGINE STOP
P2204 External quantity control by ETC Not all CAN messages have been received.
P2204 External quantity control by ETC Read fault memory of control unit N15/3 (ETC control module).
P2204 External quantity control by ETC Read fault memory of control unit Transmission control.
P2204 External quantity control by ETC Request from control module N15/3 (ETC control module) is implausible.
P2204 External quantity control by ETC The CAN message is implausible.
P2204 External quantity control by ETC Torque request from control module N15/3 (ETC control module) is faulty.

and found more descriptions for other faults edited in first post but I am really confused it is right descriptions or not

Pointless going through all that. As above clear everything and start again.

I am not about going through all that but generally about fault descriptions maybe somebody has something like attached document but for newer Mercedes vehicles?

[sogaro]

You want manual or you want solution?

[jawnuolis]

I want manual or some database with mercedes fault codes description for future. you know fault codes from tool without description are useless....

[sogaro]

with this you are good to go

[oldford]

Or have somebody with the right software read the codes.

it not so good..... European vehicles not covered.....

buy one autologic for mercedes......any and yes i do mean ANY problem you have with mercedes for codes etc they will help you and you can do what a benz dealer does......and you also can do performance tunes...and the best thing is that all these are legal.....
cheers mate......

hi, did you check vacum supply pipes (-0,7:-0,8 bar) and solenoids which controls EGR and TURBO
i think this faults are common about vacum
