Than (what tool) have been read 8 port error?
led or computer-based scanner?

I think this "slow codes" (led blinks), then:
13 035 with TWC
Lambda control is at rich stop, mixture too lean
Air ingress, fuel injection valves
Diaphragm pressure regulator

13 036 with TWC
Lambda control is at lean stop, mixture too rich
Air ingress, fuel injection valves
Diaphragm pressure regulator

37 088 with automatic transmission
Upshift delay switchover valve (Y3/3) - open circuit/short circuit

Source Error Codes - Mercedes WIS document


The fact that your car can not be code 013 (if the scanner reading) since HFM ECU does not control the throttle itself, and therefore can not see a problem with his potentiometers ....

the best solution - connect the scanner and drive the car to the problem manifested itself when the diagnostic session, and then try to find the problem in the data (logs), which will bring together the scanner.

PS: you have Throttle angle = 0 on idle speed (log data from febrary 2014)
try this:
1. engine is warm (coolant>80*)
2. set ignition ON and wait > 2 minutes
3. run engine.
This adapt throttle on your engine.
