P2172 Diagnostic trouble code (DTC) P2108 stands for "Throttle Actuator Control Module Performance

P2106 The P2106 OBD-II trouble code is one of number of possible codes that indicates that the Powertrain Control Module (PCM) has detected a malfunction and is limiting the operation of the Throttle Actuator Control System

P0122 throttle/pedal position sensor/switch A circuit low input
P0223 throttle/pedal position sensor/switch B circuit high input
P2101 throttle actuator ctrl motor circuit rang/perf
P2104 throttle actuator ctrl sys-forced idle
P2110 throttle actuator ctrl sys-forced limited rpm

Here is the meaning of the codes hope this helps

Here's code P2100.Here's code P2108.
Throttle Actuator Control Module Performance (Motor For Intake Flap V157 Malfunction)

p2108 is- TAC module performance, From what I have read cleaning is usually a temporary fix and replacing the throttle body is the permanent fix.. ( throttle actuator control ). Try cleaning your TB before you replace it. good-day !

Looking up that code by number lists it as this P2112 DODGE Throttle Actuator Ctrl Mod Processor,, I know on some VW's the coding is different,, so I'll try and see if that code is the same for your car

For VW Golf TDI:
If the car goes in "limp mode"!!!
After scan the EDC-15P engine control module with a VAG-COM or BOSCH KTS diagnostic tool connected to the data link connector of the car, (placed on central console under A/C controls behind a plastic cover), you will find this: Fault code: P1557-Turbo Boost pressure control exceeded
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.
3. This is the most difficult work. The problem is that the soot particles deposits inside the turbocharger plugging the variable nozzle geometry mechanism = adjustable vanes of the turbine. If the turbocharger actuator is not able to adjust the turbine vanes the charge air pressure increase too much and ECM (engine control module) go in "limp mode" = engine protection software. As a result the "limp mode" engine still running until you turn the engine off (ignition switch off) and back on when the "limp mode" is deactivated, but the fault still remain in ECM memory!
4. You must be able to extract the turbo from the engine and then to disassemble the turbocharger, clean inside adjustable vanes mechanism and refit all.

Hello..
Code 21: Is an oxygen sensor Code 54: Is a crank positioning sensor.
Hope this helps!

try cleaning the throttle body with top end engine cleaner, if it lags you have a problem.

We think it could be the engine management system - would recommend going to a reputable garage for it to be reprogrammed.
