Throttle Actuation Potentiometer Signal 2 Range/Performance
P1568 Definition: Idle Speed Control Throttle Position mechanical Malfunction
These two codes are related to the same failed part and the very likely cause of this is a defective engine throttle body assembly, this is at the air intake to the engine where the throttle valve is, it is held on by 4 bolts and easy to replace, this is a common failure in this model.

    Yes the throttle body assembly needs to be replaced to correct these two codes. I would suggest you try and find a used one if possible the part is very expensive

    You must complete I believe 3 drive cycles, if the PCM doesn't sense any further problems then the light will go out, you can also turn the light off with a scanner.

EPC LIGHT IS ON wont start.

You need to have the system scanned to see what is triggering the EPC light. You can get your own VAG-COM to do the scan here:

Q5 2012, epc light on when drive at speed 70-80 km/h constantly for a distant. Change 3 oil switch censers, but doc light till on. Pls advise

Trouble with the running sensors or equipment on the engine. If a crank angle sensor, spark plug, throttle control, coil, fuel injector etc fails to perform correctly, this will trigger the EPC and a code will be stored in the ECU. Have it scanned and read the code/s.

Audi epc light

What ,year audi and model? EPC LIGHT PO299. let me see if i can find out with out year and model.
okay, if your car has turbo then this is correct, po299 low boost.
this may be caused by a bad diverter valve on the turbo, if you remove it and look ay diaphram for any cracks or splits in rubber, if it is then replace it ,check for an update valve at dealer.
there are other thing that can cause this code but start with that. a loose hose for the turbo can cause this code or bad turbo or clogged converter, or oil sulge problem.

Check engine epc code

The EPC yellow light is not a DTC code! EPC means Electronic Pedal Control.
First of all you need to access the Engine Control Module (ECM) using suitable diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC's memored. DTC = Diagnostic Trouble Code. Then you will bu full informed about the root cause of the problem, and you will be able to repair & replace bad pieces and reset the ECM. Then the EPC (Electronic Pedal Control) yellow light will turn OFF.

I have a 2002 AUTO Audi A4. About 2 minutes into

Dear produceqa_de,

I am not entirely familliar with this particular model, although in some similar models that I have worked on The epc (on deisel models) usualy indicates a problem with the particle filter.

This means that if your car has a particle filter and it has not reached a temperature that it can clean itself for a few months, it may become clogged and cause a restriction for the engine.

If you take your car to an audi dealer the mechanic will be able to do a quick test to confirm and he may then be able to overide the cleaning process and clean the filter. I would advise that this is done asap as dammage may be caused from very high exhaust temperatures.

Reguards Luke.

Ihave 3 error codes on my 02 new beetle they are: P1171, P0456, 01314. The EPC light and the ASR light come on after driving for approx 17miles then after shutting the car off then the next time I start it...

Sounds like you have and issue with your throttle sensor from the 1171, not sure of the others as they are not on the list so please verify. Here is a link to the codes for future reference, scroll to the bottom which list the DTC's..

Today my EPC light came on during driving, the engine "lowered" in rpm, I realeased the gas and the light came off. What is the problem? I noticed that I have about 0,4 liter to much oil in, could this be...

It is a problem with engine oil level. This can affect EPC light. NEVER you must fill up engine oil above the "max" mark of the oil dipstick !!! If oil level is above "max" there is risk of damage to Three Way Catalitic Converter !!! You must bring oil level at "max" mark of dipstick, but under no condition above !!!
