So I just bought a 2006 Audi A3 2.0T from private party. It has 131k miles on it. Less than 24 hours later, I was driving to the bank and all of a sudden my EPC light came on and I wasn't able to accelerate normally. It was a lot slower. About 2 minutes later, my check engine light came on.

I had the codes checked and they came up with several:
P000A - Camshaft Position Slow Response
P2293 - Fuel Pressure Regulator
P0008 - Fuel Rail
P2293 - Fuel Rail
P2294 - Fuel Rail

I need some help on what to do next...

 

Where is the fuel filter on the 06 A3?
Also, how do you change out the camshaft position sensor?

 

Found the fuel filter... Passenger side, by the tire.

Now.... how to change out the camshaft position sensor...

 

Sensor is on the end of the valve cover just where you would picture the end of the cam shaft is.

I would not replace it until you have done the fuel filter and reset the codes. Most of the time when you get multiple codes, there is only one fault, the rest are just telling you what is happening. So when you think about it, a clogged fuel filter can provide low fuel pressure, that would result in fuel rail errors and therefore slow engine (cam) response.

I try not to just start swapping parts out (especially the expensive ones). Replacing filter and plastic bits by all means, but a cam sensor should not just fail.

Replace the filter, clear codes, go for a drive and run the scan again.

 

I replaced the fuel filter, cleared the codes. Turn my car on, EPC light is still on. Check engine light is off. Drive my car around for a bit. It feels the same way it did before.. I'll get to 3000 RPM and it feels a little rough, in any gear.

I get home, turn car off, back on, engine light and EPC are on. Rescan for codes:
1 code = 2294 for Fuel Rail. Thats the only one that's coming on right now.

 

Ok so it's still a fuel problem, not a cam problem except there is a technical service bulletin TSB 2015153 (01-09-03 > 15-10-01 > 15-10-02), the Intake Camshaft might have a worn out Fuel Pump Cam.

Possible Causes:

Fuel Pressure too Low
Intake Camshaft Failure

Possible Solutions

Check Measuring Values for Fuel Pressure
Check for bent/squeezed Fuel Lines
Check Fuel Pressure System for Leaks
Check Fuel Filter & Filter in Fuel Pump
Check Fuel Quantity supplied by the Fuel Pump


Check the Fuel Pressure first. (do you have a VCDS available?).

did you solve this problem if so what fixed it?
