Durametric Fault Codes.
 

I finally got my Durametric in today. Plugged it in and the following fault codes came up.

0003- Upper Limit Value Exceeded

0103- Value Below Lower Limit Value

0303- Value Below Lower Limit Value

Truck is a 2008 Cayenne S. 64,000 Miles. Truck is at a loss of power,changed the plugs and coils and still having the same. Anyone know where I can find more information on these codes,or know what the codes are? Thanks again.

Did some searches and this is what I've found. Maybe someone else can give their input.

P0003 -Fuel Volume Regulator Control Circuit Low
P0103 -Air Flow Sensor - Above Upper Limit
P0303 -Misfire, Cylinder 3, Damaging to Catalytic Converter

Trying put in some new MAF's.

Hi,

I just noted these exact same 3 codes when checking due to my engine light coming on. I cleared the codes and am now trying to do research on them. Can you share any further insight? I don't have any loss of power as you did that I notice. I have a 2009 Cayenne S with 66K. Odd that the mileage is similar when these codes show up. Im currently waiting to see if the codes re-appear, but hoping I don't ignore something significant and end up regretting it..

Any insight is much appreciated.

Durametric is having problems with those year Cayenne's. The codes should come up ex-P1234. They say they are hoping to fix the problem soon. I have changed the plugs,coils,cleaned the MAF and still have the problem. I'm guessing i'll need new MAF'S. My 911 is at the dealer now getting worked on,when thats done I'm having them scan the car and tell me whats wrong. I will let you know how i make out…….

Thanks for the update.. so far for me the engine light has not come back.. hoping it was a fluke... look forward to hearing if the MAFs fix your problem.

R u still experiencing loss of power? how can you tell...what are the symptoms? just general sluggishness or something?

My 09 GTS has an intermittent check engine light
 

Just bought it with 71,000 mi, but the engine runs like a top. Very smooth and steady at 500rpm idle, and smooth as a kitten to redline with never a miss. My check engine light comes and goes but is on most of the time. I was thinking about ordering the Durametric to see what it says. Hopefully Durametric figures out the issues with these Cayenne models soon.

I have a 2008 V6. My CEL went on and got P1090 & P1109 faults in the Durametric. Both point to Bad MAF sensor. I replaced it and the CEL has not returned.

My check engine lights came and went, with mileage in the low 70s, and that 4.8L V8 kept purring like a cat. Durametric said it was AMFS. Two different techs told me this is common and can be fixed by cleaning the AMFS wires (don't touch them) with a spray CRC makes. I just kept resetting mine.
