Durametric error P2C02 & P2F01 & P3301

[Guetstar]

Hello at all!!

I am Alex from France, i have a Cayenne Turbo 2003 with 68,750miles (110.000kms)..

I have a problem with cylinder 3 & 7, when i have do check control with durametric, the result is:

Bosch Digital Motor Electronics 7.1.1

Codes d'erreur actuels

P0300:

Some missfire detected - Value below lower limit value, test conditions are not-completed, fault is currently active and causing a DTC light

P0303:

Missfire detected cyl. 3 - Value below lower limit value, test conditions are not-completed, fault is currently active and causing a DTC light

P0307:

Missfire detected cyl. 7 - Value below lower limit value, test conditions are not-completed, fault is currently active and causing a DTC light

When i run "short test" on all vehicle with durametric 6, i found same problems but with different ERROR CODE

Bosch Digital Motor Electronics 7.1.1

Codes d'erreur actuels

P2C01:

Some missfire detected - Value below lower limit value, test conditions are not-completed, fault is currently active and causing a DTC light

P2F01:

Missfire detected cyl. 3 - Value below lower limit value, test conditions are not-completed, fault is currently active and causing a DTC light

P3301:

Missfire detected cyl. 7 - Value below lower limit value, test conditions are not-completed, fault is currently active and causing a DTC light

I have never see in the past this error codes, i've found error code p3301 is:

Bank 1, cam shaft position sensor, discharge opening (G300), interruption / short-circuit tp B+

but one thing i no understand, p3301 is error for cyl.7, but p3301 is bank 1, and the cyl.7 is in bank 2, tell me if i'm wrong..

I have already change ignition coil & spar plug

I will need help

Thanks U.S.A.

Check all the fuses. A failing ignition coil can sometimes cause the fuse to fail. I wouldn't worry about the camshaft position code until the misfire issue is corrected. Then clear all codes and retest.

[Guetstar]

Thank you for your fast reply, i will check it tomorow! :cheers:

[Guetstar]

No idea about error code P2C01 & P2F01???

[royxaxa]

did you check the timing?

i read somewhere if timing is off, it might cause misfiring.

[Guetstar]

hi, thanl you for your reply, what do you mean by "timing"? thnk you

[Guetstar]

I deposit the vehicle to the workshop .. verdict tomorrow ..

[Guetstar]

ok.. i've change all the spark plug and all is ok now!!! strange obd code error!!

[Guetstar]

hi

i'va again misfire dtected on cyl n°3 only now, i've change the 8 spark and coil..

when i test with durametric on actual value i've misfire only on cyl3 and low rpm, when i put rpm at 3500/4000 i no have misfire!!!

someone have an idea?

[Guetstar]

WAAAAAAAAAAKE UUUUUUUUUUUP!!!!!

[Guetstar]

hello at all! someone have a rapair workshop manual of cayenne turbo 2003???

[Loren]

Please rerun the fault codes - some of the ones you gave before are not valid faults.

What fault codes do you have now? (please reset all faults and then re-test)

[Guetstar]

hi thank you very much for your reply

i have fault code p0300, p0303 and i have sometimes p012f and told me misfire detected cylinder 3 code error p012f..

[Loren]

P0303 is a misfire on cylinder 3. P0300 is multiple misfires detected.

There is no fault P012F - either your code reader is bad or you are misreading it.

Most Cayenne misfires are caused by bad ignition coils - especially on the older cars. Porsche has updated these coils several times.

[Guetstar]

Thank you Loren for your reply

i have already change ignition coils, spark plug, check injector, check compression engine, check wiring,.

[Loren]

If all those have been tested properly then you need to look at lifter or valve problems.

[Guetstar]

but engine compression is good at all cylinder..?

i can have good compression and valve or lifter problems?

[Loren]

Sure - because they are not moving when you do a compression test.

I would get a second shop to investigate this problem as some of the results just don't make sense.

[Guetstar]

:cursing: :eek:

i've make a video

car smoke white but more than 1 week engine no work and when i've take video engine work 5min..

[wvicary]

You need to have number 3 cylinder inspected with a scope for damage to the cylinder wall. I would also inspect the electrical connector for damage on that coil and the fuse for that circuit. Did you install an OEM plug and coil?

[Guetstar]

i've install ngk plug and beru coil..

wednesday i've change injector 3 to the 1, and now appear misfire cylinder 1, 3 and 7, maybe is fuel pump or battery, battery is little tired, and fuel pump no change!

[Loren]

Sorry, you are guessing...

[mudman2]

What part number are the coils that you have in now, the last 3 digits will be 003, 005, 007 or something like that

[Guetstar]

yes i've install oem coil and plug.. yesterday i've found oil on admission circuit on bank 2..

[Guetstar]

Hi at all! i no have compression at cylinder n°3, i'm checking exhaust valve, but i would like to know if someone have a workshop manual, for valve timing? I really need your help for that thank you
