Polo 2011 vivo 1400 - diagnose codes P0302 and P0300
« on: April 04, 2016, 06:30:16 PM »
This car problem was that the engine idles roughly and it performs very bad, goes in limb mode. I have pulled codes from the ECU and got the following:
Cylinder 2
P0302 - 000 - Misfire Detected - Intermittent
Freeze Frame:
Fault Status: 00100000
Fault Priority: 2
Fault Frequency: 2
Reset counter: 6
Time Indication: 0
Freeze Frame:
Bin. Bits: 00000100
Load: 100.0 %
Lambda: 0.0 %
Speed: 60.0 km/h
Temperature: 46.0°C
Absolute Pres.: 796.3 mbar
RPM: 2250 /min
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 000 - - Intermittent
Freeze Frame:
Fault Status: 00100000
Fault Priority: 1
Fault Frequency: 1
Reset counter: 7
Time Indication: 0

Now this could be as follows:
1.Plug dead at no 2 piston
2.Ignition coil faulty Piston 2
3.Injector no 2 - faulty

I have remove the plug from no 2 and it is completely black, not wet black but pitch black, this indicates that this piston is over fueling. I have done a coil test and it test fine.  Now to enable me to really pin point the problem  I have change injector 2 with no 4 and ask the customer to bring the car back after a day or so.  After customer brought back the car with same problems I have pulled codes from the ECU again and just look at the results
16688 - Cylinder 4
            P0304 - 000 - Misfire Detected - Intermittent
             Freeze Frame:
                    Fault Status: 00100000
                    Fault Priority: 2
                    Fault Frequency: 28
                    Reset counter: 0
                    Time Indication: 0

             Freeze Frame:
                    Bin. Bits: 00000100
                    Load: 100.0 %
                    Lambda: 0.0 %
                    Speed: 64.0 km/h
                    Temperature: 86.0°C
                    Absolute Pres.: 795.6 mbar
                    RPM: 3556 /min
Now the problem is at no 4 piston, this definitely indicates the injector is faulty
Hopes this helps
