I now have a scan of Shug.
Not content with fixing 1 FSi I now have 2! So lots of things to work on, some of them the same!
As per Project Stob I'm open to any offers of help, I don't profess to be an expert, but I hope to be much more knowledgeable with everyones help and to give back to everyone some interesting films of the fixes I try and how these cars can be kept running.
Thoughts suggestions? Constructive or otherwise
- 17439 - Intake Manifold Tuning Valve (N316) - P1031 - 35-00 - Setpoint Not Reached - OH NO NOT AGAIN!
This is the typical FSi flaps issue - it could be the potentiometer or the vacuum actuator
2. 16684 - Random/Multiple Cylinder Misfire Detected - P0300 - 35-10 - - Intermittent
3. 16685 - Cylinder 1 - P0301 - 35-10 - Misfire Detected - Intermittent
So this means there are multiple misfires, and specifically P0301 is saying what cylinder is involved - cylinder 1 plus P0300 is saying others randomly. VCDS can be used here to check the misfire count -
- Check that the battery is holding a good voltage - cars can start but still not operate the sparking system effectively with a low voltage - check for 12.8v whilst stopped. Check for 13.7 - 14.7 whilst running.
- Check the alternator is operating effectively - same as above
- Check the spark plugs and coils are in good condition and installed correctly
- Check for a vacuum leak in the system - check air intake system
- Check the high pressure fuel pump is working effectively and that the fuel filter is in good order
- Ensure that the correct fuel is in the system, super unleaded.
- Check common ground failures - behind light and on B pillar
4. 17441 - Sensor for NOx (G295) - P1033 - 35-00 - Signal too Low
5. 16395 - Bank 1: Camshaft A (Intake) - P0011 - 35-00 - Retard Setpoint not Reached (Over-Advanced)
6. 01271 - Positioning Motor for Temperature Flap (V68) - 41-00 - Blocked or No Voltage
7. 00856 - Radio Antenna - 36-00 - Open Circuit
