I explained this could put me & my family at risk of injury, even possible death due to a highway accident, not to mention the cost I could incur for another tow truck & hotel expenses. They told me they would not help me due to internal policies, and that I should drive the car as is, until the issue came up again. I did so, and I got the same response from my local dealership. They told me they could not help me, and advised to take the car and drive it to the dealership where I lived. Their internal policy required the fault to be present for the company to comply to replace faulty parts, even when they had the records. The dealership technician told me that they recorded several piston misfires, but after resetting the computer, the faults never came back. I waited 5 hours to find out what was happening, as I live in another city. I lost total engine power, and I had to call the towing truck to take me to the closest dealership, as the car is still under warranty. I was barely able to pull over to the shoulder, and drive off the upcoming exit ramp. Then the epc & check engine lights turned on, on the dashboard. While traveling on the freeway in san diego, my car started shaking and losing power. Vw should have issued a bulletin for servicing this known issue and we would not have been forced to buy a new vehicle, moreover, they should have issued a recall as this could be fatal if it went out while driving. It had 150k miles, but we should have been able to drive this car for many more miles. We took great care of this car including servicing as recommended. The dealership must dismantle the engine to determine root cause and price for proper repairs, which they are estimating as $2,000 to $5,000 - which is more than the car is worth. Thankful that this did not happen while driving as it would have been very dangerous. They determined the timing chain slipped. They performed diagnostics and then went to pull the vehicle out of shop and it would not start. I took it in to the vw dealership to look at it for the second time. Tech Tips: A failed crankcase pressure regulating valve can allow boost pressure to enter the crankcase and force the rear main seal to dislodge.When turning corners, check engine light would flash on and engine would sometimes misfire. Remove the dipstick and smoke test the crankcase, if smoke comes out of the transmission bell housing the seal is leaking. There have been many cases of leaking rear main seals that create a false air leak. If the idle cleans up or block 032 idle fuel trim starts to drop, either a false air leak into the system is present or the regulating valve has failed.Ħ. If no external leaks are found, try blocking off the vacuum supply to the crankcase ventilation system. Inspect the intake system for leaks, smoke testing the system with pressure is the preferred method.ĥ.
If the values are +5% or more, a lean condition exists. The maximum value before fault detection is +or- 10%. The first value is idle fuel trim, the second value is part throttle fuel trim. Then test drive the car and evaluate block 032 in the ECM with a scan tool. Once the correct fuel pressure is being displayed, let the car idle for ten minutes. If the ECM reads nothing or a fixed value, check for a broken signal wire.Ĥ. There is no specification for voltage values, but lower voltage indicates low pressure and higher voltage indicates high pressure.
The center wire is signal voltage output to the ECM.ģ. Pin 3 Black/Gray is 5 volts and pin 1 Brown is ground. If the sensor is reading erroneously, verify that the sensor has proper reference voltage and ground. The fuel pressure is tested by utilizing a special tool and comparing that value to data block 230 in engine electronics with a compatible scan tool.Ĭlear all fault codes before testing the fuel pressure to ensure the vehicle is not in power limitation mode.Ģ.
2009 VW CC CHECK ENGINE LIGHT CODE
This fuel pressure fault code may be caused by a lean condition. After doing some research also found out that P119A typically falsely sets when a lean condition is present.Ĭustomer Concern: The engine runs rough and has fault codes P119A and a P0171. Also, the crankcase pressure regulating valve on top of the valve cover will need to be replaced at the same time. has failed and will need to be replaced. Found large amounts of smoke exiting between the transmission and the engine indicating rear main seal I first verified system was actually running lean by checking fuel trim values on the scan tool and did find that vehicle is adding a substantial amount of fuel to compensate for the lean condition.Ĭontinue diagnostic buy smoking intake system and crankcase for vacuum leaks. Diagnosed check engine light found storage code P0171 system lean bank 1 also found stored code p1193 a for fuel pressure sensor malfunction.
