Crankcase (pcv) problems of the 2006 Volkswagen Passat

Bad ignition coils and misfires. Cam follower and camshaft wear problems. Diverter valve (dv) failure. High pressure fuel pump (hpfp). Carbon build up and cold start misfires. Intake manifold runner control (imrc) motor. Timing chain, chain adjuster and tensioner. Vw and Audi fuel pump control module. Pcv valve failure.

While driving in-city, I experienced sudden intermittent loss of power. My mil indicator started flashing a yellow engine light. After limping the car home (<1mile) my vehicle developed a hammering noise before I turned it off. I took the car to an auto repair shop and they determined the issue was engine sludge. After contacting vw regarding the issue they refused to take any actions. I have fully maintained the vehicle based on manufacturer scheduled service intervals, often more frequently than listed. I did learn there was an active recall for the positive crankcase ventilation system which can directly effect the development of engine sludge. Despite this connection, vw still refused to take any action on the damage to my vehicle.

I got 2006 vw Passat 2. 0t - 77,000miles. Last week, I got engin light came on during the drive and went to dealership and they checked computer system then fixed air filter housing. I paid $585. 00. I don't understand how it can be break, but I don't have choice. And next day on the driving it happen again and I went to dealership again. This time they told me pcv valve was not working so another fix cost $281. 00. Last spetember I did regular maintenance service and they told me everything good. But after every month it happened again and again, first problem was steering columns. . . . . . I paid $485. 00 second problem was battery. . . . . . . . I paid $130. 00 third problem was engin light came on I paid $585. 00 and this time another engin light came on $281. 00 within two day. Now I knew vw cars are pices of junks. It is really junks.

I have a 2006 vw Passat that had a crankcase breather valve foul up for no reason. The vehicle was maintained in accordance with the vw recommended maintenance schedule and this is documented, however, the vw service rep indicated this was a result of not properly maintaining the vehicle. Specifically he stated that this is what happens when the owner fails to change the engine oil. (note: vw recommends changing the oil every 10k miles and calls for the use of synthetic oil. Both recommendations were followed in this case). This incident occurred when the vehicle had approximately 48,000 miles on the vehicle. The vehicle was driven under "normal driving conditions"--primarily highway driving in a non snow, non desert environment. As a result of this defect, there was an increase in emissions. Also, the engine began to seize up while I was traveling on an interstate highway thus putting me and my family in danger.
