2010 Volkswagen Passat engine problems

Filed Oct 23, 2024 · Engine, Steering · CA

I purchased a used vehicle but have found out the oxygen sensor is feeding false error codes to the main OBC causing leaks into driver compartment causing engine to stall while auto in motion and most importantly causing steering wheel to lock, have spoken with VWoA but they have no direct influence with VW or dealerships even if a warranty issue because all parties are independent contractors and all they are able to do is try and help. My name has not been transferred to registration because of smog requirements so you may call me [XXX] my telephone number is [XXX] my case# with VWoA is [XXX], I myself have learned to deal with defects but should this matter be more widespread which I cannot find out because the last case regarding the sensors was sealed in an agreement made by the California ARB, EPA and VW and Audi through a settlement signed in December 2021. Once again my hands are tied from taking much more action but I believe your department whether is able to enforce this matter or not should at least investigate and issue warnings to advise people of what can happen so if they can even at own cost seek appropriate repairs before more damages accrued. Also if this sensor is effecting more models and manufacturers an appropriate temporary fix should be seeker since no long term solutions are available at this time INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Drove the car to and from work that day with no problems. Also, went back to work a 2nd side job that evening with no issues. Got home, shut the car off and when my wife and I went out to go to work the next morning at 5 a.m., the car wouldn't start at all. Wouldn't even click. Did a lot of research because I had the starter replaced about 2 weeks before and knew it couldn't be the starter and also had bought a new battery when I had the starter replaced as well, so knew it wouldn't be the battery. After a lot, I mean a lot of research online, finally came to the decision it was the timing chain tensioner was faulty. When I went to replace the tensioner for the timing chain, I took my camera and put it in the cylinder heads and found out that there was 2 broken valves in the number 3 piston. One was broken and sideways in the piston and the other just broken. I'm not sure whether a rod has gone through the bottom of the head or not, couldn't get my camera to go that far down. So now I have no vehicle what-so-ever to drive back and forth to work. My wife had to resign from her job because she had no way to get there everyday and I have to pay someone gas money weekly to pick me up and bring me home from work so needless to say, we are currently struggling, can't pay our bills because my wife cannot get a job and now I have to figure out how to repair this damage that should have been made a recall for these volkswagens because by the looks of things, there are over 100 people that have had this same problem. An engine is going to be between $4,000 and $6,000 to repair and I have no way to fix this at that price. So now I am probably going to have to just junk the car.

faulty timing chain tensioner caused catastrophic engine failure. resulting in ~$4000.00 repair cost. i have read about alot of other Volkswagens having this same issue. VW has redesigned this part several times, i did not recive a TSB stating there was an issue with an internal component of my engine even though VW knows this issue will result in engine failure.

While driving the vehicle looses power, I can stop shut it down and it runs fine for a period. The problem is unpredictable, I am afraid to drive the vehicle on on interstate highways, because a serious accident would occur.

The car wouldn't start and found out the timing chain jumped

My volkswagen passat has fallen to an issue many others have fallen. It appears the timing-chain tensioner failed causing the timing-chain to jump. When this happens the valves can bend and also ruin the cylinders. The error code is p0016. Vw west broad is recommending a repair of $5,100 dollars. After discussing with vw of america they will not cover as it is outside of their extended warranty 100,000 miles or december of 2019. My car is approximately 111k miles and 6 months past the date. I was not made aware of this issue so I could not be proactive in fixing the tensioner. They even redesigned the timing-chain tensioner because the old one is faulty. I am lucky I was able to make it home from my day trip this past weekend and that the issue did not take place while driving. I was in a parking lot on top of a mountain. It took 4 or so seconds to start which was abnormal, but proceeded to run. The check engine light came on, but I was able to proceed home. Several days later I tried starting the car to bring to the shop, but it no longer starts and I had to get it towed. At this point, I am prepared to send it to the junk yard because the cost of the repair is beyond the value of the vehicle.
