While driving the engine lamp came on and the test message indicated "emission workshop". The dealership found the mass air flow meter (p0101) to be faulty. It was replace but the problem and code recurred within 6 miles. Next the dealership found a crack in the turbo air cooler, it was replaced but the problem and code recurred within miles. The dealership has had the car for nearly 2 weeks when they found a slight air leak in a turbo hose. The "o" rings were replaced and it may have corrected the problem but I have not had the car since they are still working on the engine surge problem.
Oil sludge developed in the engine of my 2004 vw Passat wagon 1. 8t, causing excess engine wear and $2800 service charge to desludge the engine. The sludge was caused by a problem known to vw but not made known to vehicle owners. I would like vw to reimburse me for the cost of this service. At a minimum, I would like vw to notify all customers of this defect (including warranty coverage requirements) and provide periodic sludge checks, every one to two years.
After hitting 100,000 miles on 2004 Passat, the warning light came on for low oil pressure. I took it in to vw and they quoted me $2,800 to replace all oil lines and vacuum lines. I did some research and found out that this is a known problem with vw engines and even after doing the $2,800 worth of work, the engine will still fail within a year. I have gone to another repair shop to perform an oil flush and I was able to drive another 500 miles before the light came on again. I have gone for 2 more oil flushes. Now, they will do 2 oil flushes each time. The first time, there will be a lot of sludge that comes out and the 2nd time is clear. There is an obvious problem with sludge build up and will eventually ruin the engine. I know there was a recall on 1. 8t engines for this same issue. It is an issue with all vw engines, not just the 1. 8t.
Engine started fine, and let it ran for a minute or two on drive way. Then suddenly it died. Computer screen displayed "stop", oils pressure can, and low oil pressure warning lights came on.
Oil sludge problem with my 2004 vw Passat 1. 8l turbo has caused irreversible engine problems.
Vw Passat 2004 purchased new from dealer in Jan. Of 2005. We did our own oil changes following the manual recommended schedule and oil specifications (every 5,000 miles 5w-30 or 5w-40 regular or synthetic oil). We never received a letter from vw nor the dealership about the extended warranty for the known oil sludge problem nor any new requirements for oil changes. Most of the oil changes were done at home and recorded in the manual; two were done outside and have receipts. Oil pressure light went on at about 45,000 miles, car was towed to dealership. They recommended a new motor. Dealership contends that warranty will not cover it because they require synthetic oil only and for oil to be changed at the dealership. Vw warranty denied warranty service. Car is still at the dealership.
I have a vw Passat with less than 30,000 miles on it that has sludge in the motor and have been faithful with my oil changes but I am missing one receipt. Vw of America refuses to cover the work under warranty stating lack of maintenance on my behalf for the problem. They are taking no responsibility for the defective engines they are putting in these cars but blaming it on the consumers. I am sorry I ever bought this car and I am now left with no transportation for my kids to get to school and for me to get to work and I have no money to fix the car because I am a single mother living paycheck to paycheck. It is very frustrating that I have to be driving down the freeway with my 3 daughters in the car and have my engine freeze up and almost crash into several cars trying to get over to the side of the road. I then take it to the closest dealer to be treated like dirt and told I did not do enough to take care of my car. They then shuttle me off to some advocate for vw and he treats me even worse and tells me sorry the answer is no have a nice day. . I have never been treated so poorly in my life and I am appalled that I ever bought this car and will tell everyone I know about this issue and warn everyone I know to get rid of their vws.
