2004 Volkswagen Jetta: check engine light

Filed Nov 16, 2017 · Fuel system · 145,000 miles · OH

The car randomly stalls while driving whether at highway speeds or in town. This causes a loss of power steering and power brakes which is inherently dangerous in certain situations. It has been doing this regularly with the previous owner for the last 3 or 4 years and has done it 4 times while under my ownership since september 2017 it usually happens while there is less than 1/4 tank of fuel. When it happens there is no check engine light nor does the ecu store any codes from the problem. Previous owner made several repairs including a fuel pump and filter, engine speed sensor and alternator wiring harness in an attempt to fix the issues with no success. This issues also comes up regularly on several vw forums and no one seems to have an answer. This is a known and regular issue with no consistent repair and needs to be remedied.

Over the past few days it has been raining heavily & although it has happened to me once before this time is what worse. My car is leaking from somewhere & its coming on the inside. My carpets are constantly wet, my airbags alongside windshield leak, and the handle where you open the hood of the car is literally a stream of water entering the car during heavy rainfall. The airbag light has come on and the check engine. I was more concerned with the check engine light so I went and got it checked. The code came up as u0155 - which refers to (lost communication with instrument panel cluster (ipc) control module) meaning my entire dashboard needs to be replaced because of this leaking ! I have taken my car on multiple occasions to vw dealership for servicing (never for this problem) and they never once told me anything about cleaning the sunroof drains every two years as maintenance, it is visible to the naked eye that my sunroof is messed up because when I purchased it the lining on the car around the sunroof is drooping and I cannot open the sunroof because of this. I never thought of it as a big deal because I don't use a sunroof but how was I supposed to know there was a leak without anyone telling me that was even possible. I looked up this problem online, that's how I know what's wrong with my car. I refuse to get it "diagnosed" and spend over 200$ on just a diagnosis when I already know what the problem is and they'll end up charging way more to actually fix the problem. This is my first car and I don't know much of anything about cars except keeping up with oil and filter changes, fuel injectors, and changing my tires when the tread is getting low. I have done all of that at each checkpoint since I purchased at 63,000 miles. There is so much condensation inside I can barely see out my windows, I have sit for at least a half hour car on to be able to see & drive.

I purchased my car back in october 2013. When I purchased my car, the mechanic said that he replaced the ABS system. The lights were not on when I bought it. A few months later, out of the blue in about april 2014, I was turning my car on and the engine light, the ABS light and the brake light all came on momentarily after turning my engine on as I was still in park. My car had close to 100,000 miles on it. The problem went away and shortly came back a week later. Ever since, it has been on. Every once in a while, all of the lights would go off. Luckily the lights all went off for a few days around my inspection time for the 2014 year and my car passed. Not even three days later they all came back on. This time october 2015 inspection is coming up and my lights are all on. Since the engine light is on, I cannot pass inspection. The code reader says it is a miscommunication error, or a u0121 error. I have done a lot of investigation and cleaning up the module and the contacts, cleared the codes, and my problem is still there.

On march 25, 2007, I woke up to a strong fuel leakage odor, seeking for air, almost finding it impossible to breathe properly, forcing me to evacuate my house at late hours of the night the gas smell was coming from my car in the garage. I called dealer, explained matter. Dealer told me my car was no longer under warranty for this kind of service/or repair. The car had 49,419 miles and was 4 years old but volkswagen warranty is covered for 50,000 miles or 5 years whichever occurs first. I called volkswagen but they only confirmed the dealer's statement. Took car to local shop, they replaced fuel tank and fuel pump on march 26, 2007, cost $754.11. Three months after the strong gas smell came back only difference the engine light came on and smell was not as strong. I took car to a different shop on may 22, 2008 they repaired gas tank and fuel pump seal costing me $316.20. This april received a letter from volkswagen for faulty catalytic converter, researched connection to potential gas leak and found in disbelief the gas leak recall on 2005, which I was not notified in 2005 or 2007.

Gas idles like it is stuck when over 40 MPH or like I have a stick shift and I am in 3rd gear driving and not switching gears. Two months ago the car went dead while I was driving and the dealership replaced the fuel pump. After about two weeks the check engine light came on and off again and again, then the dealership replaced the coil, but it still has the same problem.

About a month and a half ago I started to notice that my 2004 jetta gl was starting to run a little rough. I brought it to the deal and had a test done on it to find out the my ignition coil was bad. After about 2 weeks the check engine like came on it the car and I called the dealer to have it looked at. Again my ignition coil had gone bad. Then yet another time a week and a half later the same issue. The ignition coil had gone bad. Three days later after that incident I was driving and the check engine light came on. This was the forth time that I had the same problem. This time the dealer changed the wiring harness and said that that was the problem should be cured. All of the times that I picked up the car from the dealer I noticed that the idle it the car was still a little rough and needle for the tacometer was moving slightly. I am still weary to say that the car is fixed and fear something more exstensice is wrong with the car. The car is still under warranty and the parts were replaced but consumer satisfaction is low.
