problem diagnosed at three shops- all coming up with same code indicating catalytic 2. Know it will be labor intensive- just what is procedure for it's replacement?

If i run my car to freeway it overheat and oil pressure sign lit .

I did do electronic check they cleared the error it drives but when I drive on high spread when I brake it goes back in safe mode again.when its about to come to a coplete hault it gives a grinding sound on front wheels

The problem always happens after being on the freeway for over an hour and continues at slow speeds and in 1st through 6th gear after I get off of the freeway. After the car has been parked for a few hours the shuttering (shaking) problem goes away.
The engine seems to be running fine.
Could this problem be drivetrain related?
The engine has just been professional tuned and fuel filter has been replaced. Transmission was rebuilt 5,000 miles ago.

My w8 has stock hid lights, well I replaced the ballast and it worked for two sec then the fuse blew and so did the new ballast. Now I'm stuck iv spend 500$ on not the problem and now I need to know what to do?! Bc the passenger side lights works but nothing on the driver side dose.

Chief mechanic said 6 days. I brought it in on the 17th.
90% of transmission is being replaced.

my check engine light goes on and off every few hours, but other than a lil kick when tapping the gas it seems fine. HELP IS APPRECIATED!!! my first car lol 125k miles btw

My mechanic told me that it'll cost eleven hundrend US dollars to fix the right rear window for my Passat W8. He said that the motor needs to be replaced. Does it really cost that much?

I'd appreciate your help.

The tank is not full

How i can change automatic transmission oil?

When switching out the battery on a W8 do you need to reprogram the computer settings ? I have been told NO and I have been told YES...which one is it?

Everything electrical stopped working on my daughters W8. Windows, powere locks, etc. What causes this and is it going to be an expensive fix?

Hi, there! My vw passat W8 is running rough, Had it check, after replacing 6 coils and two injectors,which was sum of the codes which flagged up.
Still not right, on start up fine , then 15-20 sec later idles rough, runs fine above 1700rpm.
Cam shaft to crank positioning error
Can this be reset or it is engine out and do cam belt?
thank you

I am located in Melbourne, Australia, and my W8 Passat has done 142,000km. It has just had the original battery replaced, but upon replacement, the electrical system no longer functioned properly. The rear vision mirrors, central locking, power windows, etc. no longer worked. The VW service people told me that the control unit under the passenger side floor had possibly been water affected. Can I access this myself, under the carpet, or is access possible only from under the car?

I have opened the control unit in the boot, which had water in it, cleaned it up with a toothbrush and dried it out. The central locking, air conditioning and rear vision mirrors are now working. The fuel gauge, however, is not, and the trip gauge is registering odd numbers (actually going backwards). Can you please tell me which functions are controlled by the unit under the floor and which are controlled by the unit in the boot?

The car is due to be returned to the VW service centre soon, so that they can continue to try and remedy the problems, but in view of my success with drying out the control unit in the boot, I would like to have a go at resolving the other problems myself.

Does the dealer have to change it or can I

I am looking at buying an 03 Passat W8 w/95,000 miles & 1 owner car. It is very clean and have had it inspected all checks out. I plan on getting an extended warranty if I purchase. I like the car but am afraid it wind up being a money pit since they do not make this car anymore. The closest dealership to where I live is 1 1/2hrs away so I cannot run it to the dealer all the time for issues. I want a reliable nice used VW. Any input would be greatly appreciated.

The air conditioner fan is blowing but the air flow is low...

My dealer told me that my Passat w8 with 56,000 miles needs a new thermostat and to replace the thermostat the engine has to be removed and it will cost $1200. Repair Pal says it should cost 3 to 4 hundred. Who is right?

I need to replace my thermostat - it is not warming up properly - how much should this cost me with labor and parts?

The mechanic told me that to replace the spark plugs that he is going to have to take out the engine. Is that true? How often do they need to be replaced and how much should they run?
