2004 Volkswagen Passat Problems
The anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.
The digital display portion of the instrument cluster may fail. Our technicians tell us the entire instrument cluster will need to be replaced to correct this concern.
Clogged sunroof drains can allow water to enter the interior and accumulate under the carpet where various control modules are mounted. Over time, the accumulated moisture can damage the control modules.
Our technicians recommend having the constant velocity (CV) boots and CV joints inspected at each service. Servicing torn CV boots early can prevent the need to replace the CV half shaft or CV joint.

2004 Volkswagen Passat Reviews
I brought a used 2004 passat GLS sedan in 2011..It has been a pain, costly repairs..Never ending oil leaks...I would not recommend this vehicle....
I liked this car until I got the famous "oil pressure" light. The engine blew before I could slow down to pull over! VW is aware of the problem but because I bought the car used I cannot provide all the service records. I changed the oil every 3000 miles but that is not enough for them to cover the warrenty. I will never buy a VW product again!
This car has served me well. Other people have told me they've had electrical problems with the Passat, but I've not had any.
