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.

2003 Volkswagen Passat W8 Problems
A problem with the torque converter can cause the Check Engine Light to illuminate.
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 drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.

Great car. Never had a problem except for normal maintenance. Looking for another with low miles. Best 8 cylinder german car made and better if you by one used with maintenance records. Price another German 8 cylinder and you will understand.
I will never buy a limited addition again. I've replaced the expensive hallogen head lights once a year several years in a row now. My computer board fragmented and I replaced that. My ABS brake harness broke, that was another $600. My drainage lines for the sun roof melted together causing the water to back up into the car, ruining my headliner and rusted the entire floor in my car. I kept calling the VW customer service with these complaints and all they said was "there is no recall". However other VW Passats were having the same issues, just not enough W8 complaints and why would there be, there isnt enough of that model to get feedback from so a recall will never happen.
Great car, gas guzzler.
Scary expensive to maintain, parts availability is spotty at best, super-tight clearances make working on them a nightmare. Simple maintenance is pretty straight-forward to perform however.
