Volkswagen Passat W8 Problems
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.
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.
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.

So far 1,000 miles I love the car I do have the check engine light on I know the owener said when it is cold it is slow to get going but I have not seen it just the check engine light I will have to see what the code is but nice and smooth...
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.
