Hi there,
I don't know about VW Passat's having this as a typical problem, Oil jelling is a problem where the incorrect oil is used for long periods of infrequent use in very cold conditions. A problem normally associated with diesels where a high wax content of fuel is used. I often came across this problem with industrial machines left idling for long periods and suffering from lack of oil changes, often the oil being just topped up instead. Now for a passenger car to suffer this type of damage in my location (warm to hot conditions) is very uncommon. I would be asking for a detailed report on damage before considering what to do about it. There may be other reasons why the oil pressure was indicating low, I would want to know that they have diagnosed the problem correctly.
