Purchased 2001 Passat in may, 2005. Had same 'non-covered' oil pump problem as many on the list have. Last month, noticed a pool of oil on the garage floor after backing it out. Looked under the hood, noticed that the antifreeze overflow looked like a chocolate milkshake. Oil cooler and oil cooler seals had to be replaced. 76000 miles.

2001 Volkswagen Passat coolant warning light illuminated and engine shut off. Once the vehicle was restarted it ran at reduced power. Upon inspection mechanic determined there was a faulty sensor in the cooling jacket. Moisture invaded the sensor, migrated up the wiring harness and destroyed the computer which managed all engine functions. The consumer was billed $3200. The technician at the dealer explain that this was not an uncommon failure. The consumer contacted the manufacturer but they refused to provide any assistance.

A/C slowly stopped blowing cold air, fumes or smoke began coming out of the vents. Coolant leaked all over the passenger floorboard which is now ruined. Dealer said the heater core needed replaced which was not covered under the extended warranty. Total repair cost was $1700, all this and the car only has 35,000 miles on it. I have heard that this is a common problem according to the dealer. Eyes have been burning lately from the smoke that was being blown through the vents. Dealer replaced heater core and there is still a bit of smoke being blown out. Very displeased.

My 2001 Volkswagen (VW) Passat experienced a problem that is well documented in the Volkswagen Passat user community as frequently occurring and confirmed by VW service technicians as a problem seen often. My service technician reported seeing this problem about 4 times a month. The car contains a pollen filter. The seal around the pollen filter failed. When the seal fails, water comes into the car around the passenger side footwell, flooding both the from and rear of the car, and, in our case requiring about $600 worth of repair. Reported consequences of water coming into the car, include (1) subsequent failure of the instrument lighting N the center console, making the audio, ventilation, anti-slip override and emergency flashers more difficult to access at night; (2) failure of either the airbag triggering mechanism or the airbag warning light, owner cannot distinguish; (3) and failure of the central locking system (doors and trunk -- locked doors cannot be unlocked from outside.) this problem occurs when the car gets wet -- for example when driving in the rain -- and results in failure of systems related to interior lights, electrical components, airbags, and locks -- all critical for safety in either normal or emergency situations. Volkswagen has denied my request for financial relief from the repair costs I incurred fixing the failure of the pollen filter seal in my 2001 Passat.
