Here is a complaint on the VW Passat 1.8L Turb Engines. I have seen this complaint many times. First read the complaint:
Complaint: For owners of 1998-2004 Passat’s with 1.8L Turbo engines, VW has extended their Power Train warranty to 8 years or 80,000 miles. They cite an the “Oil Sludge” problem. Apparently, VW is downplaying the real problem. Some defect in the engine can cause the oil pump to fail and quickly destroy the engine. It happened to my wife’s car on an extended trip a couple of weeks back. We saw a “Low Oil Pressure — Stop Motor” signal come on. By the time I pulled off the road, the engine was wrecked.
The worst part is that VW knows of the defect and will only provide warranty coverage if you have had the oil changed at least at exactly every 5,000 or six months, and you have receipts with VIN number and mileage (I suspect they would find something else to complain about if we had met this requirement). Since we have the oil changed at a little service station, we’re screwed.
Engine replacement is estimated at about $11,000. Some folks are luckier. They have to replace the oil pump for about $1,000, but eventually it fails again and in all likelihood eventually destroys the engine.
Thoughts: The problem seems to lie in when you time your oil change intervals and what type of oil you use. The issue stems from the PCV (positive crankcase ventilation) valve and hose becoming ineffective. The reason it becomes ineffective is because, primarily, the PVC is an emission system component that ventilates the crankcase when working properly. When the hose collapses or the valve fails, the waste oil fumes go back into the crankcase, where it becomes sludge.
The solution is to replace the PCV and hose every year or 25,000 miles (at your expense) so the valve and hose don’t fail. Is it ethically correct for you to have to pay for it yourself? No way. However, the frustration, cost of downtime and very real possibility of you having to pay for an engine replacement under warranty outweighs the cost of just replacing the hose and valve every year.
VW for all practical purposes denies there is a problem with this valve and subsequent sludge build up and engine failure. Take my advise and make it a regular yearly maintenance procedure to buy and install your own valve and hose. Don’t put yourself in a spot where you need a replacement engine for a VW Passat. By the way, $11000.oo is way to much for a Passat engine. Call GotEngines.com @ 1-866-320-1065. Speak with a representative who can help you decide which replacement engine is in your best interests.
