Good quality oil, no short runs, always get the engine up to temperature, regular oil and filter changes, regular engine flushes.
Flushing sludge from your engine is not a very smart thing to do. Almost every automotive technician will agree with that. Flushing out an engine causes all the sludge to drain down into the oil pan. Which in turn tends to plug up the oil pick up and causes engine damage.
Have it checked out. Probably engine coolant working its way into the oil. Possibly head gasket and/or cracked head at fault.
I went to Lincoln Tech Auto school and the Professor in my Automatic Transmissions class told me the best thing to do, to clean out your engine is to put Automatic Transmission fluid in it and run it over the weekend and then change it out with regular motor oil.
You oil will get dirtier and dirtier, the filter will clog and the engine will start the wear. Eventually the engine will develop sludge and in the end the engine will not last very long. I would suspect a brand new engine that you kept driving and never changed the oil might last 50,000 miles at the outside before having major internal problems.
Stops dirt from entering the engine which will damage internal parts.
Sludge in an engine is cause by poor maintenance. Air and contaminants build up over time to create a thick sludge throughout the engine.
If you have the 2.3 engine, one possibility is sludge in the Throttle Body.

one sing can says a lot: check in your oil cap, if you find some oil sludge, its a big revelation that you have oil sludge problem in the engine
It would take a long time before the oil would sludge up to the point of not allowing the engine to turn over.
Engine sludge formation includes, lack of proper maintenance, inappropriate oil temperature, use of an inferior engine oil, and engine oil contamination. You can try flushing it out with an oil flush additive but often times this does more harm than good.
Yes, stop leak turns into a thick substance to plug any leaks, when it ends up in the overflow bottle it turns into sludge there.
While a V6 Passat can sludge (as can any engine), it is not nearly as common as sludge issues on the turbocharged 1.8 liter engines. The reason for the difference is that the heat from the turbo, combined with an inadequate oil capacity (under 4 liters) breaks down the oil and forms sludge. The V6 engine, being a non turbo and having a larger oil capacity is less prone to sludge. However, as is the case with any engine, prolonged oil change intervals and cheap oil/filters will increase the risk of sludgeing over time.

if sludge is keeping oil from draining away from valve guide a cylinder can suck in oil and cause plug to misfire
With pliers if u have sludge in your engine
