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.
Sludge in an engine is cause by poor maintenance. Air and contaminants build up over time to create a thick sludge throughout the engine.

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.

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.
The absence of a thermostat can lead to engine overheating or inconsistent operating temperatures, which prevents oil from reaching its optimal temperature. When the oil remains too cool, it fails to properly lubricate the engine and can become contaminated with moisture and combustion byproducts. This combination of low temperature and contamination fosters the formation of sludge in the crankcase, as the oil does not adequately break down impurities and maintain its fluidity. Consequently, sludge buildup can hinder engine performance and lead to potential damage.
Yes, diesel fuel can go bad after sitting for three years. Over time, it can undergo oxidation and microbial growth, leading to the formation of sludge and sediment. Additionally, the fuel's additives may degrade, reducing its effectiveness. It's advisable to test or treat old diesel before use to ensure optimal performance.
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
Kerosene can help break down sludge buildup in engines due to its solvent properties, but it may not completely solve the issue. Proper maintenance and regular oil changes are recommended to prevent sludge formation in the first place.
When a diesel runs out of fuel it allows air to enter the pressurized fuel lines. The air pressure does not allow the fuel to re enter the engine in a constant flow. Therefore the engine receives only a partial charge of fuel. The fuel pump and lines must be bled of any air. The other possibility is sludge contamination. When you run a diesel "dry" you can suck the sludge that accumulates in all diesel fuel tank into the fuel filter, fuel lines, and even into the injector assemblies. Over the counter DIY flushes, combined with changing the fuel filter, will sometimes fix the problem. Most times a professional system flush is required.
if sludge is keeping oil from draining away from valve guide a cylinder can suck in oil and cause plug to misfire
Try changing your oil and adding a quart of Marvel Mystery Oil, and a quart of Automatic Transmission Fluid as a replacement for two quarts of engine oil. run this combination for about 500 miles and change your engine oil. & filter. I have also seen kerosene or diesel fuel used to flush sludge from engines, but if you choose to use kerosene or diesel fuel DO NOT DRIVE YOUR VEHICLE!!!! Let the engine sit and idle for a couple of hours, checking temperature and oil pressure. Change your engine oil and filter.
