They do sell them and I know a few people here have them, maybe they will chime in. All TDI turn the oil black. The high detergent additives take care of it. Although it may not seem right, many people have done oil analysis and it shows that black oil protects as well clear oil as long as the oil is doing its job. If the impurities hurt the engine it would show up in higher wear metals in the engine oil analysis, which it doesn't. There are also long life additives in the oil which are good for 10,000 miles, the factory suggested oil change. This is why you have to use synthetic compression engine rated engine oil. PD engines (pumpe duse) like thicker oil to help avoid camshaft wear and the new common rail engines (2009+) require 507 engine oil because it's very low ash which is for the exhaust filter.
