So I was reading another diesel forum today, and someone asked a question about their 97 jetta tdi. They mentioned a loss of power and fuel economy recently. The top response said to do an Italian tuneup. He said he does it to his 240d every 2-3 weeks. Just drive it at 4000-4500 RPM (close to redline) for 10-15 minutes and its like a whole new machine he claims. (IIRC, redline on those Mercedes diesels is 4800 or 5000).
So my question is this, is there any truth behind this idea, both in regards to all older diesels, and specifically our IDIs, or is it a fast way to blow the engine.
