Been reading around the net. Trend in what I see seems to say, cleaning the
EGR to make sure it shuts properly, then blocking the vaccum hose to it, and
the ARV, makes
for a much longer lasting, better performing, more MPG, healthier turbo
Seems as euro cars never even had this stuff. If any MB diesel mechs hang
here, could you give your opinion, theoretically? I'm not interested in the
legal aspects, just the mechanics, thanks.
