Re: Black smoke arrives

Fellow audi fanatic,
    black smoke means that the engine is getting too much gas.  Check the
codes from the computer.  Also check the turbo pressure hoses and check the
output from the computer to the OXS frequency valve.
    I had this problem back in the summer, it turned out that the transistor
in the computer which controls this valve was burned due to bad solder
connections in the fuel pump relay.  I replaced the transistor in the
computer and resoldered the fuel pump relay and all was well again, total
cost $8.00 cdn.  Good luck.
