Re: Rumbling from 1991 200 Turbo Quattro
About sending sound files...I forgot to reply to Doyt Echelberger,
we were trying to send them. For Doyt, yes the sound came through
fine. I guess if the idea of sending sound files to assist in a
diagnosis then there are some things to consider:
1. do not post directly to the list. These things can get
big, especially if you're looking to do a stereo half-CD
quality recording in order to pick up a sound clearly.
Sending that to a tonne of people would not keep the
2. Clarity of recording. I guess one will need a good mic
and sound card to get this done properly and to avoid
noise that will mask the sound.
3. Which sound format to use. Most likely be MS-WAV.
Also use the older UUencode mailing format instead of
the base64 stuff, the older is more likely to be supported
by a wider variety of browsers and mailers.
As for the rumbling sound, it could very well be a exhaust part that
has a hole in it or a bracket loose. Last week my exhaust split right
around the pipe, when I launched at a fair speed from the line the
exhaust would be faced with so much gas escaping through the hole
and trying to pass into the still connected bit that it would vibrate
enough to hit gearbox and bodywork and give me sound that had me
thinking my CV joint and bearings had given in. The cause of all of
this was a rubber hanger on the exhaust that had bust off and corrosion
had set into the pipe, the play on the exhaust finally caused it to
