Default TCU Boogie
Where on my 97 A8 4.2L is the TCU? Car went into limp mode last night, but we've had terrific rain here in NW, so I want to see if it got drenched.

Default Re: phlenum opposite side from ECU
THe plenums don't appear to be clogged, but I think they are slow to drain. So where is the TCU located?

Default Pinch your fenderwell nipples, and then when you have time, blow out the hidden firewall nipples.
To complete the "HOLY CRAP, there's water pouring into my A8" trinity, also clear the AC evap drain nipples on the interior transmission hump.
