compared this med9.1 ecu to the picture of the me7 on here and came up with some educated guesses.

30397      ignition driver (same as me7)
30554      injection driver ? (compared to bosch 30344)
30427      ?
30471      wideband controller ? (compared to bosch 30345)
30522      ?
tle 7209 r           ?
30506      baro sensor/leak detection pump ? (compared to bosch 30380)

pictures are attached. maybe someone else can help?  Smiley
i only guessed based on package type and location on the ecu.
