Washing the inside

[Oli77]

Yes, how to get the TCU out of there.
Today I spend more time and discovered a liter of water under the battery and a little bit on the left side too below the AMP.
How sooo much water got into the trunk with it closed makes no sense.
The TCU is always on, I can hear it. So it is getting power. I guess it maybe fried.

Needless to say car is in the sun a lot and the inside is now dry.

I just bought a used TCU, the SN is off by 2, made in same city, same software and hardware for sure. It will have to be coded to the car for any sort of communication to occur.

Hoping this is all that was busted by that torrential downpour with top wide open to the skies.

Win!
These 4 plugs, in the front, are a bitch to undo.
Down on the little tab up on the pink stuff and out with fingers.

Good progress here. When do you plan to have the TCU coded?

My regular mechanic does coding.
But In my haste to find something wrong to fix, I did not see the other metal box right below the TCU.
That one has a Bluetooth sign on it and I bet will need replacement as well!
Crap

I might have a BT module if yours needs replacing - let us know what it looks like & any numbers on it.

Thanks John! I am taking it one step at a time and will try the new TCU first. Get it coded and working (hopefully), and then we will see if the BT unit is also toast.
Thanks!

I received the TCU and plugged it in. I couldn't connect one plug, the blue one on the front because that TCU doesn't have a spot for it. But on startup, the message that used to appear about not having SOS telephone sign is gone!

Still no BT. I could try your unit John. Where does it come from? My e93 was built in Nov 2009.

Will take of the BT module and post pics.

Bunch of numbers. mulf2 seems to be a name I recognize from reading forums.
Let me know if I need more pics of the unit @John in VA
