Water in Trunk - No Power Steering (Steering and Chassis Error)

[funkyamish]

2013 BMW 750LI

Long story short, I accidentally left the trunk open over a rainy night.

Luckily I was able to shopvac out the water then dry it up with rice (in tube socks). The battery was fine. I tried cleaning some module connections but I'm still not able to isolate it to which module I should be replacing.

Maybe the "servitronic control unit" or "Steering Column Control Module Unit" #6881834?

I don't know if it needs to be coded either.

I cleared all the codes in the software that I have but I'm trying to line up a time to hook up my friends ISTA’s software up to further diagnose it.

I wasn't getting any helpful codes on Bimmerlink / Bimmercode.

Any help and direction would be greatly appreciated.

Can you post more details about the affected modules.
Did you manage to get any fault code readings?

I haven't hooked up the ISTA’s but I'm getting ready to shortly.

Here are the errors that I'm getting. Sometimes the steering error will turn off sporatically.

"Steering: Drive moderately. Continue driving possible."
"Chassis: Drive moderately. Consult service center."
