GT1 readout for DSC problem

My dash lights have been on for the last year and I finally had it read`with a generic reader while replacing my entire cooling system. Code for that came back as unable to connect with steering angle sensor. Replaced it and took it to an indy to get it to talk to the comp and the codes came back as:
1. DME: 0045-multifunction steering wheel interface monitoring..123-Map cooling,204-cc-idle speed leakage air signal impassable.
2. ABS: 07- Left wheel speed signal implacable,{06-same} 20- steering angle
3. EGS: 149-95- can wheel speed implacable
4. ZKE: A4-164- door driver switch
5. LCM oil level
Can anyone offer` insight to what should be changed next? Indy suggested DSC computer and wheel speed sensors but I'm hesitant cause one wheel speed sensor is 1 year old and he wants to replace it because "They have to be done in pairs"
I've had my expansion tank blow up once all over the DSC module and an overflow from the radiator on the module also so dunno if all that coolant may have had a long term effect on the module or not.

Wheel speed sensor does not need to be replaced in pair. Just replace the one that fails. I suggest that replace the failed ABS sensor first and then see if the lights goes off, if not, then try ABS module.

thanks for the input rogerkiu. I knew that they didn't have to be replaced in pairs but thought it was kinda funny that he told me to do that. I replaced one of the sensors last year to see if it made a difference but it never fixed the problem (it was a stab in the dark) and I didn't have access to a reader to see if swapping sides moved the trouble code to the other side. I just pulled out the DSC module last night and saw coolant residue where the plug connects to the module so I'm hoping that this is the culprit. Apparently the DSC module is susceptible to moisture and seeing as my radiator has blown up on it 2 times and the GT1 can't seem to connect to it I'm guessing it seems a good starting point. Great design BMW
sending it to module masters today so hopefully I will have it back in a week and a half. Pray for no speeding tixs since the speedo isn't working after yanking the DSC out

Kinda at wit's end already with this one. Took it back today with a rebuilt ABS module to configure the whole shebang. ABS works perfect but the brand new steering angle sensor shows that it's at 0 but reads 1000. STILL not working!! He said we gotta start tearing everything out component by component to see what's up. He did mention fluctuations with the battery charge but didn't check anything because of time issues. Anyone have any guesses on where to check on the car without just throwing more money at it? I've dropped close to $3000 on this car fixing things in the last 2 months and it still isn't working properly with new problems popping up daily it seems
