Fault Codes – Any insight appreciated

I just purchased a 2009 X5 E70 N62 from an auction. It appears to have some water damage from the rear sunroof drains / boots. The ABS / Brake / Traction / CEL and Steering Angle warnings are lit along with the electrical system malfunction in the central display. I have installed a new battery (92 AH) and have completely cleaned the rear fuse panel and all connectors on passenger’s side with contact cleaner, etc. I also cleaned the corroded contacts on the ATC 700 module but it maybe shot.

I have just scanned it with a Bavarian Technic Tool and got the following:

Does anyone have a link to BMW specific fault code definitions?

Has anyone experienced any of these and does it seem like the ATC 700 is shot?

Any help or insight would be greatly appreciated.

Sounds like a flood car. What makes you think it was sunroof?

There are no signs of corrosion / water damage anywhere but the trunk, also Carfax was clean, no reported flood damage.

What codes lead you to believe it is a flood car? Would you happen to know what Can / Fault codes are thrown when the Transfer Case Module is bad?

It's the cumulative list that gives the impression of a flood car. Clear everything and see what comes back. Will give you an idea of what relays, fuses, and modules are left to check. Much of your list is no longer present which can mean a few things. 1 your cleaning brought back a module/relay or two in terms of functionality. Or 2 those are historic codes than have been remedied at some point in the past.

I just went through this exact same thing with an E61. Started with something like 50 errors. Needed some relays and a module or two. Have it down to 1 error with the IHKA, but it's a "present" error which is related to something in the unit itself.

Edit: BTW, there is no such thing as a cheap BMW. Bought our wagon for $1200 and have about $2500 in it currently catching up on maintenance, missing parts, and general neglect from previous owners.

I will try to research a resolution for these fault codes but I will start by replacing the Transfer Case Module (ATC 700) as I am thinking that is the culprit for many of these codes.

Really looking forward to getting this X5 going, I have always adored this body style and will go over it with a fine tooth comb. Many of my other cars have needed tons of TLC as well, so I am prepared for whatever this one can throw my way.

Sounds like you’re alternator is going bad. Undervoltage/overvoltage=bad alternator. Replace it and be happy. I had similar issues, it’s fixed after replacement. Also make sure you register the battery to the car with the right software. Hope it helps. $350 for new alternator plus labor around $120.

There are a ton of parts that- if they fail due to water damage- can in turn damage up- and down-stream components..


Like , IBS cable, Junction Box (JBE)... these cars have modules that hang on various busses, waiting for control signals and voltages to hit certain numbers. If the control is hosed, you can get these 'christmas tree' error reports. Check out your ground straps too.


There is a reason this car showed up at auction..... I actually recall a doctor (MD) who bought a brand new X5 and brand new 535 from Sandy. Figured it would be a fun project. He didnt have a code reader; didnt have ISTA...didnt know how to read BMW schematics. Figured he would just take it all apart and clean contacts.



If you ever need a neurosurgeon in NJ, I know someone you should NOT see....
