So I got 2 faults for the valvetronic which were:
Valvetronic high voltage, shortage to ground.
I recently replaced both valvetronic lift motors and both valvetronic sensors my battery is new and my alternator is a year old. I also recently replaced my DME and MPM. My Indy told me there is an SIB for a retrofit of some ground wires for the 2 valvetronic lift motors. I'm hoping maybe someone with more knowledge than me can shed some light on this problem and maybe other fixes. At this point I'm about ready to take a dreaded visit to the stealer. Any input would be appreciated

are you referring to the servo motors on the top of the intakes? if that's them, just follow their connector and look at the ground. doesn't sound like a backbreaker.

Engine: Custom Remus cat-back exhaust w/chrome square tips, K&N Air Filter, Charcoal Filter Removed, Sprint Booster :-), 50/50 mix of 91+100 Octane, EuroRev ECU Remap (coming soon lol), Dinan High-Flow Throttle Body (coming soon...maybe lol)
Interior: Portable Sirius Stilletto 100 w/car kit, Garmin Nuvi 680 mounted below rear-view mirror, LCI-style I-drive knob, Dark Poplar Center Dashboard Trim.
Exterior: E60 forum clings, 5% rear tint, ACS roof spoiler (painted black for distinct look against limo tint), ACS trunk spoiler, ACS add-on front spoiler and rear apron (awaiting installation), "18 Black Staggered BeBeS Style OER (emergency replacement for cracked sport 124 rims), black kidney grill, white accessory lighting (including license and trunk lamps), Angel-eye upgrade, AIB xenon-matched fog lamps, AIB V3's on order, red rear reflectors
Very carefully check the pin connections on the computer modules. Its very easy to bend them. A simple swap shouldn't have been problematic, at least as voltages are concerned. Pay particular attention to the Integrated Supply Module (the black box with the exposed fuses). Check the fuses! When you attempt to reset adaptation values, do you hear them cycle at all?

The intergrated supply module was changed as well could you direct me to where it's located so I can check the fuses. Also how would I myself attempt to reset the adaption values? How do I know if this was done? What if it wasn't would that throw the codes as well?

If the fuse or pin connector on the ISM that relates to the Valvetronic motor control is blown or bent, you'll get the error you are experiencing. IF you have INPA, you can reset adaptation values from there. I think you can do it within DIS as well. If you aren't sure what I am talking about, try to find someone in your area who performs car coding, if possible. If not, start in the beginners lounge on this site--->BMW Coding

No need to replace the fuses if they're not blown. A fuse is a fuse. If the adaption values were not reset after the replacement then you're going to get some errors. Adaption values should always be reset and both error and info memory needs to be deleted
