Power Steering Issue

[o2bad455]

Progress: The result was 7.7 ohms between pins 1 and 2 (looked like a blue and a green wire, respectively) at the SVT module connector behind the glovebox. Assuming that's the actual resistance at the servotronic valve itself, does anyone know if it's within spec? I do have some manuals (possibly just for E30 and/or E53 rather than E83 - can't remember) but they're elsewhere. I'd read on another forum that 4 ohms was good but 7 ohms was bad, but that might be for a different part number.

Where might I find the correct servotronic valve part number for this 1/2008 E83? FCP (my usual go-to) lists one for just about every other BMW except E83 X3.

Procedure: I scanned for fault codes, then disconnected the battery (is there a way to reopen the hatch without power?), got the glove box apart (much different than write-ups so they must have changed it for LCI - mine used phillips rather than torx), and tested the impedance (technically just resistance) between pins 1 and 2 (looks like a blue and a green wire) at the SVT module connector.

This time fault codes were as follows (still no SVT fault and showed green on the tree page, although there is a DSC fault showing and that showed yellow on the tree page):

000004 LWS: Slider fault (adjustment operation) -1
000004 RDC: Wheel detection not possible -1
00002E RDC: Wheel electronics, front left: no reception -1
000031 RDC: Wheel electronics, front right: no reception -1
000034 RDC: Wheel electronics, rear left: no reception -1
000037 RDC: Wheel electronics, rear right: no reception -1
0000BE KOMBI: Data-filing difference to central light module -1
0000A3 MRS: No message from DSC control unit or message incorrect -1
0000A1 MRS: No message from DSC control unit or message incorrect -1
00003C LM: Number-plate light faulty -1
006E3D DSC: Steering-angle sensor, internal (mileage in km)
00578E EGS: Gearbox oil: wear (mileage in km)
