| Suspension fault. Special Programs off. |
|
Hi folks, looking for a bit of advice please.
2005 D3 TDV6 Auto. Jacked the car up in off road height like I've done many times before to replace the rear prop.
Did the job, put the car back on the ground and got Suspension Fault Special Programs Off message and suspension disabled. It was all working fine before.
Fault code C1A30-64 (AF) Both switches pressed at same time - Algorithm based failure - signal plausibility failure.
I've also got 12.8v at battery terminals but only 11.8v showing on gap tool engine off. It shows 14.8 - 15.0 v with engine running.
I've tried enable EAS on the gap tool and it resets for a second and then the fault comes back again.
Anybody got any ideas please as I'm a bit stumped.

From https://www.disco3.co.uk/gallery/albums/us...284%29.pdf
C1A30-64 Raise and lower switches activated at same time
Possible causes:
BJB Fuse 26E failed Battery box fuse box, 20A
Switch pack harness wiring: short circuit to ground, short circuit to power, high resistance
Switch pack failure
Air suspension control module failure
Action:
Check/replace fuse 26E as necessary.
Refer to the guided diagnostic routine for this code on the approved diagnostic system.
Refer to the warranty policy and procedures manual if a module is suspect
~~~~
Would seem unrelated to the actual switch due to you lifting it, as the wiring between the switch pack and suspension ECU is internal to the car.
Seems most likely the fuse has popped, but why lifting it or replacing the prop has done this is odd, unless you've snagged some wiring somewhere - maybe to a valve. 06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti
