new to W208 - fault code help
HI all
Just picked up a W208 convertible - 2001.
I had a BAS and ABS light fault when I bought the car and the vendor told me that he believed it was a faulty Yaw sensor
I bought an Icarsoft reader with the 38 pin adaptor and did indeed get a fault code relating to the Yaw sensor
Ive changed the yaw sensor (what a mission!) and cleared the codes. Pleased to say that he BAS light has not gone out but the ABS remains.
I rescanned the car but the only code I get in the brake menu is:
C1210-064 "State: Current and Historic Road Test : active"
Anyone know what this means?
i havent driven the car on the road as it's not currently MOTd. Is this something that might clear with a road test? Is that what it means?
I was expecting to see some codes relating to ABS wheel speed sensors, or ABS module, but there is nothing....
Any help would be greatly appreciated - repeat, the BAS light is now out - just the ABS light illuminated
Cheers
Simon

I believe the C1210 portion is a low voltage identifier. Maybe the battery is'nt fully charged due to lack of driving? The other part about the road test: I believe its saying literally what it needs. I think it needs like 30 drive cycles to clear ABS faults. Start the car and turn the wheel full left and hold for a second; then full right and then back to center. Then go drive.
I also found this:
1. Vehicle stationary, steering centered, foot off brake, engine running, flat ground, open area about 100' or more across.
2. Press ESP Off; ESP warning light will begin flashing. When it goes solid, proceed.
3. Press brake pedal
4. Shift into D
5. Release brake
6. Begin driving 10-15 mph, steering > 90 deg, < 180 deg. You have to execute about a half turn.
7. When ESP light begins flashing, brake to a stop.
8. Shift to N
9. Release brake
