Question DSC and DBC failure

]Hello all,
Today my DSC and DBC failure warning lights came on , I haven't noticed any difference in the drive or ride of the car since they have, last week I had the magnetic steering lock and column replaced and the car checked on the computer showing all faults cleared, I have noticed that the rear near side wheel does collect a lot more brake dust than the others, any ideas before going to the "Stealers"
Thanks,
Mark.

Could be to do with your steering lock and column replacement, if who ever did it had not calibrated the steering angle sensor correctly or set it up correctly then it would bring up this error, where did you get the work done?

In the short term try turning the steering completely from full left to full right lock a few times.

There are a number of causes for these warning lights to appear. These range from ABS sensors in the hub through steering angle sensor to the ABS/DSC pump/module.

The only way to be certain is to have the codes read.

In my case it was the abs hydro pump unit - a common failure across a number of car makes. This can be very expensive if not under warranty.

I had my unit repaired at ECU Testing.

See my post

The units for 4 cylinder cars seem to be significantly cheaper than for 6 cylinder cars. The repair kit for mine was priced at around £1800 - hence my decision to have the unit rebuilt - with a lifetime warranty.

This happened to me about 3 weeks ago. sensor failed. depending on age of the car, there are repair kits available. I was £270 fitted for the repair kit. Slightly older cars have to have the whole unit replace at anything up to £2000!

Smacg, could you explain which part was faulty, and which repair kit you bought?

My BMW E91 pre-lci, came up with the DSC and DBC errors this week. No matter what I do the won't go away. In the error log I found the following error codes:
A6D1
2A67
9511
5E20
