hello gents

my esp defective visit workshop message kept coming on and noticed my steering wasnt alligned so read up that this could be the cause so went to get that done but still message came up
tried lock to lock on steering with no luck

so decided to do a a diagnostics and came up with

esp- fault nd41 check component n49 (steering angle sensor)
scm steering colum- fault 9334 component n49 (steering angle sensor defective)
sbc sensotronic brake control - c25d9 inspect wheel brakes for mechanical faults

i cant help thinking all these faults are connected and dont know where to start for example inspect wheel brakes how and what do you inpect?
 
Sounds like a nightmare. Good luck with fixing your steed.
 
If you have not read the faults for some time the car will throw up numerous codes.
As you have said the ESP fault connected with N49 is the steering angle sensor and can sometimes be cured by correct resetting of tracking/steering alignment, or correctly refitting steering wheel (if it has been removed)
of course it may also be a faulty steering angle sensor.

Codes are only half the info. You need a Star to do more tests.
 
just an update
i removed the steering wheel and got to the n49 steering angle sensor and disconnected it to i can get the part number and once i did i reconnected everything and since then the esp warning has never come back on and its been 1 week and a bit so finger crossed it stays like that.

anyone who experiences a similar situation try disconnected the sensor and puting it back together and see if it helps/also i have been told to get wheel allignment done because eve if its 5 degrees off that can set the esp warning message up too - i learnt the hard way you cannot do an accurate wheel alignment on mercedes as the need to be weighed ( special machine which u have to put weights in the car before alignment and very few places have it so dont waste your money on basic 4 wheel laser alignment etc etc)
