W204 error messages....

[coventryslk]

Morning,

Not been on here for over 2 years due to personal stuff going on and nonsense I didn't need, or want. I been ok for past 5-6 months now since circumstances changes.

I've had error messages appear in past week or so that had cleared once turn off ignition and on again

They are

Power assisted steering system fault

ABS, EBV, ESP fault

Run Flat Indicator fault


Power steering....stops working etc. What could this be caused by?

 

[LostKiwi]

Most likely a wheel sensor giving a bad signal.
Could be failing sensor, dirty sensor, dirty or damaged wheel reluctor, broken sensor wire.
To be certain (and identify which sensor) it needs codes read with Star or similar.

Booked it in with mercland on Wednesday, see if they can sort it

Hey bud, did you ever get to the bottom of this? Having the exact same issue.

I unplugged the ABS module and plugged it back in and this has gone away. I had read elsewhere that people have had these symptoms (which kick in at around 15 mph) and they have blasted this connector with contact cleaner and had success.

I read the codes with my iCarsoft, of which there were two:

6264: Fault in CAN communication with control unit Engine control module
5001: Control unit N30/4 ( Electronic Stability Program control unit ). Internal Fault.

I'll see how it goes.

Many thanks. Sounds promising.
