Hi all, i have an intermittant problem with what feels like the abs system being activated at speeds around 2mph. The brake pedal will pulse rapidly/judder. This problem seems to have
come to light since using the air con. The brakes also seem to grab and release slowly when reversing with the air con activated. I have no codes and am lost with what this could be.
Has anyone expeienced similar on a X350 V6 ?

 

I can't say why it would be related to the air conditioning, but typically if the ABS is being activated at low speeds then one of the speed sensors is on its way out. The code may be an ABS specific code which would not trigger a check engine light and unless your code reader can check ABS codes, it would not show up there either.

 

I have the same issue .. low speed pedal judder .. have been told it is a worn ring on ABS Shaft ... very hard to get used replacment .. have been quoted over 280 dor used part that excluded fitting....

I suggest that you examine every reluctor ring for wear, bad corrosion, trapped stones or broken rings.
