R230 ABC warning.

[dyver]

Hi, just after your thoughts, Ive a 2007 R230 and replaced the front struts a few years ago with Arnott struts and last year noticed that when I either go over a speed hump slowly or a high speed ‘soft’ dip in the road I get an ABC red warning up for a few seconds, no perceived change in ride and fairly convinced it’s the rear accumulators, tandem pump is the right pressure and no stored codes to help me work it out. Is it worth just changing the accumulators.
thanks in advance
