Active sway bar disabled - codes
Yesterday I got the dreaded red suspension icon and warning message. I had been doing some light off-roading in Lerderderg and was on a reasonable gravel track at the time. Codes are U0343 and C1119. Vehicle drives OK, fluids, etc all good. No leaks or bad noises. Active part of the sway bar appears to be non-functional, ie the sway bar actuators are locked and dumb. No longer sits dead flat cornering, actually leans slightly. I dropped past my Indy at closing time on the way home and they weren't quite sure what was going on and were going to research further, however they showed me that the reported system pressure at idle didn't meet the demanded value (just under - 1.9 bar vs 2.0 bar). Builds pressure aggressively when revved even slightly. Code/warning/etc comes back immediately after clearing, not after the usual diagnostic check time. Indy was confident no damage was being done driving it, which is good as it's my daily.
I changed the ACE filter last night just in case that was causing a restriction but the old one was clean and clear and the issue is the same today.
Any thoughts? I'm leaning towards a dodgy pressure sensor at this initial stage or potentially a bypass bleeding off slightly but not really sure?
