Which is the correct part number for the AEB/AJL ?? 1.028115105M 2.058115105CALT 3.058115105C as my light came on again the other day after being in traffic for 5 minutes after getting off the motorway then went off as i pulled on the roundabout ?? Do you think it could be pressure switch playing up not plumed in a pressure gauge yet but thats on the list to do !!
