    Help! Suspension Issue- B1DB7-93

    I heard a pop sound while queuing to refuel my D5 a few days ago, the suspension stopped working and the ride has been very bumpy ever since.

    I got a diagnosis with code B1DB7-93 Big Cry

    What does this mean please, can anyone help interpret?

    Best regards,

    Mo

    The pop sound I got meant the suspension compressor seal had failed. £600+ for a garage replacement unit. Cheaper if you diy …..or get an indie garage to simply drill out the rivets in the “sealed” unit and fix the inners.

    Thanks Wolfpack, Much appreciated.

    Any direction/ guideline on how to DIY please?

    I just got a £800 quote for replacing with a used compressor and £1400 for a new one.

    Regards,

    I am assuming that’s JLR dealer quotes…….or maybe I am out of touch?

    I got my local indie garage to do it for me a couple of years back, at the same time as a service, as fortuitously it went ‘pop’ 2days before its was due to go in! The actual cost was lost in the total bill but from memory it was only a couple of hours work and a few bits. Send a PM to https://disco5.co.uk/forum/member-tomthumb.html on this forum he had it done recently.

    I would give some of the independent LR garages or 4x4 specialist near you a call.

    @Mod5
    If it’s the compressor pressure valve that’s at fault,
    if your lucky you might hear air escaping from the rear of the boot floor on the o/s after selecting off road hight & closing the doors.

    Otherwise the compressor will have to be removed, drill the casing rivets out to check the condition of the valve & compressor.

    Parts were c£40 (all in £222) & took 90mins to do, well took the indi 90.
    5mins to swap the pressure valve, but 85mins for diagnostics on fault codes / strip down / refit.
