Back to WMSS for a service this time.
They checked the charging and found it to be ok, guess the slightly lower voltages are fine.
Had the front droplink bushes (whatever they are) changed to poly as part of my stiffening policy.
Oil, filter and plugs all changed.
The adjusting mechanism in the O/S headlamp was apparently a bit loose, so they sorted that.
Had a new central locking motor for the passenger side rear door.
And had the air-con re-gassed. It was working ok before, but apparently it was a bit low on refrigerant.
