Operate Solo AdBlue leak

πŸ“ž Called out to an Optare Solo today with emissions warning light on dashboard.

πŸ’‰ Customer stated that vehicle was in limp mode and has a strange odour when hot.

πŸ‘¨β€πŸ« Our diagnostic tool may not be Mercedes own brand but it does work well with Mercedes engines therefore a quick plug in gave us a heads up of what to expect with a low AdBlue pressure fault. The tool will do what a lot of tools won’t, it will remove the vehicle from a limp mode state at the click of a button.

πŸ”Œ Once under the vehicle, full extent of the issue was clear. AdBlue feed from pump to metering unit had failed after a previous repair with push fit connector less than an inch from metering unit. Side of engine block and starter motor covered in crystallised AdBlue.

βœ”οΈ Genuine Mercedes pipe from pump to metering unit ordered and fitted. Vehicle road tested and put back in to service!

A view from below and under the metering unit. Push fit connector just about visible.
Exhaust pipe next to the AdBlue injector.
The dirty snow-looking stuff is crystallised AdBlue.
