I am extremely pleased that this supplier allowed me to buy a sample HMSensor Urea Doser Pump Sensor. I needed it to try and repair the UREA system on my 2016 Peugeot 2008 BlueHDi, which had the dreaded 3 fail lights come up. IT WORKED, and it saved me about £800 because Peugeot (and garages generally) insist you buy a complete UREA tank unit, which, quite frankly is absurd! Thank you. The wait for delivery was expected but well worth it.
