Two 25 litre containers at home cheap as chips. Windscreen Wash and Adblu. That’s right. I put 25 litres of WW into the adblu tank😡😡😡With help from Halfords bought a pump that works off the drill, . All pumped out this morning. Ignition not been turned on nor engine started. Waiting for my local mechanic and his lap top , Tank remains empty pending his advice. You can only reach the drain plug by removing the massive exhaust box. Well peed off
