Happy new year all. Right, the temp in hertfordshire England is -3 to 6 C at the moment and the car is showing a pressure loss in OSR - 27 instead of 37. I went around and checked and adjusted all the pressures and all was well. The next day we had to go over to Aylesbury, 50 mls. Starting up, the pressure warning came up again so I stopped off via our local tyre guys to check - all spot on and the warning went away. The technician said that the cold weather sometimes triggers these faults. Today, 7 C and Low pressure warning again even though the pressures are correct. Has anybody else witnessed this and what was the fix please? Thanks. Clive.
