    Default Drop in MPG after doing a few things to my car

    Hey guys,
    about 3 weeks ago i changed my front brake pads and cleaned my MAP sensor(Boost sensor) but now i ive noticed a drop in my MPG.At one point i was only getting i was only getting 44 miles to £10 but that has slowly increased but not to what i was getting before

    I thought it may of been the brakes binding but the wheels spin freely when off the ground so i can only think it maybe the boost sensor? The car drives perfect so im a bit confused to why it suddenly changed.

    Its a 1.9cdti 150 engine

    Well that sensor is used to calculate (along with other inputs the correct amount of fuel to air) so I would say its possible its been damaged during cleaning or not cleaned enough.
