Right, im spitting blood at the moment. I took the A4 to my mechanic today to do an oil change. Im not a muppet but i just could not be bothered to get dirty myself. While they were changing the oil i also bought a new oil level sensor as the warning light came on. Cut a long story short they changed the oil and sensor and i started to drive off home. no more than 100 ft from the garrage the light came back, i did think as it had new oil in i thought it will take a time for everything to circulate so i drove off home. I get home and im a bit mad as the light is still on, so i get the ramps out and decide to take a look. as soon as i take the cover off i see straight away what the problem is, one of the wires to the sensor is damaged and needed a repair. A 2 min job and everything is the way it should be. Now im mad was the guy who changed the sensor in the first plae should of noticed the damaged wire. Just goes to show some times these pople have no clue what they are doing. Im going to give them a call on Monday and give them what for! Needless to say ill be doing this myself drom now on.
