Hi I have a C280 auto and it has developed a fault. Here we go then, a noise that sounds like a bird (chirping) under the dash on the n/s when the noise stops it sets off the vac pump in the boot, it only apears to happen when using the throttle and has a timed pattern, has any one come across this before. It is not the song chirpy chirpy cheap cheap on replay lol. regards Steve.
