hi, i am new to Mercedes as i bought this car 6 months before. it got full Merc service history and it has done 130k on the clock. yesterday engine management light turn up and i went to local mechanic and he plug inn the computer and it shows lots of error codes. he reset the light but it came back up after couple of hours. i went to him next day and he plug the machine and it came with Error Codes P0135, P0340, P0410. he believe it is my Camshaft sensor P0340 which is fault and causing the other two to fail as well. is it make sense or any body have any idea what is the exact problem. thanks
