If there is a ticking noise on the engine it may be that your engines hydrolic valve lifter's may be failing. The reason why it may be a running problem is that the valve lifters are part the VANOS system witch is BMW's answer for variable valve timing. you have the M44B19 engine witch only has VANOS on the intake cam shaft. I cant be shure with the infomormation I have if this looks right and you require more assistance.
