High pressure injectors (especially in a diesel) make a very similar sound to noisy tappets.

Mine's a petrol engine and the MB specialist told me to use higher quality fuel to cure this. Injector nozzles getting a little clogged up causing the higher tapping noise.

I went back to using Shell V Power and the issue is gone now. I've moved a couple of years ago and started using the local ESSO superunleaded in the last year. The car seems happier with V Power or Tesco Momentum.

Thank you for the tip on v power. I am on half a tank of sainsburys regular so will switch to V Power. I used to get MPG with V Power too.,
