Mercedes S500L W220
I have a 2000 S500L. Drives ok and had it 2 months. The engine has developed a ticking noise. It sounds like (pardon my amateur engine knowledge) the pistons are catching on something as they turn. Have been told by someone that its something to do with hydraulic 'taps' inside the engine. I've had the oil changed and use V power fuel. The mileage is 140,000miles. High? I don't know, what do you think? I mean they are 5.0 V8 mercedes engines!
Are there any other common problems that I should be aware that may happen in the near future?
Thanking you all.
