Hello everyone, I'm Roberto from Spain, I and my car is german, 124,133 / 603,960 Mercedes 300D Turbo 1990. Excuse me, my english is very poor (Google translator help me) but I try to communicate with other living beings of the same species, especially with fans of this lovely hobby - german cars. I have a doubt with this:What is this? If anyone knows please clarify my doubt and second is that because my car was going very slowly I removed the valve of overload protection and I regulated Alda. My car now is another very distinct quick response is much more than before, the automatic gerbox switches change much faster and thinner. My question is: Could this cause any negative effect on the engine and automatic gearbox? Thanks for the replies
