Hello Scotty, how is everything? I have two questions for you mate, if you can help me. The first one is for BMW E87, series 1, 2007, hatchback, petrol, manual, 300000km. When Iam changing from second gear to third and from third to fourth gear I hear a noise like "grgrgrgr". I can hear very little this noise. I went to a lot of mechanics, some they told me is the gearbox other told me that is the rear differential. The noise I'm hearing is when all the pedals are free, meaning neither pressing clutch or petrol for 2-3 seconds and stops. I changed the gearbox oil and it was clean but still I could hear the noise. Yesterday I changed the rear differential oil and it was awful, black and difficult to come out. The noise is lesser but Im still can hear a little bit noise. What's your opinion for me to do? The second question is about a Mercedes c200 CGI, AUTOMATIC, 2010,petrol. When is changing from first to second gear there is a strong noise and like something is hiting from behind. Only one time makes it every day at my first drive even is morning or afternoon. What do you think Scotty? And the last one....I'm thinking to buy Toyota Yaris. What year is the best model with lesser mechanical problems and economic fuel consumption?
Thanks for your valuable time Scotty
