Hello, I drive up a steep hill every day to work, where 100 is allowed, I drive a Twingo, bj 99, 43kw. Now to get up there with 80-90 km/h in order not to hinder the traffic, I switch down shortly before the climb into the 3rd gear. Now my question, do I drive there with 80 km/h in the 3rd gear already in the red speed range? Have no speed indicator. My question is because I have to drive up there every day and want to know whether this is in the long run or already with a few we nigen Malen, which could harm the engine? Thank you for your answers PS: if I ask, I would have a small one ) and I can often not spin my key, can then only move for a short time but not completely, so that the engine starts, must then try 3-4 times until it completely spins.
