Hello I want to ask the experts. I am the owner of a Leon Turbo, engine identification letter AUQ, with 180 hp. Since I live here in Mexico on a sea level of 2700 meters, I wanted to ask what the height is with a turbo, especially in connection with chip tuning. Since the air pressure here is almost 800 mbar, an acquaintance who was here once could make me only a small step of an OBD tuning, because apparently the loader would turn to death. What is there about Last year I had an accident, I only got the car in December last year. Since this accident I always have such a grinding noise, taking the gas way. If I drive “normal”, so like everyone else, then you don’t hear the noise either. Is such a kind of metallic grinding. Now I am already very annoying after many workshop stays, because they tell me that the turbo is gone. A It seems that the blades of the turbo should be on the turbogehaeuse, but they never took the turbo apart. I have to say that the chip tuning has only been on it for about 1500 km. And with this noise I have been driving for 10,000 km now, does not get better and not worse. Lt. Workshop is the aftermarket installed pop-off to blame?? Is that possible? Oil consumption I have almost no. Now after almost 12,000 km after the last service, the oil stand is still almost on the Ma Since I don’t know now if I should buy a turbo, I ask here. What I noticed, however, is that the pop-off valve gets very hot, is an aluminium valve, what can it be? I can’t judge if it was already before. You can’t attack it after a normal ride, that’s how hot it gets! I also think the suction bridge is much too hot, not even possible to attack it, and that’s after a normal ride. Is this an effect of The chip tunings? According to the acquaintance I have less than 195 hp and 260 NM. I once read that there are steering gears with an integrated knife, but was, if not everything is only doing for the diesel? So, who knows something about it, urgently need help, because I do not want to destroy my car, but also do not want to invest huge amounts of money… Thanks and beautiful greetings from Mexico Robert
