Hello!
I´m here to know if the owners of CLX with engine 1.6 ecotec D with 99hp have noticed some small vibration on 3rd gear between 1250-1500rpm, only between this rpm I notice some vibration and different sound coming from the engine, with rpm raises the sound is gone. In 2nd, 4th and 5th gear in same rpm range I dont notice anything...it is very strange, my CLX only has 2600kms +\-.
Maybe it will be difficult to have some feedback, I notice that almost all of diesel CLX in here are the 120hp, I choose the 99hp due to kind of daily route that the car would make and also the difference of €, in Portugal the price of cars is RIDICULOUS due to the taxes 
Thanks!
