Hello Grandland X driver, have since March this year bought a Grandland X 1.5 Turbo D,130hp, Ez 5.2020, with just under 17tkm. Since then I have had some problems which have been removed after several workshop visits, e.g. A column coverings, timing belt exchange ink water pump due to roaring noises etc. Now for a few days I have noticed when outside is 0 degrees or colder, when starting the engine has hard start process, but then knocks properly when jumping. If he is starting up, 0,xx seconds later RASSES he would say for about 0.5seconds and then is gone. First oil change was made when the car had just under 17tkm, then I drained all about 10tkm of oil and refilled it.Do something like this because I don’t want to drive 30tkm with the same oil. Now the car has 42tkm. What could that be, chain of camshafts? Are there any problems? Has anyone had such a problem?
