Hello,

I own a Mercedes C-class 2015 Diesel estate
It rattled on start up for a few second - was told its the timing chain - took to my local Mercedes specialist - replaced the timing chain - Rattle on start up stopped
Now its just slow on start up almost as if its not going to turn over, garage run some tests and told me its the injector set up, they run some tests and number 4 injector was not reading right, replaced injector, and still have the same issue,
Its almost like its not going to start only difference here is if its cold and I let the speed and RPM gauge needles flick right and left it will start almost first time, once its warm i am back to long starting.

Any ideas?
