This is a discussion on CLA 45 Running in ? within the Mercedes-Benz CLA45 AMG forums, part of the Mercedes-Benz CLA Model Specific Forums category; I am taking delivery of a CLA 45 in November do you recommend running it in or not ?...
By running it in do you mean breaking it in? In that case yes, absolutely! It is very important if you want the full potential of the car to be brought about.
I am going through the pain right now, but essential to do
It's my first new car, my first AMG and I want to look after it. I'm not sure what harm it would do to drive it hard a little earlier than advised but it's not worth any risk in my mind. Guidelines are there for a reason. 2 weeks and I'll be over the marker ready for action....
I also read that its bad to do long journeys on the motorway when running the car in?

Constant speed is fine too, just make sure you are using paddle shifters and alternate between the adequate gear and a gear lower (as many different gears you can utilize without hitting 4500 rpm). Take more frequent stops. This is all for long journey's btw. You will obviously be consuming more gas, but that's how I plan on going between cities because I have to and also doing the break in properly.

I didn't break in my 2017 CLA45... and I did 4.0 0-60 and 4.1 0-60 consistently before 1000 miles and around 2500 miles
