e400 coupe

Hi all, just after some advice I’ve had my E400d coupe for a year and now the warranty is expired, I’m seriously considering a stage 1 remap as I’ve heard these engines can take it long term. Most companies are reporting gains of 335 to 380 bhp, 700 to 820nm torque and a rough 10% gain on mpg...

Hi, I've recently become a member. I own a 2014 E400 Coupe with 50k miles which I intend to keep for the a few years (picture attached). Would appreciate any pointers as to likely issues or servicing I'm likely to need to attend to the next few years...... or any feedback, come to that. Dave
