2.0D Wobble after start-up
Bear with me on this one
In recent weeks, I noticed that my 2014 X1 (2.0D N47T 67k miles) starts fine, after a few seconds, when the initial start up is complete and the idle settles..the engine gives a 'wobble' for about 1-2 seconds and then idles fine afterwards. No codes stored and no other symptoms. I have never noticed this before, but it is not running rough I would suggest either, again no codes stored or present. I did a bit of searching around and people suggested a glow plug issues, however this happened at 19 Deg C outside. The wobble is not exclusive to the morning start, it can happen when we are out and about and the car is left standing for a period of time. In order to clean the system, I have used Chevron Techron D cleaner, to assist with any injector issues (if that is the cause) Has anyone experienced anything similar or suggest what might be wrong? TIA

It may or may not be related. I wish I had more insight for you on the N47, but I have only done this on an M57 and N57 diesel.
My guess is that you are probably starting to see some signs of carbon build up. you can check with a scope, or pop off the throttle inlet and look at the EGR inlet and air metering plate as described in the video. If you see a decent amount of carbon, consider preparing for intake/egr and valve carbon cleaning. It makes quite a big difference. We did ours around 80k miles.

I ran Chevron techron D cleaner (i believe BMW rebottled this as their official cleaner/treatment) through it, it seems to have smoothed out...but I will spend some time on it as per the video and see. Maybe worth a proper engine clean.

They also have what is essentially a throttle body, called an air metering flap, which gets gummed up. You basically need to decide if you want to clean this every 50-75k, or delete and choose parts out. If you decide to clean it, please do a video. There is far too little e84 content out there.
