Indeed. I'm using an OBD reader with alarms since a few years. A complete, uninterupted regen takes 500 or 540 seconds (I still don't know). However it does not take much releasing off the throttle to see the temp dropping to below 450.

I don't understand what BMW does here. I had for example intake temp (after intercooler), but then lost it after dealer did s/w update. Not knowing when a regen takes place would not please me.
An alternative (but less reliable) method is seeing if you have access to "Requested EGR %". With ambients above 0 C, and on a 320d, EGR is being requested up to 140 kph / 2400 rpm steady speed. I fear that might be higher on a 335d as it should be load/displacement related. That requested EGR % becomes zero during a regen, so no (unburned) fuel goes thru the EGR system back to the intake. But it is also zero during accelerations..
