I have heard that the Sprinter vans come with a regen cycle monitor, and that others have found a way to monitor the regen cycle. Both the frequency, and also if it's currently in a cycle.
I have been using the Torque app and when I was having regen issues before the AEM was performed I was able to capture these weird test results. I don't think Torque is accurately naming the events, but I also don't see this test recently.
I also have an Autel scanner but not sure it reads the Mercedes regen codes.
Torque test that failed when regen frequency code was set.
Only last models of Sprinters do have those monitors and for my 2015 Sprinter I am using ScanGauge.
Had SG2 for years, but small display was annoying, so last Christmas I ask Santa for SG3 and it is really nice gauge.
On 1st screen I have DPF load, DPF temperature and DPF regeneration status.
Seems each car has a bit different calibrations, but on my Sprinter regeneration comes when load reaches 100-103% and last for about 12 miles, coming down to 3.
The DPF temperature in normal driving oscillate around 400F, when during regeneration it goes to high 500's.
Since now I have AEM warranty on my Bluetecs, I am testing my sedan in city regenerations. Seems it will regenerate in city traffic just fine, but than I am in warm climate.
