How often can I do forced regeneration?

No, but why would you want to? It should be doing regens by itself as often as it needs to.

 

I think he could do damage.
Overheating the DPF and cracking the ceramic filters.

if you do regen very often you will lower lifespan of dpf filters..

 

That device is junk Here are the reasons why... It doesn't tell you the codes. If you require a FORCED REGEN you have something going on... The truck shouldn't require a forced regen.. Also doing more regens does nothing but ruin the DPF filter. You should invest in getting the software so you can see Temps and whats going on

 

You can pull up the codes for Volvo in the diagnostic menu on the dash without any tools, write them down and research them, then reset the codes. If you can go a few hundred miles before it derates, then you can reset the code and go a few hundred more and repeat until you can fix it.

The fuel mileage you gain by having your filters cleaned through a regen is probably wasted by performing the regen. In my opinion, you're taking a risk that your filter will become damaged by excessive heat too often. If it asks for a parked regen, but I choose to reset it instead, then I would force a regen later when I have the time to perform it.

Sometimes I get codes that pop up in cold weather that clear themselves after driving for a bit. I would rather use the OTR tool to reset them than to potentially get derated. It is better than unplugging the speed sensor, since your jakes will not work, you lose power (can't build as much boost), and E-logs will not switch to the drive line. The alternative is to take it into the shop and have them charge me $400 just to possibly tell me they don't know what the problem is.
