Hi mate yes fantastic little tool highly recommend it working perfectly for regens however you must make sure that all the parameters are met or the vehicle won't regen. If there fault codes it may not regen as these could in some way be linked to regen. I have regenerated ford Kuga, Volvo S60 and a Peugeot partner so far.

You may well have a dirty/ semi blocked dpf if the vehicle has faults there is a high chance regeneration will fail and could well be why it has so far given problems, please remember to change oil after regeneration as it can contaminate oil. So first find the cause of faults repair those and then try regeneration otherwise you will have same issue every time Hope this helps. If I can assist any more please let me know.

It has a brake function I'm confident it would

I am confident it will using the live data function however some of these functions are vehicle manufacturer dependent and the tool may be able to but the ECU may not on the vehicle
