Volvo XC70 Cross Country soot filter issue
 

Currently in limp mode, soot filter full warning coming up. Local garage tried 2 regens (didn't work) & have suggested to remove DPF & Provide software based solution. Does anyone have any other ideas or experience of what is being suggested? I've seen companies advertising a service to come out to clean filter - does it actually work? Cost of new filter & labour is astronomical! Thanks in advance for any advice

regen wont happen if all the components that enable it arent working check pressure
sensor egr valve all pipes that connect dpf and dpf temp sensor

dont know how good these are but seems cheap enough
