That product is for accumulated soot not ash. More than likely a forced regen without it would have done the same thing.
Replying to an old post, since I'm going through this thread for the first time.That is good news, and consistent with the many reports on the DPF data collection thread, two over 200kmiles/200 ml and tadurkee's report of 300 ml before she lost her car in an accident.
My soot count per dealer tech was high (45?) Pretty sure my turbo is leaking oil, increasing dirty combustion and 'clogging' the dpf. But tail pipe is quite clean. My mpg has not suffered. I dont get it. See pictures. I cleaned out throttle plate. Egr valves. And some of intake. But i suspect it will continue until i remedy the source. I did also use the Würth cleaner. Through the upper level O2 bung, stain on driveway was all that was the result, no smoke on start up or under hard acceleration. See link for photos.

I have now had my DPF filter cleaned twice and while so far the second clean appears to be working I am not confident of its complete success. I am trying to discover if LR have modified the DPF from its initial fittment in the Velar and if so does anyone have any information on the changes? What have other members had to pay for a replacement DPF. I see from surfing the Internet there are a number of companies offering to replace DPF units and it seems their prices vary enormously from the "genuine LR dealer prices"Never seen a TDI DPF that was clogged and needed "cleaning".
Seen plenty of 'em cracked and leaking internally, though. No cleaning is going to fix that.
So at this point, I'd say this discussion is useless.
FWIW, I have four CR TDI customers with over 200k miles. None of those have clogged up a DPF. We are doing one on a Sprinter this week (replacing, not cleaning), and it went 440k miles. The fleet management company that controls the pursestrings for this particular vehicle doesn't allow cleaning on lighter duty stuff, because it is labor intensive and doesn't last.
On the TDIs, given the work involved to R&R the DPF Fixer, and the relative low cost of them on the 4 cylinder cars (with the exception of the as-built 2009 models), and their tendency to NOT clog, and instead CRACK, I'd say cleaning them is probably not the wisest choice.
Now on big trucks, and farm equipment, etc. where the DPF is typically out in the open and easily removed, AND a replacement that costs THOUSANDS of dollars? Yeah, clean them all you want. That makes sense. But on little Volkswagen? Nah.
