I live in the Boston area and need a really good VW diesel mechanic preferably on the North Shore. I brought my car to the dealer and they attempted a forced regen which didn't do anything. Then I brought it to a mechanic who is pressure cleaning the filter without removing it. I have to drive about 100 miles and then bring it back to him so he can put more cleaner in and repeat. My inspection is way past due. I've already gotten a ticket! I need a really good mechanic who can troubleshoot the problem. I've researched this enough to know that it could be other things, like the thermostat, etc. I need someone who can actually figure out why the light is on. I filed a complaint with VW NA and they haven't done squat. It's out of warranty. Thanks!
