Has anyone used Comma Diesel D-tox(£15.00) or Comma Diesel Magic(£6.00)? Both are allegedly BMW approved additives. Share your thoughts please. How those compare against each other or against Redex? Or may be all of them are marketing rip offs and any ATF would do the same job.
I read different opinions here some say additives should go in the filter so it goes directly in the injectors, others say - in the fuel tank so it cleans the whole fuel system??? Now, where should it go?
I will be driving more than 1000 miles next week so it will be a good chance to rev the engine and flush some additives through it.
I've done the EGR mod as suggested before. Blocked both the rubber pipe and the outlet just in case. Hope I've done it rihgt. Pics below
