Ok, I have made several modifications to my 2013 E350 Bluetec and am having problems getting her to run right. I had a tune put on that would delete the DPF, CAT, Adblue, Swirl flaps, etc. I did the same to my 2009 GL 320 and it worked great. I don't think my problem is the tune I think it is related to something I might of messed up while doing the oil cooler seal changeout.

Anyway, I am struggling with my iCarSoft scanner and cant figure out what is going on. If I had to get the Star Diagnostic tool where is the most reliable place to buy outside of Mercedes? This is a lot of money and makes me VERY nervous.

Dump the tune Biff

Unfortunately, not an option. I needed the tune to delete the problematic exhaust issues. I now have a straight pipe exhaust. No going back. Not sure the problem is the tune. It might be a mechanical issue with my re-assembly but the iCarsoft scanner is being less then helpful with diagnostic.

Update, I reinstalled the swirl valve actuator (Swirl valves are gone and the holes welded up) and the EGR pipe between the exhaust and EGR valve (removed the CB Engineering delete plate) so the EGT sensor would be back in its original position. The car runs really really good but still have CEL. Unbelievable how well it pulls.

I purchased mine from this store on aliexpress, took it apart to make sure the electronics were as advertised and has worked great. SD Connect C4
You will also need a subscription to either ******* dotCom or CarTechnology dotCOdotUK to get the software -- I recommend the latter cartechnology site if you had to pick one but they have both been invaluable to me.

I have other posts here regarding this
