DAF ADBLUE QUALITY...ENGINE POWER REDUCTION? what can it be?

on my travels this week I've a DAF LF euro 6 With Adblue quality issue and Daf lf power reduced issues. With the help of JALTEST From ECLIPSE we can get to the bottom of this hopefully! with various fault codes to do with nox conversion efficiency to low and data validation but too high I'm betting on a NOx sensor issue but I'm not willing to blow hard-earned money on one just yet so I'm going to go through a testing plan to ensure the system is correctly operating first and get to the bottom of this Nox conversion efficiency issue. #daf #lf #adblue #nox #powerreduction Don't forget that if you want a great deal on JALTEST such as 65 POUNDS A WEEK and a free nox sensor tester and test light head over to: http://www.trucktechuk.com/jaltest Did you know Truck Tech UK also has a member-only area!!!!
