Name is***** goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,
You need to get hooked up to a diagnostic scan tool and check for malfunction codes ,
You need to see what the cause is that is tripping on the warning lights.
Just had one come in the shop and found that the fuel pressure regulator had failed , not saying this is your issue but with a
scan and check for codes will put you on the right track .
Also seen MAP sensors cause issue like this so a scan is needed don't want you throwing parts at your car could get expensive .
Then if needed please get back to me with the reply button, and not the poor or bad service, this way i can get back to you or suggest another expert if needed.

thanks did all this and was told that emission filter in exchaust is 68 percent blocked .put this special fluid in exchaust as told but it hasent solved the problem

Hi 'If a forced regen has not worked also then the system need exhaust replacing .No way round this , unless you have a good shop that can remove this system and reprogram your ECM to run without it... By the way, the fluid that you use only works on exhaust system with under 25% blockage and some times not at all.Rgds Greg
