Hi All

I have the dreaded NoX issues with my car but it's started not reaching 6th or 7th gear and not kicking down, like Limp Mode. Could this be related to the NoX sensor/emission system?


Thanks in advance

Unfortunately it's difficult to tell without reading the fault codes.... hopefully it's not the AdBlue system.

Thank you for the reply. Could the AdBlue system cause this to happen?. Its got 20ltrs of the stuff in the tank

Its impossible to say. It needs proper diagnosis with the right equipment and operator.
