DPF Cleaner-any good?
DPF Warning light on?
You may or may not be aware that Diesel cars now have fitted an item called a DPF (Diesel Particulate Filter). What this does is help to clean up diesel emissions, and they do it very well as most modern diesel cars have almost zero emissions.

Jeep Cherokee O2 Sensor issue
Well this one threw me I have to say! Jeep Cherokee 2.4 petrol came in with the Engine Management light on.
Code reader came up with code P0133 which relates to O2 sensor bank 1 sensor 1. Tested readings from sensor which were all ok. A brief check over revealed no issues, so suspecting just a “spike” in the system I cleared the code and road tested, all OK.
