We have bought last January a 2013 Mazda CX-5 diesel with 137,000 km.
it now has 141,675km. Last week the engine light, traction control and tyre pressure light come off. It was also jerking while driven. The morning after the warning lights are gone and the jerking stopped. Brought it to the mechanic and found codes for EGR BYPASS COOLER VALVE AND INVALID DATE BETWEEN PCM AND TCM.

The mechanic said not to drive it further and contact Mazda Australia as this is a common fault in Mazda diesels and the possibility of the engine blowing up.
we have a trip coming up travelling atleast 500 km. Thinking if the car is still safe as it’s not showing any warning lights and it drives fine.
hoping to get some insight on this issue and what are my possible option
Well he has a dad a problem so there's a short somewhere either in the computer the wiring or one of the sensors good luck on that that's the real head scratcher you going to need a real mechanic who understands Mazda diesels inside out
