Ranger Mods

Hi All,
I have a 2016 Everest Titanium. Purchased earlier this year. It has 230,000km on the clock and came with a number of faults:
EGR cooler leaking Water into inlet - replaced,
Timing cover oil leak,
Rear diff leak,
Parking sensors wrong type apparently. Still waiting for the dealer to get the right ones in and painted. Only been 3 months still.
Windscreen washer pump not pumping. Blocked perhaps?
Front left light washer disconnected from its mount and dropping down. Cover lost.
Intermittent fault with the AdBlue heater A. Sometimes there is a really bad smell that makes people's eyes water coming from the exhaust.

Bought an MX+ adapted to play with the settings.
