Newbie - E70 X5d

Off the top of my head:

1) Check the engine compartment dividers to see if they are cracked. If/when cracked they can leak water and cause injector failure, particularly number 5. Many people also remove the foam around the injectors to prevent water soaking/rusting around the injectors.

2) As has already been stated, check the operating temperature either with an OBD device such as Carly or via unlocking the instrument panel (Google search will tell you how to do this - involves adding up some of your vin numbers and having a button pushing frenzy while the engine is running). If in 70's or barely reaching 80 (degrees Celsius) change the thermostat.

3) Depending on what the fault is with the SCR system, be aware that people have figured out that you may not need to replace the entire active tank. There is a heater unit that I believe also incorporates the temperature sensors that is available for VW (I think VW, might have been Audi?) cars, but turns out works perfectly for our cars. Also, the active tank and NOX sensors have had the warranties extended to 120K.

4) Main suspension component to consider changing are the front thrust arms (at least that is one common term for them - also called upper/lower control arms).

Good luck, enjoy!
