Dear forum,
I would like to ask you if there is a detailed list of milage when parts has to be checked, replaced or maintained - or at least checked:
I mean not the regular oil and filter maintenance but the specialities:
spark plugs / coils
injectors,
timing chains, and tensioners,
belts and rolls and tensioners,
water pump,
supercharger oil / bearings
gearbox oil / filter,
rear diff. oil,
etc...
Thx . - Gab

 

Redmen, this is a loaded question as you will find lots of different sources and reasoning behind it. So, this is what I am folllowing:

Spark plugs and coils: PLugs should be changed every 100K miles and coils only as needed due to failure (Coils are good for the life of the engine)
INjuectors: No replacement unless bad (good for hte life of the engine)
Timing chains and tensioners: only replace if creating noise and/or erratic idle (supposed to be good for the life of the engine)
Belts, pulleys, and tensioners: Belt should be replaced every 60K miles and or when it starts showing signs of wear. Pulleys and tensioners are good for the life of the engine.
Water pump: Good for the life of the engine or signs of failure (ie, erratic engine temps and/or leakage coming from the water pump).
supercharger oil/bearings: Not sur eabout this as my car is not equipped with this
gearbox oil/filter: Jaguar says it is a "filled for life" system. If you read other forums about the ZF transmissions, they say that the fluid and filter should be changed every 70K miles. I will be replacing my fluid at 100K miles which falls in line with a lot of other recommendations that you will find.
Rear differential oil: Filled for life and only replaced if showing signs of overheating.
Brake fluid: Every 2 years due to the hydroscopic characteristics of the fluid and minimizing rust build up in the system.
POwer steering fluid: Filled for life.

 

Here is a recommended Maintenance schedule for 2013. I'm not sure if this has changed in the later model years, but as I have a 2013 XJ it is the schedule that I use.
In addition:
Transmission service 70k
Some like to change supercharger fluid @ 70k

 

I would argue that both the differential oil and power steering fluid are not "filled for life." Diff oil should probably be changed every 50-75k miles. Power steering fluid is so easy and cheap to do, I usually swap it out every 2 years.

 

Diff oil , Transmission oil 50-60k miles , supercharged oil 50k miles

 

What about front differential? I have a 2016 F-type R with 43000 miles. It gets serviced every year. Should they have checked the front differential? I've been having excessive road noise and the dealer is telling me I need a new front differential.

 

This is an XJ (x351) forum but: All lubricants need to be changed. There are no difference where it is. Oil molecyles lose their ability to "hold" by temp, pressure and moisture.
Yes: On service the oils should have been checked and changed. Have you serviced your vehicle in same dealer now telling you that you need new diff? If yes, then politelly say them that by 43k miles the diff is not even near of its calculated life, so obiosly there have been mistages in service, what is their responsible.
It´s also an good idea to visit some independed mechanic and ask him to check what the issue might be. (not saying that its common practise, but we have seen that its not uncommon that customers have been "overselled" by dealers. You might just have weared out wheel bearing)

 

You drive a 2010 XJ. If it still has an original water pump, watch for leakage from the weep hole or a temp gauge spike or you smell coolant. The Forum reports that I tracked over the years indicated original water pump seal failures as early as 30K miles to 50K miles. I don't have a calibration on how long the latest replacement water pumps are lasting. One caution all the old sage contributors to this forum will tell you is do not drive your car if you have a coolant failure of any kind. Pull over immediately and shut off the engine. Do not think you can make it another mile or you will kill your engine. Get a tow.

 

Add the rubber diaphragm(s)s for the PCV system. They tear over time and cause issues. There is 1 for the 6 cyl and 2 for the 8 cyl. I would change them every 5 years/75K miles. Definitely change them if you have the supercharger off as it is a 100x easier to do then.
