Intermittent faults showing on diagnostics

[eddie_delaine826]

I recently took my 2010 XF to a local independent Jaguar garage to get a parking sensor rectified. When the diagnostics were run it showed up four unrelated intermittent faults with functions that I have had no problems with thus far. Is this an indication that these errors are likely to develop into actual faults in the foreseeable future with either, as a minimum, sensors needing to be replaced, or at worst wiring or associated systems/control units failing? If I multiply the cost of getting the parking sensors sorted out by four I have to think seriously about getting rid of the car before I end up spending more than it's worth.

Any thoughts/experience would be welcome.
