Parts list and drawings for S Type Jaguar

Thank you for asking me to help you with your problem. However, I am an auto technician. This question is not within my area of expertise.

First try to find a Good Independent Jaguar specialist, as these tend to give much better service on difficult problems than the main dealers who always seem to just want to put new parts on your car and give you a massive Bill ! Fail safe mode can be caused by many things. faulty temp sensor - throttle position sensor - air flow sensors- faulty coils - the list is endless ! Get the codes read on your car by a specialist - this history will show areas where the fault lies. If the codes are not too clear a running monitor test on your car when in use can help to identify the problem area. But make sure you take it to a GOOD garage ! Don't panic as the fact that the car is still drivable and the fault resets when restarted shows that the problem is in one of the electronic sensors - components or could even be a corroded wire in a cable loom. There is a list of known problem areas and reoccurring faults that will be known or accessible to a Jag specialist or Good Garage. Hope this helps - good luck.

For a basic "tune-up," the rates as low as $30-$50 in places where the cost of living is low, to as much as $100 or more in expensive areas where more is included in the tune-up.
Most places will charge you for parts and labor separately. Often tune-up parts like spark plugs, air filters and fuel filters will run $20-$60. The hourly labor quotes are from $40 an hour, to over $110-$150 an hour at BMW and Mercedes dealerships in urban areas. In the San Francisco Bay Area, the ordinary repair shops charge rates from $55-$80 an hour, and ordinary dealerships rates of $80-$90.
Dealer 30k, 60k or 90k mile tune-ups can run from $250 for 3-4 hours of labor and basic maintenance, to over $1,000 at places with high labor costs and additional maintenance services, such as timing belt replacement.
If the mechanic identifies needed repairs, this can add a significant amount to your total.
