I have Mitchell On Demand Repair CD and the Jaguar Factoy Service Manual Data CD and neither cover removal of the supercharger. I would appreciate any information on this job. I have a clicking or knocking in the supercharger when idling. I called Eaton and they refered me to PSE which does the rebuilding on the unit. They indicated to me that a number of 2003s had a problem with a spring breaking in the coupling in the gear head. I need to pull the unit and send it to them for repair. The car has 13K miles but is out of warranty due to age.

This is the procedure for 2003 XKR.

 

at 13 k never seen that before are sure it's the supercharger ? If it was broken with that little mileage jag can still cover it even thou ur out of warranty

 

Thanks for posting the procedure, I was able to find the procedure in my Jaguar Factory Service Manual after reading your procedure. I guess I just hadn't learned how to navigate the CD and find the information. I think I have got it now.

 

Regarding the 13K miles, I would have thought that Jaguar would have covered this problem. I talked to Eaton and they sent me to PSE and after hearing my description of the problem, knew exactly what was broken. They have had to repair a number of 2003 Jajuar superchargers for this same problem. I can understand why Jaguar would not want to make a recall on this issue. It would be very expensive. The dealer does not repairthe supercharger but replaces it with a new one when there is a problem. I am sure the cost would be over $2K. I can pull the supercharger and have it repaired for under $200 if my time is free. It would be nice if Jaguar would pay for the repairs and a little for my time.

I just got an email from a member of this fourm saying that I should be covered under the emision part of the warranty. I will have to check on this. I had a problem with a fuel pump on a 1994 years ago and the service manager called to my attention that even though my regular warranty had expired, I was covered under the emision warranty. I have had four Jaguars, 1994 XJ6, 1999 XJR, 2002 XJR, & 2003 XJR and have had execelent service from my dealer. However a dealer is only as good as the service manager and the mechanics and they were tops. Our dealer has lost this service manager who was just super and I no longer have any special treatment.

These internet fourms are just great and this seems to be a really good one.

Thanks to all, Ernie

 

I went to see the dealer again and asked them to contact Jaguar to see if the supercharger is covered under the California emission waranty. They said it was and put a new supercharger on my car. I would have been happy to have the supercharger repaired but they just put a new one on the car. All is well that ends well.

 

That's perhaps the only good thing about having a car in California. This save me quite a bit of money on replacement of the optispark distributor on my 95 Corvette when it died after the normal and extended warranty that I had on the car. The 7 year/70,000 emissions warranty kicked in and it cost me nothing.

There are a bunch of items that are covered under the emissions warranty even after the standard warranty has expired.
