throttle body service on 2000 Jaguar S-Type

my car has 80,000 miles and runs great. When I got my car back from local JAG dealer for regular oil change the sent me a letter saying I need a throttle body service. No problem I can detect. What do I do and are they drumming up business? I have no yellow light or drivability issues.

Cleaning the throttle body is a good idea as a part of regular maintenance, and our technicians often recommend it to keep your car running perfectly. Normally, a shop will recommend it when you are in for service and they determine that it's time for a cleaning.

You can probably wait until your next oil service--you're not going to suddenly start experience problems if you don't do the service, but it is a good idea in general.

Some of the throttle bodies gave problem (illumination of the Check Engine Light, stalling ect...)on the earlier S-Types. Jaguar don't recommend "cleaning the throttle housings. Do you have drivability issues or the yellow Check Engine Light on?

Yes and my Restricted performance light comes on, and it has transmission faulty, and the engine light is on...But it goes out after a while....I was suggested to get the throttle body cleaned first
