I recently had some coolant work done at a local Jaguar dealership. When I got the car back, it seemed to myself and the wife that the car sits a little higher in the rear. Might they have adjusted it when it was in for service?

Side Note: The car for whatever reason doesn't feel to have the same power as when we took it in for service. Maybe they flashed the computer for the latest update or something? Looking for ideas on both situations.

 

Unless you can run the codes using SDD we really can't help?
I don't know anyway to adjust the rear right height either but maybe it is possible?

If they jacked it up at one end, there is a possibility you are off in ride height. If you drive it for half an hour or so, it should return to normal.

If they gave the ECM a flash, you should see it on the paperwork. I have a no flash cap on my OBDII if I ever have to haul to the dealer.
If you want to, measure the center wheel cap to top of wheel arch in mm. I might be able to find the spec later, forget where I saw that in the service manual.

 

Why would you have "no flash" on the ODB port? As in why would the dealer flash anything other than a service message reminder reset after an oil change etc? And if they had to replace something that needs a flash? Shame the author of this post didn't specify what work he had done to his car.

 

I have a larger crank pulley and tune. Procedure dictates techs will work with service advisors to approve work. This does not always happen.
I reset my own service lights after oil changes, the only reason a dealer would need to connect is to potentially reset BMS. I prefer to force the conversation prior to work rather than rely on individual business processes to "take care of me".
