My car got flooded completely.
 

Hii Everyone,


I have a Jaguar XF supercharged 2009 model, which got flooded due to heavy rain fall in our country, Well I need some help to start up my car I hope you guys would defiantly help me. I have few question please help with this.

1. My Key remote is not working.
2. My car is not starting and I am unable to open up the car as well.
3. Child lock its not operating by the key remote.

This is the S-type section which is a different model that your car.

It is probable that many of the car's computers are damaged from the flood waters. The car will not operate properly until they are dried, tested and possibly replaced.

Time to go Jag shopping...

Seems to me you got problem with CAN bus, you need to open car with key blade via driver door, take out front seats, floor carpet, disconnect modules and trying to drying housings and connectors.

Using key blade, open trunk and disconnect battery.

Yes you need to open the car with the key blade as stated above.
Air dry it as much as possible.
You say it was flooded by heavy rain, but does this mean the rain got into the car somehow by falling on it and penetrating seals or through an open window or was it submerged in flood waters?

If it was submerged, the rule of thumb insurers use in that if the car has been submerged to the door sills, they will write it off. (too damaged to repair)

A completely inundated electrical system is almost impossible to dry completely due to water penetrating the electrical conduits and even if you do get it going, they will almost certainly corrode and break down later on.

If it's just been wet from above then making sure the ECU etc is dried out and liberal use of WD40 or some other water displacement oil on connectors etc could get it going.
