Hi
A previous owner swapped the interior of my 2004 X Type from Champagne to black leather. I have an issue with the occupancy sensor as it it making the airbag warning light stay on continuously. I've been told that the sensor in the seat is not compatible with the car and I need to find a champagne coloured interior to remove the sensor and pad to fit into my car.
Does anyone know if this is correct and could I get a bypass unit for it instead?
Would the bypass unit work?

 

I doubt seat color is the problem. It is more likely a wiring issue. First what is the build date for your x-type. The x-type up to March 2004 have the same wiring diagrams. The models with a build date of April 2004 and all later models have a different wiring diagram. The electrical system was updated. Both the front drivers and passenger seats have an occupancy. Do you know which one is the problem.
You need to observe the flashing of the air bag light when first started. It flashes in sequence it will for instance flash twice hesitate and the flash four times would be a code 24. With the flash codes we can tell where to look. Thee flash sequence repeats 3 time before thee light stays on.
When I had a problem it flashed drivers seat and I found that a wire in the socket under the seat had pull loose as it had caught up in the mechanism under the seat and pulled out.

So first try to determine build date. If possible find out the model year the seats came out of. Second get the flash code and post. Last check the sockets under the seat for loose wires.

 

And can you confirm the swapped seats were from an X-Type and not another model or manufacturer?

 

Yes they are X Type original seats

Many thanks for this help. I've checked with Jaguar and the date of manufacture is 19th Dec 2003. The fault code showing up on a code reader is C1414

That code references something about an incorrect restraint module part number, so maybe that is it. Seat hookup might be different in the earlier cars, but I dont know much about it.

 

The official name for this is ‘occupancy sensor’ the last part number for STRs before vin N13089 was XR856952 this replaced XR837898 and XR844490.
Have you tried contacting the official Jaguar Heritage parts?

See this link to the official on-line Jaguar part catalogue. Use your vin number to select the exact part and then use the ‘contact us‘ link to enquire about a part.

They may well be able to help you. But be warned I think this an expensive part. The later one that is still available is £651.51!

 

@Mellow, I doubt your info is much use, this is X type (x400) forum.

 

I read a thread a while back where a guy put 2004+ seats in a earlier than 2004+. He had a problem that he ended up fixing that the newer seats had an additional electrical plug in them that was for the airbag (light).

I'd do a search here on seat replacement and see if you can find it.
