x300 v x308 bumpers
Am I right in thinking X308 bumpers fit straight on to an X300 ? 
My rear bumper is being sprayed shortly was going to swap it out for a later if I can source one if it goes straight on. May as well get the later model one sprayed instead of mine and bin mine.
Will obvously do the front as well

My XJ6R has X308 bumpers. The lights are the only difference. I have a double speed flash on the left side that I havn't been able to fix - although I've had plenty else to keep me occupied and it's never failed an MOT. The front fogs are not wired in either - not connected at the back of the lamps. Never failed MOT with that either and the bulb warning on the dash doesn't light up through lack of fogs, only on the double speed left indicator. I'd be interested to see how you get on and if all I need to do is check wiring.

I actually swapped the bulb module with another but still the problem of the double flash persisted. Anyone shed any light on what is going on here as it may help the OP as well as me?

Yes, the grille is different. I can't say it messes with the bumper though and I should know as I have replaced my grille. I'm sure I've replaced the bulb/s - trouble is it was so long ago that now you've go me thinking maybe I didn't. One thing I did notice, and it may be something to do with the bumper change is this:

some thoughts:
- the lamp module carries the designation "not compatible with LNA2245--", is that a material difference in your circumstances?
- on the X308, the front directional indicators are operated by the BCM and not the lamp control module in the trunk. Is that the case on a X300?
- the X308 and X300 *may* use different bulbs. in that case the controlling bulb monitor would expect to "see" that bulb in the circuit
- are the ground circuits good?
- the relay pictured is a generic relay. Jaguar relays generally have a internal EMP suppression diode between pins 1 and 2 to protect the driver circuit.
Anyways, the double rate flash sound is actually quite pleasant

The question about the grille was just to find out. The X308 has a great "snout" but the X300/R has that wonderful supercharged inline 6 sitting in the engine bay.
some thoughts:
- the lamp module carries the designation "not compatible with LNA2245--", is that a material difference in your circumstances?
Just checked the parts website, LNA2245 is up to VIN 739426 and LXF2245 is from VIN 739427 so that's ok with my car.
- on the X308, the front directional indicators are operated by the BCM and not the lamp control module in the trunk. Is that the case on a X300?
I believe the x300 is also controlled by Body Processing Module which is behind the glove box on a UK RHD car.
- the X308 and X300 *may* use different bulbs. in that case the controlling bulb monitor would expect to "see" that bulb in the circuit
I know the x300 has 2 bulbs in the front bumper indicator while the x308 has only 1 bulb. So in my car, the x308 indicator has only 1 bulb, it now has the x308 bulb holder where the x300 (twin bulb) unit has been cut off. I'd have expected this mod to produce double speed flash on both sides though.
- are the ground circuits good?
Absolutely no idea on this one. This is one of those jobs where I have the luxury of gaining plenty of advice on this double flash issue from those more experienced than me. There are usually more pressing jobs to be done I'm afraid.

Edit: Plums, I've replied to your questions within your quotation - I can't work these forums properly.

@straightdohc6
The double to single bulb may be of great significance.
If the original circuit was 2 bulbs in parallel, the expected resistance is half of a single bulb. If a series circuit was used, then double that of a single bulb.
Running a different bulb type also introduces a change.
A corroded ground circuit will also introduce a change.
The reason that only one side is double flashing is that the good side still remains within system tolerance.
Your best bet is to measure the resistance of each circuit. The difference will tell you which direction you need to favour.

Long time no see..
Yess the bumper fits like a glove Have it on my X300 aswell.
As for problems with this you have.
Brake cooling ducts dosn´t fit but i dont care with this one because it´s no racer anyway..
Foglights are no problem at all to hook up. Mine works just fine
Double flash is a thing that i have aswell and no question this is because of the 308 bumpers use one 21w bulb in the indicators instead of one (there´s three wires going all the way out to the bulb 2+ and one -) will look into this very soon.
The solutions i have been thinking of is either connect a bulb that will be just hanging loose insde of the bumper or try to connetct both + wires to the same bulb.
Will let you know how it goes

I'd introduce a load resistor to each side to bring up the load required - it's a similar problem when converting the bulbs to LED versions on the 308, they fast flash unless a load resistor is fitted also.

And as for LED on 308 i have them in the rear turnsignals but it doen´s fast flash on the outside only in the instrument cluster

The fast flash rate is actually quite pleasant. Too bad the fast flash does not also carry over to the light itself because it would be more effective as a signal.
A load resistor is not the only way to get rid of fast flash. The fast flash was lost when I interposed a relay in the circuit at the rear. Apparently the coils draw enough current to mimic a bulb. The difference is that the relays don't get hot like the load resistors.
At the front, maybe the x300 used a dual filament bulb. One for what North Americans call parking lights and one for turn signals. Maybe you can find a suitable bulb holder to use with the housing that can accept a dual filament bulb.
ps. The system at the rear now works like this:
Code:
running: side markers + tail + fog flashing: side marker + turn signal + reverse reverse: turn signal + reverse reverse/turn: side marker + turn signal + reverse (on flashing side) hazard: side markers + turn signal + reverse

Perhaps your fast flash is caused by the rear led.

My XJR fast flashes in the instrument cluster because of the reaer LED. But it doesn´t fast flash on the outside.
My XJ6 that i fitted with XJ8 bumper fastflashes both in the cluster and on the outside. ANd has no LED´s fitted. All signals are working. The reason for this is that X300 has a total of ¤ 21w bulbs in the front for the turnsignal and X308 has only 2. Maybe it would be good enough drawing 5w to stop it from fastflashing and yes then it would work with a dual fillament bulb. But still if it doesnt work the connect both the positive wires together the absolute esiest way to sort his is to mount a separet 21W bulb just sitting somwhere inside of the bumper
