As houm said, first you stop the water; of course easier said than done.

Re drying, lift up as much carpet as you can so it is exposed both sides and then put a household fan inside to blow air onto the wet area. Maybe a week or so, and the carpet will have dried out. That does not mean the wires under and in the door sills will also have dried - that is another challenge.

Also review the heater / AC drain files within the link below. The two drains can self disconnect and dump all the AC water or rain water entering the heater/AC system onto the left and right sides of the tranny tunnel inside the 3 instead of draining thru the floor and onto the ground. I see the two related files have in excess of 1,200 views so the problem is not unknown - also not pretty easy to fix and costs nothing.

I'd also take a few feet of trimmer line and push it down the A/C drains to clear out any potential blocks, especially since its a 2 min thing

 

Do the original AC drains have the same silly design that the sunroof drains have? That cross-type end that clogs?

 

pretty much.

they exit near the transmission (up on the tunnel), so good chance for road grit to get stuck on it over time and clog

 

Hello,
I have the same problem with my 2007 Range rover Sport (RRS) HSE. The tire pressure lights come and go off, the parking brake light is on, and I get this message "vehicle fault, system shutting down (at times when I drive). I suspected the instrument cluster (IC) was bad (based on my reading) and a RRS dealer told me if that is the problem, a new IC needs to be made in the UK specifically for the car and the mileage. I have question, How did you get an IC and who installed it? I live in MI and I need someone around MI, IL (chicago), WI, MN that can work on the car. The dealer told me that a used part will not work for a RRS. Thanks

Hello,

I have the same problem (Tire pressure light, vehichle fault (system shutting down), parking brake lights on) that may be caused by instrument cluster. Did the new instrument cluster solve your customer's problem? I live in MI and I am looking for someone that that do the job. Any recommendations/suggestions? I went to an RRS dealer and he told me that a used part will not work for a RRS and that a new IC has to be ordered from the UK. Thanks

 

See my post #26 above. The odds are you do not need a new instrument cluster; just unplug and replug in the single big cable that feeds all - might just fix the problem as over time the plug gets loose for whatever reason.

If that is the problem, then replacing the instrument cluster would achieve the same results at the cost of a few thousand and all would be happy - even you.

Thanks Bbyer.

I will suggest that when I visit the mechanic; I do not even have a clue on how to access the cable. Thanks again.

I would not want that to be the fix - it takes real skill to re-solder a chip.
I much prefer the fix where one just unplugs and replugs that one and only connector back in. It seems on the 3's that the cable to the back of the board is perhaps a bit short and that it is pulling on the connector all the time. With temperature changes etc, the plugs works a bit loose and some of the individual connections are lost.

This usually shows as one of more of the gauges not working or worse, the vehicle just will not start and no one can figure out why as battery etc seem OK.

 

Has anyone tried Instrument Cluster repair service, as way to repair the CanBus lost communication problem? Can you share your experience?

 

I cannot figure out what you are asking. Do you have some sort of specific concern related to your 3 or is that some sort of general question?

A CanBus lost communication message "somewhere" is common, normal, routine, and probably nothing to be concerned about. If you are seeing that message I presume you have some sort of BlackBox Faultmate or similar; if so, it helps to say where or what you saw the message on.
If you have red or yellow lights showing up or gauges on the instrument cluster not working or seeming erratic, you have to be specific.

Also you might respond as to if you have tried the fix per post #39 above - an unplug and replug can resolve many problems at very little cost.
