Pulsing cluster?

[DarthVaderCayenne]

HI guys wondered if any one could help???

My 2003 Cayenne TT has an issue with its cluster. When cold and the lights are on the cluster lights pulse i.e. they glow brightly and then dimly on idle, after the car has been on for a while it sorts itself out. Recently i have notice that on starting the car it does sound very tired, like it needs a new battery or something....I dunno??????

Can any one help with this situation please????

2008 - 2003 = 5 years

Your battery was old last year. It is rare for (any) battery to last longer than 4 years. I would start with a known good battery.

Thanks for the reply i have a new 110a battery, just waiting to put it in...will keep you posted on the outcome of this change of battery

Ok update....Changed the battery on the car but the clocks are still pulsing, i have noticed that when the car warms up fully the clocks stop this annoying pulsing...Does any body have any ideas of what this is?????

Has the cluster ever been out? Any chance that a connector is loose?

[DarthVaderCayenne]

No i dont think the cluster has ever been out, confused as how a loose connector would remedy itself whern the car is fully warmed up, thanks for the input Loren, by the way how the heck do you take these clusters out as i can see no screws or anything???????

What does the voltage gauge say when all of this happening? Does your Cayenne have a second battery?

[DarthVaderCayenne]

I dont have a voltage reader on my car, dunno if the car has a second battery either???? i have managed to source another set of turbo clocks so just gonna put these in to see what happens??

You don't have a voltage gauge in the instrument cluster?? I thought all Cayennes came standard with this feature.
