PCM Screen
RishiHanda replied to RishiHanda's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)
OK so I managed to buy a screen from Portugal in the end for 240 Euros, it arrived, i've fitted it and all is back to normal - RESULT! very happy :) -

Maple replied and want in the region of £400 to repair which is a bit steep, the guy from Japan on the eBay auction is saying he can supply a new screen for around £200 and confirms it is compatible with my PCM2.1 - I might get the screen and just fit it myself... but knowing my luck it won't be the right screen! -

lol...very funny mudman ;) Thanks Richard, i had already contacted Putnoe and they don't do them, I have contacted the other company. there seems to be someone in Japan who has them (http://cgi.ebay.co.uk/Toshiba-6-5-Display-Audi-RNSE-BENZ-comand-PCM2-1-/170410204314?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item27ad3d5c9a#ht_808wt_906) - the image is not correct on the auction but i have emailed him. i will let you all know where to get these screens from when i can find out. krist007/and others - i've attached images of what screen is doing - is yours doing the same? im at the stage now whereby tapping the side of the dash is not fixing it, and it just randomly goes back to normal colours from looking like that in the images... i have contacted some scrap merchants, if i was able to buy an entire PCM 2.1 unit - would it replace my existing one without any ECU reprogramming or similar? or is every PCM unit unique to that Cayenne? Thanks

Thanks for the replies guys, I had already seen that and watched the video - I normally spend quite a bit of time searching before asking the question to avoid duplicate questions! I can easily take the unit apart and replace the screen but still have the problem on where to get a screen from... I have found somewhere in America that wants $600 + shipping, but I'd rather buy it from the UK as it may get damaged in transit. BUT it might just be the ribbon cable - i have ordered some torx screwdrivers so as soon as they arrive I will take a closer look. hopefully it is just the ribbon cable, so maybe re-seating that may help (fingers crossed...!) -
Hi all Can anyone point me in the right direction on where i can buy a replacement PCM screen for a 2004 cayenne turbo. Mine is going a bit funny, the colours invert and if i give it a slight tap on the side its fine again - so im guessing either the ribbon cable is loose or the screen is on its way out. I live in the UK - can anyone suggest where I can buy just the screen from? Thanks

Loren, i didn't state it doesn't exist. All i'm saying is that late 2004 Turbo and onwards do not seem to have this part, but 2003 etc do. please read:
-
Loren, i took a good look and there were no wires or anything that seemed to be missing. i've replaced these switches before on my old Mercedes so i know what im looking for, my version simply does not have one... with the brake lights still working fine, it validates the brake sensor switch's operation. please see part no. 5: http://www.autoatlanta.com/porsche-parts/9PA-03-06/604-00.php But I'm not convinced its this part at fault due to the brakes and the lights working fine... thanks
-
Loren, thanks for that but as stated i've already checked and my car does not have a brake light switch. The late 2004 and onwards do not have a brake light switch as per your diagram. I believe the replacement is the brake pressure sensor which is situated under the brake master cylinder, quite an awkward position in the engine bay - however normally if that is faulty warning lights are displayed on the dashboard. I have no warning lights, my brake lights are working perfectly normally - i can start the engine without pressing the brake pedal and the cruise control does not operate. Any other ideas? Thanks
-
thanks, but as i said in the other thread i do not have a brake light switch under the dash... so i still have this problem and there is no switch to replace under the dashboard. thanks
-
Hi - sorry whos RFM? I'm new to the forum and only recently bought my Cayenne, the problem is still apparent... Can anyone help? thanks
-
Hi, hopefully someone can help me! I have a 2004 Cayenne Turbo, I have (which seems to be) a common problem in that the cruise control is not working, i can change drive mode from P to D etc. without pressing the brake pedal. On reading the forum I can see that earlier versions have a brake light switch, located above the brake pedal under the dashboard, that typically needs replacing. However, I do not have such a part, where the brake light switch should be there is nothing there and its just empty where the part would normally be housed. Therefore this would indicate either the brake light switch is maybe elsewhere or the problem is as a result of something else. Can someone please help and point me in the right direction as to possible the location of the switch or another solution to the problem? Would greatly appreciate it Thanks
