Console Button Lights
Hi There,
A while back at work i left my sunroof open and didn't realise the rain until too late. It wasn't a massive amount of water and i dried everything off and it was reasonable if a stupid move :-( Anyway after that the red back lights in the center console have been iffy. Sometimes pressing would get them on, sometimes they'd work and now they've just given up the ghost. It's not a major hassle and i know where the CD or NAV button is by now, but occasionally they'd be useful, so am thinking of finally looking at the issue!!! Any pointers as it's a bit i've not removed on the D3 etc |
You have to buy some 99% isopropyl such as from cpc farnell and then take out the PCB and flush it to remove the water.
As far as I remember, remove the ashtray, remove some screws, remove the something else and maybe 2 more screws under that hold the centre console in then it lifts out. There are about 5 plugs to take out, remove them and then take in the house. Remove the back plastic, EPB switch and maybe start button (check this instructions in SSP as there is a trick with a sliding pin) and then wash the PCB in the sink and leave until dry about 15 mins and then put all back together. You might be able to do this without removing the PCB via the gaps, but I would worry about the isopropyl affecting the soft touch coating on the MMI buttons, it seems to go soft when damp. The isopropy is very miscible in water and not conductive so will displace the moisture in all the nooks and crannies and microswitches and will dry off quite quickly due to it's volatility. |
Have same issue , Try it to wash it , but its didn't help me..... Anyone across UK fixing MMI ? I can simply send over mine 3g high mmi panel... Thanks

Are all the lights off or just some? If all there must be a single point of failure. If just a few, may be the LEDs themselves and you could perhaps get new SMDs (surface mount diodes) of the correct size.

There is a 1A fuse for illumination, maybe worth checking....
|
So mine problem is like , MEDIA and RADIO button completely not working , So I can press Telephone and maybe it will switch Media or Radio or telephone...
So basically not working properly just 4 buttons on the left side of console , all rest is working as should How to get it fixed? PS- All LEDs is working on mine fine |
There is a company in the UK called HappyDayz Ltd that offer a repair service. Here's a link to their site, and specifically to the 3G MMI High:
https://www.hazzydayz.com/mmi-3g-bas...ate-8536-p.asp Their prices are listed as 'Supply & Fit', so I'd suggest contacting them to see if you can send them the part for repair, and what the cost would be. Depending on that, you might want to consider the other option of just buying a new one. Our forum sponsors have them for sale on eBay, or at least I believe so, as the centre control button has the small joystick on top. https://www.ebay.co.uk/itm/192954474927 |

An hours work and a day of drying time? |
Was trying to clean and dry, but fitted after 1hour dry.. Maybe just thats why its doesnt work for me :Confused::Confused:
Maybe You can give advice what kind of cleaner to use on it ? +++:Confused: |

That said, if the PCB is also contaminated, you could possibly clean with IPA but the issues are likely to be beyond cleaning if it was powered up whilst wet/sticky. |
