Howdie all,


my 166 has now done over 211k miles, and I am hoping to keep it running for another 10 years :)

As the time passes, new problems appear - now my trip computer has stopped working. Meaning that I cannot get it on screen anymore pressing the Trip button. The Clima button is also not responding. All else work as expected.

When this started happening I could still bring the Trip computer up by holding the button for long time - up to a minute. Now it has stopped responding altogether.

Have tried disconnecting/reconnecting the battery, taking the buttons out and using contact cleaner, pressing all the combination of keys I could think of.

Any advice - what shall i do ? Can I get the buttons from another 166 and replace them ? Or do I need to replace the whole screen as well ?

Another thing I have noticed is that screen is quite hot to touch, but I do not know whether that is a new thing or whether it was always thus.

Any help appreciated ..

Thanks,
Peter

Mine gets warm to the touch, probably exacerbated in recent weather, but not so hot that you'd burn your fingers on it.

Probably easier to replace the Ics altogether with a known working one from a car being broken. You'll need to make sure you get the code with the replacement one. For ones from early cars, you can calculate the code if you don't have it. For later ones (I think mid 2001 on) you'd need to have the code, or, if you knew the reg number of the car it came from, you can pay a dealer £20 to get the code for you.

Your existing Ics probably has broken solder joints or similar, or the microswitches need removing and new ones soldered in place. You could probably take it to an olde worldy TV / electrical repair shop, tell them the buttons don't work, and they would probably happily charge you to identify the fault and do a bit of soldering for you.

I think the key differentiator is the model number.
The 2569 code can be worked out the 2580 needs to be bought and paid for so to speak.

I did precisely this after buying my car in July 2016 and only then discovering that Clima and Trip buttons didn't work (also Phone but I don't have one). Found a Sony-specialist electronics repair place - funnily enough located in my neighbourhood - they pulled out the ICS, charged me 50 leva (around 23 quid in today's money), and they've been - touch all available wood - working ever since. I would certainly explore that route before going to all the hassle of a replacement unit, which could well have its own set of issues.

I swapped the units in my 3 litre and the passenger side speakers starting working again.
BUT the sat nav wanted a code (not the regular ICS code) which meant I had to disconnect and remove it.
So Frank has a point!
