164LS electric nuisance issues, certain buttons don't work
For the several years I have had the car, I have not been able to figure out the following issues.
I have spent more time on them then I care to admit.
1) Electric Fuel door release, never worked
2) Electric trunk release, never worked
3) Hazard warning flashers, never worked
4) The 2 green LCD displays on the climate control are so DIM I've barely ever been able to read them.
Here is where it gets weird. I replaced the entire center console unit, that giant unit with climate control and the 2 rows of buttons, including the above mentioned buttons. I have the exact 4 issues listed above with either of the consoles I have, the used one I bought from Europe, and the one that came in the car. Same. I also replaced those little green LCD light bulbs with new ones from Audi, SAME PROBLEM! Too dim to see anything. That's with the new bulbs in BOTH consoles...
The Hazards, fuel door, trunk release all seem to have in common one thing: They are designed to work regardless of whether the engine is running or if the key is in the ignition or not, Am I right? That's an interesting similarity.
They are all next to each other (the buttons that is) on the top row of buttons in the center console ABOVE the green LCD climate screens.
That top row left to right is Fuel door, trunk, blank, hazard, Front fog, rear fog, Parking lights.
Its not the whole row that doesn't work. Front fog works! Rear fog doesn't (probably the bulb as the dashboard light comes on for it), parking lights work off that button.
I can't figure this out. I thought it was the console or the buttons, replaced the console, same issue. It's got to be something not wired correctly, loose wire, bad connection, short, etc.
I give up.
