Hello!!

The LCD screen on the cluster of my car has a lot of dead pixels (can't read a thing) and I want to replace it. I took the car to the local Audi dealership and they say they can replace, however it is really expensive (around $600 USD) including the spare LCD replacement, they can also replace it if I give them the screen (with a lot of paperwork due to warranty and the part not being authenticated by them etc.)

I found a lot of replacement screens on ebay and amazon. However I know there are different models of screens, is there a way for me to identify the model of the screen (without putting the cluster apart) my car use?
The screens are relatively un-expensive ($20 USD regardless of the model) so I was planning to buy all 3 models and take them to the dealership for them to do the replacement and charge me only for the replacement work.

Any assistance will be appreciated.
