2000 Audi A4. Consumer writes in regards to the ovd 2 unit in Audi and vw vehicles the consumer stated the problem involved the ovd 2 unit which communicated the smog test results to the computer and dmv. Although, the vehicle would pass the emissions test, there would be a communication error. The dmv required the communication and made no exception. The root of the problem stemmed from the ovd 2 unit placed into the radio. When the radio is replaced with a non Audi or vw radio the ovd 2 unit is no longer there. The consumer was informed the price to replace the radio containing the ovd 2 unit is $1000 and up.
The lcd driver information center is pixelated, this normally wouldn't normally be a huge problem but this screen informs the driver of high engine temperatures, low oil, low coolant, etc. I'm unable to read the screen and have no idea what it is attempting to tell me when my car makes a very high pitched beep to inform me there is a problem. I've also discovered that this is an extremely common problem with cars of this model year and several other model years.
