Hi there new owner of an a4 convertible 2003 2.5 v6,
Got a cpl of issues

1,is the an how to guide for changing front passenger side window regulator

2,the radio fitted is wrong it's got a navigation plus which is to big to fit in the gap correctly,
Can i fit a standard radio with adaptors and radio fitting plates or am I best to find a correct one?

 

Check Youtube for a video on the window regulator. Or you can get a "Haynes" repair manual at AutoZone, Advance Auto, Pep Boys, or any other automotive retailer. It should cover things like that. Or send me the Body and Engine/Trans combination codes and I'll dig something up to scan for you.

The radios in these cars are uniquely shaped and while there are substitutes for them, they are generally quite expensive. A factory replacement that would fit perfectly can be had on eBay. I got a new factory Bose Symphony radio with the cd-changer for about $100. Took every bit of 10 minutes to swap out.

 

Hi dave it's a 2003 a4 convertible 2.5v6 diesel with auto gearbox

 

I need the number codes. There should be a big sticker in the spare tire well in the trunk with it on it. It'll have the VIN number and all the option codes for the vehicle. I just need the chassis, engine, and trans codes.
