Audi 80 B4 Specifications

Author:

B4 Audi 80

The Audi 80 model B4 was built from 1991 until 1996 as a move by the company to compete in the luxury mid-sized market dominated by the likes of BMW and Mercedes. It was replaced in 1996 with the production of the new-styled Audi A4. It was designed and built with the usual superior quality from VAG German engineering, and the body was galvanized at the factory to keep it rust-free.

I'm in the Audi Club

The reason I made this page of data is that I own an Audi 80 Avant estate, which I absolutely love. It reminds me of BMW quality combined with the comfort and layout of my first car, which was a Volvo. I think that it looks great and has features of some newer looking Volvos. It doesn't look out of place parked next to a newer Audi either, and it has inspired me to look at the rest of the range. I might be tempted to buy a convertible Audi 80 as the perfect partner and second car.

I love the styling, reliability, and comfort!

So, here is all the data for sharing and reference, and my own interest as well. I hope that you find the information on this page beneficial and concise and all in one place. I will continue to add valuable figures and stats as I collate the information which I present in my own way. If you like this page, please be sure to leave a comment or a thumbs up. If there is anything you would like to see added or improved on, please let me know—all feedback is welcome!

Engine Codes

This list will help identify which engine type you have based on year of manufacture and model. This information is important if you are considering replacing key components or considering fitting a chip upgrade in the ECU or brain of the car. It is also very useful if you want to use parts from other models and need to be sure they will interface with each other correctly. However, a rule of thumb is if you are not sure, consult an expert first.

Wheel PCD Offset

PCD can be like the offside rule in football, easy to understand if you are into it and difficult to explain to those who are not. Hopefully, the picture below will help explain the data presented. If you are using the table to consult the options of changing your wheels, then be careful with your selection as it can be a real trick to get aftermarket wheels to suit your vehicle exactly without issues such as the wheels catching the arches or not being able to lock the steering fully.

If you are unsure, please consult your dealership or a wheel specialist. A link to the Audi website is at the bottom of this page.

PCD Measurement

audi-80-b4-specifications

The picture above demonstrates how to measure the PCD of a wheel for correct fitment. A small tip is if you are trying to fit a wheel that has a very slight difference in size to the hub pattern in question, then you can use what is known as wobbly bolts, which allow for a small alternation in the fitting and allow the wheels to go on.
