AUDI has boosted equipment levels on its A3 range and extended an upgrade programme for the A4.

In the A3, a CD player is standard, while SE models upgrade to 17-inch alloy wheels and Sport models get a new design of wheel.

Inside, S line models now come with full leather trim as standard. In the A4, buyers can benefit from a free upgrade to SE specification until March 31. Upgrading to S line trim is also available at a reduced price of £750.
