How to Drill Holes for Rear Air Vents Modification on Audi A4L?
2 Answers
Audi A4L modification for rear air vents requires removing the original rear air vents, unscrewing the two black screws at the top and bottom, taking off the surrounding frame, and then removing the entire center console. The Audi A4L is equipped with two new green-efficient engines that feature advanced technology and provide ample power output for stable starts. The dynamic steering system in the Audi A4L can adjust the steering ratio based on driving speed and the selected Audi drive mode, working closely with the ESP system to enhance safety performance. The combination of radar sensors and LED warning lights on the rearview mirror improves the vehicle's active safety during driving.
I modified the rear air vents on my Audi A4L, and drilling was quite crucial. First, locate the position, usually at the reserved opening of the rear air conditioning duct, and measure the dimensions with a ruler. Use an appropriate drill bit—not too large to avoid going off track; I used a 4cm alloy drill bit. Remember to remove the seat trim panel first to expose the frame, then drill slowly without rushing, as going too fast can crack the plastic. After finishing, check for any debris that might have fallen into the duct and clean it thoroughly before installing the vents. The whole process requires attention to detail, using protective tools and wearing gloves to prevent slipping and injuring your hands. After the modification, the ventilation improved significantly, making the rear seats much more comfortable for the whole family. But be careful not to rush and drill in the wrong spot, or you’ll have to redo the work and repair the car.
