Because it would have been difficult to refurbish the sun visors (especially with the paint damage), I simply replaced them with ones that I found at the junkyard. As an added bonus, the sun visors I picked up didn’t have those unsightly warning labels on them. This post will go through the removal of the sun visors so that you know how to safely remove/install them, whether you plan on replacing them or taking them off to do a proper cleaning.

Replacing the cabin air filter on any vehicle is usually pretty easy to do. The location where you replace the cabin filter tends to either be behind the glove box, or near the firewall in the engine bay. The MKI Audi TT’s cabin air filter is located in the engine bay on the passenger’s side. There is a small flap that needs to be opened in order to access the cabin air filter for replacement. It is typically recommended to replace the cabin air filter approximately every 10k miles.

As I work through the issues on my new-to-me 2002 Audi TT, I discover more and more things that need to be fixed. While I was fixing the secondary air pump in the engine bay, I happened to come across a set of hoses in front of the engine that were broken. These hoses are part of the N249 system, which is related to emissions. Because of the age of the vehicle and the exposure to heat from the engine, the piping on the N249 system tends to break, which can cause a vacuum leak in the emissions system.

This short cable that is broken off in the photo below is a battery ground cable. This cable should be connected between the negative terminal of the car battery and the body of the vehicle. Over time, if the battery is not securely tied down, the wire strands of the battery ground cable can fatigue and break due to constant movement. Rust and corrosion will accelerate this process. This can potentially be a safety issue and you might see some voltage issues as well.
