SOURCE: audi a3 1.8t dump valve fitting

A dump valve replaces the recirc valve. Did you see the reply to your prior post on this topic that I put up the other day? You can do it but it'll cost you your catalytic converter and O2 sensors - that has been proven out many times in the past. If you don't care about that and don't mind spending $1200-1500 every year or 18 months to replace those parts, then go to www.audiworld.com or www.audidiy.com and look in the tech areas - there are step by step procedures there that walk you through recirc valve replacment. They'll show you how to fit an aftermarket recirc valve, but you can follow that procedure to do a BOV as well.

Seriously though, as I said before, some cars are fine with BOVs but Audis are not. You're going to cost yourself a LOT of money just for the sneeze sound and slightly slower turbo spool. Your car and money though so it's your decision.

My a3 says safe when I turn it on and won't start.


Hello,
Just a simple hint. Just try reset ECU that will fix the problem if its a minor related to electronic.
Still wont start means you need to go to shop to get curbed .
Thanks

Indercators keep sticking on Audi A3 1999?


Most probably the flasher unit. it is incorporated within the hazzard switch. they are known to be problematic on that model. sometimes just playing about with the hazard switch works other wise replace it.

Hazard light and interior lights problem on 2001 A3


the indicator lights flashing constantly might be a warning from the car that all the doors have not been closed properly

after writing this ^^ i think that the system that tells the car if the door is open or closed it damaged or broken
and needs replacing

try leaving all the doors open and lock the car do the indicator lights flash contantly?

you need to get a dianostics done but due to the reson that it is intermmitant the problem will not exist when you get to the garage

check all the sensors that tell the car if the door is open firstly

Indicator Problem


when you noticed the indicator being on solid, but flashing with the hazards, are you inside your car? I mean have you gotten out of your car to check if the bulbs are working when the indicator thrown and when the hazards are on. A hard on indicator usually means that you have a bulb burnt out. The hazards will still flash as normal when inside the car even if a bulb is burnt out because the hazards do not run via the Electronic Flasher Module. The EFM is what detects a burnt out bulb
