    How often to clean throttle body and fuel injector

    Guest-only advertisement. Register or Log In now!
    I have a 2008 A4 and brought my car in for 15K miles service. The service technician says that to clean fuel injectors ($119) and clean throttle body (129.95) is recommended. He says that that should be done every year. How often should you have the fuel injectors and throttle body cleaned/maintained?

    Hmm, I would think if you use quality fuel you won't need a fuel injector cleaner.

    Re: How often to clean throttle body and fuel injector

    I bought my car at 48k so I did a flush myself just because.. I would recommend doing a fuel flush at your 60k service or atleast use some fuel system cleaner every once in a while because your injectors can get some carbon build up and spray pattern will be off. But as far as I know Audi doesnt have a specific time interval to do this service.

    Subscribed.

    I've dumped a bottle of chevron techron (?sp) injector cleaner on my other fuel injected vehicles' gas tanks just about every 1.500 mi.

    I'm curious how the FSI engine would differ from others in this regard, I've been considering using injector cleaner as well, but have not decided on it yet. Anyone?

    Re: How often to clean throttle body and fuel injector

    I bought my car at the collection, but I service it at Champion or prestige imports (when I had warranty). Never had an issue and they are extremely helpful there.

    I had my car for 3 years now and I had cleaned the fuel system twice already and replaced the fuel filter once. Next time I'm buying S3 injector.

    As for the throttle body I have only done it once.

    Actually this was at Prestige Imports. They gave me a Service Menu flyer that recommends cleaning fuel injectors and throttle body / induction chamber cleaning every 12 months. Because those services are expensive, I was just wondering if those services are really need that often.

    They are both from the B6, but the procedures are 90%+ identical.

    Hi guys!

    I'd like to resurrect this thread... I have a 2011 A4 2.0T, and like the OP brought it in for 15K service. The dealer (I have the vehicle serviced at the dealership) suggested a fuel injector cleaning (pressurized). I declined it, thinking it was a scam...

    I didn't see a definitive answer in this thread... Is this something I should have done, perhaps at my next service? Vehicle is running/idling fine. This is my first Audi, and the service manager gave me the hard sell.

    Thanks!
