    Question S4 EGR deletion??????????????????

    I read about everyone blanking or deleting their EGR valve and a fully understand why. Both cleaning and blanking will improve throttle response etc.

    The valve is purely to lower new car emissions and after the sale of a new car serves no purpose at all. I have a very experience guy who looks after all my vehicles and he recommends removing them on every vehicle (apart from Renault Legunas as they have an odd type).

    I trust his judgement but just wanted to know if anyone has done it to the 4.2 V8 in and S4 and if there is a purpose made kit available?

    Cheers for your help in advance.

    S4's don't have EGR. They only have secondary air injection for cold start.

    Was just looking back through old threads and it jogged my memory. I have a fault code on my S4 and Ross Tech say to check the EGR valve.

    i wouldn't know anything about what the EGR valve does or where it is located other than what I have read on the link i have posted but you can apparently buy a replacement.

    s4,s do have an egr valve , if its working leave it well alone , there is no benefit to blanking it off only a load of trouble with emmision codes

    Ok thanks, I'm not really interested in blanking it off or deleting it, I just wanted to know for sure if the S4 definitely had one or not.

    Thanks
