    i wonder how long it will be until the regulations state that the emissions and mpg figures need to reflect the worst 'program'.

    and how are the pops and bangs created? any downsides to the engine/cat? I assume its allowing fuel through to the exhaust..

    and an old man's perspective: its all a bit juvenile anyway and frankly from what I can see most people do not have anything nice to say about people driving around popping and banging..

    Only throttle response changes for the engine

    Indeed I have. Makes a difference, but only maybe 20% more. My old pre-GPF 290 was louder without res-delete and my friends pre-GPF 300 with no res-delete is louder still!

    Agree with this, res delete makes a difference but by no means a huge one.

    After further tests today, yes, it does stop, and immediately starts again if you change modes and back again.

    That’s 3 of us now then.

    I find if I’m in cupra mode, and the pops and crackles stop, I just select cupra again and they start again, so don’t even need to change the mode to something different!

    My 2018 Curpa R is a manual.
    If I inadvertently hit the rev limiter and trying really hard it pops and farts [PAAAAAARP} ONLY TWICE though.
    Then not again. If I accidently get near the rev limiter again it just hicuups a little and holds back like a Diesel. will not over rev.

    If I wait for about 15 minutes or forget it or restart or change modes and back again to CUPRA mode or Cupra mode in individual. Same again two PAAARPS if I hit the rev limiter then gone.

    SO yes it does seem to happen even on a manual.

    To get pops and bang are you in manual DSG or do you get them in auto ?

    Also does red delete effect MOT or anything ?

    I presume it would void warranty ?

    Guess it’s the newer models then....

    I have a 2016, manual, 290 with res delete and won’t stop popping and very loudly too. Seems very annoying to have this “problem” as I love the crackles :scary:

    From what I have heard it doesn’t affect MOT, warranty I don’t think( correct if wrong) the exhaust is covered by warranty anyway.

    So who’s going to be the one to ring Seat and ask them what’s the deal?! The dealers won’t have an answer, Seat CS won’t have a scooby and will revert to brand support (who also won’t have the faintest scooby) leaving us with silent cars. They’ll blame an exhaust mod as the reason, which is cr@p because it does it with/without res deletes.

    You've done it now - next year.
    Exhaust popping is usually air being injected into the exhaust on overrun as an emissions measure
    Banging and farting on upshifts is due to ignition retard to ease trans loadings. It allows a small amount of unburnt fuel to be ignited by the hot exhaust. Anti lag systems are different again. My understanding is that fuel is injected into the exhaust to keep the turbo spooled up.
    I'm old too, and it is juvenile, and I like it. It's like farting in church.

    I'm not that old (early 30s) and I agree with this, if you are entering a highway, or in a nice country open road, by all means, but where I live in a built up residential area, this is annoying, 1 to 2nd gear 'farting/popping.' Sometimes I hear dual popping, guess there might be 2 cars with VAG 2.0TSI engines following each other quickly I'm guessing Golf Rs and S3 and the like. Sometimes I hear 'nicer' more growly engine sounds without the farting on upshift, I'm guessing these are the V8s of powerful cars. Maybe the new GPF cars only lets you have 5 min of fun, before being civilised again :).

    so the MY68/19 290s with GPFs are basically stealth machines without the res delete and carrying out the res delete enhances the sound level overall slightly including the pops and bangs

    i
    I had the pops and bangs without the res delete on the new 290. Res delete just enhances sound, doesnt give any more pops i dont think. i dont need to keep pressing cupra every 5 minutes. once cupra or sport is selected it will pop and bang all day until i switch off

    My copra does it in sport or cupra on downchanges between 2.5k-3k, just under 3k is the sweet spot. As others have said does it all day long unless I turn off and restart the engine.

    I agree that locally the MASSIVE cracks and explosions from some Focus RS guys are intrusive. The woofles from a C63 or M3 are pleasant.

    Waiting at the gate on a Breakfast Club Sunday at Haynes Motor Museum in Somerset you need ear defenders. [1200 cars last time in June]

    However as mentioned mine stops are a few minutes no GPF fitted as it is October 18 plate R
