    Code P2188: Bank 1; System too Rich at Idle HPFP, N80, or PCV?

    Guest-only advertisement. Register or Log In now!
    Over the past year I've had about 5 intermittent occurrences of a hard start while all other starts were normal, on a B8 2013 Audi Allroad. When this happens, the engine will crank but not fire until after ~5-10 seconds. Once it fires it will run on a cylinder down for a second or two before running normally.

    This issue disappeared for a while but has recently resurfaced. On a recent day, after driving to a store, came back out and car would not fire. I put gas pedal to floor and cranked and it immediately fired. Check engine light came on and the following DTCs were pulled. Of other note: fuel mileage was noticed to have dropped 3 mpg/hwy recently as well. There are no issues at refueling (N80 purge issue), nor does the engine ever misfire, stall, or stutter. It is only a rare issue at initial start. I sense a hint of gas smell in oil but I'm unsure if it is excessive or not. Engine oil has always stayed at full level, but has dropped a quart (@8k miles) which was unusual.

    Any opinion whether these issues, and 4106 - Bank 1; System too Rich at Idle, P2188 00 [096], point more toward N80, or PCV, or HPFP as the culprit? Any thoughts are appreciated.

    HPFP is going bad I bet. Is your oil level rising as well and stinks like fuel?

    Same thing happened to me. Changed e HPFP and after clearing the code it never came back.

    Had this code when I bought the car. Spent the $650+ to get the full rebuild kit from FCP euro and the code went away with the piece of shit fuel pump. Whomever at Audi thought it was a good idea to put the fuel pump where it could leak fuel directly into the engine was smoking something I never wanna try! Dumb, dumb, dumb.
    I just recently discovered my intake manifold runner flap hex connection has popped out the back of my IM leaving me with a Hoover of a vacuum leak just as 1000s of others.
    Now, I’m thinking it was the degradation and eventual failure of this piece that has been the cause of my shit gas mileage for the last two years. Change the HPFP, the cam follower that pumps it, change your fuel filter, check your lines, and check that runner flap arm!! It may save you 1000s of dollars
