Emissions Light Been On For 2nd Time, Please Help :( Got Some Codes

[Phil_T]

As above firstly came on & stayed on back at the end of July when I got home after a 3000 mile jouney on Modball round europe. Took it to Audi & I picked it up the same day for them to tell me it was a "sporadic" fault & could just be cleared. I said what could cause this & they said maybe it was all the diffrent types of fuel I was putting in on my trip (even thought I had superunleaded in but from different brands)

Now today it came on & stayed on again when I went home at dinner. I rung Audi to book it in but cant get me in till next Weds which I said isnt no good as I dont know if I can drive the car or not (btw car felt like it wasnt pulling as hard) so they told me to call out Audi assist. The guy came out did the scan which both screens said the below (I took pics to show audi or anyone)

btw they have cleared the fault for now told me to go for a drive down motorway for 15mins which I did & gave it a good thrashing & everything seems fine but that still doesnt stop the fact this has appeared twice so something must be up



First screen after scan



01 - Engine electronics

1 fault/notes detected

08584 P2188 008

Bank 1 fuel metering system, system too rich at idling speed

Sporadic



Then the next screen said the below which gives ideas as to what it could be

 

- Bank1, lambda control system too rich

- Injector leaking

- N80 - ACF system solenoid valve 1, act

- N80 - ACF system solenoid valve 1, elec

- Unmetered air downstream of air mass meter

- fuel in engine oil

 

The current mods I have is revo stage 1, evoms intake, forge dv, sachs clutch & autotech fuel pump but i dont have an exhaust could this be restricting it?

Any ideas as I am getting quite worried now & that its the second time. Was going to spend more money on it this month too but really need some help & ideas please guys

Anyone?

mm not on the ross tech wiki site.

take off oil cap and see if it smells of fuel, if it does suspect pump leaking (in which you prob want it sorted quickly/change oil and dont thrash it as the oil protection is compromised)
others seem to have had MAF or o2 sensor failures as well.

change to std airfliter and/or check fuel trim values in VCDS?

I took it off & it smells the same as my gf's car. I dont think it seems to be as vilant on boost since the light came on. They have cleared the code but there is obviously something wrong.

Any more ideas please people?

Anyone?

Car doesnt seem to be boosting properly, am sure the fuel pump prime when opening the door has stopped, it sometimes has a lumpy idle

Really need some suggestions as I dont seem to be getting any advice from anywhere as to what it could be
