RS4 engine light on with no performance drop

[Matt@Reflex]

Hi Guys.
I am having a little problem with my car.
Some of you may know it (this one)
http://www.rs246.com/index.php?na...wto ... highlight=

Anyway The engine light has started coming on and staying on until i clear it and then it comes back on after a while normally when i'm driving economically (if there is such a thing )
The car still goes like stink and has never dropped to limp mode.
It has Miltek DP's and pipe
Here is the Vag-com log before clearing it.
Am i right in thinking that it is running rich because of the REVO map?

Hmmm linky no workie,is it by chance my old beast?

[lengster1]

I never got that code while i had it if it is indeed my old beast,maf? maybe? What settings do you run with the sps high boost is hard on the turbos and for special occasions and good fuel only,even so never got that code when lambdas went and egt sensors

Hi ya,
Yes indeed it is your wonderfull machine.
http://www.rs246.com/index.php?name=PNp ... highlight=
I have never altered the sps. It is on 3 - 5 low boost and i have only ever ran it on optimax since day one.
Its plenty quick enough at that setting
Its puzzling me and i dont really want to buy a new MAF if its not going to fix it.
So are you saying that it should not be saying that its running rich and that i should start investigating that.

Thanks for your help.

Good to see your keeping her tip top,i would have it looked into it never came up up with that code in the 4+ years i had her so yes i think something needs looking at.Good to see you on here and the pics of it look fab

I'm being told to pressure test the intake system.
Its just weird that the performance is still there.
Its now on 75000miles so still nice and low
I need to get some nice recent photos on here even though nothing has changed
