recently ive been drivin my vrs and around 3500rpm up to 5000rpm it feels like its not pullin anymore?? ive been told it could be the air flow meter?

but i had it put onto a VAG computer and came out with this...

P0411

16795

Secondary Air Injection System

Incorrect Flow

Anyone had this problem before? and what is it??

Any info wuld b great...

Here should help 16795/P0411/001041 - Ross-Tech Wiki

I would look at the secondary air pump as the rivets have a habit of corroding. They can be drilled out and replaced with bolts if thats the case.

How did you get on? I have the eml light on with the P0411 code showing, I had it reset during service about two weeks back but came back on yesterday. Cars running fine as far as I know, sounds quite diesely when started and the secondary air pump is on.

Could my P0411 code be caused by the secondary air pump as the light came on after short hard accelerating roughly 5 minutes after starting the car? I would think the pump is off by then.

Until the coolant and catalytic converter are hot enough the ECU can switch it on. 5 minutes of running at this time of year will often not put enough heat into the Cat and if you booted it could have caused it to come on hence the fault code.
