Hi, i am new to the forum, this is my first post. I have a Seat Leon Mk2 Cupra. I have the following fault codes P0441 EVAP Emission Control System Incorrect Purge Flow (lower limit exceeded) + P2187 System Too Lean At Idle, Bank 1 (No Signal/Communication). Does anyone know what it could be, i have been advised it could be a boost leak.

Recently had a full service, Pick up pipe replaced, Rocker Cover Gasket, PCV valve plus the seal and a MAF sensor

any help would be much appreciated thanks

Hi, I had a problem recently with a vacuum leak, for me it ended up being the PVC valve (I had to replace it twice as the first replacement was faulty)

While I was looking into the problem I read about the purge regulator valve (n80) that can cause code P0441. I haven’t changed mine yet but plan on replacing it this week along with the charcoal canister.

The valve is around £20 and the canister between £30 and £40 from what I’ve seen and both seem relatively easy to fit although I haven’t had first hand experience yet.

There’s some more information here:

Hope this helps!
