Hello,
I've got a Leon Cupra MK3 2015 that has been stage 1 mapped with a custom sports catback and it's currently failing it's MOT due to high CO, HC on the second fast idle test.
Currently it has two codes (removed), P001100 and P044100 which I have known about for a while now. Talking to the MOT mechanic, he said my Cat has gone after 2 years which is why it's failing the test, best option is to replace the centre pipe with a temporary cat to pass MOT. The mechanic who made my exhaust has said the cat should be fine and since it failed on a lambda sensor it's probably a leak with the exhaust or intake (reluctant to say exhaust since it's stainless steel). He's suggested to repair the evap canister and valve before paying stupid money.
I'm going to go with fixing the evap system since this seems to make more sense as it passed last year without this code but I don't want to spend the estimated 2k from the MOT mechanic. Looking to do this myself but struggling to find any information and locations on the evap as it's all for MK2s or Audi's.
Does anyone know where the evap canister is located? I've heard it's in the engine bay, but also heard it's behind the nearside wheel arch. Also a part number would be great since I cannot find anything online.
Worst part of fixing your car yourself besides rusted bolts is finding the correct part and it actually fitting because you've bought part number 112233A but instead you needed 112233B.
Any help is appreciated!
