Question about 1997 BMW 328
The check engine light is on and the codes the mechanic wrote down are p0441, p0442, p0455 and another one I could not make out. looking online I saw that I would probably have to do a smoke test. What can I look at before spending money on a smoke test. Where are the evap canister and selenoid & etc. located. I want to pretend I know what I am talking about if I go to a different mechanic. I think the light came on after we had the ignition switch and holder and key and stuff replaced. a little while after that I replaced the radiator then a couple of months or so later the thermostat and a hose, last week the clamp on another hose....
Honestly I think the best bet with those EVAP codes is to pay for the smoke test. It will find teeny tiny leaks in the system and will save time. If you just start replacing parts you are totally guessing.
Sorry but that's the really the best option. To help inform you before you go, check out the following resources - P0441, P0442, P0455
