    Waiting room.

    My family brought their cars here for years to get our cars smog checked. I am now doing the same with my vehicle. Not only can you get your car smog checked in a reasonable amount of time, they can also process your vehicle registration for you for a nominal fee. If you process the registration when you get your smog check, they will also send in the registration on your behalf. The value of this process is worth is for me! They have a clean, air conditioned waiting room, knowledgeable staff, plenty of comfortable seating while you wait, and quick service. They are also open Saturdays as of September 2023, which is helpful for most who work during the week.

    No very crowded in late afternoon.

    Ask the Community - West Valley Smog

    Can West Valley Smog help me renew my car registration if I currently have a PNO on it? (i can't seem to do it via DMV online)

    Yes, just bring in a registration or renewal notice and we’ll take it from there. Shouldn’t be a problem... a smog check is usually part of bringing a vehicle off of PNO and reinstating the registration to current status. Just come by and we’ll be… Read more

    I got a Smog check at this place. The service was super fast and the attendant, his name was Kevin,…read morehe was incredibly friendly. Overall an amazing experience

    Antagonistic owner alluding that customers are the reason he wants to leave California!? Huh?!…read moreAnyway, I arrived at the smog station to smog my BMW 335i 2007. I presented an OBD2 app that showed all emissions tests Passed. He said that since all these tests Passed for my 2007 BMW 335i, it will therefore pass his smog testing. He simply said it would pass without any further conditions. He explained that Permanent fail codes on model 2010 and newer cars would make the car FAIL but that mine is a 2007 model car and did not have that permanent failure code. I then turned on my car and looked and I had a yellow check engine light (I think it's called), along with many other lights that turn ON and then go OFF. I asked him about that Check Engine light that was momentarily ON and he said my car won't pass now... and that I didn't tell him I had that check engine light. And while we were talking the light turned off within 10 seconds or so after start like other lights. I then asked him for clarification compared to what he told me a moment ago that it will definitely pass if there are no permanent codes but he seemingly changed his story saying it will fail because he already 'hooked it up" or something (?) in the 2 minutes. I saw no cable but I'm not sure. He began to get very aggressive cutting me off in mid-sentence as I'm trying to calmly discuss the details of how these things. I maybe get three or four words in my non-confrontational way and he's cutting me off correcting me telling me how to things are while being very rude. I had a very bad feeling immediately in 2 secs into his rant that this guy is an A$$. I gave him an opportunity to back off and he would not stop the verbal assault on me. I told him to stop with the noise saying "you win, just stop talking" But he wouldn't stop. And the only way I could get away from him coming down on me so hard was very or of my car & walk out of the shop telling him don't talk to me. Of course he wasn't done. He starts talking about California and how he needs to get out of California I'm the reason why he wants to leave California. He's not a good man. This kind of person is always worth avoiding because he wants you to be on the losing end of any discussion when dealing with him.
