Avoid the long lines at DEQ and come to Marque Motors!

DEQToo Service

No Appointment Needed
We provide the DEQToo service during our regular business hours.

Does your car need a DEQ emissions check? We can help!

Marque Motors is an authorized Business Participant in the DEQToo Program. We can transmit your vehicle's on-board diagnostics data to DEQ. We charge a Device-Usage fee of $10.00. If the car does not pass DEQ's service determination, we will not charge you the device-usage fee. Note that none of this fee goes to DEQ, they do not require a device-usage fee and they do not set the amount.

After the data gets transmitted from Marque Motors, DEQ then immediately displays its pass/fail determination at for you to view by clicking on "Check Results" and entering your license plate or VIN. Once you've passed and paid DEQ online, you can then renew your registration online with DMV. Your stickers will arrive in the mail within as few as 3 business days.

Note that to use this program everything must be done online; not at DMV or DEQ. When you renew using DMV's online registration system, you'll need your DMV Renewal Access Code which can be found on your DMV renewal application.

PLEASE NOTE: 2005 vehicles and newer. Cannot be 75 days past expiration date.
Call for more details: 503-293-5386 or go to for more information about the program.

What Our Customers Are Saying


You Guys Kick arse!! Thank for the work you do!! The power from 3K to 5K has improved and it has a quicker response. Great upgrade for the money!! Thaank you!!


Marque Motors was recommended to me by several of my 'German Sport car owning' friends. Kurt was very generous with his time to help me understand the differences of the cars that I am researching to purchase (Porsche vs. Audi). He gave me some excellent pointers that I would not have thought about before pursuing a purchase. I will definitely bring the car to Marque for a full pre-purchase inspection when I identify it, and any service and repairs as well. I believe they are an excellent resource!


I've taken a number of Porsches to Kurt over the past 15 years or so. They do careful work, give great advice, and have been very reasonably priced.


I was recommended Marque Motors for a pre-purchase inspection on a Porsche Boxster in Portland. I don't live in the area and hadn't actually seen the car myself, so the inspection was really important to me. Kurt was great and gave me all the information I needed to make an informed purchase, taking time to explain the report details over the phone and answering any questions I had. The inspection also cost me less than I was originally quoted which was nice! If I was anywhere near the area, I'd definitely be going back to Marque Motors for any work my car might need in the future.


We have been doing business with Marque Motors for a long time, this is a quality shop. All my customers that drive Porsches, BMWs, and Audis take their cars here and have nothing but GREAT things to say about their work. Kurt has a very good reputation and his staff knows what they are doing. Marque Motors is a full-service repair facility specializing in Porsche, Audi, BMW, MINI and Volkswagen. NOTE: SERVICE & REPAIR FACILITY SPECIALIST ! Service and Repair Shops that have been around a while are getting harder to find, this is one of the good ones. We are in the industry and my customers say this is a great shop, and I agree.


Kurt and crew always have done what they say, when and for the amount agreed to. They serviced our 1999 Audi A4 for the last 13 years, and I would use them again, and recommend them highly.
