I have come to OC Tuning Auto for all my car needs. Oscar and his team are extremely professional, thorough and great people to work with. They always fit me in and the prices are VERY reasonable. HIGHLY recommended. These guys are awesome!!!

Best automotive shop I have ever been to. Got my vehicle repaired at a fair price and their service is great. Will be bringing all my cars here from now on

The team at OC Tuning were SPECTACULAR! I have a 2012 Audi A7 with 100,000 miles on it. Check engine light came on so went to dealer who basically told me that car should be scrapped and would need over $15,000 to fix it. Through a good friend I found out about OC Tuning. Got the car to them and they did a full diagnosis. Yes I did need new fuel injectors and a couple of other items, but nowhere near what the dealer was asking for their repairs. When I got the car back it ran as if it was BRAND NEW! Really nice crew, very responsive to questions, and most importantly, they clearly know how to service German cars at a very fair price. Thrilled with Raz and the team at OC Tuning. Theyve got my business from now on because they are honest, extremely capable, and very responsive. Thanks OC Tuning! You saved me having to buy a new car :-).

I did not personally use OC tunings service but the previous owner of my car did have some modifications done at the shop.Raz from OC tuning gave me great insight and advice about the modifications over email in very prompt times even though I was experiencing no issues. Great shop, highly recommend.

Words cannot explain how amazing this shop is. I brought in my 2020 Audi S3 for suspension noise and some basic maintenance upgrades. Raz, Dave and Nick tailored the car to accommodate how i wanted it to drive, within a couple of hours I was able to drive away with a better feeling, smooth and faster car. OC and AU Tuning are beyond amazing and Everything from Performance to Maintenance, is literally their specialty. Thanks Guys, see you in 5,000 miles

Best shop out there. Highly recommendd.

Their queue time was a little long to get in but there customer service was outstanding. The queue made sense.

Great owners and staff. Although I drove 120 miles round-trip, I will continue to have my Golf 2.5 serviced or repairs at OC Tuning. Confidence and trust in a business is important to me. Thank you again for accomodating me due to a parts issue with vendor. Nick did a great job as well. Stay safe and healthy.

Awesome! One-time. Successful!

Great service, much faster than the dealership on helping me with my car. Told me to just show up as soon and helped me right away

Fantastic Shop and great pricing! Customer service is some of the best Ive ever experienced. Came in got my oil changed and they diagnosed a faulty DRL, sourced the part locally and got me fixed up the same day. If you own a euro car this is your place. Ill definitely be coming here from now on.

I would highly recommend this shop to anyone with a VW or Audi that doesnt have the tools or time to provide their own services. Especially for any special services that you dont want to take a risk on yourself. I have been coming to Raz for work on my 2007 GTI from before the Huntington Beach AUT shop location (over 5 years). Hes gotten me out of plenty pickles I put myself in due to my lack of mechanical knowledge. I havent even mentioned that his pricing is beyond fair. Stop looking for a VW shop and call Raz NOW!

Helped me tremendously with my car, worked with me day by day on fixing everything and I couldn’t be happier to recommend them

There is a good reason OC Tuning has a perfect 5-Star rating. They know how to diagnose and fix cars. My 2003 VR6 GTI has seen three other independent shops plus the local VW Dealer because no one could figure out what was causing an intermittent exhaust odor. Thousands of dollars were spent, plus a lot of time and drama. Thankfully I found OC Tuning on Yelp and after reading the reviews decided to give them a try. In the course of fixing an oil leak they checked and cleaned the clogged air filter and no more exhaust odor. What a relief! I will trust Raz and Nick with all of my future repairs. Thank you guys - GREAT JOB! Another happy customer here.

Disgusted a fantastic job and I live in Apple Valley Dave thank you and your staff

We own 2 high performance Audis and Raz and his guys are simply awesome and chill and highly knowledgeable... they dont overcharge and they take their time in doing things right the first time... true professionals that stand behind their work... we love OC Tuning!!

This place is a true gem. Ive been taking my MK6 GTI to AU Tuning and OC Tuning since I first owned it almost 5 years ago and would never go anywhere else. Raz and crew know VW and Audi vehicles inside and out. There are no gimmicks or selling of extra services. The staff are very knowledgeable car enthusiasts and take care of your car like its their own.Ive had small jobs like brakes and oil changes to large jobs like a turbo replacement, coilover install, carbon cleaning, and timing chain tensioner replacement done here and have never left less than happy. All of their work is top notch and they take the time to explain what they are doing and why. To sum it up, great honest work done by awesome people.

Will be back thank you very much...

Simply the best shop in Orange County. Raz and Nick are great: friendly, helpful, and knowledgeable. I’ve been here a few times, and they have made me a long-term customer. The best part about this shop is that they are so trustworthy. They want the best for you and your car, even if that means charging you less. They take the time to explain things and go above and beyond in their helpfulness.

I was interested in getting an ECU upgrade/tune for my car. After researching online, I came across OC tuning. They had great reviews so I sent a message request through yelp for more information about the service. They promptly responded with all the information I needed. I called that same day and made an appointment for the next day. When I arrived, I was greeted quickly and politely. While getting the service paperwork started, the technician answered all my questions and was extremely knowledgeable. (Even about my specific model of vehicle)They even went above and beyond by inspecting my vehicle and making sure all hardware was up to specification.The service took less than an hour and I was back in my vehicle with outstanding results and power increase from the tune.These guys will definitely be my go to.

I had the distinct pleasure of chatting with and working with the owner Raz. My first impression from our initial phone call was incredible. Raz took the time to educate me on my car and the things to look out for when I was initially purchasing it. I ultimately came back to him to do some performance upgrades on my car and Raz was phenomenal in his service, his integrity, and attention to detail. He spent so much time ensuring that everything was perfectly set and I could truly tell how passionate he was about everything he did. Would recommend anyone to work with his company as they do incredible work.

Best place in OC for any kind of car repair. Super knowledgeable staff and friendly service. Great service and pricing from an oil change to major service. Just great!

I had a fantastic experience working with Raz at OC Tuning. Super genuine guy and spent a ton of time asking questions about my GTIs potential tunes before purchasing them with him.Brought my wifes Golf as well and he hooked it up nicely with quality work and very good pricing.

Excellent repair shop Highly recommended.Ive used this shop for several repairs and its saved me hundreds of dollars verses the dealership. Raz and Nick are great to work with and will explain the problems in simple terms and provide recommendations based on what should be done and what can wait.Theres also several vehicle rental options in the area that make it rather convenient.

My experience here was nothing short of amazing. Raz took the time to answer any questions I had about my car’s maintenance and future build ideas. He is very knowledgeable and was kind to use layman’s terms whenever it was needed. I had read great reviews about AU Tuning and was happy to find out they had another location closer to me, and I had to take the opportunity. Service was quick and efficient. Raz made sure he answered any questions I had before I left. Thank you, Raz and Nick. I would be happy to come back for my next maintenance need.

OC Tuning is hidden in the back for a good reason. They provide professional performance services at competitive prices. This shop is an APR Dealer and their lead technician came from AU Tuning in Huntington Beach. The staff is very friendly and helpful. They have an in-depth knowledge of the automotive industry and have worked on countless cars. Setting up an appointment was really easy and they get the job done quick without sacrificing quality. OC tuning is easily a 5 star location and they have earned my business. I will be coming back for more modifications to my car. If you are in Orange County, this is the shop you are looking for.

Raz and Nick SRE great!

Just got engine tune for my car here. The staff are friendly and knowledgeable. They would recommend things you can do based on your car and your needs but they do not try to sell you stuff really hard either. The prices are pretty good. It doesnt seem pretty busy. I just walked in on a Saturday afternoon and got the tune done.

I went in today to get my Golf R mk6 worked on. I had the cam flower and oil change done perfectly like always for a good deal. I support the shop because they are very honest, skilled and very trustworthy. Thank you for all the great work I really appreciate it..

This is hands down the best shop in Orange County when it comes to German vehicles. The staff took the time to look over my car and spend an hour explaining things to me with much patience for all the questions I had. I trust this shop with my car, they are extremely honest and the customer service is amazing.

Raz is absolutely amazing! Audi S6 C7 oil change, full inspection, and diagnostic performed. Raz is courteous, professional, and a pleasure to work with. He also take pride in his work. From my few visits, its apparent that he values relationships first. The service OC Tuning provides is world class! OC Tuning is my GO-To shop for any issues or concerns I may have regarding my Audi S6.

Excellent customer service!We had a service done on our Jetta at OC Tuning and they did great work! 👍👍

Fair, knowledgeable and friendly. Good quality of work and doesn’t overcharge.

My go-to for any and all maintenance for my Audi. Prices are extremely reasonable, the work is high quality, and the customer service is fantastic. I recently had an emergency issue with my car and with one phone call, Raz fit me in one hour later to take care of the problem.You just call and make an appointment, and youre good to go. Also, if the work on your car is going to take some time, the Irvine Spectrum is a 5-minute Uber ride away.Highly recommend.

These guy are legit! They just know their stuff!

Always above and beyond

So happy to have found OC Tuning!I had recently visited a different mechanic who quoted repairs for new calipers, rotors and brakes for the grinding sound coming from my tire. The quote seemed outrageous to me given my car only has 57,000 miles on it, so I checked around on Yelp to get a second opinion. I messaged with James who was very patient with all of my questions and emails - being a girl we tend to not have the most fair experiences when it comes to car-anything, so I had a ton of questions which he responded so quickly and also questioned the repairs I was told I needed. I arrived to a very nice and clean, air conditioned office where Raz assisted me. He inspected my car and came into the office to tell me that all I needed was new brakes, nothing else. Raz took the time to show me my rotors, my old brake pads, and asured me I wouldn’t need to replace my calipers like I was told. Raz immediately replaced my brake pads and I was out the door. I am so happy I got a second opinion here, you guys saved me hundreds of dollars and restored my faith that there is an honest mechanic business out there. Wonderful customer service and such nice guys. Shouting from the roof tops - Thank you so much!

Raz and the team at OC Tuning take care of you like family.

Good place to tune your car！friendly staff

Very knowledgeable, very friendly, and very helpful.
