    Auto Union Tuning is amazing! They specialize in Porsche, Audi and VW, however I brought them my Kia Stinger and they did a great job. I originally brought in for an oil change. As part of their service they did a full inspection. They found some other things that they recommended I have done. There was no pressure whatsoever from them to get these things done. He even googled to see if some of the items were covered by my warranty and recommended I check with the dealer first before paying them to do the work. They use a really cool software that sends you pictures and a breakdown of each item with notes and costs. If you are thinking of going to them... DO IT! I will always bring them my cars. A+++

    I've been a customer of Auto Union since May 2024. My friend recommended them, and I'm so glad he did. They're incredibly attentive to my MK8 R, providing all the necessary maintenance at a better price than the dealership. They tuned my car, and it's been running like a dream ever since. I drive from Los Angeles to this place! I couldn't be happier with my car shop!

    Ive been here many times and trust me these guys know what they're talking about. From engine work to the suspension and even getting the right tune. Best shop I've been to and the only shop i go for all of my cars needs. The inside is clean and service writers are always very patient and knowledgeable. They always show love and give compliments on my car. As a paying customer i really appreciate the level of detail they put into every install. For your VAG needs come to AU Tuning. Shoutout to Nick for always being an email, call or text away!

    We found this shop by word of mouth in our community. We took my son's GTI there to have it repaired and the shop exceeded my expectations. They were professional and Nick communicated throughout the entire process. Shop was clean and you can tell they pride in their work. They were very thorough and the prices were good! We will definitely go back if we ever need any of our cars repaired!

    Remus exhaust for Golf R

    Top-notch service and communication from this place. I purchased a Golf R earlier this year and finding a specialist shop to take care of my vehicle was a priority. I went with AU tuning due to their years in this business and the work they put into VW and Audi vehicles. Starting with communication, this place communicates highly efficiently. While emailing Raz and Nick, whether for maintenance, fixing an issue, or even finding me the parts I want. Their communication skills never missed a beat. I had them complete the 30k service on my Golf R here and I really liked that they took their time to document everything, at the end I got pictures confirming all the work they did and even pictures confirming the transmission leak from previous paperwork I received. I recently got a Remus exhaust installed here and they worked with me to get the parts from their suppliers. With confidence, I can say this is my home shop for my Golf R and I wanted to thank the team over at AU Tuning for all of the work they put in.

    I told Nick I was completely new to the world of modifying cars, especially Audis, and he couldn't have been more helpful.

He is Neel the owner (as you might've guessed) of this establishment on Imperial Hwy, which is thankfully not too far from us. He diagnoses quickly, gets the job done efficiently, charges reasonably compared to other mechanics we've gone to in the area, and above all is a man of integrity--he's allowed us to pay for certain repairs days later to make sure our car is running properly first. He is transparent about his shop's limitations (they don't do German cars but refer us to highly rated shops nearby). He is clearly very experienced and knows how to weigh the best repair options, especially for older vehicles. I plan on relying on Neel for years to come. Cheers!

They were busy but insured me it would only be about two hours for an oil change, break inspection, and tire rotation. Got a call about an hour later from Neel himself saying my Rav 4 was ready to go and didn't hassle me about doing any additional work, which I feel you get every time at a mechanic shop. It was a great feeling to just get the service and feed back you requested. Thanks Neel and Hector for the honestly, professional input, and transparency. Look forward to working with your company in the future. Only downside is parking. Be patient and you'll find one.

    My car's electronic parking brake system needed to be reset because the car was showing an error…read moreafter my husband change the pads and rotors, the parking brake was working fine but the computer wouldn't reset. I went to the pos Puente Hills Mitsubishi at first for help and was told it would be $300 to disassemble the entire braking system to even have it diagnosed when all it needed was a 5min reset by specialty computer tool. Came here to Tokyo Automotive Repair to see if they could help, and Kevin upfront was so nice. The tech, Kai I believe, took care of it right away! No more error beeping. Never going to the dealership again.

I'm always on time with oil changes 5k miles no matter what year... I relied on the old reviews of this place with Tatsu but I agree, I met Kevin and he isn't that welcoming, not sure if he's going thru something in his life and taking it out on customer but I also agree, he's short, can come off as rude and idk, doesn't seem to enjoy talking to customers about cars. I asked for oil change only and got quoted over 200$? He tried to say the better oil was recommended but like dude I can go to valvoline right now for 100$ no questions asked.. I think they try to charge more because they use high tech diagnostic equipment which is great for major issues but for simple things I was displeased to get upsold when my almost new car is in great condition..... I was hoping to build a lasting relationship with this place but I'm going back to my trusted dealer who is a bit farther but worth the drive, Fitzgeralds Auto in Costa Mesa or OC Masters Tech in Orange for my MAZDA!

    Jesse is the reason my cat is alive…read more Last weekend, during the Garden Grove toxic chemical evacuation, my tuxedo cat decided that the undercarriage of my cousin's Tesla Model Y was a great hiding spot. It was not. He was wedged in there for 12 hours with no food, no water, and zero litter box access. He was absolutely losing it. I ran through every option. Fire department? Busy with the actual chemical explosion rattling all of OC, fair. Animal control? Ghosted me. My cousin, currently out of the country, tried Tesla Roadside Assistance through the app. Tesla's answer: their technicians are not trained to rescue animals. Noted, but deeply unhelpful in the moment. Two other mechanics passed too. Jesse was my third Yelp attempt and my last real option. He showed up within two hours, no fuss, and got straight to work. He tried everything - the frunk, underneath, removing the right wheel - methodically working different angles for an hour and a half because my cat had chosen the most inconvenient possible position to be chonky in. Jesse stayed patient the entire time and got him out safely. My cat is home. He is fine. He is completely unbothered, as cats are. Jesse showed up when nobody else could. That is not something I will forget. Oh, and his prices are insanely reasonable. If you need a mechanic who will actually show up and problem-solve, Jesse is your guy.

    As you can see by the other reviews, Jesse the owner needs to improve his organization and…read morecommunication to run his business better. My experience was called to book on Monday morning, quoted the price based on easy to describe work and an appointment for Wednesday at 8AM. So I adjust my schedule and am ready. No show, no answer calls or texts until a call at 930 - where he apologizes for issues on Tuesday and will show up at 5PM. Fine. I'll adjust my evening plans too. An organized person would have adjusted plans and communicated Wednesday if they had issues/delays Tuesday. Then, at 2PM calls back and says looking more like 530PM. And then he says... oh? Did I give you a price already? Oh that's actually a lot of work and says it'll actually cost 60% more. That was enough to call it quits. While I can't speak to his mechanic abilities, he fell short on: 1) being able to accurately understand and estimate work before quoting, or worse, stick to his quote when he gets busy 2) ability to plan his schedule and communicate reasonably. I hope he learns from this and other experiences and reaches his potential through better consistency.

I was hoping it just needed a Freon recharge. After checking the A/C system, Frank confirmed that the Freon was just low and everything else looked good. Luckily, her older car uses the newer, less expensive Freon. I just hung out while he recharged the system, and it was ready to go about 20 minutes later. The cost was only $150, money well spent to get ice cold air conditioning back. The most recent visit was to troubleshoot a service error code and ABS and brake warning lights. I was hoping this would just be a sensor on one of the wheels, but Frank said it looked like the main ABS ECU unit was faulty. Given the potential cost of the repair, it didn't make sense given the value of the car. I appreciated his honest opinion. He said there was no charge, but I still tipped him for his time because he always takes great care of me. I have tried a few other shops in the area over the years, and had initial good experiences. However, they all eventually gave me an estimate I knew as wrong, or didn't do work they said they did. I've been going to Frank ever since, and trust him 100%. If you need a top notch mechanic, Frank is your guy!
