Steve Dinan Auto Tech

Well, if you have a BMW, you may know the the name Dinan.
They design and manufacture high performance parts for BMW’s.
And, they also service them.
Recently, I needed some work done and decided to roll the dice and tried this place.
Result: I received quality work and was treated like a valuable customer.
My problem: the clutch pedal stuck to the floor. Came in to have a clutch slave cylinder replaced.
Results: my clutch works good.
Their large shop area looked clean and spacious.
Price: better than the dealership.
Bonus: free shuttle locally. Two shops: Mountain View and Campbell.
Customer service: fine.
Store: very nice; cool Dinan products for you to oogle and touch. The customer waiting area is comfortable and has Wi-​Fi, beverages and espresso.

No charge! Brought my 528 in during the Holidays as I had been bothered by the gear noise from turning sharp right. Within 30 seconds after opening up the hood I was told my power steering fluid was practically gone. A free gulp came within 1 minute and my car was fixed. Woohoo indeed! Highly recommended for their integrity and fast response!

EDIT:
I had a lengthy review on here with some bad experience I had with Dinan. To sum things up, I wanted my car SMG software coded, but just got my car options reset which wasted my time and money. I also had a very costly repair done which didn’t go 100% well and required me to actually work on my car after the repair (My O2 were plugged back in to the wrong locations, the car ran but threw service codes because it thinks my intake air quality is from China). I chose to remove the lengthy version because I did not want the business to be punished, just for them to hear my concerns.
What changed my mind was that Scott called me and tried to set things right by offering to compensate my time for the O2 sensors with discounted services. I have most of my maintenance done so I will not need any services for a while, but I still appreciate the gesture. This increases my confidence that they will honor mistakes by trying to set things right, I’m adding two extra stars. Scott was also concerned about my perception on how things were handled and thought my judgement was unfair. I will admit that the situation was complicated and I’m more willing to forgive any oversight than before, but I still wish I had the tear down estimate.

They worked on my car and did a great job. Fast, polite and came in under the estimate.
There was a misunderstanding during a subsequent phone call to get a quote which caused me to Unilocal a less than positive review. However, Scott called and professionally discussed and clarified the issue. I respect and very much appreciate him reaching out and taking the time to discuss the issue at-​hand… A true pro!
They’ve earned my business back. I look forward to working with them again.

I’ve taken my car here a few times and have been treated well. Scott has been great, and also very fair with diagnostic charges. And after a very short repair, they even washed my car, which it needed very badly.

What a friendly group of people. I’m a Florida transplant and some of the prices out here are a shock, yikes! I couldn’t believe how much BMW wanted for an oil change so I looked around and found Dinan who specialize in BMW’s, they’re prices are so reasonable and well worth the visit.

As you read this, bear in mind that each day that they had my car, I had to call them an average of 3 times. Each time I was told that «Scott would call me back in 5 minutes». He never did. Not even once. On average he would answer on the third call. I took my 328i there back in June of 2014. Shortly there after, the splash guard under the hood came loose and was scraping along 101 South. I took it back in and asked them to replace the guard which was now ruined and to diagnose a rough idle. They replaced some solenoids and charged me $ 600. I could tell it was still idling rough before I even got home. I took it back and after a couple of more days they still had not resolved the issue so I got it back with the rough idle. 3 weeks ago I hit a pot hole which triggered the flat tire sensor. I took it to them and they told me that they couldn’t fix it until I got new tires. I got the tires and took it back at the beginning of this week, mentioning that it was still idling rough. They did nothing on Monday or half of Tuesday even though I had an appt. On my lucky 3^rd call Tuesday afternoon, Scott informed me that my car needed an $ 1100 part. IE. the tires had nothing to do with it. On lucky call 3 on Wednesday Scott informed me that they were having a tough time finding the part, but would have one in the morning. At 8:45 this morning I told Scott that I would be by at 3:30 to pick up the car. «No problem, it’s only an hour long job.» When I arrived at 3:30 I was told they needed another half hour. Needless to say, I won’t be going back.

These guys snuck in about $ 400 worth of repairs. When their customer service called me I told them, they proceeded to try to sell me more repairs and didn’t even address my concerns. I used to go to A&E (which was bought out by Dinan) they were great, these guys are not. I don’t reccomend these guys.

I’m updating my review because Dinan has contacted me via phone and email to apologize for missing my appointment. I’m on the fence about giving Dinan another shot (partly due to other reviews and partly because it’s not a convenient location from home or work) but I do greatly appreciate their efforts to reach out and make things right.

I worship the ground these guys walk on! They just saved me almost 1k today.
My BMW started making a weird noise… like something was loose and it was under extended warranty. I brought the car into BMW Mountain View (after waiting several days for an appointment) and, as usual, there is never a loaner available. That was a big come on when they sold me the extended warranty. BMW told me I needed 2 new shocks as the left one could not be bolted back because of the threads and it would cost me $ 1k. Luckily I had the where with all to get a second opinion at Dinan. They were able to bolt my rear left shock back without a problem in under one hour and just charged me for labor! Unbelievable!
Thank you for a job well done Dinan! Keep up the good work. I have just become a member of your Unilocal Fan Club!

My car today overheated on my way to work. I called my insurance company and had the car towed to Dinan.
Service was great again. The time it took to check in and drop off my car was very short and I was on my way. They updated me at the end of the day on the status of the diagnostic and when the repair should be completed.

We go here to get our BMW worked on and they are very good! The place is clean and they are specialists in the field! We just got our air conditioning worked on, but they have done it all and are good at it! We highly recommend them!

The parts department at the Dinan Campbell Service Center has what you need for your BMW! Bob Martuccio the parts manager has been in the BMW parts business for over 30 years and can track down almost anything on BMW.

Fast, friendly service that really works with you.
I called in to make an appointment and got the time that I wanted just a week later. This is great considering how long it can take to get a dealership appointment around here. Shuttle service to my office after dropping off my car and a pickup on the return leg, all working with my busy schedule.
Everybody in this office knows their stuff. They diagnosed the cause of a squeak, informed me about upcoming service with no pressure, and even let me know about an issue with one of my turbos. A really good experience all around.
But the kicker is this: they knew to ask whether my car was purchased new or CPO.
As a CPO car, the issue with my turbo is still covered by the factory. The team at Dinan Campbell even called over to Stevens Creek to let them know to watch for my call and check the books for the best dates to get a loaner while the turbo gets fixed. Amazing.
Thoughtful, expert service from folks who are passionate about the product and building on Dinan’s reputation in the BMW community. I used to drive up to Concord BMW for routine maintenance and service. From now on, I’m booking at Dinan.

This is the house that Steve Dinan built. If you know BMW’s and you want the best to work on your car, you bring it here. Great guys, great service. Great workmanship.
P. S. Steve… you have no idea how sorry I am about the S3-​R. Damn it!!!

I love this place! Very clean, friendly and professional.
I recently brought my BMW in for an oil change and general maintenance. The staff was wonderful. Sonny greeted me with a smile and made me feel he was happy to get my business. The building was clean as was the restroom (which is a really big deal for me. If a restroom is gross, there’s a good chance I won’t be returning). My wait was short and the work was done right and at a good price.
I will absolutely be returning and recommending Dinan to all my friends.

The general manager of Dinan shops called me and wanted to hear more about my experience after reading my review. I appreciate the call and wanting to make sure their customers are satisfied. I will probably give them another chance because of the phone call and also location is very convenient.

Incompetent and shady.
Incompetent because they blew off my reported concerns about an issue — something that turned out to be a very dangerous leak — and utlimately had to get it fixed by Stevens Creek BMW.
Shady — for many reasons. They installed a faulty part (which happens), and my car had to be towed in for re-​repair, and they would not pay for the tow. Later, they told me their policy is to pay for a tow in these situations… but still no reimbursement.
But the kicker that makes me think of Dinan every morning when I start my car is this: normally, my BMW is factory set for an oil inspection warning at about 15,000 miles. Dinan changed mine to 3,000. No discussion — just sort of snuck that in there. Did they think I wouldn’t notice? Were they hoping I would dutifully bring my car in every 3,000 miles so they can get more revenue from me?

I judge a Business by their communication and customer service quality. If they even have the best quality products or services its worthless to me if they don’t put any effort on communicating with me for my question or concerns.
I sent an Email to both corporate facilities (Campbell and Mountain view) a week ago and i still have not heard anything from them. This gave me a bad impression of Dinan and i would rather give my business to a shop that appreciates my business and replies within a few hours or even a couple days. i have been to their campbell facility once and the person behind the counter was on the phone for 15 minutes and did not even acknowledge me so i just left.
It is too bad since i am a big fan of Steve Dinan and he is one of the individuals that inspires me.
Hope this helps Unilocalers !
UPDATE: Dinan Managers contacted me shortly after i posted this review. As far as Emails i sent them, they explained the emails were filtered by their email program and was sent to Spam folder. They also apologized for my initial experience at Dinan in Campbell. I added 2 more stars for the efforts on their part to resolve the issue. i will update this review once i get the chance to try them out.

I’m always really weary of going somewhere to get work done on my car with the fear of getting ripped off and just don’t particularly like dealing with the dealership… but what can you do when your ride needs a check up?
I had a check engine light come on in my 335, called up the dealership and they told me it’d be a week before they could have me come in. I wasn’t ready to wait a week since I had no idea what was wrong with it.
I went into Dinan and Sonny helped me out. He checked everything out for me, and the light was just because of my gas cap. He also changed out my wiper blades since it’s been raining, and noticed that one of my brake lights were out. Now i’m back on the road, as good as new.
I thought I’d end up paying an arm and a leg for repairs, but Sonny checked everything out and it was painless. He was super helpful, and explained why the light came on. It’s great to know what’s going on and not just get rushed out or taken advantage of with a ton of extra stuff you don’t need. I’ll definitely be back for anything else that I need done.
if you need any work done, go and ask for Sonny. Like I said early, it’s hard finding a place you can trust with good customer service in the automotive.
I’m thinking I want to go back and get that Stage 1… vroom vroom…
