    I just had my car serviced at Bay Diagnostic and was presently surprised. The shop was clean and very orderly. The service was very very friendly from the owner Jordan and the workers. I was apprehensive when I first got there, but they put my fear to rest as soon as I got there. They do not sell you products or service you do not need. They are honest and efficient with all their customer. While waiting for my car, I spoke a few of their customers. They all had high praise for Bay Diagnostic. They do the job right and they stand by their repairs or services. I must agree with them,I am a believer.

    These guys were just great. Had a check engine light on, and needed oil change. They came to my house in Greenpoint, picked up my car, diagnosed the warning light, did some other scheduled maintenance and did the front brakes. Rates were very reasonable and then they brought my car back the next night. They were honest and pleasant to deal with . I will go back

    I am particularly concerned with ensuring that my BMW is cared for and mechanically perfect. I have used Bay Diagnostic for several years and trust them completely. For sure, prompt, courteous and knowledgable service, I highly recommend them.

    Since the Manhattan dealer's service, in my opinion, has deteriorated in recent years, I thought I would give Bay a try. As a former professional mechanic who still personally maintains three cars, I was very impressed. Spacious, clean shop, knowledgeable, friendy people and fair prices. I will definitely go to them in the future.

    Bay Diagnostic is a professionally run shop, staffed with curtious and knoledgable people. Jordan and Al are honest, sharp and capable guys who will assess, advise and repair any and all the needs of your vehicle. Even though my stage 2 Dinan - 2008 335xi is still under "Factory Warrenty", I had the rear sway bar replaced with the Dinan sway bar at Bay Diagnostic's. Perfect job! Also, my son's 2007 GTI had some work done there, with a scheduled AWE cat-back exhaust upgrade. All the customers I've ever met that come here are totally happy with their work and have nothing but possitive comments about Bay Diagonostic.

    Good shop, straightforward honest guys with very reasonable labor rates. I will be bringing my zhp back. Car runs great, especially with the Dinan stage 2 software and intake.

    Found Bay Diagnostics through a Roundel Magazine ad they placed, good place to have Bimmers repaired/diagnosed. I had a 2006 525i and I now own a 2011 535i (Sport Package) they change the oil and charge a good price/ they give you an estimate before working on the car. I recommend them to anyone with an Ultimate Driving Machine :-)

    I take great pride in my 530i - hand polish twice a year, check the tire pressure regularly, park indoors, avoid the rain when possible, etc. and I'm happy to have found Bay Diagnostic as my new independent mechanic. Friendly, knowlegable, on time, fair and recommended.

    Simple...just get a quote on the service you need/want....wait 3 or 4 up with your car....they are happy to see you, even if you show up too early...then they charge you exactly what they quoted you a while back and they even offer to wait for your if you are running late to pick up your car!!!....That is service and HONESTY....with a smile, which is not necessary but it helps....thanks guys...will be back soon. Impeccable service, Impeccable shop and office.

    I went to Bay Diagnostics for oil change and transmission fluid check for my BMW 740iL. The service was prompt and my receipt showed "oil change, all fluid checked". However my transmission fluid was never ckecked as I found out later when I took my car to another repair shop. They added 2.5 quarts of the special Shell oil.which I supplied and I was present when they put it in. They also showed me a small leak from the rear transmission seal.

    Bay Diagnostics did not check my transmission fluid, did not mentioned anything about oil leak eventhough they had the car on the lift and now I wonder about my $100 oil change.

    When the battery on my Land Rover failed to start my car, my dealer suggested a lot of different things. I had a brand new battery put in, the radio checked for drains and the alternator replaced. The battery still would not last over night. A friend recommended Bay Diagnostics for their careful and honest service.

    They found the problem, a rare glitch in my AC wiring was draining the battery. It was quickly repaired by the no nonsense, friendly staff. If I had known about them sooner I would have never dealt with the dealer, but I am glad to know of them now!

    I was referred to this shop from my mechanic due to an issue with my supercharger system which we couldn't diagnose. We finally determined my fuel trims needed to be reset before we could move forward but there aren't many shops which can do this. I found a few shops with Snapon Motivs but they could only read my trims (1996 M3) but not reset them. Finally the guys here at Bay Diagnostic did exactly that. Friendly, quick service and it's a nice, clean shop to boot. They definitely gave me a good deal and I'd certainly recommend them to anyone, especially if you need higher end diagnostic and ECU work done which they can do using their BMW-specific equipment like the Autologic and BMW GT1, not many shops have this equipment so they're definitely an asset to the Long Island/NYC BMW community.
