Sacha Kurochka
Fantastic service. Very knowledgeable and friendly. It’s in my honest opinion, prices are very reasonable and affordable. Had a tune-up done on my Mercedes, oil change plugs tire rotation and it was a fraction of the cost from the dealer. I strongly recommend.

Engine Repair FAQ
It depends on the age, condition, and value of the vehicle. In many cases, rebuilding or replacing the engine can extend the life of the car significantly at a lower cost than buying a new vehicle. We can help you compare repair costs versus replacement options so you can make an informed decision.
Even if your manufacturer does not list a service interval, regular transmission fluid inspection and replacement can help extend the life of your transmission, improve shifting performance, and reduce the risk of costly repairs.
A worn timing chain can cause engine rattling during startup, rough idling, poor engine performance, misfires, or the check engine light to illuminate. Ignoring these symptoms can lead to severe engine damage if the timing chain fails. If you notice any of these warning signs, it’s important to have your vehicle inspected as soon as possible.
Over time, carbon deposits can build up inside the engine, particularly on the intake valves of direct-injection engines commonly found in BMW, Audi, Volkswagen, MINI, and Mercedes-Benz vehicles. Excessive carbon buildup can reduce performance, cause rough idling, decrease fuel efficiency, and trigger check engine lights. Professional carbon cleaning removes these deposits, helping restore engine performance and improve drivability.
Spark plugs and fuel injectors play a vital role in your engine’s performance and fuel efficiency. Over time, worn spark plugs can cause hard starting, rough idling, engine misfires, poor acceleration, and reduced fuel economy. Dirty or clogged fuel injectors can lead to similar symptoms by restricting fuel flow and disrupting the proper air-fuel mixture. If you’re experiencing these issues or your vehicle is due for scheduled maintenance, we can inspect your ignition and fuel systems and recommend spark plug replacement, fuel injector cleaning, or injector replacement as needed.
Yes. Many transmission issues can be repaired by replacing worn components such as sensors, seals, solenoids, or mechatronic units rather than replacing the entire transmission. We’ll perform a complete diagnostic inspection and recommend the most cost-effective solution for your vehicle.
