Good fault finder
Really brilliant diagnostic kit. East to plug and play. Options to identify car make and model. Brought up old cleared faults as well as new faults linked to the engine management light that annoyingly appeared on our Mercedes. Worked out quickly what it was linked to, save a very expensive garage trip. I havent had much comparison to alternative products but I was very pleased at the user friendly interface and the design and build of the device itself. Comes in a nice carry case too

Excellent
Since receiving I have only tested basic features like scanning for error codes on a Volvo EX30, Fiat 500 and BMW F30 which this performed fine on all 3. It also allowed me to change parameters and code features like disabling stop start. Then out of no where my F30 kept going into limp mode and I used this to attempt to diagnose the issue. Codes were pointing to a fuel pump issue but it was a rather generic code (the fault of BMW not the scanner) but I was then able to monitor the live readings of the HPFP and it was clear that was at fault. Let my garage know and they confirmed it and so saved me a diagnostics charge. A really brilliant tool for those who are repairing cars as a hobby/living.

Professional-Grade Bidirectional OBD2 Scanner with Outstanding Features
The Thinkcar ThinkScan 689 is clearly designed with professional auto mechanics and repair shops in mind, but it can also be a fantastic tool for serious DIY mechanics who have the knowledge to use its wide range of functions. For the average non-specialist user, much of the advanced functionality would likely go unused, but for those with the skills to utilise it, this scanner is an incredibly powerful piece of kit. What sets it apart from budget scanners is the sheer amount of information it provides. It picked up a glow plug issue on my 2017 BMW X6 that cheaper scanners had completely missed(something only ista reported). The bidirectional capability is a real game changer, allowing you to not only read data but also perform active tests and send commands to vehicle systems. The WiFi makes software updates effortless, and the ability to email reports directly from the scanner is a huge time-saver. The inbuilt Chrome browser is another handy addition, letting you quickly search for additional fault code details without needing a separate device. The VIN scan worked flawlessly every time, and the touchscreen is responsive and fluid. Practical touches include a robust design with impact protection, a hanger for the steering wheel, and a well-designed case that keeps the unit, charging cable and documents safe. Battery life is excellent, with convenient USB-C charging. Add to that lifetime free updates, and it’s a tool that will keep delivering long-term value. Pros Targeted at professionals but suitable for knowledgeable DIY mechanics WiFi makes updates quick and easy Can email reports directly from the unit Inbuilt Chrome browser for instant fault research Much more detail than budget scanners Detected faults cheaper scanners missed (e.g. BMW X6 glow plug issue) Bidirectional functionality is a real game changer Excellent battery life with USB-C charging Lifetime updates included Robust build with impact protection and steering wheel hanger Protective case for storage and transport VIN scan worked with 100% success Smooth, responsive touch screen Cons None

Car diagnostic scanner
I got this ThinkCar ThinkScan for our cars at home. My husband has used it on both of our recently purchased cars to make sure they were in good condition. I personally don’t have much knowledge about how to use it but after watching him it actually seems quite easy to set up. It gives you step-by-step instructions, so even if you’re not experienced, you can still manage it. It’s already done a full scan of both cars and told us exactly what we needed to do. On one of the cars, it even indicated that it needed a full service, which I got done so that was really helpful. It performs loads of useful diagnostics and what I love most is how much money it can save. In the past, whenever I had car issues, I’d have to take it to a garage just for a diagnostic check which would cost anywhere from £50 to £80. After paying that, you almost feel obliged to get the repair done there because you’ve already spent the money. This tool is brilliant because you can run diagnostics at home and if there’s a problem you can shop around for parts or call a few garages to get quotes. It gives you a much better idea of what you should expect to pay. It really is amazing and I think it’s going to come in very handy for our cars in the future. We’ve only used it a couple of times so far, but it’s already given us great results. I’m really pleased with it and although it’s a bit pricey I see it as a great investment in the long run as it will definitely save money because sometimes just one garage visit can cost more than this device. If you know even a little bit about cars, it’s absolutely worth having.

Gute Verarbeitung, erkennt so ziemlich alle gängigen Autohersteller. Steuergeräte lassen sich auslesen, ansteuern. Kostenlose Updates. Für Hobbymechaniker völlig ausreichend.
