Customer Reviews
Bought this after a garage quoted me £60 just to plug their machine in. This car diagnostic scanner read the fault code instantly (it was a loose fuel cap) and I cleared the check engine light myself. Saved me time and money!
The built-in car key battery tester is brilliant. I've never seen an OBD2 scanner with this feature before. Tested my wife's key which had been playing up, confirmed the battery was weak, changed it, and it works perfectly now.
A very solid vehicle fault code reader. The screen is clear and it's incredibly easy to use without messing around with phone apps. My only minor gripe is I wish the cable was slightly longer, but it reaches perfectly fine from the footwell.
Much better than the Ancel scanner I had previously. The menus are straightforward, and it connected to my 2012 Ford Fiesta diesel without any issues. Great for checking I/M readiness before my MOT.
Does exactly what it says on the tin. Read the EOBD fault codes on my VW Golf quickly. The screen can be a tiny bit hard to read in direct bright sunlight, but for a handheld OBD2 scanner at this price, it's fantastic.
I know nothing about cars, but this car error code reader is so beginner-friendly. The manual is clear, and it helped me figure out an oxygen sensor issue so I didn't get ripped off at the mechanic.
Excellent piece of kit. I love that it's a wired OBD2 scanner-no Bluetooth dropping out or apps asking for accounts. Just plug it in, read the engine fault reader data, and you're done. Highly recommended for any UK driver.
