Finding the Best OBD2 Scanner on AliExpress: A User’s Honest Review

For years, I’ve relied on a DS150e OBD2 scanner, and it’s consistently impressed me across numerous vehicles. From basic maintenance on my previous car – constantly resolving those persistent EGR fault codes caused by a software quirk – to more complex diagnostics, this tool has been invaluable. Even a brand-new EGR unit from the dealership couldn’t permanently fix the issue on a friend’s car with the same problem, highlighting the scanner’s crucial role in identifying and clearing these ghost faults.

Over time, I’ve lent my DS150e to friends and family. One, a retired mechanic who still enjoys tinkering, was particularly impressed, especially since he couldn’t take his dealership-grade diagnostic unit home after retirement. He ended up buying his own after experiencing the convenience and capability of the DS150e. My brother-in-law also borrowed it to clear a multitude of fault codes after a car repair and was equally impressed, likely considering a purchase himself if he didn’t have easy access to mine!

On my current MINI, the DS150e has continued to save me money and hassle. I encountered an EGR valve code a couple of times, which it quickly cleared. More significantly, a concerning airbag light once illuminated, disabling all airbags and safety systems. My standard Bluetooth Android reader was useless, unable to even detect, let alone clear, the codes. I was bracing for expensive repairs. It turned out to be a blown boot light fuse! This seemingly minor issue caused the passenger airbag disabled light to malfunction, triggering the airbag module and throwing up numerous error codes. Replacing the fuse and fixing the light wasn’t enough; the fault codes needed clearing, and the DS150e handled it perfectly.

It’s worth noting that the additional cables often included with these units are generally unnecessary unless you’re working on older vehicles that predate OBD standardization, like older BMWs. For most cars newer than the mid-1990s when OBD ports became standard, the unit’s standard OBD plug is all you need. The extra cables are simply adapters for older, proprietary plugs.

If you’re looking for a similar unit at an even more affordable price point, there are options available on AliExpress. I’ve had this unit in my favorites for a while. While I haven’t purchased it yet (my current DS150e is still going strong!), it’s a tempting upgrade. I’m particularly drawn to the Bluetooth version, typically around £35 plus postage, although prices fluctuate.

Speaking of alternatives, I’ve also tried the Carista Bluetooth unit twice. Both times were disappointing. The first time, I returned it within a week because its coding features were far less comprehensive than advertised. The second time, years later, I returned it on the same day I received it. The software had become cluttered, and basic functions like reading and clearing codes were now behind a subscription paywall. It even falsely detected error codes that weren’t present and demanded a subscription to clear them. While I initially wanted it for its coding capabilities (specifically to disable bulb checking after switching to LEDs), the coding options had actually decreased since my first attempt, including the missing light checking settings. Avoid Carista. Save your money and look for a better OBD2 scanner elsewhere, perhaps consider the DS150e or similar units available on AliExpress for genuine value and functionality.
