Bluetooth OBDII and Smartphone - brilliant

Wife's car was shuddering and had the check engine light on.

Figured that it was a failed ignition coil, as symptoms were the same as for a similar problem last month (which an Indy charged €120 to diagnose and replace).

Anyway, I downloaded a free OBD App for Android and picked up a Bluetooth ELM327 OBD dongle today (€20 from a bloke on Adverts.ie)

Problem diagnosed in 20 seconds from my phone!

Fault: Ignition Coil #2 misfire.

Spot on - replaced the coil (€31 from Micksgarage) - problem was solved.

Used the same app to clear the fault code and turn off the light.

Very impressed, and works on nearly every car with OBDII.

Nice one!

Or be a little bit more old fashioned like myself and use a handheld wired OBDII reader (about €25 on eBay)

Thats what I started looking for until a friend at work told me about the Bluetooth version.

An added feature is that even the most basic apps come up with the full description, not just the fault code number.

The more advanced apps (still free) allow you to see everything from oil temp, coolant temp, to throttle position, air flow and on and on and on.

Also lets you know if your O2 sensor is working.

Works alright, doesn't have great range on the bluetooth though. I've tried it with Torque Pro (works fine, although some dials update slowly) - but trying to use it with ScanXL Professional on a laptop via bluetooth... doesn't work so well. Not sure how much of that is the laptop bluetooth software not being great, ScanXL being buggy, or the elm327 interface.

There is an overwhelming choice of dongles out there. I did a goggle search for elm327 Bluetooth in Ireland. First result was an ad on Adverts.is

I was able to meet the seller same day.


I have 2 free apps installed: Torque and Carista.

The Carista app is dead simple with just 2 buttons: DETECT FAULTS and RESET FAULTS.
I used this to diagnose and then clear the fault code.

Which one did you go for? There's several different types and the seller you mention (if this is the same guy) has 2 of them in the top results...

This one and this one. He (again based on the username) also seems to have another one on ebay

Not sure what the difference is?

The ELM 327 is a great bit of kit for the price of it. The Memoscan U480 also works well - I use one myself - and the price and simplicity is hard to beat:

It was neither of those, as it was a different seller. He said it was his last one.

To be honest, the technology involved is so matured at this stage, that I can't see you going wrong with any of them.

I dont have an iPhone, so sorry.

I'd just do an itunes search for OBD2 and see what it comes up with.

Toruqe Pro seems very capable, and only costs a few Euro.
