Hi
Doe any one have any experience of using Bluetooth OBD scanner with Audi cars.
I have seen a few on eBay and AliExpress and you could use app to do fault finding, clearing errors etc.
I don't want to busy something that may not work or could cause damage.
Thanks

sorted byThey just read the basic codes & you have to opportunity to delete them until the engine management system picks them up again.
So what you are doing is deleting information, any fault still exists.
These cheap readers most often give you the most basic of codes. Example on a Peugeot it might give you an error code that relates to incorrect exhaust gases. Which can mean one of 100 things wrong.
If you want a proper diagnosis the buy a proper reader for a couple of hundred making sure its software does Audis or take it to an auto electrician
For VAG cars I can recommend Carista or OBDEleven. They're not cheap but will give you so much more information. I bought OBDEleven and it works well, although I have been frustrated that some tasks are now behind a subscription. I changed my start/stop battery last year, and while the device could handle the reprogramming, it now costs more money.
They took it to a one man band who had a proper scanner & it turned out to be the post cat converter Lambda sensor. The only sensor they couldn't reach so didn't replace.
This man diagnosed & fixed it for £160. Just because he had the right scanner & software for the make of car. (edited)
Thanks for all the help so far
It is worth it just to give it a go with a generic reader BUT do not expect the miracle answer.
If you cannot google the code & get the exact answer then waste no more time & money. Get an auto electrician in either via your local garage or ask on facebook if anyone knows one.
Plus I wouldn't bother with a bluetooth one. I would buy one with a lead & handheld. They will be generic too. (edited)
not cheap, but it does pretty much everything.
It is still treated as 'the standard' though, for example OBDEleven can actually accept long coding that originally came from VAGCOM/VCDS.
As said, it's expensive and to make modifications you have to pay. Much easier to use than VCDS which I used to have. Anything which is pulled up is also sent to VW group as part of the deal that they have. I suppose that it give good information to them for any common problems that may occur.
Have a look at the ELM327 chip, en.wikipedia.org/wik…327. That's one of the most common chips used in third party scanners. I've often thought about getting an Arduino (or even an oscilloscope) on to the OBD output, given the low speed I reckon you could do a fair bit. Although given that it's a request/response type arrangement I suspect you still need to know what to ask for!
