Bought the adaptor and got the 1 month free. App seems ok (but slow to scan compared to others) but didn't get much of a chance to use it, just went to use it again and maybe pay the upgrade fee but it now £109 a year!! The amount of times I will use this makes it way too expensive as there is no way to just pay by the month. Think I will bin the adaptor and use a cheaper app.

$68 a year, seriously?!. We are justified this by being told that it would pay for itself with the second use, assuming of course it's used more than twice every year!. But let's be honest, if you are an end user having to consistently use this app on one car that many times then perhaps it's time to consider a more reliable car!. I can get two full diagnostic reads locally from an independent for the cost of one annual sub, plus you should only need to change the comfort settings the once!.

Being in diagnostics this is fine if your using it to make money. The sub is high and if you have trouble connecting to a car. Online support does not respond whilst your plugged into the car. They reply 3 to 8hrs later. We can't sit in a customer's car all day. There are other devices on the market that have dug me out of a hole when this fails to work. They just launched a Carly universal adapter to work with all cars. BMW not only needs the BMW adaptor it also requires the interface unit
