Don't hesitate, Buy One, your bank balance will thank you for it!!!
I had several problems with my Mercedes and the garage (a national chain) spent several hours with the car and finally pronounced it to have more problems than it actually did.
The cost of all the repairs was not calculated but was going to be substantial and open ended from the discussion I had with them.
The car had gone into limp mode so it was struggling quiet badly with no turbo, the temptation was to say just get on with it, but thankfully I decided to order this diagnostic machine because I wasn't happy with the diagnosis I was given!
The tool arrived much faster than anticipated and I had it connected to the car within a few minutes of arrival, I was astonished how simple this was to do, just spend a little time to identify the exact car model - this bit is very important, I don't think the garage had correctly identified the car and this may be why they misinterpreted the data?
The main problem was a disconnected pipe to a sensor on the DPF, the car was fixed literally in under a minute, no more limp mode!
The repair could have easily cost several times the cost of this diagnostic tool and I would have been no wiser, so as the title implies this is an invaluable tool which could pay for itself many times over.
Having had this tool for a couple of weeks now, I find it fascinating how much information can be gleaned from it about the fitness of your vehicle, I cannot recommend this tool enough, buy one...
