Wayne Smith, Swadlincote, UKThank you for the tool. I was able to do a headlight adaption, and look into a check engine light relating to the glowplugs. Nice touch screen and updates are super easy this time, I remember my MB V2.0 where I had to plug it into my laptop to do the updates and for this tool you just connect to your wifi network, press update and its all done, so so easy. I keep this in the car at all times as we do quite a few road trips so it's very handy to keep with all of the time.
Dean Moore, Durham, UKGreat product and gives me full access to my Mercedes A Class (A250) which currently has an issue with the stability system. I have the codes and description to look into in greater detail very soon. All good though. well made and fast delivery.
Tina Jhalera, Milton Keynes, UKA good equipment for husband who said it can let he turn off the light for the engine. It is all turn off now with some clicks later and car run good because it was bumpy before when ligh was on. The man Diagnostic World help to show tools that work. It was Mercede c classic.
Jevon Rodgers, Rouen, FranceDelivered to me in France fast. We are touring France in our G Wagon but faced limp mode becuse of an engine sensor which has all now been fitted and reset, but couldn't have done it without the V4 Mercedes tool. Great kit and when you consider the price of dealership (and even specialists these days) this is a bargain but of kit. Cheers Alistair at DW for helping to get the right tool, and delivered to me fast.
Raymond Batchelor, Southampton, UKThe garage are just priced way out of my league now so I will try to do as much as possible without them. That's where this tool comes in. My E Class estate is wonderful (W211) but is starting to show its age. I would like to kleep this car running forever starting with a service, and also an airbag sensor (for the airbag light on dash) Thanks to everybody at Diagnosis World for the first class help & support.
Mark Simmons, Warwick, UKSuperb tool. My wife has al older B Class, and I have the W206 C Class. The tool covers both cars, and I recently had the adblue countdown start on engine start up, but this tool was able to reset that which i think the garage charge quite a bit for. Was all simple to do, just select the adblue icon from the service menu, follow the on screen steps to reset it.
