John Harry, Polegate, UKVery sturdy and well made kit, I own a 2017 Discovery Sport, and a 2020 Range Rover, so the V4 LR tool will cover me for both tools and so far has reset the oil service on the Discovery Sport, and given that it's a Land Rover, i fully expect there to be issues ahead (there always is) but gives me peace of mind knowing this tool will cover me. Thinking about getting another one so I can keep one in each car, possibly overkill i will see. Thanks for your help guys @ Diagnostic World.
Andrew Cottam, Preston, UKNeeded to carry out a DPF regeneration on my Range Rover but the garage main dealer quoting me a small fortune, I figured to buy this tool and keep it is cheaper, so now i carried out the DPF regeneration, and still have the tool which i can probably use in future to save me more money. It's a no brainer really. The DPF regen was actually easier than i thought, just followed the on screen instructions, step by step it tells you what to do. Cheers
Wendy Wilson, Lowestoft , UKDreaded ADBLUE countdown message was showing on dash every engine start, this LR V4.0 was able to reset this easily so happy with it. (It was a Range Rover Evoque) All cool, no problems and fast delivery.
Jeremy Marsh, New Jersey, USADelivered to me in USA pretty fast, they used UPS which is a very good direct service. The tool works exactly as supposed to straight from the box, I have an older L322 Range Rover with a check engine light and newer Discovery with the 3 Amigo's (all now sorted) yes these Land Rovers are expensive to run but i do love them. Cheers.
Leslie Dumitrescu, Petersfield, UKDelivery was a bit slower than had hoped but it was over the christmas period so I think a lot of stuff was delayed. When i finally got my hands on the tool, I was able to reset the airbag warning light and message on our Jaguar XJ. It gave a fault code and a description, but I couldnt understand why it came on in the first place. I was able to reset the warning light without physically fixing anything so I can only assume it was an intermittant fault and will keep an eye on it. Thank you guys Diagnostic World team.
Eddie Saimbji, Slough, UKReally happy with my new tool it is a big upgrade from my last tool (LR V1.0) which i had for my Freelander 2. I sold that car and now got the new Defender which is a beast, but also not without some niggling issues. Airbag light twice, ABS faults intermittant. The car just does what it wants but the V4 tool has always been able to reset them. I have the car booked into Land Rover for a software update so hopefully they can stop the intermitant faults but until then, this tool will do the job. Thanks Alistair & Diagnostic World staff for helping me out.
