I read on their website that Arnott has a two-year warranty, not a lifetime warranty. Am I correct? https://www.arnottindustries.com/warranty/

Yes, I checked the web site and it is true. To add to my saga with Arnott after all of the problems with a bad strut the front end of my car would be all the way down in the morning but would pump up quickly once the car was started. This started a couple of months ago. I couldn't get it into my Indy for a few weeks so continued to drive it. Well, it got to where it wouldn't raise at all and I got a "Do Not Drive" message. When I took it in they had a valve body unit in stock and swapped that out but didn't solve the problem. The compressor was running but wasn't building pressure. Fortunately I had kept the original compressor and they installed it and it works great. Evidently the Arnott valve body was bad causing the compressor to run and burn itself out. Arnott has replaced both units under warranty although I still have the old compressor in place and it's working fine. So last year I replaced all four struts, the valve body and compressor with Arnott units. Of those 6 parts, 3 of them were bad and had to be replaced - a 50% failure rate! I have the replacement compressor still in the box and haven't decided if I should sell it or hold on to it. Anyone looking for a new in box compressor I'll give you a good price!! I've had it with Arnott parts!

both my drive and the other one I can borrow easily are not flat so trying to get power to hold volts up and a flat surface is a big issue for me
trying gearbox and TC adaptions is one - the incredible ideas the tools says to follow are impossible to complete - on a rolling road maybe - on the public highway u run out of road or it locks up the TC and throws out the limits they impose to learn it and save it (go for a drive with xentry hooked up - now apply throttle with less torque applied than a 1/4g feather on the throttle peddle - drive up the road and let it go up the box inside a set torque range - where going over a 2mm high pebble sends it straight in the red zone or the TC clutch lock up cuts in and immediately throws the bar chart marker off the screen into the car beside you)
