Can Warped Rotor Causing 3 Amigos
Hello all,
I just got my first Land Rover a week and a half ago and after 350 miles of driving I got the three amigos alarm. After connecting a VAG-COM VCDS OBDII reader for VW I found the code p1590, with some research I learned that this is a rough terrain/ ABS fault. This makes sense because my front passenger rotor is a bit warped causing a little shake while driving. My question is what does the 3 amigos cause and how do I clear the code after replacing the rotor for it is currently a hard code which turns on as soon as the car is turned on.
Thanks

If your rotors are warped then get them true'd up or replaced and then use appropriate tool or take it to the dealer

My understanding has always been like this - https://blog.fcpeuro.com/warped-brak...-internet-myth
"Warped rotors" is a myth - pad deposits cause vibration - uneven wear etc but the rotor is rarely if ever going to actually "warp".
Tirerack was the first company that included pad bedding procedures in the rotors and pads I'd bought some time ago.
Properly bed the pads to the new rotors and very unlikely you'll ever have this problem again.
You can sometimes even resolve our vibration issue by doing the bedding process again - 0-60mph or so then about 80% brake over and over about 5-6 times.
Get those things really hot - they'll even smoke when new but it will do the trick and maybe clean it well enough to reduce or eliminate the vibration you're experiencing.

The code reader does not read LR faults. I'll have to find some way to gain access to a LR reader, or just start replacing parts starting with the cheapest. Might be a obvious answer but dose anyone know if a dealer will charge me to read the code?
Could be a bad shuttle valve switch, bad internal connection inside the WABCO Unit, that Option B would fix for next to nothing, or a wheel sensor/hub. Any higher end scan tool should read LR ABS codes.

PS, you could easily exceed the cost of an hours diagnostics in the chuck a part at it and hope lottery.

Since you are new to Rovers, look for an independent Land Rover specific shop in your area. Most larger cities have one or more and there is a directory on this site... They will charge you a diagnostic fee if you just do that but if you are willing to have them just fix it they won't charge a code reading fee, but you will pay less than a dealer. Dealers really don't want to see these any more and most "foreign car shops" aren't familiar with the peculiarities of the brand. They often see Rover drivers as ballers who will be making their next boat payment so ask questions and choose a shop wisely unless you plan to do the work yourself, then read as much of this forum as you can.

P38’s back in the day used to eat front rotors pretty good. Stop n go traffic and hard stops will in fact warp a rotor. I personally roll forward after a hard stop to move the rotor to a cooler part of the rotor.
An old timer told me the #1 factor to a warped rotor was during a hard stop & then keeping the rotor/pad in the same spot vs rolling forward & moving the hot spot out from between the pads. Not sure if it holds true, but I’ve driven a lot of vehicles driven by younger women & the front rotors were completely trashed & whenever you applied the brakes it vibrated badly.
