Hi Fellas, i've been getting the horrible intermittent blinking yellow to red suspension fault with the code "C1119-62(AF) Hydraulic Pressure - Algorithm Based Failure - Signal Compare Failure". I was just wondering if anyone has a diagram of the DRS system, i'm trying to prepare myself to look over the system this weekend.

This really only happens when it rains or the undercarriage is wet like after a good wash. If i shut the car off and wait a few min it goes away but it comes back. It's probably only happened to me a handful of times but it always goes away after a dry day. I do also notice i must be leaking fluid because i've had to top off the sytem once or twice before which makes me want to go through the lines to confirm any leaks. I've read that a leak in the high pressure primary circuit/reservoir/secondary circuit could cause this fault.
