Hey guys long time lurker first time poster in this thread.
I have a 2013 P85+ with all kinds of problems. It wasn't in an accident it just happened some day all of a sudden. It is a Euro car. Main errors being;
- Regenerative braking disabled
- Stability Control Disabled
- Traction Control Disabled
When driving the car sometimes the steering wheel becomes heavy like the car was off, it also really has regen disabled so it is dangerous to drive like this. So I want to solve it. Here's what I have done so far;
1) Got the car in diagnostics mode and checked the errors. Here they are; (I wish I could decipher these meanings to a specific part)
2) Checked the front wheel speed sensors. It had oil/grease on them so I cleaned the sensors + behind the brake discs where sensors reside. Not solved.
3) Changed the ESC cluster underneath the center console with a working one. Did service-redeploy, didn't work.
4) Disconnected 12V battery and checked the fuses, mainly the ABS motor fuse and power steering fuse. Which are a pain in the ass because not only is it on top of the 12V battery fuse location. (tears and blood to reach) Those fuses are even under the 6 center fuses so to reach the second level of fuses you remove one side's wires for all 6 fuses on the centre. Checked those and they were fine.
After putting the car back together the car got worse now because it won't start! I have the 'Car needs service' & 'pull over safely' errors. Car starts, so it isn't in off state but gear doesn't shift from P to anything else. However tow mode can be enabled. I thought it was a dying 12V battery so I charged the 12V battery for a while and it didn't work. Rechecked the HV loop thinking I might have not connected it properly but it was proper.
So the car is at even a worse state than I started it. Any suggestion is more than welcomed. My only remaining option was to check the rear wheel speed sensors but that is an agony in and on its own. However I'm not even at that point anymore because I have to start the car again first. So, please help.
