Chrysler 300c warning lights

[Lincrafts.com]

Not sure if anyone can help but our 2010 Chrysler has decided to light the dashboard up like a Christmas tree!
The ABS, ASR, ESP/BAS, brake warning light and traction control lights are on permanently and the parking assist keeps saying it isn't working and then decides it is for a bit and then it isn't again.
It goes into limp mode and then reverts back to normal but not for long and all the lights stay on.
The last time we took into the main dealers they quoted 6 grand for a job that cost just over a grand. After telling them if they were the last garage on earth I would buy a pushbike I won't be going back.
Any help or tips welcomed. Car is a pain in the proverbable but it does look good.

have you tried to disconnect the battery leads for 5 mins. when you reconnect them it may boot up the ecu.
