Help! I have finally got my dream car but have a few issues that I am sure may have happened to others. ESP light has been on for a few weeks. The other day, St Paddys Day-no luck of the Irish for me. Brake light came on, Speedometer stopped reading anything, check engine light and ESP. Pulled over put it in park and it would not shift out into gear. Used the tool and got in into first and drove slowly the next few miles home. Wrench is showing a 700 number. Spoiler would not go down. A few days later all the lights still showing, got the top up and spoiler down. Today I was going to have it towed and it drove fine only the ESP light still on. The put the diagnostic readers, three types on and got no codes. Left the car and am now at there mercy! HELP

 

You shoulda tried a new battery or cleaned the battery cable connections at the battery and the fenderwell first !

 

I've repaired a few relay control modules that gave the same symptoms you've described.
Check the battery to ensure that it is GOOD first.
Battery good? Great!

Next, remove the RCM then remove the cover.

Reattach connectors then turn the key to the ON position.
Engine and traction relays should be in the closed position. If not, you have a bad relay or relays.
