EPC light on & speed warning

Post by BurgerBarley » Sun Jun 09, 2019 11:48 pm

Hi everyone.

I'm a new member from Auckland, NZ with a 2007 RS4 Advant b7.

Only had the car 1 month and driving to work this morning I got an EPC warning light, and then randomly at 60km/h I kept getting speed warnings, when I didn't have any speed warnings set. The car still drove fine and never went into limp mode. Didnt get any more faults until I parked up at work, switched the car off and back on and it told me coolant temp, oil pressure, brake fluid level and a few others all on the start up.

I haven't got it home to scan the codes yet, but suspect it's moisture in the ecu/relays, or the 614 relays not supplying enough power to a bunch of things.

Anyone had this problem before? Any suggestions to diagnose this quickly?

All comments and tips greatly appreciated!

I had lots of random error warnings once and it turned out my battery needed replacing. When I ran a scan it showed up lots of errors throughout the car.

Might be worth charging it up overnight to see if it clears the faults?
