got a weird electronic problem since a few days on my 1999 S4:
Drove out of the garage last saturday, when the engine suddenly died.
Tried to fire it up again several times -> no way! Noticed, that the
yellow "EPC" light on the dashboard didn't come up as usual. So I got
me a cup of coffee and tried again after 15 minutes: Yellow EPC light
came, engine fired up! Drove the car for 30 minutes, no problem!
Returned home into the garage. Thought car and me just had a bad
Last morning things went worse, car didn't start at all. Called the
dealer, who came and pulled the codes. Told me that the power supply
for the ECU temporarily failed. He pulled some plugs, cleaned some
contacts and reconnected them -> Car started - fine business, read out
of the codes showed no more errors. Drove for the rest of the day
without any further problems.
Guess what happened this morning :-(
Maybe I should add that temperatures outside are getting lower now, we
had 5 degrees below zero last night... But its definitely not a
battery problem. Car has 80000 miles on the clock, ECU itself seems to
be OK. Could it really be a bad contact?
please replace "nospam" with "bw" to contact me directly
