So, the other night we drove the Cabrio out to get some takeout, and since
it’s winter here we don’t drive it much, mostly the truck in the inclement
weather. So, anyway, I drive to a couple errands and it’s running great, new
TT Tuning exhaust, sounds great. We pull into the spot to get the food and I
shut it down and for a split second the idiot lights come on, then go off as
I pull out the key. I think nothing of it as I go in, but as I’m in line I
start thinking that it was unusual for them to go on when shutting the car
down.
So, back in the car, I start it up and the idiot lights are flashing now, a
few of them, I can’t recall which, and the speedo and tach needles are
bouncing along with the flashing. Idle is rock solid, car is running smooth,
drives fine. As I drive down the road the flashing & jumping continue and
I’m getting nervous, according to my wife (the primary Cabrio driver) that’s
never happened before. You’d have to be blind not to notice. Anyway, we
drive the 10 minutes home and about half way home it gets better, actually
showing the correct speed & RPM, then bouncing, then back to normal. It was
fine when we pulled in the driveway and I couldn’t get it to replicate the
problem. After two days it hasn’t happened again.
My concern is leaving my wife stranded somewhere or causing more problems by
letting it go. Any idea what it was/is? How to fix it?
Thanks in advance.
Josh


Hi Josh,

Not sure exactly which lights, but they’re the ones that’ll light up on the
dash if you stall the car, just below the speedo and tach. I think the gas,
check engine, abs, oil, I don’t know, I could be confusing the ones in my
truck too. But, it did happen again last night. My wife called me on her
drive to the gym, but it didn’t happen on the drive home.

It sounds like a loose ground in the electric system. If you have the
schematics, check all grounding points.
