dash dic and guages going berzerk
well after 2-1/2 years of bliss my car is throwing a fit. i took the cover off today, removed the battery tender and brought the car out of storage. after a nice 50 mile ride i shut the car off in the driveway. it restarted fine and while sitting there idling i got a message on the dic that said service traction control then got the reduced power message. car was sitting there idling fine with the check engine light lit but had no throttle response. i shut it off and checked for codes. then i disconnected the battery for 10 minutes, cleaned the terminals, hooked it back up. now the dic flickers, the guages go berzerk, fuel pump relay in the fuse box buzzes and i can hear things turning on and off rapidly, and the car will not start. just clicks when i turn the key. i drug out the battery / load tester and the battery checks out ok. it is an 8 month old optima red top. thgen, just for kicks i put in a new battery and the same thing happenned. wtf happened to my car. it's a bone stock 99 A4 with 14,600 miles and absolutely NO mods. could this possibly be an ignition problem?? ground lug on the starter??

passenger footwell is dry. thanks for the reminder, i forgot about that. went out today turned the key to the on position (with a new battery). same thing happened again. did it 6 times and guages bouncing around, dic flickering, funny noises coming from inside the doors, etc.. every time i turned the key to the on position. on the 7th time i put the key in everything acted normal and the car started right up and idled fine. did that 4 times and it started every time. on the 5th time i put the key in it acted up again. did that 5 times and on the 6th time it acted totally normal and fired right up. would spraying contact cleaner into the key slot hurt anything in there?

i'll check both doors today. thanks. it certainly cant hurt, but i'm really thinking its the ignition. i found bill curlee's description of how to repair the ignition switch. i need to remove mine also and i'm not sure of the order in which to remove the dash panels. does the plate directly under the steering wheel come off first?

I think you should also recheck your battery connections, considering it started doing it immediately after you unhooked the battery. Just sounds like it could be a simple bad connection

Check and clean all the ground terminal blocks. See Bill Curlee's post for locations. Start with the ones in the engine compartment on the rails near the radiator and hinge for the hood.

i checked the accordians in the doors and the wiring looked fine. i pulled them off of the door side. the car side didn't want to come out. anyone know which side the wires usually rub through on? i also pulled the ignition and found 2 sets of burnt contacts.

Now I see why such an interest in my thread. Sounds like my symptoms are slightly different, though.
I've been through the door wire issue once before and used liquid electrical tape to cover the exposed wires. What spurred my interest in that was the driver's button panel stopped working.
If I were you, I would check and clean all the grounds:

Problems like we're having are so frustrating!!!!

saw, i did the grounds last weekend. all were clean and dry but i did them anyway. i'm hoping to have the switch back in tomorrow. i'll let you know how it turns out. what i would like to know though is this. what side of the rubber door accordian do you pop out to check that wiring bundle? i popped out the door side but was unable to pop out the side that mates to the car.

See posts 315 and 316 on page 16. There's a good picture of the accordion boot removed,
