today was a not so good day for the audi..first it started raining crazy...in nebraska..(driving to colorado) and i mean crazy rain so i going 65..and 3 semis pass me....just showering my car like i dunked it in a pool...so the cruise shuts off..and the kicks back on a few seconds later...so then..it does this again..so i take the cruise off..same problem what happens is the rpms just drop to below idle, i go to press the accelerator..no response..brakes..nothing..then it comes back on..so i pulled over looked it over knew it was the puter becasue my relays where going crazy..so i had it towed..and they where puzzled..so i had them check my puter..they dried it off and let the engie run to get warm..which helped..so 30 miles down the road it does this again...and i am now pulled over at a motel...perhaps i could get alittle advice? but i am thinking that i just need it to dry out..because the airfilter took on some water as well..just a little in the casing..

 

no CEL?

 

yea...dont have the code machine

 

I had something similar to your experience. I would have the cruise control on and the car would shudder and almost stall. The cruise would disengauge and the rpms would recover. Turned out to be a bad o2 sensor.

 

you think i can make it 500 miles to my destination and then replace it?
and how much dese one usualy run?

 

hey jest..i was also wondering if because the ECU was wet too that could result in a problem? if so just let it dry off?

 

so did u have like a minor hydro lock problem

 

i dont think so..i am almost certian that the ecu just got wet..and that it didnt like that..that was my diganosis..atleast but i am not to car savy..but like i said when the rpms start going crazy...it either dies..or regains..but while they are in "insane mode" neither the brake or accelerator work..which isnt good..and the relays make a crazy chatter..but i determinted it wasnt bad relays so thats how i guessed the ECU..but could the ECU just getting wet make my car that insane?

 

Its almost impossible for the ecu to get wet, it in a sealed case under the hood, thats opened to the inside of the car, is the ecu was wet, your drivers side footwell would probbaly be wet as well
