Mr_RS4 Posted March 15, 2007 Share Posted March 15, 2007 so i hear a ticking sound form my ECU under boostwhy is it doing this? Ive never had an ECU growl at me lol You sure its not your engine pinging at you under boost , sounds a lot more logical than an ecu making noises. I can't even begin to think how an ecu could make any noise?

AlexCim Posted March 15, 2007 Share Posted March 15, 2007 Try turning the climate control off and see if it still does the noise. Over time the fan can become dirty and therefore unbalanced, this will then cause it to "tap" against its housing. Happend to me about a year ago.

yokotas13 Posted March 15, 2007 Author Share Posted March 15, 2007 with no AC on, no radio on its a ticking sound. i had a friend ID where it was comming from while he was in the car one day.

Mr_RS4 Posted March 15, 2007 Share Posted March 15, 2007 (edited) with no AC on, no radio onits a ticking sound. i had a friend ID where it was comming from while he was in the car one day. I dont notice a loss of power at all, its just annoying Yeah detonation (pinging) is a ticking sound (well at least thats how it sounds to me), espically if you say its only doing it under boost. But I mean I could be wrong, it is a car after all and a ticking noise could be anything. But I seriously doubt its the ecu! Anyone else?

Stinky Rooster Posted March 16, 2007 Share Posted March 16, 2007 CHECK YOUR FRONT DRIVESHAFT UNI'S!!!!!!!!! Seriously dude, mine did this not long after I bought it, I thought the tapping sound was coming from behind the dash, but the intermittent nature of the noise made it really hard to track. Apparently the front shaft should have next to no play in it so if it has freeplay (as you expect a rear shaft to have) then you need new unijoints.

AlexCim Posted March 17, 2007 Share Posted March 17, 2007 pinging is not really a ticking noise. pinging is more of a "two twenty cent pieces being shaken in a closed hand" kind of a sound.

chrissso Posted March 17, 2007 Share Posted March 17, 2007 Hey, did you get this resolved? In another thread, you have lost spark - maybe, i think that problem isn't resolved either.. Is it possible that you had a short in the ecu and the current isn't making it to the spark plug? Try taking the top cover off the ecu and see if you can see sparks when you rev if. Just a suggestion. Link to comment https://www.sau.com.au/forums/topic/160575-my-ecu-is-growling-at-me/#findComment-2986353 Share on other sites More sharing options...
