Hey guys

Over the last few days my S1 C34 RS4 has developed a vibration at idle, but only in drive or reverse gears. In park or neutral there is no vibration. The vibration can sometimes gets worse when the steering wheel is turned, and then it goes away at about 20kph or higher.

I think this started to happen after I got a wheel alignment, so im thinking there might be something that has been left a bit loose?

I havent been able to look under the car yet, so I dont know if theres anything touching where it shouldnt be, or anything like that.

Any suggestions about what to look for would be great :)

Are you sure it's not the idle speed dropping too low when the car is under load?

Strange that you only started noticing it after a wheel alignment, because it shouldn't have anything to do with that. But maybe you're right, and maybe because something has been left loose in the suspension, it's become more noticeable.

Took another look today, and the vibrating does seem to be related to the drop in revs caused by drive or reverse. It seems to be a bit intermittent, i.e happens on some days then not on others.

Do you reckon this sound like something to be worried about, or just something thats normal for a 13 year old car thats done over 130k km's?

i wouldnt be crossing a trans service off the list of things to do btw mate :(

Yeah, I have been meaning to have a trans service done, seeings as I'm not sure when the last one was done before I bought the car.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
