I get the same thing...sounds like a cross between a fart and a cow mooing...I think its something to do with the fuel pump cos it usually happens to mine when the fuel is on the low side...it has done it for ages with no other problems arising from it.... dam embarrassing if you pull up where there are people around.. turn the car off and watch the reaction as the car lets out what sounds like a big pizza fart!.....that being said....I did notice my attessa fluid level was on the min marker recently.I haven't topped it up cos I forgot if it took power steering fluid or auto tranny fluid (please inform me)

Umm, don't you just use ATF fluid in the power steering resivior?

Only if it is a tiptronic! Otherwise you steering wheel will want to shift up all the time... I hate that...

(don't listen to me)

Could it be the Air con? Do you have it on when this happens?

Not sure how answering a question with another question is going to inform me...so what goes in the attesa reservoir?...

Pretty sure it's ATF (Auto Transmission Fluid). But if you do a search you'll find what's best. Mine did the same but it was because the rolling dimension of my front and rear tyres weren't the same. Once I fixed that and topped up the Attessa fluid all was good.

How much difference was there. Was it different size tyres or was the difference due to different tyre wear front/rear?

Can't remember what the % allowable difference was, but wear and tear wouldn't really cause it as it would be within the tolerance. When i bought the car, the dealer whacked on the 17" RS4S rims on it which had different profiles. Once i replaced the rears to match the rolling dimension of the front (235's vs 215's) and topped up the fluids, the shuddering stopped.

I had that same shuddering in my car. I was travelling on the highway and had 225/55r17's on the front and 225/50r17's on the rear.The "4WD" light started flashing. I changed to the same size all round the next day and it was all good

Sorry, I was having a bad day. I had just washed my brain and I couldn't do a thing with it :P

My point was, ATF is used in the power steering, auto trans and atessa.

Hi guys,

My S2 is making this 'fart' noise too when I turn it off; doesn't seem to be fuel related as I had about 1/3 of a tank; did anybody find the cause of this? Not tyres either 'cause I've got 4 new 205/55/16's on it on standard rims... just got back from compliance and all filters have been changed etc...

Check the Attessa reservoir. Make sure the level is above Min. Right hand side rear in the boot.

When this thread was first up, I checked my Attessa fluid and it was fine. I still think it has something to do with the fuel tank. Still happens now and then to mine.. but never when the tank is full..and only makes a noise when I turn the car off....something to do with the fuel pump..still ot sure... but it does not seem to do anything apart from make a noise.

cool thanks; will do! Has to be checked with engine running though doesn't it? That will take a few days lol... if it's gotten air in the system enough to cause a 'fart' will it need bleeding?

I've found that the levels have to be chacked with the car running too. Slightly above the MAX line is good. With mine, if it's below the MAX line it'll still occasioanlly "groan" when i turn the engine off.

      r34's love to squeal

      By Nizzy_R34 · Posted

      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.

      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.
