strange how it's just a 500 thing.. not heard of it in the panda or punto..

and the fact it doesn't alter in 100K miles also says it's "just a characteristic.." = NVH

My panda twinair defiantly likes to moo in reverse but I think that there are not so many panda twinairs out there they are more of a budget run around great car and great engine though.

It's fairly common and reported on here a fair few times if you have a search, no real diagnosis I don't think but doesn't seem to cause any real issues either, my ta 500 did it once or twice but not in ages

My 500 twinair has mooed from new. Still does after nearly 6 years and 43000 miles. No gearbox problems. I quickly got used to it and accept it as a characteristic.

My wife's TA also does it as well.........we had a test drive before we brought it and it was fine, the groaning noise then started a couple of days after buying the car, doesn't seem to do it every day and doesn't effect anything, just there sometimes when you use reverse.

The only other thing we have noticed with the TA is that when you change from 4th to 5th gear the distance between 3rd and 5th gear slot is minimal, you don't have to push the gear stick far to the right to get it into 5th gear....hope that makes sense? just hope its not a selector fork

Car drives perfect and even the Mrs is getting used to the purring noise the engine makes

Hi thanks for the great advice but one of the problems I have is that I still have two years finance left to pay on my panda I have thought about getting a settlement figure and trading it elsewhere but who would accept the car making that groaning noise I know that I wouldn't have brought it if made that noise on the test drive. I am expecting a call from fiat tomorrow who knows what they will say this time but I am sure that if they log this issue and I have any problems in the following two years that I will have a battle on my hands in fact in my view that groaning noise is unacceptable in any modern vehicle and there seams to be many people who same issue on newer and on lower mileage fiats. The mechanic called it a mooing noise btw

Re your dilemma - from what I understand, webuyanycar will also offer you a price for your car even if there is still outstanding finance to pay off. I believe you just have to pay the difference before they agree to purchase the car. See this link:

Appreciate you may not want to go down that road, but it is an option. As for the groan, unless there is something specifically wrong with your car and it is a "feature" of the engine, I don't see how you would be trying to pull the wool over anyone's eyes. I believe WBAC would only have a concern if your car has a legitimate fault that you have tried to cover up.

Hi Ya'll spoke to my fiat dealership today and they want me to bring my panda TA back in so there tech wiz team can checkout the reverse noise' so after the second clutch change the latter being an upgraded new part well that's what they say they have done they cant figure out why the car still makes the mooo noise so it shouldn't then ?
But now on my way home from work I popped in to another fiat dealership in London and asked the guy at service desk if they know why my panda TA would be making this mooo noise in reverse the guy then checks with the mechanics and guess what they all said its the clutch and it needs to be changed its a common fault I take it then. It sounds like a lot of fuss over a noise in reverse and occasionally in second gear but I wouldn't have brought the car if it was making this terrible noise ARGH !

Surely this can not be a gearbox oil issue. Too much, too little, too thick, too thin. Sometimes the simple solution gets ignored but then greater minds than mine have looked at this issue. You honestly have my sympathies.

you're on your 2nd clutch in a short period of ownership , and the noise is still there.

and yours is a PANDA -in a 500 thread..

as I said - I've never heard of this in the Punto,
but they are all 6-speed - maybe that's the issue /difference.

reminds me of when all the Ducato motorhomes chattered in reverse until they changed the reverse gear ratio's

hi there doesn't seem to be any forums covering the fiat panda twinair with the reverse groan so fiat 500 twinair threads it is. same engine same gearbox and clutch with same groan noise that's my thinking I just don't think that its acceptable I just hope fiat can figure it out. the gearbox oil is something I will mention to the service department thanks.
My clutch has always functioned ok it is fiat that have fitted two new clutches trying to cure the reverse noise so who knows what happens next.

Our 2011 500TA groans a lot ................. but only when the clutch is slipping.
Reverse some distance with the clutch pedal up and engaged, it runs quietly. Drive backwards, don't slip the clutch.

This means that it's the CLUTCH that makes the noise.

Regards,
Mick.

There's lots of threads where we discuss faults common to the Panda & 500; there's more 500's on the road in the UK than Pandas, so this is probably the best home for your story. You're most welcome to continue the discussion here.

that's a good idea I will give the that a try I will take my foot completely off the pedal like you say it should show if its clutch related cheers.

Yes, slipping the clutch when parking etc makes the groan.

We have a long drive - 75yds - (nothing posh, we're in a very rural area and away off the lane) and I often reverse all the way up it with the clutch fully up.

The groan starts when I slip, but after releasing the pedal, the groan goes.

The manual for my Twinair says this about waiting 2 seconds once stopped before engaging reverse:


IMPORTANT The car can only be put


into reverse gear when it has stopped


moving completely. With the engine


running, wait for at least 2 seconds


with the clutch pedal fully depressed


before engaging reverse to prevent


damage to the gears and grating.

Whilst ours is not a twin air I always select either 2nd or 4th before reverse, do this and it will never crunch(leave foot on clutch), a trick I found with my early Accords

Reverse gear is straight cut and without syncromesh. So if you engage reverse gear before the input shaft stops spinning, you'll get a (basically harmless) crunch. In first gear the synchronisers stop the input shaft as you select the gear so no crunch.

Every car I've ever owned makes noise if you reverse at more than walking speed roughly. You'll often hear it in carparks and the like too. That's straight cut gears just doing their thing - generally, you shouldn't be reversing fast enough for it to be an issue. I've got a vintage pick up that's straight cut for every gear, big time whine in every gear but the direct 4th. It's lasted 65 years this way.

Why it would happen in 2nd I don't know though.

as would most car manuals I suspect,

the 2 seconds it to stop the internals rotating , before trying to select reverse gear.. ever noticed people grinding into reverse in car parks..

Yes, it's a good dodge if you have a slightly sticky clutch plate as it stops the input shaft rather than it carrying on rotating with the flywheel.

If you sit there at tickover in neutral, then select reverse quickly, you can get a knock or crunch. It's quite normal and caused by inertia. By selecting a forward gear (synchromesh) it stops the gearbox completely.

Another way, it to push the clutch pedal all the way in and dwell a pause of two marching paces before selecting reverse.

We have a long drive, and I reverse up it with the clutch fully engaged. Also, as we have many narrow lanes here, it's quite frequent that you may have to reverse a few hundred yards. Slipping the clutch over those distances is just plain wrong.

Regards,
Mick.

Well, I prefer the first, since I can't keep the clutch pedal floored while making 2 marching paces.
