It has been the most reliable car I have ever owned, doing over 12,000 miles with little more than a hiccup but today it let me down and in a big way.

I was going around a mini roundabout, not particularly quickly but the traction control did cut in (it was slipperly). The next thing I know, the car lunged about made a few loud clonks which I felt through the car. Straight away I though "DIFF" so whipped it into neutral and rolled down the hill and parked up.

There was a significant amount of diff/gear oil leaking out when the AA recovered it on their flat bed lorry so I know something has popped. I'm quite confident it is not the engine or gearbox as the engine ran fine (we had to run it for the P/S to get it back in my driveway) and the car kept clunking when we pushed it into the driveway (when under full lock) and it was in nutural so the gear box could not be to blame.

Annoyingly the car is about a month outside the dealer warranty. Luckily alfa's have a reputation for being unreliable so I happily took out an extended warranty when I brought it! I'm quite confident it will cover this problem, the only exclusions are the clutch and brakes mechanically and auxillary electrics.

It is just a shame that it has let me down. I have been praising it for the last few weeks on how well it has done. That is a big milleage for such a short period of time.

If anyone can advise of likly causes please let me know. I am responsible for some of the diagnosis costs so the less time spent there, the better :)

Hmmm that's a strange one could be CV joint maybe?? I'm not 100% sure I'm right but if you think the box is ok it's the only other thing I could think of.

I had a driveshaft let go on my old twinny, sounds like the same as what happened to you, it'd select gear fine but as soon as you lifte off the clutch you got knocky grindy noises.

I'm starting to think that now although there was alot of oil.

I have had this clunking before on full lock. It happened once and was fine. I just put it down to nothing. Basically for every rotation of the front wheels it makes a loud clunk and puts on a bit of resistance.

I was only doing about 10mph though and as soon as it happens dipped the clutch and took it out of gear so may have saved it from serious harm. I'm going to try and get my warranty company to let me take it to Monza Sport as they are pretty good.

Silvervalver: Its probably going to be the diff. We all know it's a common fault on the car, and we all um and ah over the symptoms when it happens (search for Nicky's thread on diff failure in his 156 V6), but in the end its always the diff. Hopefully your gearbox is OK, you have warranty on your side (hopefully), so all in all it might not be a major problem for you, and you can replace it with the Q2.



Everyone Else: Again, this is just another example to everyone with a GTA on here, especially 147s it seems, if you do not have a warranty, YOU CANNOT RELY ON THE STANDARD DIFF. Not changing the diff for the Q2 is about as dangerous as not changing your cambelt. Bacon's went at 22k or so, it is a fact that these just aren't lasting like they should, and they can take out gearboxs with repairs in the thousands (last one was £2200, luckily the gearbox could be rebuilt by AutoLusso at not too much cost).

Best of luck with it SV. :)

It'll be reet ;) wonder how much a warranty would be on my motor, if it's within a £100 of the Q2 I might as well just have it done...

Nowhere local to me does it though :(

my warranty was £400 for 24 months when i brought the car from a dealer in wakefield. I have read the booklet cover to cover now and I am quite happy they have no reason not to pay up. It was checked by them when I brought it, serviced at the correct intervals by a main dealer (and inbetween 1/2 services by a local garage too).

Typically I had planned on getting a Q2 but lost my job a few months ago so just keeping the car was a stress on the finances :(

For reference my car is on 30,800 miles with farsh.
Most of my miles (12k this year) were motorway and the previous owner put similar miles on it in a short period of time so I assume that was motorway too.

It did apear to happen when the TC cut in and was nearly on full lock.

Actually saying that, I think thats what most other people say, better stay away from full lock then...

:(

Hope the warranty people pay up mate :)

Take the missus to London for a coupe of days, and get it booked in at AutoLusso while your there, club members get it all in for £480. Excellent time to get any suspension arms changed as well as it all has to be unbolted.

Bloody hell, if I stayed away from full lock I'd be doing three point turns everytime I wanted to go round a corner in the Alfa! Turning circle is a joke :lol:


Hope everything works out OK Silvervalver. If you need to get it repaired on the cheap you could always pick yourself up a gearbox from a 156 2.5 V6 and bang that in.

I hope so too. Like I said though. I have all the paperwork on my side. I can't see how they can get out of it. They list these issues under the items covered under warranty after all.

It is just annoying more than anything. I brought a mint GTA, and since buying it, it has been wrecked. Stone chips, hole in the grill (from a huge stone i guess) and a dent a scratch to the rear wing. I just want to get it all sorted and back to A-1 condition again.

The differential was about £500 fitted at most garages when I was enquring so if you have the money I sugest you get it done. Don't put it off like me :(

Wiser words have never been said :)

How do you go about fixing it then? Do the warranty company just fix it and give you it back, or do you have to get it assessed by them, and pay yourself, then claim the money back?

in the booklet it says you get it diagnosed and get the garage to call their claim line?

I am however going to call them first. The main thing for me is I want to have it done at a main dealer. I did havea problem when I first brought it and there was a mention of Nationwide auto centre whom I don't know and don't want to know. I like to use garages I know and have heard good things about. Nationwide sound a bit like a kwikfit type garage so I can't imagine their "fitters" being able to replace the diff on a 1.1 fiesta let alone a 3.2 V6

Yeah don't use somewhere like Nationwide, I'd cringe if I had to take my Mondeo there nevermind the Alfa..

However, some warranty companies cover labour, but only to a maximum of £X per hour. Meaning you have to pay the rest. So maybe an Alfa independent specialist might be better than using a main dealer.

SV, I think Nationwide are more tyre based, but I can't be sure. Check through your literature first and see if you can have a respected Alfa specialist look at it. The fact that you have gear oil on the deck suggests casing failure. This will likely be specifically excluded from your warranty. (I know because I was in the trade and delt with this sort of thing for customers regularly) However, an Alfa specialist will be able to explain that internal diff catastrophic failure caused casing failure. This really will make all the difference to your claim and prevent a lot of expense and legal wrangling.

Also, see if there is a betterment clause to have the Q2 fitted. Failing that, perhaps there is some manoevering space for customer service with the repairer.;)

What is known to happen is that at full lock and when TC kicks in it judders the the diff, poping the lefthand driveshaft, this slides out and bangs round, but is still in the casing, the bad bit is that the diff is no longer supported correctly and oscilates inside the casing till it explodes, if your lucky you can pop the driveshaft back into the diff and get it to a garage, but more often it's totaled. The Q2 diff actually is better because it kind of prevents(delays) the TC from activating and it's larger physical size means that the driveshafts don't actually pop as they are under less stretch at full lock.

Unfortunately it does sound completely like the diff. When mine went (20mph in a straight line on a flat road, for reference :rolleyes:) the RAC guy first suspected driveshaft, but it did indeed turn out to be the diff - one of the captive output pinions had sheared into lots of little pieces, gouging metal out of the diff housing as it let go, and spreading sizeable chunks of metal throughout my gearbox. End result was a full gearbox rebuild with the Q2, and although it's now sweet as a nut it was very stressful at the time and something of a financial burden (final price was just under a 4 figure sum :cry:)

Thing is there's absolutely no warning this is going to happen - the first you know about it is when your steering jerks as you turn the car and your wheels make a clunking noise, and by that point it's already very expensive. Mine went around 75,000 miles but as has been said above the mileage at which they go seems to vary wildly, some apparently as low as the 20,000s :eek:

Sorry to hear it's given up the ghost but now there's absolutely no excuse not to get the Q2, and when you get it back you'll fall in love with it on a whole new level :thumbs:

Had I not lost my job the car would have had the diff, quad exhaust and a re-map by now lol!

I spoke the warranty company. No hassle at all. they agreed it was better to go to Monza sport than nationwide as in the long run it will probably be cheaper in terms of labour (i doubt a tyre fitter can change a diff in the guide book indicated time). All affected bits will be covered (diff, driveshafts, gearbox, casings etc)

I will hopefully be able to get it over to them tomorrow and will get a final diagnosis and let you guys know.
