2003 Audi TT Quattro - sudden stop and no drive :(

[Krhuangbin]

Wonder what happened here - just a short while ago, pulling out of a junction and there was a bit of a muted "thud" in first, then suddenly no drive.

Pushed to side of road into a parking bay, and starts and runs fine - but gearbox does not engage anything. No noise idling in neutral, however when into 1st and 2nd there is a faint rough knocking rumble from under the gearstick in the 'box.

Between 3rd and 6th and with some revs, produces a noisy whistly whine, rising and falling with the revs from around the gearbox area.

Absolutely no drive whatsoever, not even a hint of engine to wheels transfer. I don't think the clutch was slipping at all to be honest.

However I have noticed an in-gear slight shaking/rumble recently at motorway speeds after a while when decelerating. I'm wondering if its drive shaft related?! Clutch cable? Not sure. Cant see any fluid under the car anywhere.

Any help gratefully received

Manual gearbox?

What does the clutch pedal feel like?

Can you move between gears without the clutch in?

Thanks Craigy. Yep Manual. Clutch feels completely normal - pressure and return as usual. Gears can be selected as usual too. Just zero drive /bite, and the slight rumbling/grinding when throttle applied in 1st and 2nd, and the same with added whistling rotating whiny sound 3rd to 6th with throttle

Edit to add - I’m not with the car at the moment and didn’t try to move into gears with no clutch. However I don’t think it did, it felt normal

All else being normal I'd suspect the flywheel or clutch has gone.

One loud thump would potentially be the dual mass flywheel becoming two separate parts and springs or bolts rattling about in the transmission case.
Either that or some splines no longer engage at all.

Oh dear - would render it scrap really

Probably worth sticking it on a ramp to check, but I'd expect yes. Parts car.

[GreenV8S]

Rumbling off load suggests a major mechanical problem such as a damaged bearing, and total drive failure suggests this has now failed catastrophically and wiped out something else. Given the age of the car it hardly seems worth spending money investigating it, but it might be worth sticking it on ramps to see if you can confirm the problem is within the gearbox. You can probably judge for yourself whether the car is worth enough to justify the cost of a new trans.

Definitely not worth a new trans - think it's days are at an end.

The selector forks are a known weak point in the gearbox - they’re riveted together and that can fail meaning no gears will actually select. It could be that, or a number of things along the drive line to clutch splines or DMF failure - your symptoms suggest it’s most likely those (or a broken diff).

Second hand gearbox is usually best bet - though the fix isn’t meant to be too hard (tackled on Wheeler Dealers years back).

I don't know where you are, but if you're near Brackley these guys can fix it:

Only you will know the number the car is worth to you.

Get the spanner’s out and fix it up?

More or less sounds like OP has made up his mind. His car, his choice.

Already replaced the car with another run-around. I would like to see if it's fixable and flog it on, seeing as it's just had a brand new MOT etc, but the car is worth £1500 tops on a very good day, mine more like £800-1000 given its condition/mileage... and anything gearbox/clutch related is well beyond my very limited skills.. and the car is outside on the street, in the rain, immobile. Just more hassle than it's worth sadly

It it has a working dashboard and coils it's probably worth something in parts to someone else with a TT that age.

The cats, if still fitted, are worth quite a lot of money and can be the profit in breaking. Wheels, cats, BAM engines, interiors if in good nick, some body panels like wings, and more. If you can’t break it yourself, offer it up on one of the TT Facebook groups or the forum - but the dealers who buy them to break only want to pay £500-£600 for them so it’s worth pushing for more.

Thanks for this (sorry for late reply!)

Any recommendations for breakers SW London/Surrey who'd pick an otherwise solid TT up for £600?

[bangerhoarder]

I know there’s a bloke in Enfield that breaks them - not too far? He’s on the TT for sale Facebook group.
