    it might be the engine/transmission moving too much in the mounts, or linkage adjustment, try changing gearbox oil too. worst case its syncromesh or a selector shaft going in the gearbox.

    The 6 speed gearboxes dont like to be rushed. Depends on what you define as quick gear changes. Like it has been mentioned before change the oil, check the gearbox mount to see if its tight. You can replace the gearbox mount aka dogbone with a harder one which will feel much better but be aware that you will feel more vibration through the car at idle.
    Does it still crunch when driving calmly?

    Thats exactly how I described the same problem, as if the clutch isnt engaging properly...

    Seeing as the parts are cheap I'm going to replace the slave cylinder and as a preventive measure I'm going to replace the clutch pedal and bushings which are prone to going as we've heard many times.

    I've had this for 2 years... Then recently my fuel pump started to die (made a weird recyprical rubbing sound at the rear underside of the car) and has been replaced. As a pleasant side effect **drum roll** the crunch from 2nd to 3rd has completely gone ! I guess the fuel supply was backing off more aggressively than designed due to the fuel pump's problems and hence the timing for the synchromesh was out somehow...

    The fuel issue never threw anything up in VAGCOM etc.

    My 1st to 2nd gear crunch just dissapeared one day. However not so long ago it developed a 2nd to 3rd gear crunch. I m going to get the dog bone mount installed by Jabba, see how that fairs. Reading this post though my car is still on the original clutch (50k) so they could be linked.

    How much is a fuel pump ?

    If I remember right, 150 with an hours labour....

    I used to find it was less crunchy after a servive too... Have had the linkages tweaked by Audi before which solved it for a couple of months...

    1st and 2nd gear in my S3 have been a little crunchy since I had it almost 2 years ago. 2nd is the worst, it sometimes goes into 2nd in 2 stages if that makes sense. The wife manages to crunch 1st a lot when changing down into 1st approaching a juntion etc.

    Is this a problem, is something about to fail, or is it normal? Can it be fixed?

    Dogbone mount helped me out a Little, I've got my gearbox oil just haven't changed it, I will hopefully this week and see if it helps with my crunching issues.

    Not too sure how good it is to crunch into 1st when approaching a junction, I wouldn't do that unless I was downshifting which I don't do down till 1st gear.

    I would advise not going into first while rolling. It's not that great for the syncro. I always prefer to slip the clutch a bit in second. A clutch change is a fair bit cheaper than a gearbox rebuild.

    I agree with the both of you.

    The wife is used to driving her Z3 which is much more forgiving on the gearbox/gear change than my S3.

    My question was more aimed at why second gear was being awkward.

    Mine use to do it when under stress but has cleared up these last few months and i've not touched it, oil level is fine and every thing is tight. Just a S3 thing by the look of it.

    I think he means dog bone mount. It is the engine stabilizer at bottom at the back. It controls how much th engine is allowed to rock forward and backward. The OE ones are fairly soft and can be uprated to stiffer ones. By using a stiffer one gearshifts can be more positive as the engine doesn't rock as much when coming off the throttle. The only downside is that you can sometime get more vibration in the cabin.

    I would say clutch is under so much pressure. Had a honda that did the same thing under hard accelleration. Eventually (after 6 months) Clutch went.

    Hi all, I have the same issue with mine S3, from second to third under hard acceleration is crunchy... it kills me
    I have changed the dogbone and the engine mounts as well with THS ones but the noise is still there.

    I have bought MOTUL performance gearbox oil and I will change it, I pray for the noise to go away....

    this issue is still on, living in almost every S3, TT or Cupra R...nobody has the right solution.
    I hope that there is not a syncromesh or worse...

    The wired thing is that when the engine is cold, or the gearbox oil is cold, no matter how hard I go from second to third there is no noise, no crunchy at all...and when the oil start to get high temperatures...the crunch appear! It might be related with the OIL? the EOM OIL is not performing well under high temperatures?

    any answer will be highly appreciated, even the topic died 2 years ago!

    if its crunching when up to temp its probably down to tired gearbox oil, as you say not performing 100% when hot

    i changed my gbox oil a while back, i used redline lightweight shockproof oil from opie oils, think the idea is that it is fairly viscous even at full working temps so sticks to the gears more providing a 'cushion'

    since changing mine no gear change issues, although as said above the 6spd box doesnt like to be slapped around, treat it with kind and it will do the same for you

    thanks for reply. I got 2 liters of MOTUL Gear Competition, I shall change it these days to see if works, hopefully it will...

    Although I drive last weekend to the mountains , multiple S curves, almost 100 km on "S" curves, pretty much hard acceleration and deceleration, smooth gear changes but rev'ing from 3000 rpm to 6000 rpm and back continuously, and suddenly the gear crunch stops, absolutely not even the smallest crunchy...dunno why!
    I drive to home and after 2 days the crunch comes back

    It could be the position of the gearbox? it is not settled right? I have changed the dogbone with a more rigid one...
    I cannot imagine, why it stops after racing driving on the mountains...and now it came back.

    I will change the Oil and I will handle the ****ty 6Sbox very gently.
    I love the car but the gearbox could be better

    Yeah would be interested to know if a change of gearbox oil makes any difference.

    Mine does it still.
    Had the car three years + now,
    In this time its had powerflex dogbone mount. New gear box oil... still here though

    I was now thinking either linkage or the sensor thingy that makes the car rev up slightly when you change gear??
    I did hear these can play up slightly,

    There seems to be a knack to it, if you grab the stick from lower down, it wont crunch in as bad, however its slightly awkward changeing gears like that, i might take it in under warrenty next month and see if i can get some bits changed,

    Same problem here since a couple of weeks. Already changed the gearbox oil and added syncromesh additive.
    Also mounted a Powerflex dogbone bush. Nothing helped.
