    Must admit i misunderstood the question too :).

    Well, if helpful and as you already probably understood, i've jacked my car up multiple times with a trolley jack on the seams and never had any issue and i'm about to do it again this saturday to stick my summer setup back on.

    How's the underseal holding up on your jacking points? Although I haven't ever jacked mine yet, the underseal was split on the jacking point (I guess from the PDI). I'm not sure if that's going to be an issue or not...

    Not quite sure why people would mistrust the manual, or not think that the people who made the car would know where it's safe to jack up the car?

    For me, I'd obviously be perfectly happy to jack anything how the manual says with the factory jack. With my 2002 Octavia, the factory jack didn't press on the seam, so when I used my trolley jack I didn't jack the seam but instead used a completely different point on the underside.

    On the 8V the factory jack seems to press on the seam, and there's no other place that's obvious for a trolley jack, so I'm thinking I'll trolley jack it on the seam when it comes to it. But I'm not 100% happy with that, as I know older designs could fold the seam if you did that, even at the proper jacking point, when using a trolley jack rather than the factory jack.

    A jacking point is a jacking point - doesn't make much of a difference if you use the jack that comes with the car or not. It's not like they use those jacks at Audi when they service your car...

    Yes, but on older designs the jack that came with the car pushed on a completely different bit of metal than a trolley jack used at the same place. Hence various posts on various forums about cutting slots in ice hockey pucks to use as a jacking pad.

    Some of the main dealer lifts I've seen have a huge pad which covers the jacking point plus quite a bit either side of it, spreading the load. Also they lift all 4 corners at once, perfectly vertically.

    A trolley jack on one corner will apply some sideways load, and isn't a huge area. Hence people in the past getting their jacking points bent by trolley jacks, especially at tyre places.

    I'm hoping the 8V has stronger seams so will be safe, but there's still a slight concern at the back of my mind.

    Interesting. I'll have to keep an eye on mine... I wonder why it's got damaged. I'd be interested if anyone else has split underseal on their jacking points.

    I used to place my jacks in the centre of the subframe that goes between the two lower wishbone bush mounts. I've not really looked under my car to see if that is available though, perhaps somebody who has had their car on a car lift could have seen if it is possible...

    Yes.
    On my 8P S3, a trolley jack was used on the seam exactly where the jacking point is. The seam bent, and split the underseal. Both sides.

    The seam has now been straightened, and underseal repaired by myself.

    I now have an ice hockey puck (hard vulcanised rubber) with a slot cut in it I carry in the car, and lend to the tyre fitting places when they jack my car up, if they don't already have something similar/suitable.

    I will now be extremely wary of using a trolley jack without any additional protection, on a jacking point designed for a scissor jack.


    edit: Incidently when the 8P is lifted with a 4 point car lift at the dealership - this is lifted at a completely different point - not at the seams. You need Jack Pads - and even with these Jack Pads, they are really supposed to be used only with a 4 point lift.

    As said previously, i also use a rubber hockey puck with a slit cut in it, i believe that's what protects my seams.

    On my 8V, the metal is fine and nothing's bent. It's just the underseal that is damaged. Your experience is exactly what I've been trying to explain could happen with the older designs though.

    Trouble is I'm not sure that works as well with the 8V. On older cars, the factory jack pressed on a reinforced area just inboard of the seam, and that's the bit the hockey puck presses on too (the point of the slot in it is so that it can clear the vertical seam completely).

    On the 8V the factory jack seems to lift on the seam, so the reinforced area inboard of the seam isn't there in the same way. Also, most of the rest on the underside is covered in plastic, so the beams I used to use to jack my Octavia either aren't there or are covered.

    If your underseal is damaged, then your 12 year anti corrosion warranty won't be valid........

    Best get that repaired asap.

    I'm puzzled as to why it's happened, and whether Audi are expecting the underseal to get damaged on the jacking point itself. Mine's never been jacked since I collected it, so the PDI would have been the only time it was jacked. From marks in the protective wax, they used a big pad to jack it, which covered the whole jacking point plus overlapped beyond it, so it doesn't look damaged by a trolley jack or anything. It's just strange that the underseal had split apart where the weight of the car has gone through it on the jacking point.

    Thanks for your replies AJB, im glad I wasnt the only one showing concern. Appreciate you replying and explaining. after having several VAG cars it is just completely alien to use the seam :) for the last 10 years all the others were designed to avoid it :)

    and as for the comments above, i do read and have read the manual, it was a genuine question as it is a very different design to previous thats all. better safe than sorry

    I've just spent the day sealing the wheels and coating the underside and suspension of my day old 8v with anti corrosion fluid. I had to jack the car to get the wheels off obviously... I didn't want to use the car jack so I used my trolley Jack (with a rubber pad) and I used the jacking points fitted to the chassis members designed for four post lift arms... At the rear it is a rectangular solid plastic/rubber block forward and inboard of the sill j/point and at the front it is a round plastic/rubber protrusion just behind the wheel arch and rear wishbone mount. I used these with no problem and no sign of any deformation and definitely no damage to the underseal. Mine is an S line (with the sill extensions...) so there was no way I could my Jack on the sill jacking points.

    Interesting. I'm pretty sure I don't have those blocks-I spent a while looking and couldn't see any obvious points to jack from.

    I wonder if they only fit those to cars with sill extensions where a 2 or 4 post lift would be able to use the sill jacking points...

    Maybe they could be retro fitted to non-SLine models...

    I'm almost certain I don't have those either. Just seems to be a sea of black plastic under the chassis with no real solid places to jack it other than the thicker sill points.

    Does anyone know the best place to put axle stands? I'm hoping to paint my rusty wheel hubs over the weekend.

    Cheers

    I don't know if it would help but I could try and take pics of where these blocks are mounted tomorrow. I'm sure the chassis parts that they are bolted to will be the same as non S line cars so with the appropriate block/pad you could use a trolley jack on them...

    Yes please! That'd be really interesting to see if you get a chance. Not least just to know which areas are strong enough to jack, but also hopefully to be able to fit the blocks to mine.

    I'll do my best!! Paintwork sealing tomorrow. Must say I'm glad I did the corrosion protection on day 2 of ownership and not left it any longer - the hub centres are quite rusty already and it was only build 3 weeks ago! Wheels also transformed with some sealant...

    OEM Jack Pads.

    They fit in the 4 holes in the monocoque where the car is cradled around the factory during production

    The dealer inserts these when they have to lift the car using a 4 point lift.

    Really only designed to be used for a 4 point lift (to distribute the load) rather than a trolley jack. But better than bending the seam.

    Similar to the ones on the front of mine but the ones at the rear are rectangular blocks and fixed to the chassis rails.

    Sounds like they have brought out a new rectangular jack pad for the MQB for the rear lift points.

    This pic from a Golf Mk7 without the jack pad inserted.

    Yep - the left hand bung (which is in the slight depression) is where my rectangular jack pad is.

    Thanks for the picture. My 8V (Sport trim) looks exactly like that Mk7 Golf picture at the back, so hopefully the block could be attached easily. At the front everything seems to be covered in plastic though... I can't really see where the round block would go. Maybe there's a different covering panel with a hole it in? How does the S-Line front jacking pad fit in with the black plastic panels on the underside?

    Is there a removable plastic panel? This is how the 8P was.

    I couldn't get far enough underneath to get a close look because it was only on the trolley jack and I don't trust them, but my next door neighbour has a proper ramp lift and I'm gonna get it lifted up next week so I can finish coating the underside in ACF50 - I'll have a better look then and if I remember I'll get some pics.

    Seems damage to underseal is common on new vag cars with seam lift. Have heard several people saying underseal splits
