RS4 front camber/alignment issues

[smg]

Hi folks,

Just bought an RS4 2021 with 37k km. It's my first Audi.
Brought it to the dealer for a general inspection, just in case.
Asked to check how's the alignment as well and it was a bit off.
They corrected most of it but the front camber, that they said can't be corrected/there's no adjustment.

My question is, how bad is that front camber difference?
Should I be worried?
I guess the only way to try to fix it would be to disassemble the entire front suspension and look if something is wrong/bent/worn?
Or maybe a sub-frame "readjust" would even out the difference?

Thank you!

the car will still be under warranty take it back to Audi with your findings
and if you've just bought it and your not happy send it back

Actually the dealer I mentioned was Audi, the alignment was done there.
And they said those camber values were not a problem... but reading some stuff on the internet, it seems it's not good to have more than half degree difference between sides.
That's why I got worried that something is not right and why Audi would just say "it's fine".

I've had a look in the Audi running gear, axles and steering documentation and in that they say the front camber cannot be adjusted but it can to quote them 'be centralised' so that both sides have the same camber within acceptable limits.
I have attached pages from said document for the 2MC suspension setup (from my build label) which is the setup on my 2018 car, I am assuming Audi haven't changed it since.

This may give you some ammunition when you back and see them. It sounds to me like they couldn't bothered to do the front end fully.

I also found a print out from someone elses alignment, which you will note is a 2MC from 2015

Hi Jools, wow nice, this will be definitely helpful

I'll send to them and let's see.

Thank you!

Not a problem, looking at your read out shifting the subframe doesn't look like it will help you, because if you slide it further right while decreasing the right hand camber you will go to nearly zero on the left.

Why would the front end be out of adjustment, I'm trying to think of reasons
Next, stupid questions
1. Do you have any previous history on the car?
2. Did you buy it from an Audi franchise or somewhere else?
3. Do either of the front wheel rims / bodywork / paint finish look refurbished, has someome clipped a curb damaged a wheel and bent the suspension?
4. Are there any telltale scuff / scrape marks on the lower suspsension arms, underbody trims?
5. Was it just built on a Friday afternoon and left the factory that way?

If Audi insist it's OK, tell them if it starts eating front tyres unevenly on the front end you'll be back.

hmm but in this case the subframe needs to be shifted to the left no? then we take some of that right camber (-1°47') and increase on the left that's missing a bit?

1. not much
2. somewhere else
3. that part is the one I'm trying to understand more... wheels are perfect, body and paint also but they found some scratches on the left lower arm, so it might have hit a pothole or so:

5. I don't think so

Yeah, the only thing I worry is because the difference is big right, so it's out of the "maximum permissible" and that bothers me
I also read that more than 0.5 degree difference will/can make it pull to the sides.

Thanks!

OK, just an update to this (was waiting almost a month for a spot).

They finally fixed it by doing the subframe shifting:



Seem much better now

Thank you all!

Great result, I'm glad it all worked out for you.
