2016 SQ5 LCA different than regular Q5

[rich045]

So the front LCA’s on my 2016 sq5 are bad, I ordered what I thought was the correct ones along with the ball joints to find out that the ball joints were correct but the control arms weren’t.
From what I was told by the rep at fcp, the sq5 shares LCAs with 13-16 S6 and 13-17 S7.
So now what do we do? There is no aftermarket and it’s a dealer part only that’s about 400 per piece.
Does anyone have any solutions to this?
Does the regular Q5 ball joint fit the sq5 knuckle?
Part numbers 8K0407151G and 8K0407152G
The other ones without the G are incorrect.
Also whatever is cross referenced to B8/8.5 a4/s4/a5/s5/q5 is incorrect.

I don’t get why an S6 or S7 is even mentioned. Complete kits from Myele show same part #s for a Q5 3.0/ SQ5, while an S6/7 is a different part #. What did you exactly order?

The lower control arm. Check the part number I posted above. The lca for the sq5 is sq5 specific, does not coincide with a regular Q5.
I am also showing a picture to show how it doesn’t work.
Anyways looks like no one else has ran into this problem so I’ll just bite the bullet and buy these 800 dollar control arms.
Btw this is what shows on Audi parts search. Dealer also confirmed it.
Btw looks like the aftermarket has got it wrong.

That doesn’t make sense, a 3.0 q5 is an Sg5, with different, tune , exhaust , dampners/sorings, exhaust, and int/Ext bits. You should pm Mops. Because I’ve read a lot about the suspension and stuff, this is the first time I read of control arm differences.
So yea, I see what you are saying in the FCP part listings. ECS has the same kit listed Q5/Sq5, and seems to have more options as to single control arm pieces. What about just changing the bushings if it’s true that they are different? That’s what the dealer would do anyway. There is definitely something up with that specific part.

W/Air suspension seems the key there.

The B8 platform does not have an air suspension option which includes the Q5/SQ5.

Here are the lower control arms I purchased from FCP Euro for 2014 SQ5 which should be the same parts for your 2016. I went with Meyle because it comes with all new hardware/bolts. The Meyle LCA are based on 8K0407151F and 8K0407152F.

When I saw other websites, they list 8K0407151F and 8K0407151G as interchangeable.

I'm not sure why the control arm would be on the same platform as an S6 or S7 when the B8.5 SQ5 shares same platform as the Q5 and Macan of this gen. Now you got me thinking if I have the wrong ones. I will ask FCP as well. I have not installed the Meyle arms yet.

This is what the electronic catalog shows

Interestingly, the price in the EU is 180 EUR per piece, and there is also an after market

You have the wrong parts, 8K0407151F is not for SQ5

[blkmz3]

I sent an email to FCP indicating their parts listing and reference is incorrect. Seeing if they will accept a return.

The more I look at the other manufacturers like Lemforder and Meyle. They list the interchange part numbers for both F and G.

Meyle also has on their website

116 050 0225 which is on FCP matches to both F and G

Exactly, I’m saying that “air suspension” may be the issue. Since no USA models haveLooking at part# of the steering knuckle, they all relate. Can you get an aftermarket LCA locally for a 3.0 Q5 ? Bring the definite wrong one, compare at the counter.. don’t have to pay for it then if it’s wrong.

Yeah that might be the differentiator. S6 and S7 came with air suspension. The B8.5 SQ5 DID NOT.

Maybe OP can do a side by side comparison of the 8K0407151F vs. 8K0407151G. Measure with calipers and compare geometry. Audi Engineering would be able to confirm the revision differences.

I would take both to the dealer, see what they come up with. Honestly, if you took the car to the dealer, they would figure it out by pulling all the part numbers off the shelf., then grab the match. The internet is good, but sometimes face to face is better.

Proof that the same part is in the S6 model, otherwise the FN0 mark is for the S model




There is a difference, it would be easier for Audi if it were all the same part to replace, easier for logistics and parts procurement

Bruh, stop looking at parts diagrams. Correct me if I’m wrong here…
The part sent to you is listed at Audi for SQ5 & S6.
FCP sent you that part as appropriate for sq5 & S6.
The part doesn’t fit.
Complete upper & lower kits show same part number for q5 3.0 & SQ5.
Everyone typically does all of them at once so as not to return to the scene of this crime.
So all these years have gone by, and nobody mentions that the front lower is different and received the wrong part.
Idk buddy, phook the internet, I stand by my previous comment. Go to the dealer and compare, or make some phone calls and deal with some live people in person.
Gods luck, it’s frustrating, I would be annoyed with this. lol, that’s why I let my mechanic do everything now, let him figure it out.

[rich045]

Ok obviously you guys are over thinking this.
The ball joint is correct and the sleeve on the control arm is too narrow, which means the correct arm would have a sleeve that is bigger, may have some other differences.
I cross referenced the bushings and am just gonna pop the old control arm off, switch the ball joints and bushings and call it a day.
Yes it’s a different control arm, yes the ball joints are bigger. No it doesn’t matter if it has air or not. I check a few US online parts websites with my vin# and my local dealer parts department.
Why does the sq5 have a different control arm from the q5 with the 3.0t is beyond me but that’s what comes up. You don’t like it, well it’s my problem to deal with I guess and I am dealing with it by researching and asking questions.

The M14 TRW ball joints I have fits flush on the Meyle 1160500224HD control arms. I do see in your 1st pic that the ball joint you have is not sitting flush against the bushing. I don't think you ever confirmed the LCA you show in the 1st image is 8K0407151F or 8K0407151G. Which arm was too narrow?

[Smac770]

The front axle lower arms are the track arm (straight) and the guide link (curved). The "control arms" are the upper two, if we're using Audi's specific terminology.

The Q5 track arm and the SQ5 track arm only differ in the same manner as the A4/A5 vs S4/S5, the inner bushing. Both the Q5 and SQ5 use the same track arm ball joint, 4G0 407 689 C. The Q5/SQ5 use the same track arm and ball joint as the C7 A6/S6/A7/S7, with the 8K0...F for A/Q model and 8K0...G for S/SQ model, and the 4G0...C ball joint for all.

So whatever the part issue is in the opening post, it's not because of Q5 vs SQ5 track arm difference.
