Default Help with F55

Hi All. 2009 base with F55. 60k miles but new to me.

I'm not feeling any difference between Tour and Sport mode. I read an older thread that said sometimes the dealer forgot to remove the shipping spacers from the shocks, which could cause just such a problem.

My question is, where on the shocks do I look for the spacers? Hidden by the dust boot? At the very top? I know they originally had yellow tags on them, but after 60k miles I doubt they would still be there (or still be yellow and visible)

If not the spacers, any idea what else may be going on? A fuse perhaps? (one can hope)

Any help or ideas would be appreciated.

Chances are that what you're doing (the driving conditions) when you switch between modes would produce the same result either way.

Try this. Find a fairly smooth road or large empty lot and at 20 MPH quickly/violently turn the wheel left and right several times in quick succession. Not lock to lock, but without changing your grip. Then repeat in the other mode. If you don't feel a difference, you might have a problem. However, if there is an electrical problem it would have created the DIC message "Service Ride Control".
It's also possible a previous owner removed the system, so check to verify an electrical connector is on the top of each shock.

Thanks! I'll try that.

Now from what I've read, the difference should also be quite pronounced on rough roads (and we've got some prime examples around here). It rides pretty rough on those roads, regardless of switch setting, which is the exact symptom quoted when the shipping spacers are left in.

I verified that there are electrical connections on the top of each shock.

It was hard for me to tell the difference at first. Once you drive it a lot you will be able to tell a difference. Tour mode "floats" more over bumps. Sport mode tightens up and you feel the bump more. It's not as drastic as everyone has in there head it will be. But going around corners fast you'll be able to tell from body roll and grip.

I hadn't heard of the HOX method before, but it sounds/seems more reasonable under a controlled area/situation than trying to duplicate exact speed on a road of bumps.

You COULD do it if you were willing to go out at 6am on Sunday, or something like that. Then, you could drive over that bumpy road at say, 20 mph in sport, turn around and go back to where you started, turn again and come back the same way as the first time in touring. That would be a good method if you can pull it off with no traffic around.

From what I've read on here tho, most C6 F55 cars do not feel all that different in either mode. Could be wrong tho.....

Just remember that F55 is not like having standard adjustable shocks - passive elements that are simply "harder or softer" even if the car is parked. With F55 you are changing how the car *reacts* in real-time to bumps, curves, braking, etc., so you won't feel a difference until you do things that let you measure the difference in car's *reaction* to the same circumstances.

Thanks all. I appreciate the feedback.

Let's, for the moment, assume there really is a problem. Can anyone chime in on my question about the shipping spacers?

It's my understanding that they quit using those spacers a few years ago precisely because of the issue of dealers leaving them in. My verdict = "highly doubtful."

Noted. The threads I've read about it are pretty old, so that's entirely possible.

In any event, I did find the procedure for removing them so I suppose it won't hurt to check. To anyone else who may be wondering, the spacers were located beneath the corrugated shock cover. The procedure is to remove the wheel, letting the suspension drop down, and then compressing the cover upwards to expose the spacer.

I'll give that a shot this weekend.

it would ride like hell and look like a 4x4 if the spacers were in. you would KNOW this... Get the car up in the air, they're probably fine. having said that, when i purchased my '08 F55 car with 93k on it all 4 were leaking BADLY. Two were completely broken (stuck when pressed in once i removed them) it was the driver's rear and passenger front.

Installed BRAND new ones and wow. what a difference. Just be prepared because they are expensive lol.. I still think they're worth every penny after riding in numerous C6's without them. not even a remote comparison.. good luck
