Hi everyone,

I have an issue with the steering column lock in my 2004 Cayenne S.

When I pull the key, i can clearly hear the lock engaging, however, I can still turn the steering wheel. While I turn the steering wheel, I can hear a constant clicking sound, just as if the "locking bolt" has not engaged properly.

I've tried searching for the issue, but couldn't find anything that resembles my problem. Every other topic I found seems to be about failing control modules that render the car undriveable, however I have no issues of that kind at all.

Any ideas how to fix this?

I've made a video of the issue:


Thanks!

 

I'm not an expert on thos one, but from what I've read, yours has failed, but in the unlocked state, so I'd leave it as is. Messing with it might allow it to engage and then fail in the locked state making the car undriveable.

 

thanks for the reply! I suppose I’ll leave it as it is for now then. However, I’ll have to tackle this sometime in the future as a functioning steering lock is mandatory for the German TÜV inspection. If I’ve done my research correctly, fixing this would mean I’d have to replace the two relays in the steering lock unit, right?

Thanks,

DHL

 

i have the same exact issue.
i would like to know a bit more about this and why the car becomes undrivable? whats wrong with just replacing the part?

 

If it's just the physical locking mechanism itself that's the issue, you can replace it, but part of that same system is that Kessy Enter and Drive system where the module in the steering column has to recognize the key and when it stops communicating correctly it completely disabled the vehicle. There have been a few threads on here about that issue and people removing the circuitry and sending it off for repair instead of replacing their complete steering column, which is Porsches only solution, that sometimes doesn't even work.

 

Hey all…did anyone ever figure out what was wrong here? I have the same year and model and same issue. Looking for help. TIA

 

Don‘t know if anyone got this fixed yet, but I dug into it today.

I‘ve removed the locking module from the column as shown in this YouTube video:


I thought the issue surely is something faulty in there. However, the unit is perfectly fine. The locking mechanism engages and disengages all the way.

When I had the unit removed, I had a look at the column. The ELV moves a little slider on the column itself (attached with the torx screw to the ELV). Now that I had the unit removed, I manually moved the slider all the way into the locking position, even applied a bit of pressure to it. The problem still persists.
Apparently something inside the column itself is broken. Now I didn’t have the time to do anything more today, but the „clicking“-sound seems to be coming from right around where the steering wheel is attached. Maybe I’ll be able to disassemble the column further tomorrow, but it looks like a bloody nightmare to do. Maybe somebody here has some advice, my car has the electronically adjustable column.

 

I know this is an old topic. Has anyone ever solve this problem? I have the same problem too. I have a Porsche Cayenne 955 turbo 2003 with keyless entry. I was having water problem (leaking in the car) and had to repair the corroded cables under the carpet.
Do I need a new ignition module or any other part?

 

If this failed on my car I would try to remove the locking pin or slider so it doesn't lock the steering wheel. It's an anti-theft device...just have insurance instead.
