For the second time I had the steering column lock fault message today which completely disables the car ( including not being able to switch the ignition off ). At least this time it did reset itself after about 20 minutes before the mechanic (electrician?!) arrived, whereas last time it had to be flat-bedded 100 miles back to the dealer. When the laptop was plugged in it showed a number of faults recorded with the main one being " steering column lock incorrect password".
I have asked the dealer to log it with Vauxhall and I will feed back their response.

The password as I understand it is held within the cars system and is automatically generated when you start it. I'm not quite sure how you would enter a code as you suggest Jack or at least from the screen that the mechanic had when he coupled the laptop which just listed the faults which all subsequently cleared.

It was a joke :p likely each module has a signature that it signals the CAN bus with. If the message from a module isn't signed with the appropriate signature the receiving module then refuses it - causing the fault. As its steering related I would surmise the tolerance for incorrect data is zero, so will fault almost immediately if anything is out of the ordinary.

Very odd :(
Might be worth spending £5 on an odb2 dongle, as I suspect just plugging it in will clear the fault .....

Had this myself yesterday. After a 250 mile drive from Manchester (so all on petrol) when I arrived home and switched off I had the message "service steering column" and the inevitable beeps and bongs. The car is completely disabled. When you open the door the steering lock engages as normal (I must admit I'd never really noticed before that it only engages the lock when you open the door) but trying to restart gets a "turn steering wheel and restart" message with a clicking noise from the steering column. Obviously I tried the turn-the-wheel thing but made no difference.

I then tried the superstitious stuff you read like "lock it and walk 100 yards away" and "give it a full re-charge" but all to no avail. I also tried reading the codes using the ODB2 dongle but there were none so I cleared them anyway but still no good.

I then started to pull various fuses thinking that may reset something (ECU etc). There is a fuse F2 in the fusebox to right of the driver called Steering Column and when I pulled that I noticed it was coated in a white powdery residue, so much so that I doubted it would make an electrical contact. I cleaned it off, replaced it and it worked! As a check I pulled the fuse again, tried a restart with the fuse out and got the same fault. Fuse back in, worked fine.

Impossible to know for sure if it was the fuse (would it have cleared at that moment anyway?) but I'm pretty convinced that it was ...

Good detective work !

I've got my ODB2 dongle all primed to try next time the car locks out on me and you've beaten me to it! When (and it will be when) it next happens I shall give the F2 fuse a pull and see if we can definitely pinpoint this as a fix. I am still waiting for Vauxhall to come back to me after my last lock out but will start harassing them in about a week.

This happened to me twice a couple of years ago, including the whole not being able to switch the car off thing which eventually reset after a few minutes. Vauxhall said I must have been parked against a curb out on uneven ground, but once was on my brother's drive and the second was in a flat parking space at a little chef well away from any curb. They never did detect a fault when they had the car in next.

I will say, though, I have never seen a car with so many fuses. I've had cars with less fuses than this car has fuse BOXES!!

Note to self - any faults, go check the fuses.

I had this myself today. I had previously seen the steering column lock fault a couple of times before, both when I had failed to give the car a full charge (at the dealership in fact!) but I was previously able to get it to go away by power cycling and it hasn't happened since April. This time that didn't work.

I was parked in a narrow street where you are expected to park with the right side of the car on the curb, so there appears to be some truth in the idea that non-level parking can upset it. It is also possible that I stepped on the brake pedal when I first switched the car off.

On my return to the car a few minutes later it powered up normally but showed the error message and I could not move the steering wheel or get it out of Park. I did not notice any clicking noises. I was able to turn the car off, and did so, waited 30 secs or so and then powered up again and got the same result. Attempting to power down, I had some trouble (it didn't go off) but eventually I was successful. Powering up again after a minute or two I got the same result. I then turned it off and left the car, which gave me a triple beep, presumably indicating that the key fob was not where it expected it to be (it was in my pocket). Returning to the car after a couple of minutes I powered the car up and the message did not reappear.

This is rather disturbing, and as it appears to have been known for a long time, I would be most grateful for the current state of knowledge on this issue if any more is known than appears in this thread, such as a series of things that one can try.

Many thanks in advance.

PS: Oh, and which of the many ODB2 devices would be recommended and what would I be able to do with it if I had one?

Derekb..

The service steering lock message came up last night after a few hours of charging following a 130 odd mile trip to Canterbury. I (eventually) managed to get the f2 fuse out and noticed the white crust covering the blades. After scraping these clean and refitting the fuse, message was gone.
Thanks for the heads up.
