The car just threw this fault out nowhere. Now it has no ignition and no start, Just a message on the dash that says "steering Fault". My research leads me to believe there is a module in the steering column that has gone bad. The question is what do I need to do before and after I replace this module? I am going to run a full scan, but I fear many of the modules will not respond since the ignition has been disabled. But I'm going to give it a try and see. I will post the results.

So no luck with a scan. VCDS gives me a no communication error. I assume because there is no ignition on and the OBD system is not powered up. What now?

What's the exact message from VCDS?

Try going directly to 19-CAN gateway and see if it talks and has any faults. Also try 05-Acc/Start Auth.

There may also be some song-and-dance involving the brake pedal and possibly the hazard light switch that can get enough things powered up to communicate, but I don't have exact details for this vehicle.

I agree with Uwe. Do see if 05 or 19 will respond directly. There are 3 primary methods to wake broken KESSY cars. Those were:

* Foot on brake pedal (for roughly 20 seconds) before turning on the ignition.
* High beam stalk held in the flash to pass position.
* 4-way flasher / hazard light switch on.

You can do all 3 at the same time when in doubt.

Just make sure to keep the battery fully charged and keep in mind the dash/terminal 15 does NOT magically wake up and turn on. Instead, this wake-up process only lets you communicate to modules (such as 05 and 19). However, providing 05 communicates and has an intermittent DTC that can be cleared the vehicle may power on properly until the problem reoccurs.

The message from VCDS says "Failure to Communicate (0), Please use (options) > (Test) for further details."
When I go to options > Test, it appears to be communicating with the interface.

No luck getting into 19-CAN or 5-CAN. I get the same error on both.

Clear faults in 05-Acc/Start Auth.

Hopefully then the rest of the car will power up.

No luck, Cleared the codes in 05 and they come right back. So I cleared all the codes and the same thing.....no ignition - no start - steering fault displayed on the dash.
So I guess it's safe to assume the steering lock module (J764) is bad?

I'm not sure that's a safe assumption, but it doesn't strike me as unlikely either.

I know I wouldn't want that pin sliding into the lock position while driving let alone not moving on a cold/hot day, would you?

My recommendation is to report it to NHTSA, as a safety issue and two if it were mine I'd remove the lock pin so lock module doesn't do anymore work.

As you can see the system did not help you or prevent theft, it is however a creative way of using the inverse spec's of NHTSA and EPA to enrich someone now isn't it?

Sound's like a worn micro switch, open photo and investigate no?

I agree with the guys here. Unless you have a voltage supply problem to it (which is unlikely) the ESCL / 4H0 905 852 B is likely faulty. Even if you can get it unjammed/functioning well enough that the vehicle will start I wouldn't trust it (long term) bolted to my steering column since it could malfunction while driving as Jack mentioned.

Replacement would be the best option but the new unit will need to be matched to the Immo online at the dealer if you don't have a mobile tech or locksmith with ODIS setup that can come to you. For that reason taking it apart and investigating might be worthwhile in the event you can save yourself a tow to dealer.
