2010 VW Passat Power question

No Dash Ligths Or Ignition
Security Theft / No Start

This question is in regards to this 2010 Passat. I towed this to my shop today to add some keys. Steering Wheel is locked, IMO is “active”, Parking Brake is locked. So first question is, should I not at least be able to get the ignition turned on when I insert an “Unprogrammed” Key? I don't work on german Cars that much so be easy on me.

Thanks!!

Un-programmed keys on a VW will start the car for a second then immediately turn off. If nothing comes on at all you most likely have a failed steering lock control module. This is common on this vehicle.

As an update, I took the Convenience Module out desoldered the chip, loaded in my autel and everything checked OK. I Created 2 Dealer Keys and message was “Key write success” so I figured everything worked as planned. When I plugged the Module back in I quickly realized the message was still there and still no Ignition. I'm not new to replacing chips, bench programming and all the other good…

Sorry been on Vacation. Update! These unprogrammed Keys will in fact do nothing at all with the IMO locked. Once I properly read the Chip and programmed it(inside the comfort Module) is now working as it should.

Hello Ralf, I have to ask the obvious, What happened to the original keys? Did you verify the owner of the vehicle with a proof of insurance? There has been some strange theft scenarios going on all around the country lately. Some are just REPO jobs while others are a divorce mess. Tow drivers are supposed to verify before hooking up, but that is not always true or reliable. Normally, a finance…

LOL This is a little old lady that had the car forever she is likely close to 80 but someone has already messed with this thing as I was told the only thing wrong was the keys missing. Church is paying the bill so I want to make sure I don't get to many hrs in this job.

I second what Travis stated…..It might be easier to directly loosen the handbrake at the motors on each wheel with a Powerprobe that bridging the relay.

If this is FOB style Key with the Ignition box you put them in you will need ODIS to correctly register them. Those FOB keys while physically any will insert them into the ignition node, the electronic ID is registered to a specific VIN on the security FAZ server. If you attempt to register a Key not registered to this VIN you will Lockout the immobilizer and the vehicle will require a ‘new…

Sorry been on Vacation. Update! You are not entirely correct. All you have to do is unsolder the 8 prong chip from the Comfort module and write new dealer Keys. I did it incorrectly the first time that is why I had all the problems.

With VW/Audi we run the epb’s in with the power probe right at the calipers. Then it can be pushed into the shop, where we use ODIS. It will power up terminal 15 and you’re good to go. If no ODIS, get to the terminal 15 power supply, relay usually in the under dash relay center by drivers feet. Jump that bad boy, and you’re good to go. It does sound like the typical bad steering column lock…

Sorry been on Vacation. Update! Nothing wrong with any of it! Just needed to properly code a chip inside the comfort module! Thanks!
