Thanks UWE & Boki,
As these are my first posts, I wasn't sure if "New User Forum" was the correct place to explain the issue.
This is my son's Passat. A 2001 GLX V6.
He (and the car) are about three hours away at Western Kentucky University in Bowling Green, KY.
I drove down last weekend to attempt to get it started and drive it home. No Luck.
The key is not being recognized. I get a flashing Immobi Key when turning the keyswitch to on.
Lower MFA LED reads - "Immobil activated" a few seconds after key is turned on.
Removed the plastic covers around the ignition switch to expose the connectors and wiring.
Removed the key tumbler. Cleaned the immobilizer coil connector (part on keyswitch that reads the RFID chip), plugged & unplugged it a few times. No help.
Checked resistance on that immo coil - 23.1 ohms as I recall. Read a post somewhere that 24 ohms was good.
Tried disconnecting battery / touching leads for 10 plus seconds.
Did not remove the instrument cluster to check it's connection.
It was raining from the Harvey storm and the car is uncovered in a student parking lot. Kinda put a damper on things..
The instrument cluster has never been out of this car, no chipping, mod's ,etc..
It's a half height MFA LED display and has always faded to the point it's almost unreadable in warm weather.
If it's needed later or for troubleshooting, I did purchase a new replacement cluster back when VW clearanced them out.
Back then, it needed to be coded to install and we just didn't have an immediate need to do that.
I drove back home (Cincinnati, OH area) and am now making my next plan of attack..
Called my local VW dealer and spoke with the service tech (who was very helpful for a phone conversation).
I was wondering if the RFID chips in keys ever go "bad".
Tech said yes but in his experience, they are either good or bad. No in between's.
To me, that may rule out the RFID chip. This car's immobilzer not starting issue has come and gone a couple times in the past month.
Long story short, the only key with transponder we have is the one we are using (it has worked fine for the past few years).
We do have another key blank that will turn the switch but it's RFID chip has not been coded to the car.
Took some pics of the screens during the scan and coped the scan below.
Regards, Ken
