I have a new headliner waiting at the dealer for me. I will be modifying one of my pistol safes to lock the obd2 connector in. Just remove the screws holding it to the knee brace and lock the connector in the case with a slot for the cord to pass through.
Slight problem with your solution - every cable has 2 ends. If VWOA mandates the vandalism on any car brought in, when you go to collect your car you'll find that your bill includes a new cable, and your old one was snipped off where it enters the pistol box.
A different solution (this one WILL void your warranty) is to, when the repair order for what YOU want fixed is written up, insist on it having the wording "This vehicle has aftermarket equipment incompatible with VW diagnostic tools connected to the CAN bus. DO NOT connect anything to the OBD2 connector - such a connection may cause damage to the vehicle and/or the connected equipment". Of course, you'd need to prepare in advance - unhook the connector from the stock harness, and connect it to your aftermarket equipment. What aftermarket equipment? A device which will detect an attempt to read from the connector, and on sensing this discharges roughly 500 microfarads of capacitors charged up to 500 volts down the data line. This should be enough of a jolt to "burn through" protective devices such as fuses (intended to catch a line pulled to rail by something like an aftermarket radio, and not expected to block a high voltage surge) and hit the computer itself. They complain that their computer stopped working when they hooked it up to your car? Obviously didn't read the work order, which SAID that there was incompatible equipment on the bus, and that they must not hook up to it.
In the past we've seen buybacks ordered by the NTSB for safety issues, but has there ever been a case where consumers were actually forced to give up their cars?
General Motors EV1. Admittedly they were only ever leased, not sold.
Those German engineers are pretty darn smart. Almost got away with it.
Seeing your avatar, I've got to add "And they would have got away with it if not for those meddling kids at WVU"
One thing I haven't seen mention of in connection with VWOA's "stop sale" order - what about leased cars where the lease is coming to an end? The leasing contract would give the customer the option of buying the vehicle for a specified price, and if the "stop sale" order comes from VWOA instead of the regulator, company policy does NOT override a contract. The person who had leased the vehicle, and wanted to buy it out at the end of the lease, could sue for specific performance (i.e. to get VW ordered to sell them the car, as specified in their lease contract). Would be interesting to see what happens if someone at the end of their lease shows up at the dealership (using alternate transportation to avoid the dealer being able to block the car in and keep them from taking it off the lot again) with a certified cheque for the buyout value.
