Hi All,

I have an issue with my friend's 2010 R36 that I'd be interested in any input to try and solve.

At Christmas last year he had his battery replaced. Once the new battery was in he got an immo fault and the car would not start. He had it towed to a workshop but they were too busy to look at it leading up to shutdown over the holidays.
After some attempts to resolve it I determined that the ELV had somehow become corrupted. Managed to order a new ELV from VW spares just before they shut also.
Replaced the ELV and much to everyone's relief the car was able to start again and he didn't have to leave it outside the workshop.
Fast forward to yesterday. I had rebuilt a set of headlights with new projectors to replace his that had burnt out so were very dull. Took the bumper off, replaced the headlights. Bumper back on, quick adjustment, then we drove out to a dark area to test them and do a better alignment. Car would have been turned off and started again maybe half a dozen times.

Very happy with the result he drove home.

The next morning he went to start the car. Instrument cluster comes on, but no crank at all. Disconnect battery, try again - nothing.

I checked for faults - no immo or other faults logged.
Checked measuring values and can see in immo that engine start is not permitted.
Pulled out the 3AA CCM, read eeprom and compare immo data against backups of this original 3C0 CCM and ELV, as well as the newer 3AA CCM and the new replacement ELV from the beginning of the year. Data all looks good.
Swapped out the CCM for a spare just in case after copying in the data - still no start.

Unplugged ELV and plugged in the original factory part which I still have, reverted CCM data to the original ELV MAC.
Now the car is back to how it was at Christmas - key doesn't turn on the cluster any more. Diagnostics on immo is flaky - can't clear faults, PIN is not accepted. So it appears that my original diagnosis of a corrupt ELV is still valid.
Plugged new ELV back in and CCM eeprom data to match.

At this point I think I may possibly have made a mistake - I thought I could possibly 'resynch' the ELV, as it was already matched to this car. I used the procedure (enter immo, adaptation channel 0, save, then enter PIN in SA, change value 32000 to PIN) but WAIT status changes straight away to NOT OK. Many variations of trying to get this sequence to complete and it's always the same. I tried the procedure through ODIS and it fails reporting that ELV is not a new part. Which it isn't (although it's from this car having been working successfully for months).

Have checked all fuses etc the problem appears on the surface to be another ELV failure. Seems WAY too coincidental that I did some (seemingly) unrelated work on it, car was then fine but following morning was a large paperweight in his driveway)

So if you're still with me after this lengthy story there are a few questions...
1. can a 'used' ELV be relearnt IF IT IS FROM THE SAME CAR?
2. has anyone seen a rev J ELV just stop working out of the blue like this?
3. Any other suggestions before I buy another ELV and hope that fixes it?
4. Any theories as to why this might have occurred? (there is much FOD in this car but as mentioned it was working well for quite some time now)

Below is an autoscan which is not current. Apologies I was working late last night in much frustration and didn't save a scan. Current fault in immo is ELV no basic settings.

Why on the Earth you would think something is wrong with immobilizer or EVL if the car do not crank. Maybe is simply Starter when out or Ignition switch (yes Part that you put key in ,I have seen this fail.)


Checked measuring values and can see in immo that engine start is not permitted.
In most of the time it will be like that on this car till you start Engine .

Yes the ignition switch (funky one in the Passat is the 3 stage hole where the fob goes in) can fail. I don't believe this is the case here but it's certainly worth investigating further.

MVB 1-1 (engine start permitted) shows 'No'. So either the ECU, CCM or ELV don't agree to allow engine start. This is with key at ign position.
I checked this against my car, which shows 'yes' when key is at this same second position- terminal 15.
Key status is valid for both keys.

I'm confident I've ruled out the CCM as I've validated the data, and used another CCM. ECU I can't rule out as I haven't got another ECU on hand, but I think this is likely a low probability. I can get hold of another MED9.1 and get the immo data transfered over using tuning tools at a friend's workshop if that something that is required.

Either way I feel like I've now broken the ELV by attempting the learning procedure on a 'used' part. So I think I'll have to get a new one next week at a minimum, unless there is some way of getting this one back to a synchronised state?

This will not stop car form Cranking, Car will still crank , start and turn off after 2-3 seconds if ECU in not Authorized , You said car will NOT CRANK, That means you have other problem besides this .So you started with wrong diagnostic . Maybe now all is mess up since you tried many unnecessary thing.

Yes so I definitely went down the rabbit hole on that given the experience I had last time with the ELV (it had an internal checksum fault.)
So I went back to my friend's place last night with a new ELV.
Before I started pulling out the steering column I thought I'd take another autoscan and at least save it this time.
The missing basic settings fault on ELV was gone!
Engine start permitted was now 'yes'.
Using the multimeter I tested all the engine bay fuses (my friend had inspected but just visually) and found a faulty 10amp fuse (SB33 I think from memory).
Car started fine :)
Will return the unused ELV as they aren't that cheap...

Good advice as always. I troubleshoot for a living (not cars) and should take my own advice - step back, start with the basics and only then move forward. haha
