Vcds scan at dealer acceptable?

[Jimingle10]

Had a chance to test drive an S8 today and I brought my laptop and VCDS cable with me. Test drive wasn't good, car had a solid shudder around 3k rpm, didn't feel like a misfire and didn't throw a CEL. I asked the salesman if I could scan the car and he said sure. Once I pulled out a laptop he went inside to presumably update his manager... Then came SPRINTING out saying stop, you cannot do that. I aborted the scan but atleast 9 modules showed malfunction and I got the engine codes.

Mind you this was not an Audi dealer, but another brand name that happened to have an S8 on the lot.

My question is, is it acceptable to auto scan a car? These people treated me like a terrorist/hacker and were extremely rude after the incident. I explained exactly what the tool was and showed the cable and the partial results I did obtain. He responded with "are you ready to talk numbers?" Like what? I said no thanks and this is a deal breaker. They ended up showing me the door when I said this is a deal breaker especially given the car not running right. No goodbye or thanks for coming by, the guy just went back to the S8 and parked it. I have no interest in the car or this dealer at this point but curious if anyone had tried to scan a car and had issues with it? This is a car listed close to $45k and obviously no warranty.

I always ask for permission to scan for fault codes and have never received "NO" for answer. I usually show the results of the scan as sort of tool for negotiating for lower price if the car still is interesting for me.
And at the end of scan I offer to delete the codes (so that after the test drive I could see if any came back).

Would this happen to be at a Hyundai/Kia dealer?

Yep

Yep

Outside of the fact that the carfax shows 2 accidents within 3 months of each other, I’m really not too surprised to hear that a H/K dealer wouldn’t want someone to hook up a scan tool or any other OB electronic device given the landscape of the H/K security issues. Walking is the right choice.

I was curious because it is a low mile car. The accidents were when it was close to new so in theory should have been fixed correctly. The odd part is how it wasn't driven for a few years and now appears for sale at Hyundai. The dealer also owns an Audi dealership and why they wouldn't put a flagship car like this on Audi lot raises questions

I'll go ahead and post the link to the car for anyone else following. Looks good on the surface with low miles and single owner but something isn't right.

They clearly seem to know something is wrong with the car and as you point out, the fact that they won’t place this at their network Audi dealer makes it more suspicious. An alternative to scanning yourself would be asking it to be sent to the Audi dealer in their network but it seems unlikely they would bite on that either.

I had no interest in the car, but your post peeked my interest and I jokingly guessed that it was a H/K dealer before I went looking and sure enough found a S8 in the criteria stated. I think you’re making the right choice on passing and that the work from the accidents could be correctly fixed. The length of disuse certainly reads like a recent graduate’s resume with a few gap years unaccounted for.
