Hello.

I'm new here and, of course, I've already used the search function, but I couldn't find anything relevant.

Question: Do you have experience with the continuous monitoring of engine functions in a vehicle using a car PC (and, of course, VAG systems)?
What should I pay attention to, or what should I avoid doing?

My longest trip on a single charge covered over 1600 km, almost continuously (excluding stops with the motor turned off).

you need:

- a high-quality adapter -> shop
- ensure a secure attachment of your 'diagnostic device,' whatever that may be.
- enough brain to tell you: 'get off the road!'

hazards:

- Acceleration of the vehicle at -100g because you end up crashing into a tree while fiddling with your laptop.
- The vehicle accelerated at -1.5g because Aunt Erna swerved suddenly, causing the laptop to land in the footwell.

Sure, here is the translation of the text from German to English:

'other:'

- This whole process isn't really real-time. VAG-COM achieves 1.5 to 3 samples per second with a single measurement block. The K-line simply doesn't allow for more. With two measurement blocks, you can achieve approximately 1 sample per second. While this is usable for continuous logging, it's not suitable for a real-time display of engine speed or boost pressure.
- Analyzing such log files can take a VERY long time...

With EDC-16, it's possible to achieve more than 30 samples per second! It's even faster on the K-line than over CAN! Okay, the fault is located in the EDC-15 engine control unit, not on the K-line, and not in VAG-COM.

Thank you for the answers. So, I can do it without any problems. Don't you have to worry about the airbags deploying if the computer crashes?

No, only if you're leaving the street at the same time the car crashes.

@Gremlin

'Nojo, our company laptop has already undergone quite a bit of acceleration (it was involved in an accident at 80 km/h when I left the road, resulting in an axle break, deployed airbags, and a warped frame).' The laptop was there, but it was turned off.

Best regards, WarLord.
