We went on vacation and had the tire pressure is not controlled, barely on the highway going to the warning lamp. After the tire pressure was correct, blinking continues the system lamp. :(
So there were two ways to leave either in the workshop and read the memory and delete. I think the 30 euro come about right. Or buy this device and itself is the man.
Conclusion: For some error codes sure the correct device, but if it gets too haarisch, you can still visit the shop! I highly recommend it.
