That doesn't add up. No one pays for a full inspection and TÜV on top because no one expects a 3 year old car to fail it. It's not just slightly inflated either

That doesn't add up. No one pays for a full inspection and TÜV on top because no one expects a 3 year old car to fail it. It's not just slightly inflated either, 10% is twice of the average and the problems seem concentrated around suspension, a part that isn't expected to fail until much, much later in the car lifecycle - hardly the result of average wear and tear.
