HitechGP driver Ben Barnicoat has been excluded from the final European Formula 3 Championship race at the Norisring for a technical infringement with his car's floor.
Stewards found that the car failed to comply with article 3.14 of the F3 technical regulations.
The front left corner of the floor on Barnicoat's Dallara-Volkswagen was deemed to be lower than the threshold allowed and he was stripped of his ninth place finish.
The British driver's team had replaced the floor overnight following a heavy crash in the second race around the Nuremberg streets, when Barnicoat was tipped into the Turn 5 wall by Ryan Tveter.
HitechGP director Oliver Oakes was baffled by the problem, as the car - with its new floor - was cleared after being measured on the legality patch in the early hours of Sunday morning.
"It is just the front left corner of his floor, a little bit disappointing but rules are rules," Oakes told Autosport.
"Given the circumstances it is a bit of a nightmare.
"It was another floor we had fitted; it wasn't the same floor [as the one involved in the race two crash].
"I don't want to blame people in this situation, it is just a bit annoying as we did go on the patch in the early hours of the morning and it was fine.
"Until we get back to the workshop and analyse everything I can't say much more."
Several other drivers picked up penalties after race three at the Norisring.
Mucke Motorsport team-mates Mikkel Jensen and David Beckmann both received three-place grid drops for race one at Zandvoort plus a penalty point apiece for colliding with each other.
Van Amersfoort Racing's Pedro Piquet was given a written reprimand and one penalty point by the stewards for causing the incident that led to the race being red-flagged early on.
Piquet ran into Tveter and was launched into the air before collecting Niko Kari.
