Jul.23 (Reuters) Toro Rosso’s Sebastien Buemi has been excluded from the results of German Grand Prix qualifying because of fuel irregularities, Formula 1 stewards said in a statement on Saturday.

The Swiss took 16th on the grid for Sunday’s race but is now expected to start from the pits pending a possible appeal.

FIA  statement:
“The stewards, having received a report from the FIA Technical Delegate that the fuel sample taken after Qualifying from Car 18 showed an increase in one given GC Peak Area of an absolute amount greater than 0.1 per cent for the component present at a concentration below 0.8 per cent, and having heard from the FIA Formula One Analytical Chemist and the Team Representatives and examined the fuel test graphs, determine this to be a breach of Article 19.8.3 of the 2011 FiA Formula One Technical Regulations and decide to impose a penalty of exclusion of Car 18 from the results of Qualifying.”

Toro Rosso response and explanation:
“During Friday’s FP1, Buemi’s car had a fuel pressure problem, which then got worse at the start of FP2 which is why he did not do a timed lap in that session. After FP2 the entire fuel system on his car was changed. When the fuel sample was taken from his car after qualifying, it did not match the one provided to the FIA prior to the start of the season. The team believes that some part of the new fuel system contained a chemical that contaminated the fuel and caused the non-conformity.”
