Nick Heidfeld admitted to frustration on Sunday because he thought a gearbox problem robbed him of a sure podium bid at the Spanish GP.
But the German was also pointing a finger at the BMW-Sauber team for botching a scheduled visit to the pits, when the ‘lollipop man’ released him before his right front wheel was fitted.
30-year-old Heidfeld said his real dissatisfaction kicked in when, seeing the errant wheel nut flying away, he stopped just metres from his pit area but was not attended to by his crew.
Heidfeld then sped away and had to complete a lap at slow speed before returning to the pit lane for a new nut.
“I have no idea why no-one came to help me,” he told the German newspaper Bild.
“We definitely need to talk about that because it must never happen again.”
