Audi misery deepens as Miami disqualification looms

Gabriel Bortoleto is facing disqualification from the Miami Grand Prix Sprint - on a bad day for Audi. 

Pre-race, Nico Hulkenberg suffered a fiery failure on the way to the grid and did not take to the start, with team-mate Bortoleto finishing 11th on the road. 

However, during the routine post-Sprint technical inspection, it was found by the FIA that the engine air-intake pressure exceeded the permitted amount. 

The maximum limit is 4.8 bar, with the Brazilian RS26 exceeding this. 

Such technical breaches are often followed by a simple disqualification.
