A 33-year-old Pratt Island Road resident still is in the hospital following a one-car accident on Nearwater Lane in Darien June 6, police said.

He was behind the wheel of a 2015 Audi A3 when he drove the car off the road, hit an embankment and went airborne, Darien police said. Representatives from Audi and an investigator from the state Department of Motor Vehicles examined the car on Friday after police received a search warrant.

The 2015 Audi A3 has only been on the market since March, and police want to rule out any mechanical issues as the cause of the accident. Police said one of the three control modules, which communicate with each other and store data, was completely destroyed.

Police said they're unable to obtain data from the car because Volkswagen, which owns Audi, is in negotiations with Bosch, the company that designed the cable necessary to download the information.

Just before 11 p.m. June 6, police responded to a report of a car accident. Police said speed was a factor in the accident, during which the underside of the car clipped a stonewall before partially nose diving and slamming into a tree. The Noroton Fire Department responded to the scene and spent 30 minutes extricating the man from the vehicle, according to the report.

The engine was dislodged from the vehicle and was found 15 feet from the scene of the accident, police said.

Police said the man sustained several life-threatening injuries and was transported to Stamford Hospital. Police have not spoken with him yet.
