Audi recalling 70k TDI models worldwide over braking problem

Audi is issuing a recall covering some 70,000 vehicles worldwide, due to problems with their brake boosters. According to Automotive News Europe, diesel-powered examples of the A4, A5, A6, A7 and Q7 are all being called back due to this issue.
The report indicates that while the brakes in these vehicles still function, the enhancing power from the booster may fail due to a possible leaky membrane.
All of the affected vehicles are powered by the 3.0-liter TDI turbodiesel V6, and were built between March and December of 2012. It is unclear as of this writing how many of these vehicles are in the States, though remember, US customers are not privy to 3.0 TDI examples of the A4 or A5. Autoblog has reached out to Audi for specific numbers, and we'll update this space when we hear more.

US-bound Audi A3 Sedan spied testing

As the Audi A3 sedan gets closer to its debut, Audi has camouflaged prototypes to take it on the streets for final testing. Last time we saw the A3, it was testing almost in the buff, but it was on a closed track so our spy shooters were kept at quite a distance.
Now that the newest Audi sedan is testing on public roads, our latest batch of spy shots gives us a more detailed look at the entry-level luxury player despite the swirly camo. Except for the oversized wheels and the fancy exhaust outlets and door mirrors, the production version of the car should look almost identical to the A3 sedan concept we saw in Geneva a couple years ago. Some of the details we can see include a good-sized panoramic roof that stretches almost halfway into the rear passenger space and signature Audi LED-accented headlights and taillights.

Audi promises production laser headlights

Audi is showing off new laser headlight technology this week at the 2014 Consumer Electronics Show on its Audi Sport Quattro Laserlight Concept, and most intriguingly, the automaker has plans to use the long-range lighting on production vehicles. Audi CEO Rupert Stadler tells Automotive News that this type of headlights will be used on a future production vehicle, although he did not specify any timeframe.
On the concept vehicle, the headlights employ LED low beams, while the high beams use the laserlight technology. Audi says that these lights are not only very small ("a few microns in diameter") they are also able to light the road for almost a third of a mile (1,640 feet), with three times the brightness of an LED highbeam, yet with pinpoint control. These lights have already been confirmed for use in motorsports on the 2014 Audi R18 e-tron Quattro LMP1 racecar, and the tech will eventually trickle down to road-going cars.
In addition to how long this trickle down will take, it's doubtful we'll see these lights in the US anytime soon. Audi is still working with the US Department of Transportation for approval of its LED Matrix Beam headlights, which are already sold in other markets, and the negotiations appear to be taking quite a bit of time. Automotive News also notes that the laser headlights earmarked as options on the 2015 BMW i8 will not be offered in the US, either.
