Countless BMW owners have been frustrated for some time with software-induced turbo lag on their N54 3.0-liter twin-turbo inline-6 engines. While early models were acclaimed for their immediate power delivery, it seems BMW felt it necessary to address "specific noise concerns" with the engine and made software changes in models built between June 2006 and March 2008. Those changes introduced turbo lag – the noticeable delay between the throttle and the time it takes for the turbocharger to spin and produce power. Enthusiasts were up in arms, but BMW refused to recognize their concerns (addressed on nearly every BMW message board, and by the BMW Car Club of America)... until now. According to a statement from the automaker, new software will be released in January 2009 that will restore the original turbocharger response. Of course, it comes with a warning that it may result in "slightly increased engine noise levels." As if an enthusiast cares... Thanks for the tip Michael!

Economic doom and gloom might have you thinking differently about the vehicle sitting in your driveway. Keeping it alive a few extra years will head off increased expense, and cars are easily able to reach beyond 100,000 miles these days. Inveterate wrench-turners have long relished stretching their dollar by breaking out the tools. When you spend less than ten bucks to solder in a new set of regulator brushes in your alternator, you feel like you've won something; you've certainly saved a fistful of cash. So what do you spend time on repairing yourself versus going with remanufactured or new parts? Popular Mechanics has a quick guide that makes some good points about the repair versus replace conundrum. The general gist is that you'll be spending more time rebuilding calipers and rodding out radiator cores on your Fury III than you might on a Chevy Lumina, though both vehicles can be kept roadworthy for as long as you please with some savvy maintenance and repair without breaking the bank.

Regardless of where you stand on the validity of Consumer Reports' testing and survey methods, there's millions of people out there who consider the magazine their buying bible. Thus, it's news when the non-profit releases findings from a new subscriber-based survey. This time it's the 2008 Reliability Survey, and while you'll have to buy the latest issue of Consumer Reports to see how your favorite favorite brand or model in particular performed, the overall trends indicate that fuel efficient vehicles, whether they be hybrids or just small gas-powered cars, are very reliable. Also, Ford is reportedly pulling away from its domestic rivals in the reliability arena with the majority of its models, including Lincoln and Mercury vehicles, now scoring above the industry average.

You may recall the shock from last year's survey in which three Toyota models – the Camry V6, Tundra V8 4WD and Lexus GS AWD – all fell below average in predicted reliability. Consumer Reports says that those three models have clawed their way back up to average reliability scores, while every other Toyota, Lexus and Scion model in the survey scored average or better. Finally, while European brands are reportedly improving their reliability, many models remain below average and Land Rover has again came up dead last with all four of its SUVs scoring far below average. Oh, and remember when Jeremy Clarkson called the Chrysler Sebring Convertible the "worst car in the entire world"? Apparently CR subscribers who own one agree, scoring it worst in reliability of all the models surveyed and 283% below the average.

Owners of the new crop of clean diesels will have another maintenance item to concern themselves with if their new cars are equipped with urea injection. The EPA requires that all diesels meet strict new emissions standards, which almost always requires the use of either a NOx trap or urea injection. To ensure that the system is working, a sensor checks both the level and the quality of the urea solution and will keep the car from starting if the tank is empty. The new VW Jetta TDI doesn't use urea, but the new Mercedes-Benz BlueTEC vehicles do. According to Mercedes, a counter will appear on the dash when there are twenty starts remaining. If the driver ignores the message, the car will not operate until at least two gallons of urea solution is added to the tamper-proof tank that resides in the spare tire well.

Engineers have designed the urea tanks to be large enough to last about 15,000 miles. This should be large enough that drivers never run out, as the tanks will be checked at every schedules service. As an alternative, small bottles of the urea solution will be available for owners who want to maintain the system themselves. The cost of the urea solution, which MB refers to as AdBlue, will mirror the cost of diesel fuel, so a refill shouldn't cost more than $30 or so. Before anybody asks, yes - urea is a component of urine, and no - peeing in the tank will not fool the sensors. You've been warned.

Reminding us once again that there's more than meets the eye when shopping for a vehicle are recent impact tests performed by the Insurance Institute for Highway Safety that measure how much it costs to fix a vehicle after after a low-speed accident. Sure, we're all interested in safety and styling, but we should also be concerned with how much these low-speed impacts will cost to repair. The winner of the testing was the Ford Focus, which scored light damage all the way around. The IIHS heaped praise on Ford for designing a bumper that can truly take a bump -- a novel idea.

Amazingly, some small cars like the Hyundai Elantra, Toyota Prius and VW Rabbit cost up to a third of the car's worth to fix from damage resulting from a minor impact. That's a big problem for any car, but especially so for those sold on the merits of economy. To prove that it's not too difficult for auto manufacturers to design a better bumper, the IIHS made a few simple changes to a Prius that didn't affect the looks of the car. After retesting, it made it through the impact tests with a fraction of the damage. For the complete rundown on the testing procedures and results, click past the break.

BMW's N54 engine has won the International Engine of the Year award for the past two straight years. It has also been listed as one of Ward's 10 Best Engines during the same period. The engine produces 306 hp and 295 ft-lbs of torque in a 3.0L inline six package thanks to the use of twin Mitsubishi turbochargers and direct injection. The N54's quick response and smooth torque curve has been an attraction for many enthusiasts, including myself - I call my Montego Blue coupe the turbo Cookie Monster. That is why a few BMW 335i owners are miffed by a feeling of reduced performance after a recent service update. Posters on the BMW forum e90post.com claim that a software update to adjust rattling wastegate valves has induced lag into the turbochargers that wasn't there before.

As illustrated in the gallery below, the N54 turbochargers differ from most setups in that the wastegates default to the open position. This allows for better emissions due to the ability of the exhaust gas to bypass the turbochargers on start up so the catalytic converters can heat up faster. It certainly follows suit that BMW has the ability to adjust the ECU settings in order to hold those wastegates open, thus altering the turbochargers' peak boost point and adding to the perception of lag. Currently all performance degradation discussion has been based on seat of the pants feel, along with increased exhaust noise and fuel consumption. Despite the claims, BMW North America and service centers have, thus far, found no critical issue with the new settings. If owners want to present true evidence, they should use a simple OBD scanner device to data log the manifold pressure or simply run a dyno comparison test. Thanks for the tip everyone!

Now that leasing seems to be going through a slow phase-out, shoppers looking for a good deal on a newish vehicle may take a harder gander at certified pre-owned models. GM realizes this and has responded by ambushing customers increasing the warranty coverage on the CPO models for all of its brands, minus Cadillac which has its own program. The new warranty stands at 12-months or 12,000 miles and begins when the CPO purchase is made -- an increase of up to nine-months over the previous guarantee. Being a "bumper-to-bumper" warranty, everything excluding wear items like tires and brakes are covered for manufacturing defects. The powertrain warranty remains: five years or 100,000 miles from when it was sold as new.

GM hopes that this increased coverage has a corresponding effect on its CPO sales. What's more, the automaker also believes that this action will have a desirable effect on its vehicle's residual values.

Remember last week when we told you about a tuner shop in Florida that got stuck holding a $16,000 bill after customizing some broke guy's Toyota Celica? That shop is resolving its dispute through the courts and will likely end up selling the car to make its money back, but a mechanic in the U.K. named Darren Tandy recently found himself in a similar situation with a very different outcome. A customer came to pick up his Land Rover recently and refused to pay the agreed upon price of £1127 for the service work that Darren had done. At first the owner offered £950, then £850, and when Darren still refused to release his vehicle, the Rover owner called the local constabulary. Shockingly, the policeman who arrived on the scene actually told Darren he had to lower the price, and when he refused to accept £550 for the job, which didn't even cover the parts, he was arrested and thrown in jail. He spent three hours behind bars and promptly filed a complaint against the Northumbria Police, who performed a full investigation and found themselves free of any wrongdoing. Convenient, eh?

J.D. Power and Associates has just released its 2008 Vehicle Dependability Study that attempts to measure vehicle quality throughout the first three years of owning a vehicle, and for the 14th year in a row Lexus leads all manufacturers with a rating of just 120 problems per 100 vehicles (PP100). This year's runner up, surprisingly, is Mercury, though it's a distant second at 151 PP100. Cadillac (155 PP100), Toyota (159 PP100) and Acura (160 PP100) round out the top five spots for brands. Lexus also had the most segment leaders with six vehicles leading their respective category, while Toyota tacked on another five. The study also says that long-term vehicle quality has also improved 5% across the industry in 2008, with the industry average dropping 10 PP100 down to 206 this year.

The Vehicle Dependability Study is based on surveys taken of 52,000 original owners of 2005 model year vehicles. Take whatever stock you will in it, as some argue that subjectivity can skew the results. For instance, Lexus owners may tend to report that their vehicles are running just fine out of pride and loyalty to their brand. Nevertheless, J.D. Power's complete press release and results for the industry and each segment category can be found after the jump and in the gallery below.

A wealthy Arab man, thought to be a Sheikh, recently had his black and gold Lamborghini LP640 flown 3,250 miles to London via Qatar Airways and trucked to a certified UK Lamborghini dealership last Friday for a fluid change, which cost him a paltry £3,552 compared to the £20,000 round-trip flight. That's a grand total of £23,552 ($46,644 USD) for a friggin' oil change.

Environmentalists are obviously not pleased with the owner's wanton display of conspicuous consumption. Airport workers at Heathrow also blasted the owner's excess after watching the car get the royal treatment on the runway. One commented, "This car doesn't have a carbon footprint - more of a crater," and another pointed out that it would've been much cheaper to just fly certified Lamborghini technicians to Qatar to do the service.

This type of behavior begs the question of how far one's personal choice extends in the face of the greater good. We're told the Earth is dying beneath our feet and it's all our fault, so should a Sheikh be allowed to ship his car around the world for an oil change while the rest of us stick compact flourescent light bulbs in our lamps and wait in line to buy a Prius? Perhaps the only act that could be more environmentally egregious than this is if he just threw out his exotic and bought a new one every 3,000 miles.
