Among other things I notice it doesn't use an air-air intercooler any more, rather a liquid water - air device. With a separate radiator to cool the water it uses. Now I know how my oil level sensing works on my Polo. Volkswagen has also stated that 11 million vehicles sold worldwide are affected in addition to thevehicles with 2.

Posted 25 September, The EA has been impacted by the software see attached on Wiki Posted 21 January, I presume the has the balancer shaft and the doesn't?
Having been in both I would guess it was the other way around.The conceptual study of the Yeti explored feasibility of a future series-produced vehicle, some solutions did not see production, including a single vertical windscreen wiper moving horizontally across the whole of the glass or horizontally divided hatchthe lower part of which was split into an inner and outer section so that two bicycles could safely be secured to the lowered outer section.
The car featured similar practical boxy design as the design study. Utilisation of interior was enhanced by the VarioFlex — the variable layout of the rear seats.
This feature was taken from the Roomster. There are three separate seats with adjustable backrest inclination covering a range of The possibility of folding down the backrest, and then folding the entire seat forwards, has not been changed. Once the seats have been folded over and forwards in this way, they can be removed by means of a simple release function.
The front passenger seat can be folded forward into a horizontal position to allow the transportation of long objects. The powertrain offerings in the Yeti included a range of internal combustion enginesall of which are four cylinder I4 four-stroke turbocharged  and EU5 emissions standard compliant.
Most engines were offered with six speed manual transmissions. The four-wheel drive variants utilised the fourth generation Haldex Traction multi plate clutch to transmit the drive to the rear wheels, and all drive layouts include fully independent multi link rear suspension  first seen on the Volkswagen Golf Mk5 to complement the fully independent front suspension.
A set of Off-Road functions included also a hill descent control, that used sensitive braking to maintain a constant speed descending steep slopes, regardless of whether the vehicle was in any of the gears from one to three, reverse, or neutral. The Yeti could be ordered with up to 9 airbags dual front, front side torso, rear side torso, side curtain, and driver's knee airbag. In most of Europe, the Yeti was available with three different trim levels : Experience, Ambition and Track  or Active in some markets.
An extensive list of standard and extras was available, incl. This design change also introduces a variable delayed throttle response and shuddering in first gear as "normal operation". A revamped version of the Yeti had its official exhibition premiere at the Frankfurt International Motor Show in September They varied also in the offer of wheel designs and upholstery. The technology had also been updated. Four wheel drive was powered by the fifth generation Haldex electro hydraulically controlled multi plate coupling located at the rear axle in the same housing as the final drive and rear differential.
The operating principle was much the same as the fourth generation used in the pre facelift previous model. There had been a technical change in the way oil pressure was regulated in the clutch, i. FWD switching. Oil pressure on the clutch plates was, after the facelift, regulated by a centrifugal valve integrated in the electric axial six piston oil pump.
Compared to the previous generation, the Haldex 5 system was 1. The drivetrain line up featured some new combinations: seven speed DSG with the 1. It is automatically activated when reverse gear is engaged: it displays the space behind the car and indicates the driving line, based on the vehicle width.
A special version of the Yeti was offered in China.Wolfsburg, Germany— Volkswagen's compact new turbodiesel engine is a gymnastics routine and a thousand science fair projects wrapped into some gorgeous aluminum castings. Called the EA by the men in tight-fitting, dull-colored suits who swarm this factory town, it shows just how far VW will go to meet emissions regulations in the United States and Canada in order to keep its sales leadership among diesel-powered cars.
While having seen two conflicting sets of sales figures, we understand the point: no other automaker comes close to providing as many diesels in the lands of the Stars and Stripes and the Maple Leaf.
Volkswagen Audi 1.4 TSI EA211 Engine Review
The VW diesel cult, which originated with the woefully slow Golf, demands its due. So the powertrain group led by Cambridge-educated Johannes Arning did the splits and then split the differences in order to meet the government's latest strictures on emissions. They faced a model year deadline to comply with ULEV LEVIII ratings, which are tough on the non-methane organic gases that are precursors of ozone and the oxides of nitrogen that prove so stubbornly persistent among waste gases.
The cc engine has a bore and stroke of Output is hp at rpm and lb-ft of torque between and rpm. The engineers' principal objective was to reduce cold-start emissions while improving efficiency. Technical development leader Thorsten Duesterdiek said it meant "putting a lot of money, a lot of effort in fulfilling the first forty, fifty seconds" of the emissions test. Duesterdiek seemed remarkably bright and upbeat after the ordeal, and he continued, "The most effective way is to put precious metals into the catalyst.
Besides a surfeit of palladium in the converter, a few other measures were taken in refining the new TDI engine. VW will make about 2.
In order to achieve the highest efficiencies of scale, the TDI engine must fit into both the smallest and largest vehicles. The improved EA version features reduced friction inside the cylinders; an oil pump with scrupulously controlled internal airflow; and a more compact head, thanks to a roller cam. To save energy, the water pump is as sensitive and variable as a peacekeeping force.
And the engine's thermal management system operates with three circuits governing cylinder head temperature, exhaust gas recirculation, and intake charge. The intercooler integrated into the intake manifold and the EGR unit with its own heat exchanger are designed for reduced pressure losses and improved responsiveness.
Just as VW has modular chassis architecture spreading through its car lineup, the EA is also modular. For example, the exhaust aftertreatment, which injects urea into the stream of waste gases to neutralize pollutants, can be tailored to suit the market. For example, Romania's emissions standards are far less NOx-crunching than Oregon's. Meanwhile, the EA must have a taste for low-sulphur fuel while also finding B20 biodiesel to be agreeable.
The EA will first be slid between the knees of the Volkswagen Golf when it appears this summer. Next it will go into the Jetta, Beetle, and Passat. The Golf SportWagen will return to the U. We expect the EA will not only meet its developers' targets for lower emissions and costs but also drivers' desires for increased performance and comfort.
We can't wait to test it for ourselves. In the interim, we have to settle for being highly impressed with the willingness of Arning's team to meet targets that would have seemed impossible when the Jetta TDI went on sale.
The American turbodiesel cult started then, and its growth is the amazing story of a special bond between a savvy manufacturer and its enthusiastic customers.Starting with the all-new TiguanVolkswagen's mainstream four-cylinder powerplant is being updated in the pursuit of improved fuel efficiency.
A modified version of the EA 2. The key update to this new 2. The shorter intake phase means a longer expansion phase. A higher geometric compression ratio is used to make up for the reduced intake stroke along with the benefit of decreased internal temperatures.
Variable valve timing on the intake camshaft adjusts valve openings depending on engine load, allowing for full power when needed and better efficiency at idle and under light load. Other significant changes include a modified cylinder head and a more responsive turbo.
This new 2. If you're wondering why Volkswagen didn't just apply the B-Cycle combustion process named after the engineer who invented it, Dr.

Ralph Budack to the existing 1. These changes actually reduce horsepower due to reduced volumetric efficiency, and less than hp would have been uncompetitive across the automotive landscape. So, the decision was made to apply the B-Cycle to the EA 2. The bigger engine is also better suited to higher loads, a concern when trends are moving more and more toward crossovers that are inherently heavier and less aerodynamic.
The lb-ft of torque in this engine is up 14 lb-ft from the outgoing Tiguan's but, as Volkswagen says, power is down from hp to hp. Also new for the Tiguan is an eight-speed automatic transmission.
We got the chance to drive in a pre-production Passat equipped with the new B-Cycle 2. The Passat is smoother off the line, less peaky, quieter, and max power arrives considerably earlier at 4, rpm rather than 6, rpm. That said, the 1.VW 2.0L TDI CJAA Timing belt Tricks!
Expect the new Tiguan, when it is EPA-rated, to hit 30 mpg on the highway and perhaps mpg city. The Volkswagen Tiguan will go on sale in late summer, with pricing to be announced in mid-June.

I've been reading about the differences for a year, but I'm still at an impasse. I was hoping for some input from the forums ahem Oilhammer to help me make my decision.
Balance shafts - I give this one to the EA The placement and design leads me to believe they will be more effective and reliable. Possibly easier to delete if necessary as they lack integration with the oil pump, unlike the EA Oil pump - I give this one to the EA for simplicity's sake.
Variable anything from VAG has taught me to be cautious. Vacuum and oil seems like a lot of work for that tiny belt to do for the "life" of the engine. Unless that "life" is at 62k and on the side of the road. Water pump - Another one for the EA for simplicity as well. I can certainly see a on the side of the road, overheated due to the damper getting stuck in the extended position.
Worse, some EA cars don't even have a coolant temperature gauge. Turbocharger - The EA in my Passat now has a warranty to k. The 's ends at 60k with the "lubricated parts" warranty. However, the in the Passat has an oil filter accessible from the top in a much more convenient place.
Fuel system - both use solenoid injectors and seem to be more resistant to failure compared to the piezo cousins. Fuel Efficiency - My experience is that the EA is much easier to make it to big mileage. The will do 48mpg, but it takes some work. The will do it if I simply drive slower than 75mph.List of Volkswagen Group diesel engines. The compression-ignition diesel engines listed below are currently [ when?
