RECALL

FLASH OF DEATH

The Volkswagen emissions scandal has hardly died down, when we heard that Volkswagen is in the dog box once again. The German car giant is in the process of 

'recalling  as many as 3 million 

Volkswagen's, Audi's, Seats 

and Skoda's  worldwide'

due to DSG (direct-shift gearbox) "gearbox problems" that causes loss of power. This is probably one of the biggest recalls in VW's history. Though in comparison  to Toyota's recall of 10 million cars between 2009 and 2010, amid accident fears over sticky accelerator pedals and floor mats, Volkswagen’s recall is but minuscule.  Some believe that the Volkswagen  recall is  bogus. But it's really good to see that Volkswagen is "stepping up to the plate". 

VOLKSWAGEN RECALL

The recall reports that the dreaded 7-dry DSG malfunctions are the result of faulty "temperature sensors" (NTC - thermister) caused by the use of synthetic oil in 7-speed dual-clutch gearboxes.  As such synthetic oil will be replaced with traditional mineral oil. Somehow the Audi 2L TFSI models, the Golf GTI's with the 6-wet DSG and the reliable Tiptronic A/T  are not affected. But that doesn't mean that the wet DSG's are not totally immune to mechatronic failure in the future.  Jetta SportsWagen, GTI and Eos vehicles built between September 2008 and August 2009 and a limited number of 2010 Jetta seem to be most affected. It was probably a bad batch of DSG's.

One is the "false neutral syndrome" where the flashing PRNDS occurs with the car losing all motive power without warning, (traced to a faulty DSG heat/temperature sensor) and the other is where the DSG (direct-shift gearbox; German:- Direkt-Schalt-Getriebe) suffers severe delays at shift points, causing erratic shifting, jerking, long stall pauses, clutch slipping, surging in forward and reverse, etc. 

The "gearbox problem" previously mentioned is non other than the "Flash of Death" aka "DSG Flash of Death" aka "false neutral syndrome", resulting in  a flashing PRNDS. When this happens,  the car loses all motive power without warning, as its transmission goes into limp mode by selecting  3rd gear. But this isn't always the case because subject to the actual "gearbox problem", because the transmission may not disengage. So when the engine is switched off, it may not start thereafter. A second transmission problem revolves around causing erratic shifting, jerking, severe delays at shift points, clutch slipping, surging in both forward and reverse. This  often happens when accelerating, overtaking  or cruising and your VW or Audi is also prone to slip gears and judder at low speeds, even though clutch adaptation may have been done. These faults have been associated with the Mechatronic Unit, bent clutch forks and warped clutch packs. If you have vag-com, you will see that your car threw one or more of the following DTC's, or a variation of them.

MECHATRONIC UNIT

Long story short, your VW or Audi is more likely than not going to need a mechatronic replacement when you experience the above. However, that doesn't mean every transmission problem can be solved by replacing the mechartonic unit.  I know of someone who experienced the "VW DSG Flash of Death". So, he took his Audi to the VW service agents who diagnosed a faulty Mechtronic unit and a faulty wiring harness. Charged him $3500 for parts and labour and three weeks later, "DSG Flash of Death" struck again. The peculiar thing about the "DSG Flash of Death" is that it affects  brand new vehicles. Cars with as little as 3K kilometers on the clock and virtually none of them exceeding 50K on the clock before the DSG (Dreaded Spiteful Genie / direct-shift gearbox) takes revenge. But a faulty mechatronic unit isn't the only problem Volkswagen is facing. Some 30,000 Volkswagen Tiguans are being recalled in the UK alone because of an intermittent fuse / blown fuse problem that causes headlights to cut out. 

The amount of transmission complaints that NHTSA received prompted their lawyers to get Volkswagen to initiate the recall. 
Be that as it may, VW and Audi branded cars sport really great technology, engineering and performance as well as beautiful aesthetics, but what good is all that if the darned car leaves you stranded every so often, costs a bundle to repair and maintain, besides the darn thing can kills you, when limp mode kicks in on the freeway, with fast flowing traffic on your tail.

OTHER VEHICLE RECALLS

Recalls are common in the motor industry but getting the incumbent to take responsible can be a painful as pulling teeth. Recalls are also as common as sand and by the looks of things,  no auto manufacturer is except.  For example, Ford Kuga SUV fire recall goes all the way back to 2013 in South Africa. Now, they are  in the process recalling thousands of its Kuga (fireball) models following client reports that the SUVs self-combusts.  

Honda is recalling an  additional 775 000 vehicles for defective front passenger airbag inflators that was manufactured by the Japanese supplier Takata.

Toyota is globally recalling all the Mirai fuel-cell vehicles  due to a software bug that can shut off its hydrogen-powered system without warning. Toyota is  also recalling more than 300 000 hybrid Prius vehicles globally due to a defect in their parking brakes. 

Volkswagen will recall an additional 50 000 vehicles in China due to brake problems when the cruise control is activated. 

BMW is recalling some 150 000 cars and SUVs in the US and Canada due to wiring problem to the fuel pumps inside the gas that can cause its engines to suddenly stall.

Mazda is recalling almost 175 000 cars in the US due to the seats can suddenly change angles, making driving difficult.


And the list goes on.
