DonPeffers Posted October 2, 2015 Share Posted October 2, 2015 Euro 6 emissions limits came in September 2015. Auto Express magazine 24sep2015 stated the new Euro 6 regulations set different standards for petrol and diesel cars. For diesel cars, they dramatically drop the permitted level of NOx emitted down to a maximum of 80mg/km compared to the 180mg/km level that was required for cars to meet the previous Euro 5 emissions standards. The limit for NOx from petrol cars remains at 60mg/km, the same as for the Euro 5 standard. Greenpeace reckon, based on 11 million VW diesel cars affected then 1700 premature deaths a year due to increased risk of chronic diseases from air pollution; such as cardiovascular diseases and ischaemic heart disease from the NOx emissions.

dombanks Posted October 2, 2015 Share Posted October 2, 2015 are these vags then supposed to be euro 6 emissions? surely a car built and sold under the 5 standards wont have to meet the new standard? i'd like greenpeace to justify that claim with sound scientific evidence from peer reviewed sources.

Lawrie Posted October 2, 2015 Share Posted October 2, 2015 On the BBC, it said the cars withdrawn from the showrooms were Euro 5, being sold under a dispensation to get rid of old stock. So they must really kick out some smoke. The ecu switches to low NOX when the traction control section reports that the rear wheels aren't going round, but the rest of the car is doing 60.

Dave Eastwood (Gadgetman) - Club Chairman Posted October 2, 2015 Share Posted October 2, 2015 Wasn't it more sophisticated than that? Looking for specific patterns from the steering input as well as the traction control alongside the regular engine sensors. Quote Link to comment Share on other sites More sharing options...
dombanks Posted October 3, 2015 Share Posted October 3, 2015 Wasn't it more sophisticated than that? Looking for specific patterns from the steering input as well as the traction control alongside the regular engine sensors. There is a video on the web done by car throttle (in America) where they put a jetta on a rolling road I think they disconnect the traction but can't remember. using a 4wd run and then a 2wd run back to back they recon 15bhp and 30is ftlbs IRC between the two. Car obviously goes into some mode. Is this test a test that is done each year like our mot? Quote Link to comment Share on other sites More sharing options...

Dave Eastwood (Gadgetman) - Club Chairman Posted October 3, 2015 Share Posted October 3, 2015 If the dash is lit up like a Christmas tree, how is that a hidden/secret emissions test mode? That looked almost like the two wheel dyno put it into a limp home mode! (I had similar with a petrol 535 once, except as well as the lights, it's dash display actually gave you the limp home message). 2 Quote Link to comment Share on other sites More sharing options...

With an it's emissions tested, they would stop the testing if the car was showing warning lights. Quote Link to comment Share on other sites More sharing options...
stephenh Posted October 7, 2015 Share Posted October 7, 2015 Oh drat, it seems my Octavia was made after VW stopped doing whatever it was doing, so I probably wont get recalled for re-mapping. I was hoping to persuade my local Skoda dealer to down load the vRS map onto my engine control unit. Quote Link to comment Share on other sites More sharing options...
