Thread: VW caught by the Yanks for breaking emission laws

And if it didnt think it did the DPF burn correctly then it stuck into limp home mode and you had, to quote one owner, "About as much power as fozzy."

The logic I was quoted was that while the engine was in warm up there was no requirement for it to pass emissions as the emissions tests were specified for the engine at normal operating temperature.

We are talking about brand new modern vehicles that actually go,not some heap of **** coaster,and yes I have unfortunately spent many hours behind the wheel of Toyota's mighty Coaster van,and many more swearing at the heaps of **** when the boat anchor 1HZ's and 3B's or what ever they were called overheated,It took Hino repowering before coasters got enough welly to safely overtake mobility scooters or a kid on a BMX.

See for example the discussion here about torque

I found it researching a totally different topic,the Audi and VW were 4 times over the allowed level,BMW-Merc etc were 5 times give or take and the Mazda was 14 times,thats one four times over the allowed limit,where's MIck . I would love to see it done here,I would pay to see Nissan and Toyota's results as well as Land Rovers. Pat

Sooooooo Pat
You are saying that no-one can keep to a mandated limit
Soooooo either the limits are shiite or the vehicle manufacturers are having a lend saying that they "meet limits"

I can guarantee you that the money will be that the manufacturers will have to change not the limits

VW will be up to their necks in it but only just next to the other makers

Who exactly was it that let the manufacturers tell the regulators they meet the limits?

I can see all emission control will be up for an overview in the next 12-24 months

I was actually talking about 2010-11 models which, if I recall correctly, also covers the same year group as some of the VW vehicles that are suspect, but if thats not modern enough for you, would a G wagon be modern enough for you?

same thing, try holding one of those up just under the limiter with a full load on when it decides that it needs to clear the DPF.

The last one I drove was a late model,I can't remember feeling the loss of power,even the Isuzu's which had chronic DPF and EGR problems still drove normally until they dropped into limp mode,I'd say there was bigger issue's at hand. Pat

You need to remember that emissions tests like economy tests are done under controlled conditions,not under real world conditions,the fact that VAG,Ford,Merc,BMW,Mazda etc all failed means that yes when driven on the road in real world conditions all the cars failed the emission tests.A bit more digging and Euro 6 vehicles like the Ford Focus have also failed the real world test.

Rereading this,your talking about a separate thing all together,if the DPF needs to burn off it will reduce power,thats because the filter itself is choked up and needs to clear itself,the motor actually pumps raw diesel down the exhaust to the DPF to burn off the particulates,all of that will happen to any vehicle if it's driven short distances,normally a light comes on telling you to drive for another 20 minutes or so.
