Volkswagen under investigation over illegal software that masks pollution

[knightsy]

centralaxis's list (page 1 only mentioned the EA189 equipped vehicles. I thought I saw mentioned somewhere yesterday (can't remember where now) the EA288 engines (I have one in my 2015 build Golf TDI no?) are also affected. Can someone confirm this?

As for individual claims, I believe dyno testing documentation will help to assert any claim when viewed in conjunction with the body of evidence in the public domain.

Yeah, why not? You can believe in it.

I sure do! Now back to making my tin foil hat.......

My memory is the EA288 is Euro6 compliant, so not affected.

Looked at the bad exhaust pipiing in the WVU study:

Can compute pressure loss with a formula like this.
Air Duct Components and Minor Loss Coefficients

Pressure varies with v-squared, so a lot worse with high exhaust velocities. The loss coefficient for different bends is in the table. Compare factor of 1.3 for 90deg bend (VWs) with 0 for tapered reduction (BMW).

Also looks like the VW with single exhaust had the same bad pipe as double exhaust with one side just blocked off. This would induce resonant chamber effects as well as screwing up flow.

came across this on FB today

Haha.... champion!

Reading further Minor Loss in Pipe or Duct Components

The minor loss coefficient - ξ - ranges values from 0 and upwards. For ξ = 0 the minor loss is zero and for ξ = 1 the minor loss is equal to the dynamic pressure or head. The minor loss coefficient can also be greater than 1 for some components.

A right angle join (1.3) has a loss greater than the forward pressure! I wonder if this factor accounts for reflection or do reflected pressure waves count more negative effects?

For what it is worth a media release from the ACCC

On a personal note, I have booked our Passat into the dealer for a service. This will buy us some time to assess the recall
