The Breakdown: getting your head around the Volkswagen scandal

6 October, 2015

We’d all love to be able to pick up the newspaper every morning and have a leisurely read with a cup of coffee and our bowl of weetbix, and of course we’d love to explore some of those headline stories in a bit more depth — but who’s got that much free time? Here at The Motorhood, we do the time-consuming hard yards and delve deeper into the goings on around the world to bring you the essential pieces of information from the big news stories so you can be informed and contribute towards the chats during smoko or around the watercooler.

The big topic that’s been a focal point since September is the Volkswagen emission cheating debacle — and we get back to basics so you can absorb the essential details.

What’s the deal?

Well, back in early September 2015, the US Environmental Protection Agency (EPA) presented Volkswagen with a Notice of Violation, alleging that the company included software in their diesel vehicles (in models from 2009–’15) that would allow the vehicles to pass the test that the EPA has in place to ensure vehicles are abiding by the emission standards.

Volkswagon have admitted to this, saying that there are 11 million vehicles worldwide that have the software, dubbed the ‘defeat device’, incorporated into the vehicle.

How does the ‘defeat device’ work?

It’s not something that can just be turned off as the EPA says that it “is embedded into the software code that runs the engine control computer”. It’s a program that recognizes if the car is being driven under test conditions and will perform in a way that will pass the EPA emissions test requirements.

Could this affect me?

According to Volkswagen New Zealand’s website, six per cent of the 75,000 Volkswagen vehicles on New Zealand roads are affected by the software — it’s been confirmed by Volkswagen AG in Germany that a total of 4639 vehicles in New Zealand are affected.

The specific models included in this are the four-cylinder TDI diesel Volkswagens including:

2009–’15 Tiguan 2.0 TDI (1411 vehicles)
2009–’15 Passat B7(1357 vehicles) — this excludes the new Passat B8 launched in May 2015
2009–’13 Golf 1.6 TDI and 2.0 TDI (680 vehicles) — this excludes the new Golf 7 launched in February 2013
2011–’15 Caddy 1.6 TDI (312 vehicles)
2011 Polo 1.6 TDI (2 vehicles)
2013 Sharan 2.0 TDI (2 vehicles)
2011 Touran 2.0 TDI (1 vehicle)
2011–’12 Amarok 2.0 TDI 90kW and 120kW (874 vehicles) — excludes current Amarok 132kW TDI.

If you think that your car may be affected, you can check to see for yourself on Volkswagen’s website where there is now an area to enter your vehicle identification number (VIN). The website can be found here.

How did it happen?

The Wall Street Journal said that there are two Volkswagen engineers that are being investigated closely — Ulrich Hackenberg and Wolfgang Hatz. They were among the engineers suspended when the investigation came to light. It is suggested that the engineers discovered they were unable to produce the clean diesel engine for the US market and created the software to mask the emissions when undergoing tests.

What’s happening next?

The German Volkswagen team are currently exploring technical solutions and will be presenting their action plan to correct the emission output before the end of October 2015.

Mitsubishi’s secret weapon

Ewen’s Starion is a little different and special. He saved this one – literally ‘found in a paddock’ — just in time, as he relates.
“Mine is a 1983 Starion. I’ve had it about five years. I first saw it in a paddock at Ryal Bush [north of Invercargill], and I went past it three times. The third time I went back and knocked at the door, but the owner didn’t want to sell. He rang up a year later, and put a price on it, which we accepted. Only thing wrong was the motor was totally dismantled.”
Ewen then set about getting the car back to its current state.
“It took me six months to find somebody suitable to refurbish it back then. Simon Bradley at Midas in Invercargill offered to do it and he did a great job on it. The head was badly damaged around the valves, and Simon said you could get generic cylinder heads now, so he installed one, and it cost $800. It’s made such a difference to the car. Mine is an intercooled, fuel-injected turbo model, fitted with a five-speed manual gearbox. It’s a great car to drive too.”
Except for a small patch of surface rust, Ewen’s car was in surprisingly good condition despite its paddock life.

Coaching from the bench: Casting plastic knobs and rubber parts

16 July, 2026

Casting rubber items is simple if you have a good original to work with. The item doesn’t have to be perfect. You can use plasticine to smooth out cracks, and you can even make whole prototypes out of low-fire modelling clay available from craft stores if you need to. Prototypes can also be made of wood or metal.
You will need mould dams to contain the liquid urethane moulding solution until it cures. You can build boxes out of strips of wood, but I have found that small plastic boxes and bowls such as those you would use for leftovers in your fridge work well if you spray them with a mould release agent.
Temperature is important to the chemical processes involved, so work in an area that can be maintained at around 20 degrees. You will also need adequate ventilation because the fumes can be dangerous to breathe. And you will want to wear latex gloves to protect your hands.
