VW scandal rocks the industry – do you still trust car makers?

Heather- Harcus Sinclair is the name of the company you are looking for , It is up to you whether you accept their T+C,s which ,with admin. fees could amount to about 50 % of your payout . This firm is a business orientated firm and not a “normal ” public law company I am not personally advising you on taking up their “offer ” it is entirely up to you . Others might feel different let them be judged on that.

“Should not have changed Tom” not according to 100,s of posters on Which and elsewhere but I admire your optimism , keep us informed over the weeks ahead.

Thanks for that George , while many have had the opposite effect your car seems to benefit from it , logic states that you must have had the work done at an extremely good garage in more ways than one (extra tinkering with the performance curve over and above the “standard ” tuning ) .

In my experience with my Golf 1.6tdi and other diesel cars, ambient temperature makes a big difference in fuel economy, especially on short and medium journeys, so hopefully this could be a factor in the difference you are seeing. It has been very cold here since Christmas. Mine goes in for modification soon and I’m encouraged that you have seen positive effects as well as the negative ones, George.

There is no doubt that nitrogen oxides are harmful to human health and city centres are the biggest concern. Carbon dioxide is produced by many sources.

I will post my findings and will be interested to know how your Golf does once the weather warms up, but I’m expecting some loss of fuel economy, whatever VW claim.

I’m booked in tomorrow. 🙁 The dealer has said that they will sort out any problems free of charge but I need to get this in writing. I’m hoping you have just been unlucky, Deborah.

Keep us informed Wavechange .

I would recommend you check out Honest John and Hypermiler before you take it in. There is a rapidly growing group on FB of people who have had issues with faulty EGR valves, increased DPF regenerations, reduced mpg, loss of power and injector problems post fix.

Thanks for the information Deborah. So far I seem to be lucky. I had planned to test the car on a decent length of dual carriageway on the way home but it is currently restricted to 50 mph. 🙁

The only really obvious change is that in neutral there is now a very brief increase in idling speed when the clutch is released. Trying to spot other changes, I suspect it may be able to run at a lower speed in the high gears without changing down, but that might be my imagination.

My car has done less that 39k miles and so far I have not had any problem with the EGR valve yet, but I’m well aware that this is a common problem with modern diesels. It’s hardly surprising when exhaust soot is fed back into the engine.

I asked if the dealership had found any problems and was told that a couple of Polos had to be looked at a second time because of increased noise. I will report back when I have an idea of whether the fuel economy has suffered.

@duncan-lucas – You asked me to report back. As I said in another Conversation, my car seems fine since the modification and I have not seen an reduction in mpg so far. VW have still betrayed my trust and if they they want to regain it they should make a sizeable contribution to healthcare in the UK to compensate for the damage their vehicles have caused to the health of our nation.

EGR valves do get clogged and need cleaning or replacing.

And I think the government should think long and hard before abandoning some railway electrification schemes and stopping short on others. We have the upcoming nonsense of electric passenger trains having to be retro-fitted with diesel engines to enable them to complete their journeys on many long distance routes. This will add weight to the trains, pollution to the atmosphere, filth to the maintenance depots, and noise to the station areas. When running under the wires, electric trains will be hauling an extra tonnage of diesel engines and fuel.

I agree with Duncan on the madness of successive governments trying to manipulate motor taxes for largely political reasons and ending up with little environmental benefit.

Personally, I stopped buying diesel cars several years ago. This was after a close colleague explained to me that he was an asthmatic and told me about the undesirable side effects of diesel particulate emissions.

What about commercial vehicles, public transport, taxis, diesel-powered plant…………………? There is a huge legacy of old higher-polluting vehicles, public and private. It would make much more sense to limit their access to towns and cities, think of limiting engine size, work hard on anti-pollution measures. Can you give a link to the government report where you say 37 diesel cars exceed the legal limit. Make sure this refers to the official EU’s NEDC test and not “on-the-road”, for which a legal limit does not exist.

The tail pipe of my diesel car shows no sign of soot after more than four years thanks to the particulate filter but I am aware that it still produces small particles of soot, which are believed to be more harmful than visible soot. I wonder if the answer is a high temperature catalytic converter, as fitted to petrol-engined cars.

Even if we never sold another diesel car, diesel engines are likely to be with us for many years, powering commercial and public transport, so it’s worth devoting effort to make diesels as clean as possible. It’s not so long since the engines of petrol cars were exhaling lead and a cocktail or carcinogenic chemicals. Three way catalytic converters removed most of the carcinogens and the lead had to go because it would have wrecked the catalytic converters.

These electrification problems seem to stem from people either unable to do their sums, or manipulating the numbers so the contract looks good – as in PFIs and, almost certainly HS2 – so when found out it has reached the point of no return.

We do need a real motor vehicle strategy, which is what I imagine you are alluding to John. Simply letting people pay to pollute might raise more money but will not help the environment. That strategy will need unpopular measures. As pollution is most serious in towns and cities, particularly I imagine around rush hours with high traffic numbers sitting in jams, controlling numbers would control the effects. But that would be unpopular with some, and would require a better public transport system and out-of-town parking.

Malcolm it was a government report published in April -2016 -the DoT found all of 37 top selling cars exceeding the the legal limit after testing for 90 minutes when driven on normal roads. As only MOT tests are a measure of legal judgment they were found NOT to have broken the law. As I know you always want 100 % verification then click on : https://www.gov.uk/government/news/government-publishes-findings-of-diesel-emissions-testing-preogramme

Thanks for the link duncan. I was only really querying whether these cars were “illegal” but, as there are no legal limits for on-the-road emissions (yet) , they would not be.

On the road emissions testing is starting this year and will lead to legal limits being imposed in the future (the Real Driving Emissions test)

Incidentally, if anyone wants to look at this report, delete the extra “e” in “preogramme” in the link.

The link begins “Vehicles tested in the UK programme showed no evidence of car manufacturers, apart from the VW Group, fitting devices to defeat the approved emissions test programme.”

It may well be the extra emissions controls come at a cost. It is for the EC (in this case) to set regulations and for manufacturers to abide by them. So perhaps we should ask the EC why they have not set lower emissions regulations. It may be some manufacturers do give lower emissions – the NEDC sets only a maximum level.

That’s what I assume, but surely there are enough people prepared to pay a little more for cleaner cars. I am disappointed that VED is based on carbon dioxide emissions rather than nitrogen oxides, particulates and other carcinogens.

“pay a little more for cleaner cars”. If the comments about domestic appliances are correct, many people seem unwilling to pay for more than they need. If we all had a social conscience, one way to reduce emissions is to stop driving older vehicles. But that won’t happen, we know.

I think concentrating on individual vehicle emissions is only sensible up to a point. The other factor that contributes to unacceptable pollution is the number of vehicles in an area – particularly a densely populated one – all at the same time – rush hour and traffic jams. We could deal with this straight away by introducing capacity limits, restricted vehicle access, providing we also ensure sensible alternatives are available – e.g. park and ride with acceptable charges.

Some of us are prepared to make an effort and I would have liked to have had the option of a cleaner version of my present car if that had been available at the time of purchase.

I agree that we cannot rely on individuals and legislation is the answer and that keeping cars out of city centres must be a priority. Park & ride is a sensible solution, and electric buses would be better. I don’t know how much park & ride costs across the country, but last week I paid £2 and tomorrow it will be £1 – substantially less expensive than city centre parking.

David are you noticing a reduced mileage and is your performance suffering ?? .An ERG vale takes your exhaust gases and pumps them back into engine intake to reduce the combustion chamber temperature .Its used to reduce of NOx emissions but it brings with it a sooty mess that gums up the EGR valve /EGR cooler/intake ports and any sensors associated with it . Try taking off the MAP sensor and checking it for soot -clean and re-install this will help performance . Legally they could go ahead with the conversion but due to re-mapping your engine might not run correctly ,if at all. The actual part is about £400 its seemingly a big job fitting it. Its a well known fault on VW Golf,s ,You Tube have a video on -DIY one performance company offer a kit to replace the EGR valve but only if there is no DPF filter installed , looking at spare part prices reminds me never to buy a VW Golf ,I will never complain of Ford spare prices again.

EGR valves become progressively blocked with soot and it sounds as if you will see the warning light soon. With some cars it’s possible to clean the valve and it’s not a major job. A friend had this done several times to his high mileage Ford before replacing it. I have a diesel Golf and from what I have read, its not a simple job and labour may be the main cost.

If the car has done a fairly low mileage, the main dealer may offer a goodwill contribution. If not, it might be cheaper to use an independent mechanic that is familiar with the task. Best of luck David, and please let us know the outcome.
