IAT makes no difference unless it reports temperature above 55 degrees when it retards the ignition timing. Every one I've ever checked has always read low, mine always shows about 10-12 degrees below ambient. Unlike Super4 in Spain who was suffering from a lack of power in hot weather and it turned out that his IAT was reading high so it was backing off the timing (he's now goit a 1k Ohm resistor in place or the IAT which makes it think it is cooler). Low idle could be down to a rich mixture, although normally that will be corrected by the IACV opening up to get the idle correct by adding more air. What is shown by the Nano as the idle figure as 625 rings a bell with me and not 700 like RAVE says it should be. When idling, have a look at the IACV opening. It should be around 20-30 when warm. At idle what does the fuelling display tell you, is it showing CL by Lambda or Open Loop?

Having done an awful lot of research into this in the last few weeks for work, I can answer all questions. As our resident petrolhead, I've been tasked with identifying what vehicles we replace our current fleet with, and believe me, it isn't simple....

As far as the Congestion Charge goes, that is quite simple. You can apply for an exemption (and pay a one-off £10 fee) if the vehicle is Euro 6 petrol or diesel and is capable of at least 20 miles at zero emissions. That means it MUST be either full electric, hydrogen or plug-in hybrid. We've got an office within the CC zone with a pool car kept there. That one will be replaced with a plug-in as currently it cops for the CC every time it leaves the office car park so is costing around £150 a month on CC alone..

The French and German schemes go on date of registration, rather than Euro figure stated on the V5 or equivalent (although they coincide with the introduction dates for the various Euro standards) and type of fuel. A gas powered vehicle automatically gets the same classification as a plug-in hybrid, see https://www.lez-france.fr/en/information-about-the-critair-vignette/the-french-vignette-critair/who-will-get-which-critair-colours.html. That's why I've got Classe 1 on my P38 when if it was on petrol it would be Classe 3.

The next bit is conjecture but I understand from a mate who was considering buying a Jap import P38, that an import, as it doesn't have any emissions details on the V5, is automatically exempt from the ULEZ charge. Or at least it was when it was called the T Charge but it may now have changed. Easiest way to find out if that is still the case would be to put your registration number into the London ULEZ checker at https://tfl.gov.uk/modes/driving/check-your-vehicle-35896. While I don't drive into Central London in my car, it is proposed that the ULEZ will extend to all areas within the North and South Circular roads in late 2020. I keep meaning to write to TFL and see if they would consider an exemption for LPG powered vehicles. Using the French scheme as an example, the fact that there used to be the Powershift Register making LPG powered vehicles exempt from the CC (which I suspect was dropped as it only included a very tiny minority of vehicles) and Sadiq Khan offering grants to taxi drivers to convert, it has to be worth a try.

Having spent and awful lot of time recently research the whole fuel situation for a project to replace our fleet of vehicles, petrol will be around for a very long time yet. Other than a few 'mild hybrids' that use a combination of diesel and electric motors, all of the other plug-in and self charge hybrids use a petrol engine along with the electric motor(s).

Out of town emissions aren't even considered, hence the introduction of the DPF. When driven in an urban environment (which the emissions tests concentrate on), the particulates are stored so keeping the emissions down only to release them when travelling at speed. Which will invariably be out in the countryside.

Sadiq Khan is offering grants for London taxis to be converted to alternative fuel, including LPG, even though, unlike the other European countries that have introduced ULEZ zones, there is no concession here. I keep meaning to email TFL to ask why I'm not being offered an exemption when I'm classed the same as a hybrid in France, Germany, Belgium and Holland. Lets face it, there's 150,000 LPG cars out there according to DVLA yet if my experience with the 5 I've owned, only 1 was shown on the V5 as being dual fuel, so realistically there's probably around 500,000 of us. Compared with 230,000 electric vehicles registered with DVLA at the moment.

There's a couple of holes right at the back on either side that go into the area below the rear light units. One side will have the cable for the towbar electrics going through it (assuming you have a towbar), the other side will have a grommet.

Looking on the Island 4x4 site last night for something else, I noticed that they have both GEMS and Thor injectors in stock and the GEMS ones are actually cheaper.

No Dave, people go quiet because they are pissed off with your rantings. We are all aware of Climate Change, we are all aware that politicians will try to offer platitudes to keep the more vocal quiet, we are all aware that the emissions from motor vehicles have such a minuscule effect on climate change compared with other sources of greenhouse gases, we are also aware that even if a tiny country like the UK stopped all greenhouse gas emissions it would have absolutely no effect whatsoever.

I think the only thing we can do now to bring this to a close is to stop feeding the troll......

I don't know. Some faults are shown as Current, for example blend motors when checking the HEVAC, so even though you can clear them they will come straight back. Not sure I've seen a Permanent fault though.

When you read and clear faults with the Nano, the text of the fault code stays there unless you come out of that screen, go back in and read the faults again.

You want to get into politics, you seem unable to answer a straight question so you'd fit in fine......

Can I ask a simple question Dave? If you believe all of the, selectively researched, reports and consider that Greta is right, should not be ignored and we really must do something about it, WTF are you doing on a forum for owners of large, internal combustion engined, cars?

As said, there have been activists on numerous subjects over the years, some have affected things, others have grown up and realised they aren't going to change the world so have gone on to become normal members of society and just accepted things are the way they are. She may have made a few people think but she's never going to change the world. She's in the same category as the tin hat brigade, just she's managed to get a bit more exposure and credence.

and back on topic, zero emission by 2030, no bloody chance. Anyone that does even the smallest amount of research will realise that the amount of CO2 generated by motor vehicles is only a tiny percentage of that generated in total.

D1000 is just a series rather than an actual part number. From here http://users.erols.com/srweiss/tableifc.htm, it looks like the Bosch ones are 0-280-155-787. If you can find the actual part number for a Lucas GEMS injector, you can compare the specs.

I'm sure there's at least two members up in that neck of the woods but can't for the life of me think who they are...... I'm a bit closer than Rob but not by much.

Lrcat is Microcat only ripped off and hosted on a Russian site. Both Lrcat and Microcat both show ERR722 as up to VIN WA410481, so GEMS and ERR6600 as from VIN XA410482 so Bosch. having looked at the usual suppliers, there doesn't seem that much difference in price between either, all around £50 a pop.

EDIT: Immobiliser was showing "Disabled"

That just means passive immobilisation is disabled so it doesn't immobilise itself when you unlock it but don't start it within 30 seconds.

I wouldn't know if they are interchangeable but I do know that the O rings are a different size between GEMS and Thor, so I suspect that isn't the only difference. The Thor uses a higher fuel pressure too so I would suspect the flow rate is lower.

Go figure what? I'm not in the slightest threatened by a kid that has some ideas that the world is going to end and constantly screams that something must be done about it without actually having any answers to what should be done about it, other than changing the lifestyle, living conditions, eating habits and everything else we all take for granted. Christ, if she was old enough and experienced enough to have discovered sex, she'd probably want to ban that too. Think about it, all that heavy breathing generating extra CO2, the heat generated by two bodies raising the air temperature, not to mention the extra electricity needed to put the bedclothes in the washing machine.....

I feel as threatened by her as I do by the nutters that paper their living room walls with Baco foil to stop the radiation from a mobile mast half a mile away from frying their brains.

As Bolt has pointed out, she crossed the Atlantic in a boat that created zero emissions during the journey, while she conveniently ignores the huge carbon footprint and emissions generated in building it.

That's the problem when folks start thinking/acting differently of course, it upsets the Status Quo; If only The Beatles, Elton John etc etc had been made to conform more by their parents then the whole world would be a much better place ??!!

Whether they were made to conform or not isn't the point, it's whether they insisted their parents followed their own non-conformism. How many on here are parents? Most I would think, and how many of us have heard the cries that eating meat is cruel to animals, we should all become vegetarians. That lasts for a few days but they soon get bored of cooking their own meals while the parents tuck into steak and chips.

"Uniti uses steer by wire technology", now there's a recipe for disaster if ever I heard of one.......

On the subject of Greta, she's no different to the thousands of other kids that have thought they know better over the years. The only difference is that she's got the advantage of the internet to spread her words to thousands of other kids that think they also know better. It gets to a certain point where they can't be ignored. So she managed to convince her parents to become vegan and give up air travel, so causing her mother to give up her career? Just shows what a spoilt little brat she is if her parents take that much notice of her. In most families it would be a case of, "If you want to become vegan dear that's entirely up to you, but don't expect me to give up my life for your ideals".

No, not the BeCM, I was being facetious. Wipers will be RL8 or the wiper motor itself while the other two just need an aerosol.

(there are 2 in a GEMS, right? not sure which one I need to be worried about)

There's a green one and a grey one. The green one drives the gauge on the dash, the grey one supplies temperature information to the ECU. If you use the nano to show the coolant temperature, it will be taking the reading from the ECU, so the one that matters.
