So I was talking with an independent (non stealership) auto mechanic about my 2000 Polo and told him what a lovely little car it was with a cute little 999cc engine and telling him how good it ran now that I've chucked away about half a ton of plastic and hoses from under the bonnet and he assured me that there's pretty much no chance this car would ever pass it's next MOT because it would fail on emissions even if the engine were brand new as the factory made it because the new MOT rules are basically designed to fail all cars more than an hour and a half old so you're forced to either buy a new car or do without. After discussing the pitfalls of idiotic, incorrect and pointless emissions regulations like those foisted upon us by the drunken unelected fools of the EU I went away feeling pissed off that the first car I've bought in twenty-odd years was probably just money down the drain as I'd have to throw it away by next year's MOT even though it ran fine. But that got me thinking about some things. Firstly, I know little of, and care even less about, the science and regulations of modern exhaust emissions but it occurred to me that if a slightly knackered catalytic converter not doing it's job well enough could fail the MOT when nothing else was even wrong with the car then in theory why couldn't you just fit two (or five or ten...) catalytic converters in the exhaust train of your car sequentially so that at MOT time all that came out of your exhaust was fairy giggles and bunny smiles? You could have two exhausts, one made of catalytic converters you fitted once a year for the MOT and a sensible one for real life. Or how about running bioethanol instead of petrol for the MOT? An enine's an engine and it's not rocket science. They CAN be made to run on a wide range of burny fluids. I've even run a two stroke bike on white spirit and got a 50cc engine to fire up on vodka. In most older engines alcohol or propane will work without much alteration to the carbs, so has anybody tried running a fuel injection engine on something other than Morrison's best supermarket petrol? Just wondering. It strikes me that having cars run on petrol and then making the emissions rules so strict it renders them illegal is pointless and unnecessary. So, two cats or not two cats? That is the question. Or how about fitting an enormous bag like a hot air balloon clamped onto your exhaust during the MOT so there's no emissions whatsoever "when tested"?
Hey all, I have a 2002 VW polo 3 door 1.2l (65bhp model with AZQ engine). I think the check engine light is on but the lamp has either been removed or burnt out. The exhaust smells like fuel and the fuel economy is rubbish, it is also quite slow to pick up. The engine also sounds a bit airy - someone told me that there may be a leak in the exhaust from the way it sounds. My friend did a scan with the vagcom software and this is the result I think the pre cat o2 sensor may be faulty from some research I have done, I bought a cheap OBDII scanner and im trying to find an app to show me a voltage graph to see if it is pulsating as it should. Am i on the right track? Anyone have any advice? I am really hoping it is just the o2 sensor and not the catalytic converter...
