emissions

My car has just had the downstream O2 sensor renewed as STAR said it had failed its test but the upstream was okay. Just got back from the MOT and it failed on the fast idle test with: CO 1.4 and 1.08% Lambda 0.959 and 0.967 The natural idle was 0.49% so just passed. Any pointers from you...

Just had my R129 fail the MOT on emissions after the secondary cat delete I had done in April. Car has done under 700 miles since the previous MOT, which was fine. Luckily I'd put it in early just in case - I've got till the end of the month to get it sorted. I've not heard of anyone else...

Will a de-DPF'd (cat to petrol types) pass a 1998 type MOT emissions test, assuming its still basically running ok?

Grrrrr. On the first attempt, the emissions were very high - subsequently explained by the lack of a catalytic converter in the system (how on Earth do you get a car that's had its cat removed through an MOT?!). I've rectified that, but now the emissions on the fast idle test come in only just...

BBC News - 'Carmakers manipulate emissions tests' Didn't we already know this?

Was just looking at the price of road tax and wondering what tax band my car would be in under the post March 2001 classification. I have an E280 estate 1999. Any ideas?

Hi all Mate of mine has a vito petrol. Failed MOT on emissions too high in all four segments of tests. I checked the plugs and airfilter, both recent. It seems to run a bit "choky" ish, only used for short journeys. I forgot to tell him to go for an italian tune up before the test but I do...

Hmm, MOT failure last friday on emissions (0.4% rather than 0.20 Max. . .) so the guys say I need new Cats. MB price is horrendous. Anyone know a custom cat supplier, or even after-market for a C32? I'm assuming C320 doesn't fit. . .? I'm not necessarily terrified by the thought of custom...

After having it looked at this week it seems my car has a crack in the seal of the drivers side manifold inlet, the car has only done 66k miles and it seems to be something that just shouldntbe failing, after searching and reading various posts on US forums there have been a few other instances...

Hi, my hearse failed the mot yesterday on the emissions, just wondering how I could solve the problem?

Hi, I am new to this forum. I live in Sweden and this is my first MB. I have got a E270 CDI 2003 (w210) diesel engine that did not pass the MOT due to high emissions. Should I change some filters? Should I run it with an injection cleaner or do you have any other solution to my problem? I...

Took my W124 for MOT yesterday and it failed on emissions BADLY. Here's the list: 1. Exhaust emissions carbon monoxide content after 2nd fast idle excessive 2. Exhaust emissions hydrocarbon content after 2nd fast idle excessive 3. Exhaust emissions Lambda reading after 2nd fast idle outside...

420 SEL failed MoT on emissions. Described as "minor, just needs adjustment", no figures given. How can this be rectified? Have been advised the mixture is adjusted thru' the air cleaner, is this right and if so what adjustment will give the desired effect ie MoT pass? Hoping someone out...

Not pointing anywhere in particular but I've recently found a couple of websites that put my W203 C230 Evo Panorama (auto) CO2 emissions at 222 g/km - the DLVA Road Tax calculator puts it at 229 g/km. Can anyone tell me which is correct - because it's possible I'm paying too much road tax...

Bureaucrats are hell-bent on reducing car emissions to the point of absurdity, and in the process forcing manufacturers to produce marginally reliable cars that are expensive to fully develop/test and for the owner to maintain/repair. Toyota and Honda are recent casualties in this process which...

Have I got something wrong? I understand that one liter of petrol weighs 0.72 kg. I also understand that 1 liter of petrol gives off 2.33 kg of Carbon in emissions. Are these figures correct and if so can someone explain the physics of that?
