BS20 Posted January 29, 2020 Share Posted January 29, 2020 2005 2.2 HDI Peugeot Boxer 23,000 miles passed MOT today with one advisory. 'Emissions too clean to register'. Am I missing something as I thought that low emissions are a good thing. If so why an advisory. The engine was hot when I drove in as I had done 15 miles on the motorway beforehand, Link to comment Share on other sites More sharing options...
paul2 Posted January 29, 2020 Share Posted January 29, 2020 Hi It just means the engine runs so clean it does not regester went doing the emissions test, so tester put it down to cover him self to show he has tested it. Paul Link to comment Share on other sites More sharing options...
hallii Posted January 29, 2020 Share Posted January 29, 2020 I cannot believe that the engine emissions are that clean, it's a diesel so there must be SOME emissions. Maybe his machine was faulty. Anyway, a pass is a pass. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted January 29, 2020 Share Posted January 29, 2020 There are plenty of on-line comments about this. It’s touched on in the MOT Inspection Manual that says: Maximum engine revs cannot be achieved on some vehicles due to design features. If this is the case, the vehicle must be tested as presented. Such vehicles, as well as some with low emission diesel engines (mainly Euro IV and onwards) may fail to trigger a reading on the Diesel Smoke Meter (DSM). If you cannot get a reading or the DSM shows an error, you should mark the printout to show that the emissions limits were tested and met but the DSM could not register the reading. If you cannot print out the results from the meter, write down the following details and keep them for 3 months: test station number tester’s name date and time test number vehicle type vehicle registration number that the vehicle passed the emissions test no print out was produced due to low emissions Link to comment Share on other sites More sharing options...
BruceM Posted January 29, 2020 Share Posted January 29, 2020 Derek Uzzell - 2020-01-29 5:22 PM If you cannot get a reading or the DSM shows an error, you should mark the printout to show that the emissions limits were tested and met but the DSM could not register the reading. no print out was produced due to low emissions But there’s no suggestion that it should be marked as an MOT advisory. I’ve had this occur on my car before. When this has happened it’s been marked on the emissions test print out as above but the MOT is given as a pass with no advisories.

niktam Posted January 29, 2020 Share Posted January 29, 2020 Similar topic! Took my V70 in for the 2nd MOT not even run in at 150,000 miles it failed on emissions. It turned out it was left outside for some time before being tested and wasn't fully warmed when they tested it. I then took it to the Volvo dealer who said that they had never?? had an emissions MOT failure. They clearly made sure it was fully warmed up before the test and it passed. In future I will only book an MOT for a specific time and wait to take the vehicle in nice and warm unless we move on to electric powered. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted January 30, 2020 Share Posted January 30, 2020 As I said above there is a good deal of on-line discussion about this, including queries from MOT-test inspectors on what should be recorded and how/where the record should be made. https://tinyurl.com/w6lsn9n Provided that the vehicle owner understands that the ‘emissions too clean/low’ comment does not mean that there is a fault with the vehicle itself, I would have thought that the comment appearing on the MOT-test certificate is harmless even if it is shown as an advisory-notice. (If anything appeared on a MOT-test certificate for my vehicles and I did not understand what the comment/advisory-notice meant, I’d ask the MOT-test station for an explanation.)

Brian Kirby Posted January 30, 2020 Share Posted January 30, 2020 FWIW, my interpretation of a similar advisory in 2017 was a) that the lack of a reading was good news i.e. a very clean exhaust, and b) that I was being informed accordingly - hence the "advisory" note. OTOH, if the advisory had been that the exhaust emissions were only just below the fail level, that would be a different matter. Reminds me of a Marty Feldman sketch from some years back. Marty was an airline pilot. He switched on the P/A and announced "Ladies and gentlemen, there is nothing to worry about". Then switched off the P/A. Result - chaos! Perhaps your tester was the shade of Marty Feldman! :-D Link to comment Share on other sites More sharing options...

breakaleg Posted January 31, 2020 Share Posted January 31, 2020 Or, as experienced on a cruise last year in the middle of the ocean just after two am Ladies and gentlemen, we have a situation on level five in the engine room, the situation is fire. Then nothing for ten minutes , when the Captain came on and told us it was a faulty censor, bang go's another nights sleep. lol. Next day a seasoned cruiser said that you shouldn't worry as worse things happen at sea, not exactly sure where she was. lol Pete Link to comment Share on other sites More sharing options...
Paul- Posted January 31, 2020 Share Posted January 31, 2020 I use premium diesel and synthetic oil as recommended and get a negative reading every year, the only comment I get is "I bet you don't use supermarket diesel". Link to comment Share on other sites More sharing options...

A cruise ship taking on water, passengers and staff waiting for a command that never came. Some members of the cruise ships band went to the bridge only to find it deserted! One guy fiddles around with the radio and eventually figures how to work it. "Mayday Mayday Mayday this is the SS Whatever and we're sinking" Rescue reply; "Please give your co-ordinates Captain". SS Whatever; "i'm not the Captain.....i'm a guitarist in a band" Rescue reply (now shouting angrily); "Why are you on the bridge....get me the Captain immediately and get off that bridge" SS Whatever; "I can't....the Captain has abandoned the ship" The radio call exchange is on YouTube and all were safely rescued.
