  1. GT 1.9 MOT emissions failure

    Alfa 147, 156 & GT
    So, the Clover failed its emissions test today. Scored a 1.4 when the plate said it required 1.1 Do you think an additive would lower it enough? Also it failed because the system said it should have a DPF, but correct me if I’m wrong, GT’s never had DPF’s fitted in the U.K. It’s a 2009 1.9 GT...
  2. MOT Fail - Emissions - Help appreciated!

    Alfa Giulietta
    Morning all, I'm hoping that someone might be able to assist me... I've got a 2013 Giulietta 2.0JTDM 140. The car went for MOT yesterday and failed on emissions. It's since "passed", but I need to get the emissions sorted ASAP, or it will fail again next year and so on. For information...
  3. GT JTS exhaust mods and emissions

    Alfa 147, 156 & GT
    The exhaust on my gt has seen better days, particullary the middle silencer after the flexi. I've spoken with a buddy having the same motor, and he said something about the silencer being "catalyzed". That seemed weird to me, as the maniverter, I think, consists of all the emission regulating...
  4. German Co2 emissions per head double the average.

    General Motoring Discussion
    I just read this in a VW document “In Germany, the annual per capita CO2 emissions of 9.6 metric tons are twice the international average. In the EU climate package, the biggest emitter in Europe committed to its fellow EU member states to reduce greenhouse gas emissions by at least 40%...
  5. Emissions test failure

    Alfa 147, 156 & GT
    Hi, my 156 JTS has just failed the MOT on the emissions test. The garage reckons it probably needs a new cat. It's done 137,000 miles and to my knowledge has never had a cat replacement before. Given the attached test results, would you agree with the garage's recommendation? I'm a bit concerned...
  6. Fiat buys emissions offset from Tesla.

    General Motoring Discussion This seems a bit cynical as the companies are in no way connected by products or development .
  7. Full Panic mode Engaged. MOT emissions

    Alfa 159, Brera & 946 Spider
    2009 Ltd edition 159 with 1.9 engine, has been a bit smoky but new DPf and used additives/higher rpm etc... was concerned about new MoT smoke test but did it this morning and it passed on smoke but failed on emissions. Garage (local trusted indy) thinks replacing Cat is the best answer, DPF was...

    Recently failed MOT Alfa Romeo 159 JTDM Ti has had new oil air and oil filters. Every time touch the throttle and load engine black smoke is coming from the exhaust any advice ? Thinking of a carbon clean cheers
  11. MoT fail on emissions

    Alfa GTV & 916 Spider
    The 2003 ph3 spider has failed on emissions. Leaving it running, warming it up, thrashing the nads off it etc. has not made a difference. Garage reckon replacement cat required and as a ph3 it has twin one?. Firstly, does this sound ok and secondly where from how much? Current estimate is...
  12. emissions cheats and mpg

    General Alfa Discussion
    just reading that Mercedes Benz has now recalled over 700000 cars to have emissions software changed and the whole VAG emmisions cheating scandal I wonder how many more have been up to it and is this the reason why we in our 159's can't get any where near the mpg figures of our so called...
  13. New UK MOT - stricter diesel emissions

    General Motoring Discussion
    New MOT tests come into force - BBC News Seems the tougher emissions will only affect those fitted with a DPF, that's a relief. == Vehicles with a diesel particulate filter will now have to pass new tests. That filter captures and stores exhaust soot to reduce emissions. A diesel vehicle...
  14. 1.3JTDM 95 Failed MOT emissions

    Alfa MiTo
    Hi guy's, I'm really stuck and wondered if anyone could shed light on my next possible move. My car failed an MOT on emission of 1.9. I booked it in to have a DPF deep clean and forced regen with Halfords followed by an oil change. I then took it for a drive and brought it back for a retest...
  15. Excess emissions on a 916 Spider

    Alfa GTV & 916 Spider
    Having blown the crank (no 1 big end) on the original AR32301 engine. I have swapped the engine with one from a later 155. I have kept the sensors from the original including the Idle control unit and throttle body which I find is no longer available. The engine runs well except at start when it...
  16. VW now blaming emissions for breakdowns

    General Motoring Discussion
    It looks like VW are experiencing a spate of unreliability after they apply their emissions cheat-software correction fix... Apparently their EGRs (not used to having to do any work...) are failing all over the place in particular.. :D Reminds me of the old meme, based on the VW...

    My 146 is now clear on its Mot apart from the emissions, as follows: Fast idle: CO = 0.56% [should be =< 0.3%] = FAIL HC = 78ppm [should be =< 200ppm] = PASS lambda = 1.011 [should be between 0.97 and 1.03] = PASS Second Fast idle: CO = 0.44% [should be =< 0.3%] = FAIL HC = 98ppm [should be =<...
  20. 156 2.0 T.Spark emissions again.

    Introduce Yourself
    Hi Alfa lovers, I have recently purchased my first Alfa. Had a Fiat Stilo for the last 10 years. So its a 156 Selespeed with a 2.0 T.Spark. I don't understand why the DVLA have rated it with 240 G/Kg emissions when other motoring websites list it as 205/212. Otherwise I love this car.
