melonhead Posted February 6, 2010 Share Posted February 6, 2010 Hi, my Galaxy failed it MOT today on exhaust emission. Could anyone help me with this problem please. It's a N reg 99,000 miles on clock 2 litre The results where as follows Engine oil Temp; Temp gauge checked fast idle test; limits Actual value co; 0.3% 1.56% FAIL HC; 200 ppm 138ppm PASS upside down y; 0.97-1.03 0.965 FAIL 2nd fast idle test; co; 0.3% 1.43% FAIL HC; 200 ppm 72 ppm PASS upside down y; 0.97-1.03 0.964 FAIL natural idle test; co; 0.5% 2.25% FAIL this didn't come out on the post how i laid it out. the first numbers are the limits and the red numbers my results. Think i've listed everything, it did over heat a few time about august time. I replaced the themastate, the temp gauge doesn't go any higher than the N on the gauge around the city and on the main roads just above the white square. Don't no if this is normal or even relevant to my question. Many thanks in advance to anyone who try and help me Quote Link to comment Share on other sites More sharing options...

Many thanks in advance to anyone who try and help me sounds like you have a few issues the temps a bit high the co2 is high so it could be a lot of things really the engines almost at 100k so could be valve seats it could be worn pistons the cat the lambda sensort or a mixture taking it to a garage is best they can test all the parts that need tested Quote Link to comment Share on other sites More sharing options...
