1.9 TDI AWX High Emmisions
Hi, I need your help.
Good friend of mine and customer has 2003 Skoda Super 1.9 TDI PD AWX. For the last 10 years I'm the only mechanic who look after this car. So far was so good 3 days ago I did full service on this car because car was going for MOT test incl. fuel filter, I replaced also thermostat because car heated up only up to 60C, and changed also coolant temperature sensor G62(came up during diagnostic), and before I replaced it car for long time kept high revs on idle about 1200-1300rpm. After the service i cleaned njectors with Liqui Moly Injector Cleaner and gave it good blast on motorway. After all that work done car looks and drove perfect, didn't find anything wrong with it. Today customer back to me after MOT test with bad news that car didn't pass it because fail emission test. On the MOT report says: Smoke 4.220/m where the limit for this car is: 3.00/m. Last year this car has smoke 1.700/m, so what happened??? Diagnostic does't show any faullts, injectors looks fine, so where is the problem??? |

Hi,
fuel mixture is too rich too little air or too much fuel - air filter bad - turbo control - injector demaged - MAF demaged |
