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.![smile2]( "smile2")
3 days ago I did full service on this car because car was going for MOT test including 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 1200-1300 rpm. After that I 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 not show any faults, injectors looks fine, so where is the problem?????
