my name is Alexander and I am new to this forum and I would appreciate your help. My car failed the emissions test one week ago, and I was told that the fuel was too old (March 2020) and that the car needs some fast kilometres on the Autobahn. So at first I burned the old fuel till minimum, then put E10 and a gasoline cleaner in the car and went on the Autobahn again.
Today the CO was too high at idle (0,97), maximum is 0,30 in germany. At 3000 rpm it was okay. He tested left and right exhaust, also he closed the exhaust with old cloth.
The guy said go to Jaguar and check for codes. I talked to a Jaguar dealer/mechanic and he said that the car is too old and that he can’t help me.
Then I called Bosch and they said that they might can help me/read codes.
I have an ELM Blutooth Scanner but I am not sure if this is helping much. When I bought the car it had CO of 0,00. Now, about 2500 kilometres later its all messed up?
There was water under the tank lid but not above the gas-cap. The water drainage was clogged.
I have no check-engine light and the car states 10-12 liter/100 km which is quite okay. It runs smooth, has good power.
Thanks for reading and any help is appreciated.
