Hi Everyone
My Audi A5 1.8 TFSI 2013 will not start.
The starter is cranking the engine as normal and sometimes the engine will ignite for a second and then die again, but usually there is no ignition.
I have changed the crankshaft sensor and also tried one time with another camshaft sensor. This gives the same result as before.
I have tried with some starting fluid in the air intake, but there is no reaction to it.
I have checked the high and low pressure fuel pump with obd and both seems to be fine.
There is noe fault codes in obd.

Any hint for what to try next?
