I was driving my 1999 Audi A4 1.8T Quattro and then my check englne light statted flashing so I went and got the codes scanned. Here is the result:

P0422
P1237
P1238
P1239
P1240
P0304

I know that the spark plugs needed to be changed soon so I am going to do that tomorrow and will reply on this thread and let you all know if that helps at all.

Thanks,
Jonah
