Hi guys I'm new to the forums didn't even know they were here lol any way could do with some help please if anyone can help

I own a 2003/04 audi a4 cabriolet v6 2.4 started having problems a few weeks back with misfires and the whole dash lights flashing and the car was losing power then it would be fine for an hour or two then it would do it again
Replaced the spark plugs ignition leads and all 3 coil packs and its running a little better but still not perfect can anyone help please

 

Check the engine fault codes with an OBDII reader, clear them, and then see which codes come back (if any). This is how you can diagnose the problem (i.e. which cylinder is misfiring).
