Thanks for all the replies i have had on this... So i ran a diagnostic check on the A4 and it came up with Code P0420 which lead me to here http://www.p0420.com..Thoughts please?

Thanks again I'll post up if i get this fixed!

Hi Bradley, Thank you for answering me so quickly, The smoke is white white and the car smokes when the engine is warm?

Hi Audi A4 1.8T 2003 – Can any help diagnose white smoke from exhaust? I have had engine flushed and 54 point service carried out with all levels topped up, garage saying may be catalytic converter so used cleaner twice and no difference. Any ideas?

New to Audi and popping in here to say hello! Just bought an A4 1.8t that needs a bit of tlc..hopefully with the help and knowledge of this forum it will be up and running smoothly again!
