I am having a problem with my egr valve, brings on the glow plug light onto the dash and then loses power, garage have quoted me £700 to fix however it doesn’t often come on so I have been putting it off. Anyone else had this problem and is there any other solution? Cheers 

I did see a post about this however I did try this and nothing seemed to happen, I’ll change the cable and see if it works,

cheers 

I have a 2010 Audi A3, it has the symphony head unit. I have a aux Input near my handbrake however I can’t seem to change the radio onto aux as there is no source button, can anybody help?
