Hi All

I've got error code p0170 once again, I had this at the start of the year, replaced the MAF and all has been ok since. Yesterday EML came on again and the reader has spat out the above code.

Having read this forum some suggest cleaning or replacing the EGR as well as checking for air leaks, so quick question what is the exact torx or tools required to remove the EGR on a 1.8 2003 Vectra LS as I don't have many tools so will have to get the exact one.

Thanks in advance as always!
