ill try and cut my story as short as possible but hoping someone has had the same kind of problem and had theres sorted.
1999 mk4 1.6 8v club
right, i had a problem about 4 months back with a code showing 1405 which is EGR valve then blanked it off and worked fine ever since.
about 6 weeks ago i had a horrible problem with the car misfiring running on 2 cyclinders. i done the paperclip test again and came back with the code 1405 again but i also done a diagnostic test and it came back with 0352 which was coilpack. i changed the coilpack and it wasnt working but one day i risked it on 2 cylinders and it just kicked in and worked till now.
I then did another paperclip test and it came up with 0352 again so changed the coilpack again. but has never worked since. so its still running on 2 cylinders. i then checked the plug that goes into the back of the coilpack with a led test and one out the 4 wouldnt light up so i kept fiddling with wires as it might of been a loose connection then it started flashing and came on and off so i kept fiddling and it stayed on.
the car started and ran on all 4 cylinders so i thought i had it fixed anyway came to go out init and it ran back on 2 cyclinders as soon as i started it. so had a fiddle but no luck.
today i had a fiddle and it keeps comin back to life but dies out again after about 10 seconds. i done a paperclip test again and it now came back with 1405 again which was egr valve again! its getting on my tits now lol i hope someone can help.
theres a light brown and black bit thats above but behind the battery infront of the fuse box thing that i fiddle with and it seems to flicker the light.
