Hi everyone iv got a 09 Mk2 dispatch 1.6 dohc white/grayish smoke light at idle getting heavier with engine speed.
weirdly smoke stops every now and then for 10 sec or so then starts again.
Compression test showing 310psi at cylinder 124 with 3 having slightly lower 300psi
Leak off test all 4 injectors returned about the same (1 min idle and 1 min 2000rpm)
No fault codes or lights on dash and no coolant loss from resevoir????
Anybody got any ideas what to look at? egr and glow plugs were changed 2 months ago as it was showing fault codes but no engine management light at that time either.
