Its the usual problem of it going into limp mode - vacuum pipes all fine. checked the vacuum valves and the filters fine. I may have connecthed the vacuum pipes the wrong way round and its happening more often now.

how do i know if i have done this?

also, have yet to clean the MAF. its a pain in the arse wen EM light comes on.

i know it aint a corsa, but CS iIMO has the most helpful ppl around, other forums r shite!

Glow plugs are only used on the DTi when it's below 3 degrees iirc.

hmm.... engine man light comes on first thing in the mornings if i touch touch accel

then when i touch it after its started, light goes off

this was the only fault that came up on diagnostic.

but its not running right. think i might clean the MAF.

but i have a mk5 golf gt tdi, and the swirl flap regular is seized or something!

everything car related is doing my head in at the moment!

it cant be plugs tho?

coz my performance is affected

turbo kicks in too late. like 2600rpm.

if i set off at early revs, takes forever to get moving!
