Bit of a heads up here ..
I did my first major with plugs on one of these a month ago .. the bolts that held in the coil packs were heavily corroded .... i cleaned them off and applied a generous amount of ally grease to the bolts .
The single bolt that retains the coil pack basically goes through a metal tube of approx 1 inch ( 2.5 cms ) .. it's here it corrodes .
Had another one in today so my second one .. 5 bolts were ok .. but no.2 coil was corroded to the point it snapped the retaining bolt off.
Coil is now corroded to the head on what's left of this bolt .. plenty of levering , penetrating oil .. heat .. you name it and i got the coil off .. the bolt however is seized in place .
Not sure its going to come out to be honest as i have this to face tomorrow .
I have some pictures which ill upload later as i left the camera at work .
In short .. it's worth getting the coils removed and the bolt greased on each one imho.
Considering this is at 4 years old .. considering out of 2 cars i have had problems with each one then i'm a little concerned atm shall we say .
This is obviously just what i've seen but as always .. i say What i have seen .
