VW Bora engine

The message from snipped-for-privacy@chris-howard.fsnet.co.uk (Chris Howard) contains these words:

I think you'll find it has a coil per cylinder - and they're mounted on top of each sparkplug. The wires you can see are LT feeding the coil.

The covers are partly styling, partly noise control.

When you remove the cover and look where you'd expect to see tops of plugs/HT leads are infact individual coil packs. the thin wires you can see (3 per coil pack) are the feeds from the ECU.

There is no HT lead as such as the coil pack sits directly ontop of the plug (although on some cars there are "HT transmission boots")

To get at the plug you remove the coil pack from ontop of it by undo-ing the two torx headed bolts per 'pack and lifting it off.

Invariably you'll be pruchasing a torx bit and a coil pack now and then whilst you own the car, as they are virtually guarrenteed to fail at one point or other and you'll revert to 3 cylinders......!

Tim..

There are no HT leads, engine uses coil packs that sit on top of the spark. Unplug the packs, undo the bolts and pull the packs off and you'll see the sparks.

I wouldn't f*ck with them too much, they have a history of breaking easily even if you leave them be.

Same basic engine as TT btw...

The top of the 1.8T isn't a pretty thing, hence the cover. Protects the coil packs to some degree too from water / dirt etc..
