Driving around again today enjoying the sun and engine conks out! This is the second time this happened and so checked the fuses and the ignition coil fuse had blown, again. Swapped and got off on my way just to get me home. It's pretty obvious it is the coil but when looking under the bonnet I can't see it!

Not had the car long so any advice as to where it is would be appreciated! Is it in with the battery behind the front wheel or elsewhere not immediately obvious? Do i need to remove the bonnet to get access to it?!

Thanks guys & girls.

Rich.

The coil pack is only visible if you take the air box off. Its situated on the opposite side of the engine block to the exhaust manifolds, towards the passenger compartment bulkhead. www.clever-trevor.com sell them for £72 (IGNITION COIL PACK, PART NO E6523). I imagine its a VW part

Perfect, thanks.... just whipped off the airbox. Doesn't look to be any corroded wires or anything so I can only assume the coil is shot. Bit of a mission to get to though! Good job I've got the weekend to tinker with it!

The coil pack is supposed to be pretty robust. Racing Green told me that if its gone wrong it'll probably look like its bloated, if you know what I mean.

I suggest that you should check the spark plugs for a spark first. Just remove the 'speed6' cover plate (2 allen head socket caps) and take each HT lead off in turn whilst the engine is running. You should be able to hear a change in engine note.

Alternatively, apply a thermocouple to the exhaust manifold. Cold manifold = no spark.

You might find that it is the fuel injectors that are causing your problem, or rather a broken loom is. This is what happened to me. I ended up linking the wiring between cylinder 1 to 2 and later 5 to 6.

Thanks for the help folks. Got hold of a coil yesterday so just got to but all the bits back in the box, so to speak, and should hopefully good to go. I'll let you know the results. Fingers crossed.

Incidentally the old coil looked in reasonable nick, bit rusty on the back but no obvious signs of wear so I'll have to see if I've managed to narrow it down. HT leads looked fine, but then the car has only done 7000 miles so not really expecting the coil to go, but have to see!

Just had a brain fart, guys.....

silly boy me decided to whip off the old coil without making a proper note of the order that the HT leads go into it... I mean they're written on the old coil and new one from top left as you look at it:
1-3-5
4-6-2
but I could have sworn that the bottom line was 6-4-2...! Anyone got their airbox off at moment that could help?! Thanks all.

- the mong!

my coil pack also looked in good nick other than a small crack in the plastic, must be goosed internally, all good now though, glad you've got it sorted also.
