Hi,

I noticed recently that the wires to all my coil packs are cracked. It looks as though the insulation has just perished from heat from the engine. Photos to follow shortly.

Has anybody else noticed anything similar, or does anybody know how much it would cost (and how easy it would be) to replace the wiring loom in question?

Thanks in advance.

Photos.

Design fault and therefore should be sorted out by skoda uk?

The last picture shows cracking on the brown wires in the top left of the picture as well......

Really? This is music to my ears. Only thing is, I got the car second hand (private sale). It's a 2001 model and has done 72,000 miles.

Well that is the way I would look at it. *I* would not expect the wiring to crack due to heat. If it has cracked due to heat from the engine, then to me that suggests a design fault - either in the routing of the cables, or the materials used to make the cables from.

However my experience of skoda customer service has never resolved things. They took great pleasure in explaining that corrosion occurs on bare metal (not something I would expect to find in the windscreen wiper mechanisms....)

Hmm, okay, I'll see what they say but won't hold my breath.

I don't suppose anybody knows the cost of the wiring loom, and whether it's a short section or interconnected all over the place?

A complete harness for the engine bay was priced at £273 a few years ago. I don't have the current price.

:eek: That rules out that option, then!

This might help.

I noticed mine is doing the same but tbh im not really worried about it

This might help.

Thanks, I might try that in the summer.

Bathroom silicone sealant works a treat. May end up a bit messy if you're not painstaking, but electrically it's the mutt's nuts - I've used it on high-voltage wiring in industrial applications.

High temperature heat shrink will do it if you can get the wire out and back into the connector/

I'd agree that that is a manufacturing or design fault though.

That's a good idea.

EDIT: What about splicing out the cracked section of cable and soldering in a new middle section? That way I could slide the heat-shrink on at the same time. Soldering in cars (with sensitive ECUs) worries me a bit, though.

How does that sit with the warranty? I thought if it was older than three years, you were on your own, or is there some kind of good will policy if you can swing it?

Skoda wont to anything about it as there is no recall about it.

Plus it would be hard for you to PROVE its a design fault rather than claiming its a design fault

I've got the same.

Not caused any problems tho'.

Audi do a 'foil bag' type thing (On VW Vortex somewhere) for about £40.
