Cali now sold
Some time ago I started our van up and the engine management light came on. This turned out to be caused by an animal (fox or squirrel) chewing the wiring underneath the van.

More recently, another forum member (Mags21) has had a similar experience, except this time the problem recurred a week later.

I thought I'd have a look under the van and see if anything could be done to deter animals causing this expensive and inconvenient damage. This was my solution; if you decide to do the same you will need about half a metre of rubber gas pipe and a quantity of stout cable ties.

The wiring in question can be accessed by sliding underneath the van just aft of the nearside front wheel. To make access easier you can run the nearside front wheel up a ramp, taking adequate safety precautions while you are under the van. There are 4 wires as shown below.

Take the rubber gas pipe and slit it from one end to the other so it can be slipped over the wiring.

Next, cut it in to appropriate lengths to cover each of the wires and press it over, being careful not to disturb the plugs at the ends.

Finally, attach as many cables ties as you like over the pipe covered cables. Do not trim the ends of the ties right back, but cut then at an angle as shown below, so the ends are sharp. You can also attach ties to other vulnerable areas on the underside, rubber hoses, suction pipes etc. These sharply cut ties effectively mimic barbed wire and will make extremely unpleasant chewing for anything that fancies a bit of Cali wiring for dinner :D

Hope this is clear, it was a bit difficult taking photos under the van ....
 
Thanks alot for posting this. That looks really good - I wonder if I can persuade the mechanics at the workshop to do this in addition to the repair work.Is it easy to obtain the rubber gas pipe? Thanks for thinking about it and posting the pics.

Gas pipe can be obtained from any caravan/camping shop. I just happened to have some in the garage, it's probably out of date as it's stamped 2004 ... good enough for this purpose.

Actually, you could probably just put loads of "sharpened" cable ties on the original wires, this would deter most chewers; although the rubber gives something for them to grip on and stop them rotating.
 
Thanks again for the advice - looks like this could be a good solution. The sharp ties definitely look like they would deter any more chewing.Your help is appreciated.
 
After a third attack on the wires (only one small nibble this time) my local independant workshop managed to cut and re connect the damaged wire and then covered all with black tubing and cables ties and then smeared all with grease. VW were not prepared to do this but the local boys were happy to oblige with no charge for doing it! I have used them for many years for other vehicles.Pictures are before the grease was applied.Thanks to motacyclist for info shown above.

After having these wires chewed off twice resulting in the oil level sensor warning and the coil light (exhaust temp sensor). We have now done the same. Using some garden irrigation pipe.

Also smeared grease over it.

Hope this holds out.

Pics for attached in case it helps anyone else.

How rural do you guys live if its happening there?
or likewise camp?
I saw a TV programme and they blamed pine martins.

As rural as South London... It’s happened twice outside my house.

It’s been all over Europe and the UK without an issue.

Quite common in Germany, the marder. They love chewing
through cables and hoses.
I didn´t know that they´d made it to the UK though.
 
Glasgow for us .....three times on our driveway, urban foxes!
 
If my experience last week has anything to go by, rub the cables with scotch bonnet peppers. You will need gloves to apply it. That will keep the vermin off them.
 
I went to see my pal in Switzerland and he introduced me to this problem which I had not heard of before. He bought some cheap solar powered lights that switch on with infrared motion detection and this is enough to frighten the critters away.
 
So it's been my turn for the fox/rodent problem :mad::rage
We were just about to head to away to the Isle of Wight for a few days and a message came up saying "Error: AdBlue (DEF) No engine start in 650 mi." Sounded pretty serious and so we nipped in to VW Breeze in Portsmouth, thinking they might be able to clear a fault or something easy. They had a look under and found a chewed pair of wires:headbang!! So we couldn't sort it then and there and took our chances on the 650 mile countdown. VW Breeze were excellent and really helpful. A couple of weeks later and £470 lighter SMG have replaced the part and wrapped the cable in a kind of heavy duty tin foil. Having heard all the stories on here though I took a look and figured that it's still a bit exposed - as are some of the other cables. I'd like to do the gas pipe and cable ties trick that @motorcyclist did but in the first place I've wrapped over the top of the tin foil with some anti-rodent insulating tape I got hold of that's supposed to have a nasty taste and smell.

The other option that was suggested was to spray ACF50 over the cables but I'm guessing that's going to make a mess and attract dirt and grit?

It would certainly be a whole lot easier if there was a shield/guard you could get.

Here's some (not that great) pics of the chewed wires, the tin foil wrap and then the tape wrapped version, plus the tape

Why not just wrap the wiring in tin foil, quick, easy & keeps them fresh too!!
 
Hope this solves your problem - we have had no further incidents since the three in summer 2015.
 
Just resurrecting this old thread after coming across this

 
Warning light came on so i had a look and
my lambda sensor has been chewed through with
a Marder so i got some mesh and cable ties and hopefully
it won't like the new terrain.

Used to live where a lot of stone martens were around and kept creeping in the undeside of cars. This did the trick:

A Marder?

I have just been done a 2nd time by the blighters in 3 months. Another £500 to get fixed. Has anyone had much luck with covering the new wires/Sensors in glue mixed with Chilli powder, I am thinking some PVA or Wood Glue, or maybe vasaline mixed with a load of chopped scotch bonnet chillies smeared all over the wires.

The repair specialists who is going to fix it for me again its going to thread the wires through some aluminium piping. But I think I need the cable ties and Chilli glue in addition to be on the safe side.

Does anyone have any additional advice on how they have solved the fox problem?
