If you want to do river crossings, this is what you need first an foremost. The breather holes are at 30 cm and you don’t want to suck dirty water into your drive train.
I would disagree on this. Talked to the mechanics prior to our trip and they told me the air vents would not "suck water" just like that. That they are made to get some water from time to time and that it would in no way mean the oil is washed out. Adding oil on regular maintenance would be fine.
He said the Seikel kid is only recommended if you'd do this constantly (a Cali living in the highlands).

It's been 2 years since we've been to Iceland with out Cali T5 4motion, we've done > 30 river crossings, deepest one was probably 60cm. No issues at all!

We have the air suspension, the Rival plates (full packages 6mm, installed it myself without a pit (though that would be easier), very straightforward), and the raised air intake (the one you can easily install yourself and reverse after that, from a German guy, Relleum kit, I'd recommend it).
Gearbox removal etc.. not necessary.

Well, we disagree here. If you drive through relatively quickly you’re OK. If for some reason you are stuck in water for some minutes the cooling drive train will suck in a lot of dirty water. The oil won’t be washed out, a bit of water is also not the real problem, but the dirt/sand that comes with it will damage your drive train in the long run.

I think we're more or less in sync; it's just a decision if it's worth the investment price and time to have it done (about 600 euro if you cannot do it yourself, and I for one didn't dare to try this), vs the number of times your car will be visiting Iceland.
Even though I plan to go back at least twice more with my car, I chose not to do this.
If you get stuck in a crossing, you probably did something wrong or took too much risk.
Risk can be reduced by wading through the riskier ones with a fishermans suit on foot first, to check if there are big stones and how deep it is.
I found the water in Iceland to be crystal clear by the way, at least in the time we visited, never saw any muddy currents - so not afraid of dirt getting in.

Well, where we are not risk takers, we have had a situation where we went in and when we were halfway someone from the other side dived in :oops: while we couldn’t pass each other in the middle (the driveable bed was just too small).
Before that was sorted, we stood longer in the water then anticipated...
And it may depend on the route you take. Don’t remember exactly where but we have been in the water for quite a long time, following a riverbed that was the road! And there is route F622 where you may have to drive through salt water - also something you don’t want in your drive train.

The rain rivers we crossed were relatively clear yes, although that doesn’t mean there is no dirt in the water. But the melt rivers were quite murky.

But in the end you are right: you have to assess the risk you are willing to take i.e. the potential cost of damage vs the investment needed to avoid it. We didn’t dare to take it, you did!

Thanks for all the info guys, really useful.
A couple queries,
bvddobb I'm a bit baffled about you saying that the air intake is only about 40cm. Ours is behind the top of the front grille and is at about 90cm. Yes the ducting is lower but my plan is to seal the joins in the duct with waterproof tape. Looking at the Relleum kit I can see that it is a lot higher but what stops rain/washing water entering the intake from the slot in front of the windscreen and gathering in the bottom of the corrugated tube where it enters the air box?

Breather kit. I think we will go for this. Can you tell me how long it takes Siekel to fit them. We are in France again soon and can divert to Siekel to get them done. Days job or more?

Hi Briwy,

I was talking about the duct. That opening is at approx 40 cm. It will suck in water from there.

The Relleum kit duct is above the lowest point below the windscreen vents, where rain water is drained, and with a bend. W have never had water ingress there.

If you can read german, here is an interesting article where, among others, Peter Seikel comments on what makes sense and what is nonsense preparing a VW van for Iceland: under this link.

We had the Seikel breather kit and their underside protection fitted as a day's job while visiting there. While visiting, they gave us an interesting loaner for the day, to try :cool::

The air intake has a leak water separator just before the filter, so it's made to get some water. If you drive through heavy rain or deep splashes on the road it also gets some water.
So I think taping joints is not very useful.
The Relleum kit is still a couple of cm above the place where the front screen/washing water are collected and drained. Nice piece of kit, easy to fit and undo; gives a lot of certainty.

Ok thanks very much. I'll get the Relleum kit on order. Yes I did wonder if the duct had a water trap in at the bottom but couldn't see it easily.

Just discovered Seikel have an agent here in the UK so I'll give them a ring and see what they can do.
