rubbish. I don't think any company makes a water tight snorkel for the D3, they are only raised air intakes. Exactly what i required for Morocco, allows cleaner air from higher up to be sucked in, rather than the dusty air lower down, how on earth is that a waste of time???
When it comes to water, i hit a deep puddle at the weekend laning, water washed over the bonnet and the wing level air intake, i'm happy that the snorkel will assist with situations like this, but, if i ended up in deeper water i would kill the engine straight away, if i was in my series at £400 for a new 200tdi engine i'd be fine, but, at £4000 + for a new TDV6 engine i'm not risking it!
