Thread: L405 cabin filter

It is obvious that LR didn't do much dusty road testing of the L405. Apart from the horrendous dust collection at the rear and that the rear side doors allow dust ingress, the engine bay gets covered in dust, the seal cross the back of the bonnet doesn't get near to sealing so the engine bay dust gets drawn into the cabin air intake at the base of the windscreen. The air intake into the bonnet is mostly from around the headlights with dust drawn from the engine bay resulting in quite a layer of dust inside the bonnet openings.
I'll be installing a layer of something on the plastic covers where the bonnet's rear seal sits to improve the seal the back edge of the bonnet, trying to get clean air into the cabin air intake and which might also reduce the drawing of dust into the engine bay a little.

I considered removing the raised screened air intakes from the tops of the mudguards and removing the mating seal from under the edges of the bonnet, but I'll start with just removing the mating seal blocks which might help a little.

Ya gotta wonder.. it must've spent hundreds of hours in the wind tunnel getting blasted by smoke.
2 or 3 in-car/underbonnet cameras wouldve shown all this...
