Thank you for your reply. The problem is that the smell is there when the car starts to heat up with the A/C off. I have used the 'fogged' a/c cleaner, but that did not make any difference. I am pretty sure it is coolant I smell. I get the same smell when coolant drips on the hot exhaust. I do not have any coolant scum on my windshield though.

Does anyone actually reads the posts, or just the topic title?

The only official "special" LS400 models for the U.S. market I'm aware of were the 1994 "5th Anniversary Edition", the 1997 "COACH® Edition", and the 2000 "Platinum Series". There were sometimes special LS400 models sold in other markets such as the 2000 LS400 "Millennium Edition" for Canada which was essentially the same as the U.S. Platinum Series except without the emblems on the front fenders and the American Express credit card tie-in. There are, of course. those cheesy, vinyl top "Palm Beach Edition" Lexus cars from a Lexus dealer in Florida -- I thought I had a photo of one of his LS400 aberrations but these other two will have to do. Holy crap, that looks !!

any updates about this?

the guy in the below link has exactly the same issue http://www.lextreme.com/forums/showthread.php?t=9020 Anyone here knows what a vapor trap is?

Welcome I'm also from the Netherlands, but have given up living there many, many moons ago

Indeed I do :) I have found out that these are quite the collector's item these days. Lexus LS400 RC Limited Edition :)

Thanks Steve, I'll give it a try

umm..I have never even heard of them..lol How can they clean a closed system from behind the passenger seat?

It could be Wald International. Here's a Wald UCF10

No, it's not methane. The smell is really only there in the morning, when she is warmed up. The rest of the day is fine. Iknow the smell of a bad cat., that's more like a rotten egg smell :)

I have recently removed tint from windows. It's a ***** to get the glue off. I found using a stanley knive blade and autoglym tar remover worked the best. It's still a nightmare though. I'm not sure if the Autoglym range is available in the US?

ah, pollen filter was changed earlier this year.

lol..the smell is not coming from outside. Ah but the A/C filter could be clogged causing the poor air flow and the smell I don't have poor air flow though. Just to be safe, where is this A/C filer located? Is it the pollen filter?
