W203 air-con issue

[mercnewbie]

I have a Mercedes W203 2002 which last year had a leaking injector seal for some time and whenever I used the AC/blower it would pump an awful burning fuel smell into the car. After having the injector re-seated, the crap cleaned off the engine and the pollen filter replaced the smell went away.

The same issue occurred earlier this year with another injector so the same action was taken, but this time the smell has not gone. I have also tried a spray type AC cleaner which evidently masked the problem for only a short time.

I suspect the AC system is saturated in diesel fumes? In any case, the car will be for sale very soon and I was wondering if there is something else I should look for/could do to permanently get rid of the smell?

It may sound simple but have you thought of changing the air filter, which is situated in a casing above the battery ? If already changed try spraying a little febreeze or something similar onto the vanes of the filter

Yes, the pollen/cabin filter, I did say so in my initial post

In any case, the smell has gone - I guess it just need more time to clear.
