I am so glad I found this thread. I have a 1990 C4 that I just put a lwf (RS complete kit) and it smells like dead fish or a dead animal when I drive the car normally. I have to keep rpms under 1500 to keep smell from happening. It seams to be getting a little better, but have to take great care to prevent smell. It comes in from heating vents. I wonder how it can? Does it come in through heat exchangers and then up into cabin?
I hope that it is more of function of newer clutch. Really love to flywheel and clutch though.

It sounds like you're in decent company here... Yes, it still is a mystery to me how the smell gets from the clutch assembly to the interior cabin so rapidly... At least we can take comfort in that we'd likely smell any other untoward smells right away... an olfactory safety system...

Same here after just getting the car. A combination of not being used to the bite point and apprehensive about the car taking off at warp speed meant I was slipping the clutch. It was purely down to me and nothing to do with the clutch being on its way out.

Has anyone noticed that this is happens only when it is fairly cold outside?

If you slip the clutch and it makes an odor, that smell will be picked up by the engine fan and then pushed into the passenger cabin by the heater.

My clutch has about 4000 miles on it. Before winter it was nearly impossible to slip without REALLY trying and it didn't smell at all. Now it smells almost every time I pull away from a light... Any similiar experiences?

I think its related to heater usage in the cabin. If you're drawing hot air it will involve some of the air affected by the clutch.

As to a rodent smell, (noted above) rodents do get past the fan and build nests, if the car sits even for a few hours. I've had it happen in a Honda where mice built a nest in one night. ew.

My C4 has around 20k on the clutch. I only smell it when I let it slip too much under full power, or when I am trying to get the car up on some ramps.

Gotta a great fix for that: Cats.

That has permanently fixed a serious pre-existing rodent problem.

Cats are better company than rodents, too.

I've noticed it when it is cold, and running the heater. The smell in my car, with RS clutch and flywheel, is like I had asparagus for lunch a couple of hours ago, and just had to pee. I'd never smelled it before without the heater on, and it just happens at standing starts when the car is still cold.

I have the same experience lately; I could never smell the clutch but since it has become colder I can when pulling (gently) from a standing start. It's most noticable when the engine is cold as I have to give some more throttle to prevent stalling. BTW: I also have the LWF and a new clutch since April this year (12000 km since then).
