hiya all has anyone got an idea why my car smells off rotten eggs when running its a 2.7 diesel 2009 modal have cleaned and replaced washer fluid as thougt that could have caused it but not IDEAS PLEASE .THANKS Cliff

 

Where are you smelling it? Can you find any place where it's stronger?

 

Could be a bad cell in the battery.

 

Rotten egg smell = sulphur dioxide.
Commonly happens when a catalytic converter stops working properly.

 

Apparently you can get a smell like that when the AC drain tubes get blocked and water backs up. Think you can clean them yourself although I don't know details of how best to access it

 

cheers that make sense. as checked all the other faults .thanks again cliff

 

thanks for getting back i have been told possible ac drain blocked which sounds a good call as have checked most other things ..cheers cliff

 

In the spirit of starting where it's easiest, have you replaced your cabin air filter? They sometimes will get wet and moldy and can make that smell. Honestly, I haven't replaced mine since owning this car, so I'm not sure where it is, but I know this is a common issue to all cars.

 

To be clear before you start changing batteries or cabin filters,..Where do you smell this odor?..Inside the car or outside by the exhaust? and when an how do you smell it?..i.e., environmental control settings, car running, at start up, or after a run to the local *** shop and back, etc.

 

thanks for getting back ill check see if they have been done cheers cliff

 

thanks for getting back. To be honest with you i still think it could be stagnent water as it seems to happen after using screen washers when i get a chance ill clean out the screen washer bottle again .cheers cliff

 

hiya again i have cleaned washer bottle again but smell starts to come in car as soon as i start engine and auto vents open could it be filters and if so do you know the location of them ..cheers Cliff
