SOURCE: gas smell

I would check to see if you have any leaks also. But what is more important is, is this happening when the vents are on recycle air or just when you have them on fresh air. If its when the vents are on recyle air. You not only have a leak, but the gas is getting in the cab of the car as well. This is a very serious problem.

start by going to a news paper company, and get a big roal of printing paper. They give this away when the roal is almost used up. It is white and durable. Put the paper under your car and secure it with rocks or something. Run the car until the problem starts to happen. Now let it idle for a few minutes, and start looking on the paper to see if you get any gas drops. Make sure the hood of the car is closed, so it doesn't evaporate before it falls to the ground. If after a few times you still cant find the problem. Meticulously go over every inch of your fule lines. especialy around the filter. The plastic clips are very easy to break with some age. Hey guess what this could be a great time to REPLACE your fuel filter. follow the lines especialy around the top of the engine where there are a lot of rubber lines and plastic connections, that can be disolved after years of use, or days of using fuel with fingernail cleaner. DONT USE FINGERNAIL CLEANER IN YOUR CAR. THIS IS A URBAN LEGEND, AND HAS KILLED MANY CARS.. let me know what you find and how this goes.

SOURCE: Heater Core Leaking

you could quick fix! but you will have no heat, 1st under the hood, look at the back of motor, follow all you're radiator hoses, take two hoses off the heater core stick a pipe that is big enough then clamp the pipe down. to both sides of hoses to the pipe you will eventually have to replace heater core!!

SOURCE: strong antifreeze smell when running the heater in

Usually a smell of antifreeze in the cab when the heater is running is a sign the heater core is leaking. Just becasue you dont see a leak at this time doesn't mean there isn't one. It might small enough that the haet from the core is burning off the leaking antifreeze. I would suggest replacing the core before you get in one day and there is a puddle on your floorboard. Or if you go to a local parts store and rent a cooling system pressure tester, wait until the vehicle is cold, pressure the system to 12 lbs and then check for leaks. Hope this helps you out......

Testimonial: "that is what i also thought, no puddle yet, just waiting. I tried a sealant for now, but will get a heater core"

What kind of smell? Sweet like coolant or a musty, decomposing like smell? If sweet like antifreeze it could be your heater core if musty/mildewy or decomposing like smell try replacing your cabin air filter.

My 2009 xf has just 34000 miles. Last week I start the engine and I could smell gas in the car for about 5 minutes. I waited until the smell was over to drive. From that day, every other day I was sme

Was this the smell of burnt fuel or raw gasoline? If this started after it began getting cold outside this can indicate a problem with the EVAP system in the car. This may or may not cause a check engine light.

This site reported a 2010 model of your car having this same symptom.
They found the injector seals to be leaking.

Mar 2010 4340 0 injector seal leak causing "gas" smell in cabin - replaced injector and new seal kits on other injectors

That can be a very serious issue with the potential to cause a fire. I would have it checked by a professional mechanic and specify your concern on the injector seals being checked.

Jaguar 2.7 diseal -s type. when i put my heater


Very common on this car is the EGR valve, it is basically an Exhaust Gas Recycler it reuses the unburnt fumes from the exhaust and pushes them back through the engine to burn again. If this part has failed or has become dirty which is quite often the case on Diesel cars then it would certainly cause the smell in the cab and the ticking.

It's worth mentioning that these can be very expensive around £250 at worst but in most cases you can remove them your self and clean them with carburetter cleaner, don't use anything else though.

Inside the EGR valve is a small sensor not dis similar to that of an air sensor, just spray it with the cleaner leave it to dry naturally and then refit it. if it has worked you will notice the car will feel more responsive to. and the ticking would stop.

Hope this helps

Have an '02 Saab 9-3 turbo, 140,000 miles drives great, but have strong exhaust smell coming into the cab through the heater vents... Can't actually see exhaust leaking, but when I pop the hood I can smell...

Have the catalytic convertor checked, sounds like it may be trying to stop up. Some cars have an exhaust vent between the exhaust manifold and the exhaust pipe, it could not be operating properly. The purpose of this piece is to help the engine warm up in the winter to get the heater working faster. Most of them are vacuum contolled and the vacumm line might have a small hole or the cast iron unit is old and just stuck. you might free it up if you can get it off to work with and lube and replace on the car.
