Diesel S-Type cabin fumes

[Geoffpuma]

I've noticed recently that, when starting up from cold, there is a noticeable (but not particularly strong) smell of fumes in the cabin of my 2006 S-Type Diesel sport coming through the heater vents.

Has anyone any experience of this problem and a possible cause/cure?....

Many thanks.

Hi Geoff.

Your problem intrigued me, so I did some research on it. It looks like quite a common problem. As I understand it, the exhaust is by the nearside front wheel, which is near the air intakes used by the climate control. So as you fire the engine up, the climate control sucks some of that exhaust gas up though the air vents into the cabin.

There doesn't seem to be a fix for it, other than maybe not having your aircon on when you start the car. It doesn't seem to be an indicator that something in your car has gone wrong, which is obviously good news. I hope this helps.

Yes, it is a problem for me too and not only when starting the engine. I cannot use all three demisting switches at once because the same thing happens...it isn’t mild, it’s toxic! Maybe there is some sort of cover which could prevent the fumes from entering the cabin? It didn’t used to happen when my car (07) was newer.

Hi Laura and welcome to the club.

I get the same from my s type  -- these cars have an auxiliary heater which heats the car interior on a cold day.  But the diesel whiff on my car only lasts about ten seconds.

I think it is possible that some of the covering into the cabin has worn or is a bit loose.

Let us know how you get on.

Regards,

Peter.

I had same thing and it came from exhaust manifold had it fixed no smell now

Hi Alasdair,

How much was the fix, and did you use an independent garage?

I've got the same problem.

Was it the auxiliary heaters exhaust manifold?

Cheers.

hi

the exhaust pipe is usually a corrugated metal pipe that splits and lets the smoke in the engine bay, rather than away from the car

the corrugated pipe can be bought on eBay and replaced, which should cure it

cheers

Hi Geoff

I have the same type of Jag as you & had the same problem, I took it to my garage & it was caused by one of the catalytic convertor that had a hole in it, that was replaced which cured the problem. Jaguar wanted the best part of a £1000 for a new replacement but my garage got an aftermarket one for £450 Fitted.

Best of luck

Welcome to the Club, Lawrence.

Luckily I have rarely had the smell of fumes inside my s type.  I wonder if Geoff still gets the fumes.

Having a good mechanic can save a lot of money.

Hello everyone.

I am about to 'inherit' an S Type diesel and believe it has the same issue of fumes in the cabin.

I joined this forum to get more information on the subject and my extensive research suggests that this is quite a common issue and is caused by a leak after the manifold and in the catalyst area.

It appears that there are two different types of exhaust pipe repair, one with a bend and one with a straight piece of pipe and they’re LHS and RHS.  If you have this problem, it appears that it can be solved by buying a repair kit, cutting off the leaking piece of pipe before the catalyst and fitting the specially modified part.

Here is a picture of the kit and a link to one of many suppliers of this repair kit …

If the catalyst itself is cracked/leaking, that’s a different repair!

Welcome to the club, Cameron.

I have an S Type Diesel [07 plate] which I have had for just under 9 years.

I have had a mild puff of fumes on the odd cold days, but as a retired  person I can choose the time I start the engine.

Luckily, I was given some very good advice when I first got my car, and mostly about fuel and what best to use.  I was advised to use Premium fuel preferably Shell and to ensure that the exhaust system should be kept clean.  [I live 500 yards from a Shell Service station].

My exhaust is a stainless steel one and I make sure that I have a good additive to make sure the exhaust from engine to the fresh  air.  I sometimes get the yellow light which I cure.  Three months ago the AA diagnosed the problem as EGR valves but my mechanic felt that the exhaust system should be cleaned which he got an expert to spend a day cleaning the whole exhaust system which made the engine like new.

I am not an expert for engines with my tool kit consisting of a lump hammer and a spanner, so I do feel that your knowledge will be very useful to many of our members, some of whom are very knowledgeable.

Enjoy you car,

Regards,

Peter.

Good day to you all and thank you Peter.

A quick update on the exhaust gasses entering the cabin issue.

This is a ‘well known’ problem … well, it is if you know about it!

I researched it thoroughly and found that it’s common for a small crack to appear just after the three-bolt flange and decoupler assembly and before the catalyst.  Mine was just after the crushed wire part in the attached pictures.

I believe Jaguar were the first to make the repair kit to avoid customers having to replace the catalytic converters in their entirety which is very expensive!

The kit is now widely available from various suppliers but make sure you get the kit that has the crushed wire part because, as I understand it, it helps stop the transmission of noise and vibration down the pipes.

I bought a quality repair kit from Berkshire Jag Components, and they were great to deal with.

It’s a complete kit which includes everything you need, and it’s being fitted now.  Link below.

Jaguar S Type Catalytic Converter Diesel Repair Kit R.H - Berkshire Jag Components

I hope this is clear and helps someone out there. 🙂

Now a question.

Jaguar S-Type 200 Diesel Saloon 2.7 D V6 2720cc AJD. VIN SAJAC031177 N74478

I live in central France and my local garage is doing the ‘cracked/leaking exhaust repair/conversion and they’ve told me I need to replace the part in the pictures.

The description I got was … ‘An exhaust collar/ catalyst flange’ but have been unable to find it on of the parts catalogues I know of.

Can anyone identify this part with a part number please?

I’m going to do a separate forum post for this too.

Thank you in advance.
