hard to explain this one, but at times my car seems to have a rather strong smell of diesel exhaust fumes. I've smelt this before on other diesel cars, mostly older cars, and at times there's almost no smell at all.
It's not unburnt diesel, so I don't suspect any leaks anywhere in the fuel supply area.

Since this is my first diesel I'm wondering if this is normal, or is it a sign of some impending doom that needs to be dealt with now before it gets more expensive? Got - 2017 SDV8 Autobiography in Loire Blue

Most likely be a diesel leak somewhere under the bonnet, should be easy to see

Do you mean on the exhaust side rather the feed side? Or something burning off on the hot engine? Got - 2017 SDV8 Autobiography in Loire Blue

More likely to be the feed side and the heat off the engine makes the smell more noticeable.

Would I expect to see any drips on the drive, as I don't have any? Got - 2017 SDV8 Autobiography in Loire Blue

It only takes a tiny amount to smell it, not enough to drip down to the ground.

OK, I'll take a look around tomorrow. Any specific areas I need to look? Got - 2017 SDV8 Autobiography in Loire Blue

Sorry I don't know the TDV8 engine, look for the fuel lines, fuel filter and pump. Follow along the fuel lines and check for leaks

If it is a leak it will probably be tiny so check carefully

You could always take up the driveway into Mick's estate and have him look it over

Couldmbe to do with the FBH, noticed that it smells quite fumes on mine of recent. More exhaust than supply tho. There is nothing that can't be fixed with a hammer😜😜

It's been like this on and off for a few months, so the FBH hasn't been used until the past few weeks.

I was forgetting about it, but my son noticed it the other day which made me think it's time to investigate. Got - 2017 SDV8 Autobiography in Loire Blue

I also get the same smell. I'm pretty sure its the FBH. It comes on automatically if the temperature is under 15C and does a purge after the engine is switched off if it ran for less than 20mins. This stinks out my garage.
At least I am assuming this is the cause of my diesel smell.  2012 5.0L S/C

I would say its the FBH, it kicks in at all sorts of times and the smell is pungent and revolting, a really thick acrid diesel exhaust smell.

If the smell is raw unburnt diesel then you have a leak. Discovery 4 HSE
