Question about BMW 530D!
I have just been looking at a 530D tourer at a garage near me. The car has just 45,000 miles on the clock, which is low considering it is vintage
2005. The car looks pretty tidy (apart from a few marks and signs of wear - normal for a 7 year old car). However, when we went to take it for a test
drive, it initially had a bit of a lumpy idle, and there was quite a strong smell coming from the exhaust.
Before we took the car out, the dealer said he was very happy for us to take it out, because it had not been driven for a while, and up until then it
had only done short journeys/been moved around the forecourt. He also said that he had not done any work to the car, but he would be given it a full
service this week, so we could come back and view it again after that.
So Locostbuilders - share your wisdom with me....! Would it be something to worry about/run away from, or have I just not been driving diesels for so
long now that I have forgotten that they are not as smooth/smell free as the silky smooth 6-cylinder petrol BMW lump we have in our 3-series...?

Dpf kicked in straight away?

That was another suggestion from the dealer - I wasn't sure if they only kicked in on a run rather than just after start up...

I've got a 2001 530D auto it's a little bit noisey at idle but smooth as silk to drive at 200k as is my brothers manual at 270k

A friend had an older 530d. It was always smooth as silk and never smelled any more than any other diesel.

There are a few conditions that have too be met for the dpf to regen.
Over 10 litres of diesel in the tank.
Coolant temp over 79 or something degrees.
Average speed of 40mph over the last x amount of miles.
Seems unlikely it regend if it had just been moved around a forecourt ,
Look into accessing the hidden menu to check the running coolant temps as chances are it will need both stats changed, such a common problem and badly
effects mpg
Also watch out for cracked exhaust manifolds, very common on early e60 and e61s
All said and done, I love mine, wouldn't be without it.

The range left was showing as 14 miles, so I don't think it could possibly have satisfied those DPF conditions....
I am wondering if an injector is failing, as it seems lumpy idle (up to 1500rpm) is a symptom of a failing injector.... But on such a low mileage car,
it seems odd. Could it just be that it hadn't been run for a while, and hadn't had a proper run for even longer?
The golden question, would you go back and take a second look?
This is the car in question FYI.

takes +500deg to regen a dpf (unless its a pug etc with regen fluid) 530d's are silky smooth, although all diesels will be a little bit rougher
on warm up. on the move you shouldn't even be able to tell its an oil burner.

Did it smell of fumes in the cabin?
Mine stunk in the cabin and was lumpy when the manifold was cracked.
If the dealer is willing I have the full bmw software and cable to plug it in and check all the systems.
Can also confirm if the DPF is regenerating properly.
Looks a lovely car. Exactly the same as mine but mines grey

Get an injector leakdown test done , most likely excessive leakback on one injector which you only really notice at idle .

Thanks for the offer Gaz - I will bear that in mind. I want to see how it is after it has been serviced. I checked the oil as part of looking around
it, and the level was spot on, but it was quite black, so a full service can't harm...
My biggest worry is that I buy it, and after the 3 month warranty is up, one (or more) of the injectors fails - a friend had this, and the cost to put
it right was the best part of £750!
It did feel silky smooth on the drive, and the smell was much better (but not gone) by the time we got back (15 minutes of driving). I think there is
a certain smell to a diesel car exhaust, but my mrs doesn't think it smelled normal...

Sounds like it needs a good service including fuel filter, fresh tank of fuel and really good blast down the motorway. The mileage is, as you say,
low for the yer and probably means a short trip life so far, which diesels don't thrive on.
I'd try and get the dealer to do the service and let you retest. Maybe offer a deposit as encouragement.
Well worth a pun IMHO.

You are spot on! The last owner was living in Scotland, but then moved to central London, so my suspicion is the same as yours, that is has seen its
share of short/slow journeys. I think I will give the chap a call later this week for another test drive...
