Guys
Would appreciate some feedback on the following DPF issue on a E60 535d. I have been monitoring the I drive service schedule which was advising c20000 miles on the DPF. As if by magic it referenced 120,000.miles this morning and which I thought might have been reset in error by my local indie who was clearing some brake light fault codes during the week- on drive back tonight I got a yellow engine warning light with a increased emissions warning " Fault affecting emissions have problem checked by BMW" The exhaust note sounded a little odd and definite burning smell around car when I parked up. Does this all sound like a new DPF is required?
All feedback appreciated.
Thanks

You can reset the time to service yourself with a combination of button pushes so quite possible it was reset by your mechanic.
However, the warning comes up if it detects an out of parameter flow equilbrium in the dpf - too much back pressure.
The car will attempt a re-gen, if you are lucky it will go away, if you are unlucky it will limp mode the car when it gets really blocked.
new DPF is £1200 ish, as mentioned you can have the DPF "cored" ie. the internals removed and the original DPF box re-welded - but you will need the regen function removed from the in car software. £3-500 for the job.
So depends on how long you are keeping the car.
When mine started showing signs of blockage I sold it.

Check your thermostats, there are 3 I think, and if they start palying up the car doesn't get to temperature, and the D{F will only regen when up to temperature.
Many who have been told they need a new DPF change their stats, it then regens for the first time in months and is good for another 50k miles.

I have a 09 E60 520d m sport and got the dreaded high emissions light on 96k miles, was expecting it around 114k based on other forum posts however thinking back a change of job and more frequent shorter journeys probably led to the clog up. Looked into having the DPF removed but more and more people warned against this as apparently makes the car smoky and also MOT testers getting wise on the practise. I tried a local garage who used some sort of DPF cleaning stuff in the diesel tank - don't bother it does nothing !
I was about to bite the bullet at invest the £1200 on a new DPF then I stumbled across terra clean which is primarily for removing the carbon deposits from the engine to make it more efficient but some terra clean dealers also offer a DPF clean. Admittedly their website is terrible and you resort to picking post codes near by to try and find a dealer offering the DPF clean but it was worth it. No need to remove the DPF they run the terra clean fluid through it, the garage I used had the car in for about 4 hours they fully cleaned the DPF and I also opted to have the engine cleaned and de carbonised at the same time all in was about £350. They then ran a forced re gen and took it for a run on a regeneration drive keeping the revs above 2.5k for 15 mins to burn off the last of it.
Worked wonders 3k miles later and no DPF warning lights the engine decarbonising worked wonders too I now get 47 mpg previously never got better than 40 mpg which dropped to low 30's when having the DPF issues.
Their website is terraclean.co.uk I'd definitely recommend them

Thanks all- I have booked it in for a diagnostic next week and will update the thread then
That will probably just tell you what you know already, you just have DPF issues. I would check your temperatures when driving.
Search google on how to do it, just a few button presses to show the hidden menu.
if your not seeing over 90ºc that is what you need to address before spending money elsewhere.
Thanks for the additional replies so here is the update after a trip to the dealers today- not sure whether to laugh or cry but here goes-my warning light was due to an air mass sensor fault linked to a split hose on a turbo boost pipe from inter cooler to the manifold. Didn't really have time to discuss in detail today but they are not totally sure that they have fixed the problem but no repeat of fault following a sharp drive home. The other more than slight concern is that they reckon the car is a little down on power- it doesn't feel it though and they weren't totally sure that this wasn't a misreading on their computer ! Car itself looks fantastic but looks are skin deep...oh and I will need 2 front tyres very shortly ! Thinking it might be time for a change ...

First and only post is a testimonial to a cleaning product, maybe I'm wrong to be suspicious.
Can be suspicious if u like! First post as I went through same issues with DPF, and actually also had a torn turbo boost pipe so sounds a common fault. i spent hours searching forums for a better solution than paying £1200! Just thought I'd share to try and help.. Take it or leave it!As has been said above, before doing anything else get your main engine and EGR thermostats replaced. Good to hear that the car is working ok now but for DPF peace of mind the car needs to get to the correct temperature before starting a regen no matter how far or hard you drive it. I found this out the hard way, changing the thermostats is the best way of ensuring your DPF will last as long as possible.
If or when it does block then they can be successfully cleaned, any good independent worth their salt can do this, a brand name is not required!
Good Luck

They are around £75 for both the main stat and the EGR stat from cotswoldbmw.com.
You are then looking at around an hour to hour and a half to fit them, so £60-100 ish.
You could do the EGR one yourself, it really is dead easy......
