Thermostats need to be changed for correct operating temperature of the engine.

Yours is sitting at 68 when it should be between 80/92

Very simply you can terra clean/change every part in and around the engine with faulty thermostats you will 100% have DPF problems

The car will not regen.

As said earlier easy diy that U can do yourself take roughly 2 hours and about £100

Has anyone had this problem, Does anyone know who does DPF cleaning around East London.

Read the thread on archoil ar6400-d, probably a cheaper way to try and sort out your issue before going for a full specialist clean

Unfortunately it seems he has already paid for a terraclean before sorting out the root cause of his lack of regeneration - the thermostats.

I also swear by the Archoil products

I would say the Thermostats are 1 of the most overlooked parts on our 320/335d cars.

The fact you have to go into a hidden menu to see what's really happening does not help.

For me personally it's not a huge issue due to the mods I've done to my car,

I've got rid of Egr thermostat, DPF completely, EGR,EGR Cooler, Swirl flaps, all the things that can kill our engine or make it very unreliable.

Not to mention the breather, and regular oil, and fuel filter Changes.

In my experience preventative maintence on these cars is a must for reliability,

thats my opinion anyway for what it's worth,

His DPF has plenty of life left. Ash mass is only 18g????

I don't understand why people want to remove DPF. At the end of the day it's a important piece of kit which helps reduce harmful emissions.

Since Feb 2014, if a DPF has been removed and spotted by a tester it would be an MOT failure.

All anyone needs to do is make sure DPF regens by keeping an eye on things like stat temps, DDE fault codes, fuel level etc.

[Thermobaric]

Should be illegal to remove DPFs imo.

All the answers have already been given in this thread so I won't repeat them here. Diesel cars legally have to have a DPF fitted from 2009 onwards although a lot of manufacturers fitted them as standard for a couple of years before that.

[Digitalize]

2006 model wouldn't have a DPF as standard.

As said because your car isn't getting to 90c it won't trigger a regen, not sure even Carly could force it to.

Replace your thermostats and go from there.

[jharar]

I am going to speak to my local garage tomo to check how much they will charge to replace the thermostat.

I am not very doing this kind of things.

Nice one mate. Having done the job a couple of times myself it's 3 hours labour maximum and the stats are around £80 for both main and egr thermostats.

Be sure to get a couple of bottles of dpf cleaner to put in a full tank of fuel once the work is done then go for a long drive. The code should clear and you should get a regen. Good luck.

Going to take my car later to the garage for thermostat..

pics from yesterday after driving the car for around 20 mins on motorway.

Just to add to everything that's been said...

Make sure your garage uses BMW parts, from a dealer ideally.

If you use OEM or anything other than the genuine stats the chances are you will be changing them again in a month or two.

And my dealer supplied stats lasted less than 2 years......

[jharar]

Update......

Got my Thermostat & Egr Thermostat fitted , picked the car up from the garage straight away went in the hidden menu to check the temp, driven the car home it went up to 87, took the car for good 30 miles drive on M25 hopping DPF will regen, but no luck at all..

I dont understand what to do now.

Changed all the things still no luck , Feel like to burn it..

[Digitalize]

Are you 100% sure your car has a DPF? You haven't actually posted the icon that comes up, and it's quite similar to the cabin filter icon.

This is the DPF icon

If it's not regening there is a reason why. If you don't have it, invest in Carly and see what fault codes you have.

The DPF will not regen with certain codes present. The coolant temp is only 1 of several conditions for DPF regeneration.

Off top of my head:

Coolant temp >75c
Exhaust Temp over a certain temp
Travelling at 60kph or above
More than 10L of fuel in the tank
Certain DDE fault codes not stored

Also, you say a 30mile drive but on which road type?

With your DPF blocked you'll only achieve regen on a motorway / dual carriageway travelling at a constant speed.

You could also put in some DPF cleaner into the fuel to help.

If it's still not regenerating with the above conditions met then request a regen via diagnostics. Carly can do this for an extra in app purchase.

Hope that helps.

Hi

Yes i do have the DPF error coming up pic with the yellow.

I have driven the car on motorway approx speed 60-70 mph for good 40 mins.
I tried with Carly to regenerate, But no luck..

Error's are

480
481

[jharar]

DPF error...

[Digitalize]

Okay, was worried you were confusing the two as they're similar icons with very different meanings.

If you've tried everything you can and it still hasn't worked, I'd probably just remove the DPF, there was no legal requirement for the car to have one in 2006 so you'd almost definitely have no MOT issue.

At least so far all you've done is a Terraclean and thermostats which were broken anyway, but they would have caused the DPF to not re-gen on it's own, possibly have been broken for a long time and it's killed the DPF.

Unless your MOT is about to come up I'd leave it for a bit, some long motorway trips or hard driving might help clear it, car might clean it up on it's own. Not sure what a DPF cleaner could do, worth looking at though, or talking to an independent specialist.

[jharar]

My MOT is end of April 2017..

In case if I get it removed, what if it fails the MOT, I will be screwed..

[BMW_fun]

As somebody wrote before, there are certain requirements for regeneration:
The following conditions must be fulfilled for a regeneration:
- The coolant temperature must be in excess of 75 °C
- the exhaust-gas temperature before the diesel particle filter must be greater than 240 °C
- there must be enough fuel (fuel reserve indicator light is not lit up). Whenever the reserve lamp lights up, the regeneration process is suspended.
- no fault codes from the air mass system, exhaust emission system and sensors must be saved in the DDE
- The fault codes 480A / 245700 (from F01) and 481A / 245800 (from F01) must display the status "currently not present"
- Constant driving speed above about 60 km/h (approx. 38 mph). The optimum speed is about 100 km/h (approx. 60 mph).

There are two kinds of regeneration:
Continuous regeneration:
This form of regeneration takes place during normal driving. At exhaust-gas temperatures of between 280-350°C, continuous regeneration takes place in the form of a slow oxidation process. The soot particles cannot be incinerated until the exhaust gases reach the required temperature.

Periodic regeneration:

Periodic regeneration is performed automatically by the DDE after no later than 1000 km (600 miles). On vehicles with many short-distance drives, periodic regeneration already starts taking place after just 400 - 800 km (250 - 500 miles).
For regeneration, the intake air is reduced by the throttle valve. One or two post-injections are performed. This increases the exhaust-gas temperature to about 600 °C. The soot is incinerated with the residual oxygen.
The periodic regeneration is performed at all speeds. The most efficient method is regeneration at a constant speed in excess of 60 km/h (38 mph) over a period of 20-30 minutes.
The DDE calculates the time for periodic regeneration from the following values:
- average distance travelled
- average driving speed
- temperature in the diesel particle filter
- values from the exhaust gas pressure sensor.

Frequent short-distance drives and urban driving cause the diesel particle filter regeneration function to work less efficiently. Longer, extended and insufficient regeneration triggers the fault entry 480A. As soon as the fault is saved, regeneration is then no longer possible. This function is inhibited.

If the diesel particulate filter does not continuously regenerate itself and the exhaust gas pressure continues to rise, the fault code 481A is also entered. The Check Control message "Diesel particle filter malfunction" appears on screen.

Once faults 480A / 245700 (from F01) and 481A / 245800 (from F01) have been saved, drive the vehicle for about 45 minutes at a constant speed. In addition, switch on electrical consumers to keep the exhaust-gas temperature between 280-350°C. That enables continuous regeneration to take place, the exhaust backpressure drops, the faults are remedied and the following status message is issued: "currently not present". Now, normal regeneration takes place automatically.

Well yeah, but a DPF is hugely expensive to replace if it is the issue.

Find a specialist near you and see what they say.

Have you tried going for say an hour motorway drive and then forcing a DPF regen? It might not have worked before because of the low coolant temperature. You'll need to drive for quite a while in these ambient temperatures to make sure everything is hot enough.
