Take it to a recommended independent garage, but don't take it to a Nissan stealer. Not going to be a cheap Christmas for you :crying:.
As for taking the DPF out to clean?


Still it's fixable :wink:.

there are places local where they clean the dpf once it has been taken off dipped in a bath of chemicals for about 100 pounds to 150 pounds but problem is the dpf e12 is at top near manifold connected to manifold what looks like flexi pipe and one garage said it will cost for just removing the dpf 300 pound for labour

I'd guess that if you get the car up on ramps you'll soon see what needs to be removed as it's inline from exhaust to ex' manifold.
I've seen new ones on offer on ebay but it's generally a rotten job for a home mechanic..

Own regeneration for free. Before you start, place something on your drive underneath the engine, (I read this somewhere)just in case anything (liquid)drops from the engine. Start the engine and put a block under theaccelerator peddle with a house brick on top to hold the peddle down. This will take some experimenting of the size block required under the peddle to allow it to be at a constant 2000 RPM. Do this for 30 minutes or until the DPF light goes out. Sod paying a Nissan dealer £300.00 to do the same thing
. 2000 RPM is only 1200 RPM over tick over, so it's not really revving the balls off the engine.
If you read the hand book they recommend you travel at 37.5+ MPH. (It don't say what gear to use, but I would guess 4th gear),where safe to do so, until the light goes out. But a block and a brick will do the same thing while your having a cup of tea
When we bought our only diesel with a DPF we were concerned with the frequency of the regens, they were taking place every 250 miles as regular as clockwork, they plugged in the laptop and were able to confirm this. The dealer did not have a clue since ours was the first car they had delivered with a DPF and the tech help they could access was in their words "useless". So they decided to carry out a forced regen (warranty) so they knew it was clear and then monitor the frequency or the next few regens and take it from there. I stood outside the workshop whilst it was done. They plugged in the laptop and started the engine. the laptop took control and over the next 20 minutes varied the revs between idle and about 2000, increasing and decreasing over the time it was plugged in. Once it was completed it allowed the engine to cool down before alerting the technician to turn off the engine.

Far safer and more scientific than a block and brick plus I doubt constant revs would do anything since our was carried out with the computer varying the revs. Just imagine the carnage if something slipped with the vibration and you got max revs up to the limiter whilst you were out of the car.

On our car with DPF there was no specific DPF light but an orange engine light indicated that you needed to drive at the required revs or speed for about 20 minutes to force a regen and hopefully clear the light. If that did not work or the light turned red the handbook clarly said to take the car immediately to a dealer to get a forced regen carried using their management software. The next sentence was also clear, ignore the light and the dpf will block beyond what can be cleared out and will need replacing.

I suggest you get the car to a garage that knows what they are doing as soon as possible. You are inevitably going to get a big bill but the longer you delay there is a 100% certainty that the bill will get bigger.

How to remove dpf
Removing the DPF for cleaning is pointless unless you go to one of the specialist companies that now exist. The back street garages that simply pressure wash them are wasting your money and breaking the law since any material they remove and wash down the drains is toxic.

If you intend removing the PDF expecting it to extinguish the light on the dash you are also wasting your time. The ECU would need reprogramming to ignore the fact no DPF is present and that leads to another more serious issue.

Cars that have had the DPF removed or tampered with are now and instant MOT failure. Since a car with no DPF when one was fitted at the factory would not pass an MOT this renders them illegal on the road.

Unfortunately there is no cheap fix. Any money you spend on such a fix will be wasted. Put it towards getting the issue diagnosed correctly and fit a new DPF if its needed.

" i know a place where they dip them in chemicals"
If i were you i would take the car to the company you know of and let them do all the work, it may be a few more quid for you but it will also be a whole lot less hassle.
