So guys thought I would check back in after a while as it's now been close to 9 months since I had the DPF removed and I've done approx 10k miles since then with a lot of mixed driving. Update: 1. Car still running fine 2. I have lost some MPG on a long run used to get 44-66mpg now only get 42-44mpg 3. i am still getting puffs of somke and i think this is because the DPF emulation bit by ecuflash.co.uk was not done correctly so I think the 5th injector? and fuel mix is not right or they have not removed dpf regen code, so usually when cold or engine is clod i am getting puffs of smoke noticeable But as the engine warms up and I hit motorway speeds these go away fro long periods and only come back at lower speeds after a fed days. 4. Anyone know if someone in Manchester can do a check of the DPF emulator/files used as I think this could be fixed by someone who knows what they are doing. Have phoned ecu flash 3-4 times over last few months and always been promised call backs but never happened.

Hi All/Shazy Just a quick update as I haven't been bale to get back and update. So been close to two weeks since removal of DPF and so far the car is running fine. As mentioned in my post above did have some large white smoke and this lasted for approx 3 days, once I’d run through half the tank with the BG244 cleaner in this suddenly died away to not being visible from the car or appearing at lower speeds/revs at all. Had my wife drive behind me and she confirmed small puffs when I put my foot down or at higher revs, not continuous but regular small puffs, again not visible form in the car unlike the first 2 days when large white puffs were visible, again I believe this was the carbon deposits/blockages being burned off from the fuel/exhaust system/manifold as identified by Lexus when they inspected. Power seems smoother and more evenly delivered, power it's self seems the same but fuel mileage a bit better but have not done a long run yet. So fingers crossed so far so good since removal have done approx 470miles of local driving and a few short motorway runs.

Well guys here is the latest. Lexus GB basically said exactly the same as the dealer and refused to budge or help in any way. So I just was not willing to pay 1400 to Lexus for this as I feel the part should not have gone so early. Decided to get a DPF removal from ECUFlash.co.uk £600 and that was done last Fri/Sat in Sheffield. Picked up the car Sat Am and added a tin off BG244 as I was aware that the would have removed DPF added a steel pipe and fitted the emulator unit, but from what Lexus said there was Carbon build up so wanted this to help clean the engine, Drove it back to Manchester via the motor way so circa 70 miles and for the first half drove normally and had no issues, then I switched to a slightly harder driving style to try and heat up the exhaust temps to allow the BG244 to work in the exhaust system and noticed some white smoke being generated fro about 10 miles then stopped. Assume this is the BG244 working and cleaning burning of carbon deposits formed. Or should I be worried? The garage assures me it would pass the MOT but reading up it seems DPF removal does mean a bit more smoke then cars with it so will see what happens. Car seems to drive a bit smoother now after having done about 200 miles, have had no problems even at cold start-up today started first time and just feels a bit smoother so I guess the BG244 is working, but again at higher revs will get a bit of white smoke for a while, then when I slow down smokes goes away. Will let you know how I get on after a full tank of BG244 has been run through as have only used a 1/4 of a tank yet.

Thanks for the info Mudassar, still not heard back from Lexus GB assuming the dealy is due to bank holidays. Have been reading on oil for a few days now and am going to replace it i think to be safe, found this link really useful to understand ACEA differences. http://sas-origin.onstreammedia.com/origin/lubrizol/EOACEA2009/RPTOOL2010Dep/rp/pc/index.html Will let you know what Lexus say.

So still awaitng a response but think i will go to http://www.ecuflash.co.uk/ who i spoke to today they can do dpf removal with a module fitted to handle the ecu lifetime warranty and £600. In yourshire, had anyone used them before?

Thanks all for your responses so the latets chapter is as follows. Lexus have carried out diagnostics and concluded it is the DPF filter, they have also advised that the manifold and a vacuum pipe need replacing as well as they are blocked with carbon, so they have given me a quote of £1400 to have the work done (discounted from the £1800 it comes to based on list process for parts and labour). I am just a bit stunned that my 47k Lexus which has had a service every 10k miles give or take a few thousand can suddenly need so much work and has carbon built up in it. They did try the regenerate the filter for 2 hours but have advised it's failed and a replacement is only option. The service manager at Lexus Manchester did also raise a customer relations case in to Lexus for me to see if they can help at all as she was a bit sheepish about the fact that it needs this at 47k miles so it is a 57plate and out of warranty now but still this is the kind of part you expect to last the life of the car, and my driving patter is 3 days urban and 2 days i do a 400 mile round trip to head office so the car has had plenty of opportunity to hit high speeds and hit temp requires for passive regeneration. I have no e-mailed the Toyota CEO a complaint letter which he has passed on to a manager in customer relations to have a look at and I will let you know what they come back with. Worst case if i get no help then i will look at removing DPF, Alicja thanks fro the link does anyone know of a place in manchester tht do DPF removal and a smoke test to gurantee MOT pass?

Thanks for the post mickmate. So this has also happened to me on my 57 plate is220d yesterday, drove it for about a day stop/start and it only actually went in to limp mode once in 3 trips. Whats worrying me is that I had actually done a 200 mile trip from London to Manchester so was driving in 5th at about 2.5k revs all the way home. So surely should have had enough temp to burn of the soot and clear the filter there was no warning light when i parked up about 7pm, then took the car for a 5 min trip 2 hours later and got the light? Have got my garage to clear the egr valve and also they have run diags and found the DPF error code but said it was cleared when they reset and so have suggested i drive it for another week. I have recently changed the oil using shell helix and I'm just worried if this may have caused it as i brought it online and it complies with the ACEA B1 spec as given in the handbook, but upon reading the oil bottle closer is says designed fro all diesel engines with out particulate filters? Can the oil have caused this as I've done about a 1000 miles since the change where as for the 6 months before this I've done 5k miles with no problem Any ideas/thoughts welcome.
