Hi Dave, I left school at fifteen , that was 63 years ago so don't think a test is for me, to many senior moments. Don't laugh they'll come to you to. I may have made a breakthrough, fingers crossed. I have removed the manifold once more and when I had a good look at the swirl flap actuator and vacuum solenoid I noticed where the ingoing vac pipe enters the solenoid the spigot pipe had been glued in, looks like araldite. I removed the solenoid and tried sucking the vac pipe. I found I could both blow air and suck air through this pipe. I then powered it up with 12 volts and it was just the same so I'm thinking it will not hold a vacuum. I tried sucking the small pipe which joins the solenoid to the swirl flap actuator and it was operating as it should (turning the swirl flap rod)! what do you think? Regards Andy. P.S whoever removed the swirl flaps must have broken the pipe and glued it.

Morning Dave, the valve was new in the box! My god I never dreamt there was so many abbreviations, I won't be trying to learn these, I'll just refer to the list. Thanks for that. Andy.

Hi Dave, it was the pipe going to the EGR valve I was looking for suction and got none. I fitted a new pressure regulator but still no suction so I found a video on u tube on how to test the pressure regulator. I followed the instructions and the old one would appear to be faulty as it did not give the same results as per the video. With reference to the brakes they would appear to be perfect but I think I should start at the vacuum pump and work from there. Its a bit difficult to get the car up to temperature when the inlet manifold is on the bench. I don't know why BMW have to hide everything under it, I have even had to drain the coolant and remove a pipe to get at most of these rubber pipes. Also is there anywhere I can find a list of all these abbreviations like DDE , PCM etc and what they mean? Regards Andy

Morning Dave, I have the EGR off again and stood it in strong degreaser all overnight being careful not to submerge the diaphragm part. I have also ordered a Vacuum tool so I can test all the pipes. If the car is running there is no suction whatsoever no matter what revs the engine is doing so I need to find out why. I will have a look at Carsoft scanners as I certainly need to get something more in depth than Carly. Let you know how it goes. Thanks Andy

Hi Dave, I had a look at Foxwell and their stuff looked reasonably priced. I was unable to find anywhere that gave me much information about what level of diagnostics the different models were capable of, well none I could understand that is. I did however have a look on Trust pilot and the reviews about them as a company are diabolical. I got a new manifold pressure sensor and fitted it but still have EML. Regards Andy.

Hi Dave, thanks for that I will have a look around and see what they can do. regards Andy

Hi Dave, no worries I do appreciate your efforts its just me having senior moments more often than not now. I had a good friend who was a computer whizz and he said I was one of the very few people he knew who could confuse a computer. If you do have any ideas that you think might be around my level then please feel free. Regards Andy.

Hi Dave, I'm afraid I'll just have to go by the process of elimination. I appreciate you trying to help but 90% of what you are saying I don't understand. That other thing you sent has got about 120 pages and most of them are way beyond me . The diagram I can't read even with a magnifying glass. I checked the inlet manifold pressure sensor with my multi meter and when I start the car its showing 1.24 volts at idle and only goes up to 1.28 volts at 3000 revs so I've ordered a new inlet manifold pressure sensor so I'll see how that goes. In the meantime I'm going to take the manifold back of and go through the pipes again. regards Paneuro.

Hi, I had the diagnostics done and all he can tell me is it is EGR related! If he knows more than that he is not letting on. He is probably hoping I will give him the job of fixing it and then he can make some serious money. I can't blame him for that as he is in business and has to earn a living. I decided to have a go at checking the resistance of the oxygen sensor today after watching a few video's on U tube but when I disconnected it I discover it has 6 wires going in so it tried to find a wiring diagram for the plug. I did get a reading of 0.10 ohms between pin 1 and pin 5 if that makes sense to anybody? After trolling the internet for a couple of hours for a wiring diagram I eventually gave up. Maybe somebody on here will point me in the right direction. TIA Paneuro.

Hi Dave, with all due respect and I don't mean to be rude in any way. I have a multi meter and I would be delighted to check all these sensors if I knew what I was looking for. Its of little use you telling me to check the sensors if you don't tell me what or how to check them. Am I checking them for continuity? am I checking them for resistance? what resistance should they be ? etc. If I new that then I could come back and tell you my findings. Then we might be able to proceed to some sort of conclusion. I do have someone who can delete the EML never to return but I would rather get to the bottom of the problem and correct it. I am quite capable of removing the EGR altogether and getting it deleted but then how would my insurance company view that in the event of an accident? I'm sorry if I have given you the wrong impression but cost is not the most important issue but I would like it to be realistic. I do appreciate your help. regards Paneuro

Hi, can anybody say if there should be suction at the small pipe which connects to the EGR valve ? also at what revs does this suction begin? cheers Paneuro

Hi, I have a 2008 E61 530d and when I turn the engine off its like something venting air but only does it once. any ideas? Paneuro.

hi dave, I forgot to say the car has done 120,000 miles. Also meant to say I won't harass you any more. Paneuro

Hi Dave, if the vacuum pump was faulty surely it would affect the brakes? I renewed all the rubber vacuum pipes with the exception of the ones going to the engine mounts. I removed the inlet manifold and cleaned it out, also the EGR valve. I renewed the EGR pressure control solenoid. I then cleared the faults and the EML stayed out for Around 20 miles? Surely I must have done something right? I beginning to think I need help and not the car. cheers Paneuro.

Hi Dave, I forgot to mention my car is a late 2008 and is an LCI model. I took the new vacuum pipe of the EGR valve today and cannot detect any suction from it (the rubber pipe I mean) ? Am I right in thinking there should be suction there? The reason I asked is you mentioned I should check the voltage at the plug going to the new pressure solenoid I fitted but unfortunately I had refitted the inlet manifold by then. I have checked all the fuses in the glove box and they are all ok. cheers Paneuro.

Hi Dave, my car is a 3litre. Regarding the diagnostic program, The downloading and installing these things are way over my head, the only words I understand are the plain English ones but the other 90% of the computer jargon might as well be in Chinese. thanks Paneuro.

Hi Dave, when I first got this car the DPF light was on and I was told it was a pressure sensor on the DPF unit. I replaced it with a new one PT no 13627789219-03 but this made no difference whatsoever. It turned out it was the thermostat which was not allowing the car to run at the proper temperature. once I got the engine temperature up I forced a regeneration and all was well after that. It seems to me you just have to keep throwing expensive sensors at these cars until the fault is cured. Do you think the INPA/ISTA will be more specific in identifying the problem and if so where can I download it . thanks Paneuro

Hi Dave, are these 02 sensors on the exhaust side and how do you go about checking them? The air con works to a degree, I have re gassed it during the hot spell earlier in the year and 2 days ago fitted a used AUC sensor but it is still throwing up a fault 009C54 as before! I have also thought about these more in depth tools like inpa or ista and I do have a spare laptop that is unused but with my limited knowledge of computers I am nervous I might get myself into more trouble! thanks Paneuro.

Hi Greydog. ran a test today and the EML light stayed of for about 6/7 miles, then when I stopped and restarted it came back on within 20yards. I tried several times during the days journey (90miles) and every time it just came back on after a few yards. it just says the same as it did before. Exhaust gas recirculation control, control deviation. The air con again is as it was the first time but I will try cleaning the contact wires tomorrow. thanks Paneuro.

I will check again and let you know, I cleared it yesterday and it has not stored it. cheers Paneuro.

Hi guys, I need to be kept away from sharp objects or a box of matches. The dreaded EML has returned , think this car needs a new owner!!! P-ssed of with a capital P. Paneuro.

Hi Greydog, would these be vertical knurled controls, left one on /off and right one hot/cold ? if that's them I have them. I thought they just controlled the rear temperature! I'm still at loss as to why they are throwing up a fault? thanks Paneuro.

Hi, I was reading one post on here where Greydog mentioned motor stratification rear right and he was describing where it was located, I have been looking for this but can't seem to find it, could he possibly elaborate on this for me please Thanks Paneuro.

Hi guys, dragged the inlet manifold of and emptied a can of oven cleaner into it , then pressure washed it out and had a look, Then I went for the big guns, a kilo of caustic soda flakes followed by a kettle of boiling water and left it overnight, then another pressure wash. It would be interesting to know how much weight I removed but I did not weigh it before i cleaned it. Replaced the vacuum lines other than the ones that go to the engine mounts. Fitted the new turbo boost control solenoid and put it all back together. Erased the fault codes with Carly and all is fine no EML. the only fault I am left with is the air con one and I have a used AUC sensor coming from ebay. Fingers crossed that will cure the last fault code. Thanks to all who offered advice. Paneuro.

Hi, I think I have solved the problem. I removed the vacuum pipe from the egr valve but there was no suction there whatsoever so I traced it back to the egr pressure converter solenoid. I have ordered a new one which I think will cure the problem. I will also clean the manifold and the egr valve while its in bits. I will have a good look at the rubber pipes as well. hopefully that will cure my problem. thanks for everybody's advice and I will post the result when its back together. Paneuro.
