Anyone have diagrams or can tell me where the vacuum pipes for the brakes are routed? At least this way I can check them all. I just wonder if where all the manifold, pipes and wires are routed, one of the vacuum pipes got disturbed or trapped when everything was replaced. I know what I'll be doing at lunchtime tomorrow!

It's at the front? Ok, I didn't realise! they are usually at the back, I stand corrected!! Should be easier to see the wires then hopefully. I thought I was being paranoid but my brakes have felt a little different but I thought that may be because of the new pads bedding in. They work fine but sometimes it seems the pedal feels a tad different, sometimes harder and sometimes a little softer. You are worrying me now! Maybe I should get someone to have a look. Mike |

As JSW says- It's at the front.
I saw a posting somewhere regarding that pulley- I think it may be a composite item (as in harmonic-balancer style) and if it is on the way out then one part will wobble excessively or randomly, causing an erratic signal to the CPS. It may not be obviously worn out, but worth checking. |

Thing is, it's at the front of the engine, not the back. I think the glovebox comes off with just a few screws, so might well be worth whipping it out and seeing what you can hear. Do the brakes feel any different? |

Cheers for the diagram, as I thought, the sensor is at 10 o'clock but a bugger to see. As for the hissing, when I got to work the other day I put my head down in the passenger footwell and the hissing sound seems like its coming from behind the glovebox. I thought at first it may be the speaker hissing but I pu my ear to it and could hear it coming further up inside the footwell. I cannot get my head far enough up inside and when I open the glovebox it doesn't get any louder but it's definatley coming from around that area. I can see wires behind there but no pipes. I have had the bonnet up when idling and I cannot hear anything different from before I had the manifold off. I notice there is a master cylinder on the bulkhead which I assume is for the brakes? As the brakes are servo assisted, could it be an air leak from here as it's in the right area. I haven't had a listen in this area under the bonnet yet as I've only just thought of it but I will and see if I can hear anything down there. Confused! Mike |

Mike have a look at this
http://www.e38.org/e32/M60EngineSpecs.pdf The crankshaft position sensor is part 16 The hissing is weird! Crispy voiced my thoughts exactly - as you've had the manifold off it's bound to be a vacuum leak - but I would have thought it would be audible under the bonnet. Just for a double check you could try spraying brake cleaner around and seeing if the idle picks up?... Edited by jetsetwilly2000 |

It's definatley not refridgerant because my aircon has been empty for about 2 years now! I've had a look for pipes. I can see vacuum pipes on the engine side but nothing in the footwell or glovebox. The car seems no different than before so whatever it is doesn't seem to be detrimental to the performance or running of the engine. |

Hmmm... you'd definitely hear it with the bonnet open. Well I'll have to have a look at mine tomorrow and see if I can find any pipes around that area. Also I think refridgerant is pretty nasty stuff so you don't really want that leaking into you passenger compartment :) |

Well it was a thought of mine but if it's losing vacuum, it would more than likely run really rough. You also cannot hear it when the bonnet is up and you listen in to the engine!! |

The crank sensor reads the teeth off the flywheel so definatley down the back. I did have a look today and I think I can see it on the opposite side to where I said, more like 2 o'clock rather than 10. I can see a shielded wire going down to about that area. On another note, I had a fiddle with fuses and the LKM module as well as relays and plugs around that area. I basically replaced a few fuses on the lights and re-seated the LKM and all the relays. The problem didn't re-present itself on the way home. It didn't do it on the way to work either but then I didn't have my lights on which seems to be the common denominator. I guess I'll just wait and see. I have heard of clearing fault codes can sometimes clear faults too. Perhaps it's worth a try too. Still can't identify the hissing sound though. Weird! Mike

Regarding the hissing sound - from what you describe it sounds like a definite vacuum leak to me. When the throttle's closed the vacuum's at its greatest, so the hissing sound would be loud. Flooring the accelerator will take the vacuum away and so the hissing sound would disappear! I hope I'm wrong, but from what I've read in the past the intake manifold gasket makes a loud hissing sound when it's leaking and the noise could well be coming in through the firewall. As for the electrics, as others have said I still it would be best to just get someone to plug the car into a diagnostic machine and get it all reset and checked out. |

Maybe this is what you meant, but I'm sure the CPS is down the front of the engine somewhere - have a poke about round the pulleys. I remember it being pretty easy to spot.

Tail gate wiring loom wearing at the hinge? Poor battery condition can throw up a lot of weird electrical faults. How's the battery?

Mike happy to see you got the car back on the road Reference the warning lights message, I had a similar problem on my 1997 E39 touring. It would throw up "check fog lights", "check brake lights" when they would be working. Mine would normally come up whilst driving the car throughout the journey a couple of times. Also it would make a "bong" sound when i'd switch the car off. Like yourself I checked the lamps and everything was fine. I had a mobile mechanic come and and connect his diagnostic machine to the ECU. He called up the faults and all the above where listed. He asked me if I was getting the "bong" sound when i would switch the car off. I confirmed this with him and he proceeded to clear the faults. He done a through check of the faults and once the car had been reset it ran fine. Since then, touch wood I havent had any more electrical faults. What i'm trying to say is that if you havnt already done so, get a mate to check your ECU for any fault codes and it may be a good idea just to clear the ECU from any non related faults and see if that brings any joy. Its the cheapest place to start. The electrics on the Beemers dont improve with time either. A mate of mine who works for BMW still says they get loads of E46, E60, and later model cars comming in from customers complaining of cars syaing there brake lights arent working when infact they do. Dodgie contacts or something he said. Sorry for the long reply and again if this hasnt been any help. Imran. |

As a few of you have read, I recently had a few jobs done on the car to get her through the MOT which has now passed thank goodness! But I have a couple of new issues which may be as a result of having the engine loom unplugged and the intake manifold off as well as various vacuum, breather and fuel pipes. One thing I have noticed since everything going back together is a hissing noise inside the car coming from the front passenger area behind the dashboard. The weird thing is, when at idle you can hear it clearly but it seems when I accelerate, the hissing noise gets less the harder I accelerate! so if I pull away gently, the hissing noise quietens slightly but if I floor it, the noise completely disappears. I cannot smell anything strange so I'm not sure it's a gas leak from the aircon (but the system is empty and doesn't run anyway) the only thing I can think of is some kind of vacuum escaping? I cannot fathom out what might be there that would use a vacuum nor can I feel any difference in performance (suggesting no loss of vacuum) or anything different from when it first went in. Also, second issue, I did have a warning come up a few times intermittently which was DIP BEAM - LICENCE PLATE LAMP - TAIL LIGHT - BRAKE LIGHTS. Some of these came upon their own, mainly the licence plate or brake light ones but I did also have all at the same time a couple of journeys. I only had the brake light one come up yesterday and today. Before I left work this evening, I changed the brake light bulb as it seems I only get the problem after pressing the brakes but not always straight away. I thought there may be a dodgy filament that was back feeding and causing a bad signal bringing on all sorts of issues. Both bulbs looked a bit blackened and the filaments looked burnt though they still worked but I replaced them anyway. Half way home after several presses of the brakes, the BRAKE LIGHTS message came up again but when I had a car sitting behind me, I pressed the pedal several times and I could see the red glow coming on and off so I know they are working. As the rear of the car hasn't been touched and the problem has only been since having everything at the front apart I'm wondering what could cause such a thing to happen. All pointers and suggestions welcomed please! One final thing, I want to replace the loom for the crank sensor from the plug at the sensor right back to the pins on the ECU plug. I have asked a guy at BMW and he said he'll need a part number off the plug to match it up? Sounds bizarre to me because I can look terminals and pins up for our vehicles though I have had a look on realoem and come to the same conclusion. Would anyone know or know how to find these part numbers without me having to take the plug apart? Also before I go searching, anyone know where exactly the crank sensor is on the M60 engine? I have a feeling it's at about 10 o'clock if you had the engine out and flywheel facing you? Cheers Mike Edited by 540 V8 |
