    Recommended Garages/Services/Suppliers

    This thread seems to be almost dormant, which is a shame. I guess many of us must use dealers and independant specialists - if anyone feels in a position to recommend anybody, I'm sure lots of us who are looking for a good service workshop would be grateful - whatever area of the country they serve. I'd like some recommendations for Berkshire, please.

    INPA can't connect to all modules on the car

    Glad to hear you got it fixed, didn't take you long. Thank you for posting your solution too, it seems there are variations between BMWs, and of course any previous owner could have modified things (intentionally or not) so it always pays to check the basics.

    INPA can't connect to all modules on the car

    TBH I don't know how difficult it is to get to the Webasto; as you probably know, it lives behind the left front wheel on the E39 but I've never tried to get to it. If you can access it easily enough, yes go ahead and disconnect - but protect the connector from contamination with road muck and moisture, as these might also cause bus problems if they provide a low-resistance path between pins. In my case I removed the Webasto K-bus line from the X10116 star point located behind the glove box (Remove glove box first, it's easy). It is a bit of a fiddle getting the star point out of its plastic enclosure, but it can be done and then you can remove all the wires to isolate the faulty circuit. It's worth disconnecting the battery before poking about in there, then reconnect when you have everything safely apart. If someone can say whether the Webasto can be easily accessed under the wheel arch, you might be best off trying that route first, as you suggested.

    You are most welcome - but it was the input from others that enabled me to get to the bottom of it. Clavurion in particular put his finger on the K-bus being the common factor and encouraged a methodical approach, providing the factual information to help make sense of my findings. The diagrams on page 18 of the document he linked to were particularly helpful, I suggest you study these and identify the common factor in your faults. You may also like to know that in more than 18 months since identifying and removing the Webasto K-bus wire, I have had no electrical fault nor error message on the dash. The car has been completely reliable (touch wood) and it always goes to sleep. I left it unused for 3 weeks recently, and it fired right up when I returned; the battery had not discharged noticeably. If you need any further guidance on your fault, post the details and we'll do our best to help.

    Suspension height sensor - part number confusion

    Thank you very much Clavurion for confirming that -696 fits the front of your M-Sport. I'll order one with greater confidence now

    Suspension height sensor - part number confusion

    Right, I think I'm making progress. A thought was triggered by this discussion, so I've just been out and taken the back wheel off and looked at the E39 rear sensor. It has part number 1093700. This also does not reveal any useful information in RealOEM. However, I measured the spacing of the screws, and it is the same as the Mini front sensor I mentioned earlier (30mm). So I now think the Mini front sensor 1093698 is equivalent to the E39 rear sensor 1093700 (arm orientation looks about right too). These parts are both now superseded by 6784697. My E39 front sensor (1093697) has 33mm spacing between screws and a different arm orientation. I now believe that the RealOEM diagram shows the rear sensor on the right, and two different front arrangements in the left two diagrams. Therefore the current E39 front sensor is 6784696. I checked this theory by searching further, and the Febi Bilstein site lists the following: Febi part 32328 is equivalent to BMW 1093697 (my E39 front) and BMW 6784696 (current part number) Febi part 36921 is equivalent to BMW 1093700 (my E39 rear) and BMW 6784697 (current part number) and BMW 1093698 (my wife's R52 Mini front sensor). So bottom line is, I need 6784696 for my E39 front replacement (or Febi 32328). Based on my findings, I think I can say that 6784696 and 6784697 are not interchangeable because they have different mounting screw spacing (30mm vs 33mm as above) and the arm orientation for the active segment of rotation is different. This means that even if you modify the bracket to mount the sensor, it won't work because the internal Hall effect device will be in the wrong place when the arm is connected to the suspension linkage, and you won't get the correct output signal. Apologies for the lengthy post, but I hope this helps someone in the future. None of this is clear in RealOEM, and even the BMW dealer didn't know which part I needed (-696 or -697). After all this, I hope the part fits and works when I get it!

    Suspension height sensor - part number confusion

    A front sensor is fitted if you have xenon (HID) headlights. The controller monitors the suspension height front and rear to determine how high to aim the headlights, and it adjusts the aim dynamically as you drive using motors. The rear right suspension sensor is a double unit with two sensing elements, one for the headlights and the other for the rear air suspension.
  8. Hello, I have a 2003 E39 M-Sport Touring with the lowered suspension (Option 227) and xenon headlights (factory fitted). I've diagnosed a faulty front suspension height sensor so I'm trying to get a replacement. The part number marked on the old sensor is 1093697. I can't find this on RealOEM. RealOEM shows part 37146784697 as being the correct current part, and I noticed it shows the same part number for my wife's Mini. So I thought I'd take the one off the Mini to see if it fixed the problem on the E39. However, I found it was different in two ways: the mounting screws were on a different spacing, so it didn't fit the bracket on the E39; and worse, I had to rotate the sensor's lever arm backwards in order to get the sensor output signal to work - of course it would not then fit to the suspension link. The Mini sensor is marked 1093698. I've seen aftermarket sensors labelled with both 37146784697 and 37141093698, which implies they are the same as the Mini one and therefore different from my E39 sensor. Has anyone replaced the front height sensor on the E39 M-Sport with part 37146784697? Did it fit the bracket, and did it operate correctly?

    INPA can't connect to all modules on the car

    I thought I'd post an update in case anyone is interested. I've now run the car every day for more than one week, and I can report not one single error message or malfunction has been detected. Since I've disconnected the wire from the K-bus, which I believe is the one from the Webasto auxiliary heater, all modules known to be on the car can be accessed through INPA and I've successfully cleared the faults that were present. I have never been able to access the K-bus modules previously, and the Webasto has never worked, during my ownership. It seems the faulty module affecting the K-bus communications has altered somewhat over time, since the other K-bus modules worked fine until a couple of months ago. During this time, I've suffered various faults and errors which have come and gone. These included a frequent failure of the car to go to sleep (causing excessive current drain while parked); error message to say rear suspension is inactive; no rain-sensing wiper operation; occasional non-operation of the remote key to lock the car; non-operation of the indicator lights when locking the car; and probably some others that I've forgotten. Since disconnecting the Webasto from the K-bus, all of these faults have cleared and everything has worked properly all week. So if anyone is having wierd issued like this, first check your battery is good (mine wasn't so I replaced it) and then isolate the problem area and take a methodical approach to narrowing it down. Many thanks to the people who contributed to solving this problem, it's so nice to get in the car and not be confronted with error messages and boings from the dashboard all the time.

    INPA can't connect to all modules on the car

    Thank you Clavurion for this information. My car was built in July 2003 so I suppose it has no LWR. The only other thing I thought I might find is the SZM centre console switch. My car only has DSC and PDC on this switch unit, plus a Trafficmaster, and these all have dedicated control modules so I'm guessing that probably doesn't require an SZM. Anyhow, I now have access through INPA to all the modules I need; I've cleared my airbag fault and hopefully identified the module (Webasto) that was previously preventing the car from going to sleep. I've had a few other odd faults but now I've cleared the error memories I'll monitor things and see what problems remain, if any.

    INPA can't connect to all modules on the car

    Progress! I separated all eight K-bus wires from X10116 behind the glovebox and labelled them. Then I connected each one in turn to the wire from the IKE and ran INPA to look for the modules that I hadn't previously been able to see. Here are the results: Wire no. Module 1 IKE Instrument Cluster 2 EWS3 Immobiliser 3 Unknown - (no working module) 4 MRS4 Airbag 5 EHC Rear suspension 6 RLS Rain & Light sensor 7 IHKA Heater/AC control panel 8 ZKE3 General Module So then I connected all wires together except no. 3 and checked again that I could still read all these modules with INPA. I also read and cleared all faults stored in the modules. I noted that the IHKA reported a short on the Auxiliary Heater. Wire 3 presumably connects to a faulty module. However, there are four modules that I believe are fitted to the car, which I've still been unable to see in INPA. These are: LWR (Headlight Aim - car has Xenons), SZM (Centre console switch), GR2 (Cruise control) and the Webasto auxiliary heater. So I'll have to access the connectors on these modules to identify which one connects to wire 3. Does anyone have any idea why I can't see the other 3 modules?

    INPA can't connect to all modules on the car

    You are right. I have now removed the instrument cluster (IKE) and positively identified the K-bus line from there to the multi-way connector behind the glovebox. It was in fact the one I had disconnected, so the K-bus was isolated and therefore none of the modules was visible to the OBD port. Unfortunately I ran out of time and haven't yet tried INPA again. However, I've never in the past been able to access many of these K-bus modules through INPA, so there may well be another fault on the bus. I will take it step-by-step and try connecting the K-bus wires individually to the IKE, checking INPA each time, and see what I find out. Thank you again for your help. I'm optimistic that I'll make progress tomorrow.

    INPA can't connect to all modules on the car

    I think you're onto something here. I've decoded the modules listed on each bus in the diagram you referred me to and compared to the list of modules I can access using INPA. I've also searched for modules not listed to see which bus they connect to (K-bus or I-bus). I found that all the modules I can access are on the I-bus, and all those I can't access are on the K-bus. So it appears that I probably have a K-bus problem. I can't actually connect to any K-bus module. I have a high OBC cluster with widescreen. I have a Webasto aux heater, which seems to be a common culprit for K-bus issues. Also a Trafficmaster - can anyone confirm if this is a K-bus device? I've found a blown fuse near the battery for the Webasto, which has never worked in my ownership, so probably worth starting here and unplugging the unit behind the front wheel.

    Thank you, yes I will try this. There seem to be several people reporting favourably on Cableshack and they seem to get access to all modules, so I will give them a call. I just wanted to be sure I hadn't missed something fundamental first.

    Thank you. I don't recall seeing Functional Jobs or anything like it, but I'll check when I get home.
