    My X5 has just come back from a garage, after a couple of Mot fault repairs -namely an inner CV joint boot, and a rear lower wishbone on the n/s front. They did a wheel alignment check after fitting the wishbone.

    On the way back home I noticed that the fuel gauge and the rev counter were not working, and also saw that the miieage display along the bottom edge of the dash was not lit either. There is nothing I can think of that would have been touched during the work, that would have affected anything electrical. I am taking it back later for them to look, but they aren't a BMW garage, and I guess they probably wont have the necessary gadget to diagnose what is wrong - it is a decent fair sized garage, so I may be pleasantly surprised - we shall see!!

    Can anyone suggest what might be the fault? A fuse perhaps? Or a dodgy ignition switch? All suggestions gratefully received !! Just in case they cant fix it!

    I have read up on ignition switches.....and operating the sun visor mirror has no effect on anything, the radio works, the horn works, and the wipers work normally. I am struggling to find anything listed in either the handbook, or the manual I have (Bentley) on what each fuse does, as that might well give a clue. I have filled up with fuel, so at least I wont be running out anytime soon, and I can live with the lack of rev counter and display until I can get it sorted! It seems to be one thing after another at the moment, I must have been very wicked!!

    I found a rather odd post on YouTube which might be worth trying....you briefly start the engine. turn off and remove the key, then you take out fuses No 1, 43 and 45, then put the key in and turn to position 2 for 5 seconds. Turn off and remove the key. Replace the fuses. Now when you turn on the ignition, the display and gauges are back working again! I have yet to try this, as it has been rather wet here, but I will give it a go, although I really cant see what that could possibly do to make it operate again!!

    Mind you I am at a complete loss to understand why it went off in the first place, as they wouldn't have touched anything electrical, changing a CV joint boot, replacing a suspension arm, and carrying out a wheel alignment would they?

    I did quickly look at the fusebox - what an appalling place to site it......it clearly wont be easy taking the fuses out, as there is not much room to work in. Why do manufacturers have to put important items like fuses in such inaccessible places?? I mean what is wrong with under the bonnet, so you can see what you are doing??

    Has anyone come across this "fix" that I have described? Frankly, whilst I will give it a go, I don't hold out that much hope of it working!!

    I had exactly the same symptoms on my 2003 E39, which presumably has the same electronics. I lost speedo and rev counter along with mileage readout, but I also had one rear window going down on its own, it turned out to be the battery on its way out. Battery replaced and all was well again

    Thanks Kleynie, I have had a couple of E39's, and both of them needed new batteries!! However, neither of them lost anything on the display! On my X5 the battery seems perfectly OK, and isn't that old in fact, it was replaced just before I bought the car 2 years ago. I haven't lost the speedo or the temperature gauge, just the fuel gauge and the LED strip along the bottom, and no issues with windows either. I will give my local BM specialist a call shortly, to see if they can come up with anything, unfortunately they don't work on Saturdays - lazy whatsits!!

    The car was in the garage this morning...….the news is that the instrument panel is U/S, they are talking of about £1100 to supply code and fit a new one!! I enquired about fitting a S/H one instead, which they said could be done but that there might be a problem if the mileage on the S/H one was different, especially if it was lower mileage, as it can flag up a message saying the mileage has been tampered with! They also mentioned that there were some stored faults, relating to the EGR valve, the ABS system and the transfer box, which would show up on a new panel when it was fitted. Just what I needed to hear, as potentially that little lot could be VERY expensive. I guess the EGR valve could just need a clean, which I could have a bash at, but the other two are rather more worrying.

    My son is calling round tomorrow, so I will try and get him to try the fuse "fix" first to see if I can resurrect the old dash that way - as I have nothing to lose that way. Spookily, when I was driving over to the garage earlier, the fuel gauge started working again, and the fuel consumption gauge too, but by the time I got to the garage, the fuel gauge had suddenly started reading full. After leaving the garage, the fuel gauge doesn't register at all, but the consumption gauge is still working, very strange.

    So my options seem to be, 1) try the fuses out, wait 5 secs and replace 2) Replace the instrument panel and pray or 3) Buy a gallon of fuel and a box of Swan Vestas!! I am beginning to wish I had never bought the damn thing now!

    Unbelievably, my son called round today, and we got chatting about my car problem, he suggested he had a look at the fuses, as he is a little slimmer and lithe than myself!! We ran through the sequence YouTube suggested - 1) Put the key in and start the engine, then turn off and remove the key. 2) remove fuses F1 F43 and F45. 3) Put the key in, turn to pos 2, for 5 seconds, turn off and remove the key. 4) refit the fuses. 5) Put the key in and turn to ignition. Result - dash back up and working again!!! Fuel gauge back, rev counter back, and LED display operating again!!

    I am over the moon about that, I never expected it to work, but now it has - brilliant!! I am no electronics expert, but I just cant see how doing that sequence can sort out whatever the problem was. I can only assume that it is along the lines of computers, and a few other electronic gadgets, where you have to turn the power off for a period of time, and then it resets itself , and then all is well again.

    Get yourself the info into the hidden menus too, you can access them through certain number of pushes of the wee mileage clear' button.
    I printed out the procedure and bound it into a small book, referred to it quite a few times, before resorting to my code reader. :)

    Have you turned it off and on again.....?

    Good news for a relatively simple fix. Hope it stays that way.
