Ha Ha Ha that doesn't look OEM!!! I have a German Pointer dog that can solder better than that 😆 When you did the Vin check what seats were spec'ed at Build.? Take care if connecting/re-connecting as some have an airbag in the shoulder of the seat. You should be able to find wiring diagrams in ISTA/INPA that will help find what he was "Modding" this time Dave

You really did find a super star with the guy who owned your car seems his mantra was "if in doubt cut it out" what a nutter. Is the connector there or did he cut the wires !! If you want to reinstate it talk to someone like Quarry Motors and ask if they can supply a climate unit with the connectors. That way it's a solder job cable for cable. Dave

Morning Kenny First your persistent Faults, 4 Faults from where you started pretty damn good I say well done Mate. AUC sensor normally mounted on the top side of the fan housing I have tried cleaning the filter and even changing the filter material in the sensor it's part of the HVAC. They go wonky on a regular basis but don't seem to have much effect on how the HVAC works (well not on the X5 anyway) it is only my "if it's there it should work" attitude that keeps me changing it. If replacing make sure you have the correct part number. Rear Stratification controller (why can;t BMW just say Rear Climate Control ?? Is it turned on in the iDrive learned that from Bro inlaws cars, There should be a control panel under a cover bottom of the console that lets you select settings (a mini HVAC) set it to auto) Also after all the things you have discovered is it connected ?? Fogging Sensor Under the cover behind the rear view mirror measures humidity to prevent screen misting. They either work or don't normally they come with a tool to help fitting. PDC, Passenger side Centre Rear sensor needs the connector cleaned and checked if it still doesn't work change the sensor. I keep a cople of sensors as they seem to hate Jet Wash or Car Wash on the X5 and contra rear right is a regular culprit. Now INPA/ISTA when using it, First make sure you have a fully charged battery, turn the ignition on DON'T START the engine. Carry out scan clear any faults. Turn Off Ignition. PA Soft BMW 1.4.0 doesn't seem to mind if the engine is running or not Almost done Kenny Dave

Afternoon Giles Welcome to the Forum I daresay the Crank Case Ventilation system will be sooted up, check all the Vacuum lines and replace if clogged. The last thing would be Coil Packs A diagnostic session with INPA?ISTA would tell you much more. Dave

Hi Antony Looks like a storage device, is thea slot for it anywhere on the iDrive ?? In the armrest maybe? Dave

Often fault codes are misread many folks don't realise that they often are a symptom not the cause, plus as they disrupt communication on the Bus system they throw other spurious codes. Proud of you Dan you have come a long way in a short time. Dave

Morning Jim My brother inlaw had 2 failed injectors on one of his previous 5 series from memory his BMW Dealer quoted around £300 per injector plus diagnostic plus Labour fortunately he had an extended Warranty. However his car had covered over 200k at the time. He has had several 5 series all with the same basic 3.0d engine but in different versions 530d x 2, 535d x 2, all have run well over 200k, his current 540d (same engine type just more turbo's). Only one has suffered injector failure. He runs injector cleaner every 4/5 fill up just to help. So I would guess at todays prices a BMW dealer would ask close to £500 per injector Plus fitting 😲 So are you suffering issues or is this a precaution? A Diesel specialist would be worth finding and talking to as refurbished injectors can save quite a bit in cost. Even perhaps a secondhand set from a low mileage car, there are several BMW specialist Dismantlers out there who are very knowledgeable and reliable I have used Quarry Motors several times over the years. Dave

Morning Ros Welcome to the Forum Take a look at www.realoem.com either put the last 7 digits of your Vin in the search box or work by selecting model year etc then search the relevant section. You will get part numbers and small exploded drawings showing what should be there. Dave

Thanks for the update Dan Dave

Top man Dan We now have another member with hard won knowledge Now you can enjoy your BMW Dave

Hi Reedie Sorry bit late replying, it depends on how worn your other tyres are? This affects all AWD vehicle's the rolling radius of the tyres front and rear must be within the manufacturers tolerance or transmission wind up can occur which can damage the transfer case or a diff. Providing the replacement tyre is (a) same size make/tread pattern and your existing tyres are around half worn you should be OK. Dave

Hi Stephen Try www.satnavupgrades.co.uk I have heard/read they are very knowledgeable but have never used them. Dave

Afternoon Vince Welcome to the Forum I have read several posts on other Forums of people changing the screen for a 10"+ screen that is inclusive of the Android/Carplay software apparently this connects and integrates with your iDrive. My brother inlaw runs 5 series Touring he has had several but as yet hasn't tried this so I have no direct experience. As for Supermarket fuel one of our sons is a Chemical engineer he works for Shell, he tells me that the Supermarkets buy on the Spot Market and often are buying the same fuel as Shell, BP, etc etc so in practical terms there should be no difference. For what it's worth I have run my X5 on Tesco fuel for years as they are always several pence per litre cheaper and as the old saying goes "So Far So Good" Dave

Going back a few years when I was in business we were upgrading the Baggage System at T4 Heathrow. Prior to contract one of the BAA engineering team announced that Noise for the system would have to have a noise level of 60DB measured 1m from the drive unit. At midday (a quiet time for airports) ambient noise in the terminal was 89 DB outside the terminal with the M25 1mile away we measured 96 DB, we tried at 3am with everything shut down except the terminal air handling we measured 54 DB. I asked the BAA team were they measuring ambient noise + or did they seriously expect a piece of mechanical equipment to generate 6 DB? The real issue was until that point they had no Base Line, worse at that time Heathrow had 4 Terminals due to age and construction every building gave different readings even turning off fluorescent lights changed levels. Yet as we stood in the terminal at 3am to the human ear it was Cathedral like. My point is when in our car it isn't just noise but vibration that we hear/feel, our ears would hardly notice 3 or 4 DB (well mine won't to many years listening to Pink Floyd 😂) I hope Graham can find a solution but I fear unless he get's used to it it won't be with his X1 Dave

Morning Graham As you will be well aware the suspension and bushes also contribute heavily to NVH transmission. So if your car is on 17" tyres already you and your suspension isn't Sport? you will have the softest settings. Sound proofing I am not aware of any kits for your (doesn't mean they are not out there) Measuring so clinically you will need a base line, do BMW actually release a base line? Also road surface type and ambient noise will effect outcomes. As for tyres they can make a huge difference my X5 4.6is runs 275x40x20 Front and 315x35x20 rear so lots of contact opportunity for noise the last few sets were Michelin the current set are Yokohama. My X5 is 18 years old so I am used to it, but when my wife notices then the difference in road noise is marked with the Yoko's. I don't and never have actually measured NVH in my cars but these tyres have made a reduction I am not suggesting you change to them as your suspension set up is different just my observation. I rarely use the radio as I like the sound of my V8 which can be heard even at Motorway speed over tyre noise. Good Luck with your hunt Dave

Morning Larry Welcome to the Forum I take it the new thermostat is correct and working OK ? If you are not finding puddles under the car then check the carpets inside (hope there aren't any internal leaks. Hopefully there are no wet carpets, then I would check the areas that can swallow water and boils it off. So simple things first is the expansion tank cap sealing properly, the turbo runs Fliping Hot and any coolant leak around the turbo will be boiled off but it should leave traces, white residue so check all the hose connections carefully. The one you don't want to think about is head gasket but a sniff test by a garage will tell you if there is any exhaust trace in the expansion tank, fingers crossed there aren't any. Good Luck Dave

Morning Jim Contact your supplier for a 5 m extension then before installing add a 5m Video cable a 5m Male to Female SMB cable and a 5m radio antenna extension plus a Fakra to ISO converter. The SMB lead will connect from your existing Nav antenna to your head unit and the Radio antenna using the Fakra converter will connect where the existing radio and its Quadloc connecter are the video lead i obviously for the camera. To install I ran mine along the passenger side following the route of the existing main loom under the back seat under the plastic edge trim at the doors. Unbolt the front seat I didn't unplug anything just tipped the seat back which gives access to the carpet join under the seat run the loom across under the join to the centre console. Take off the plastic side trim on the console and run the loom I use a curtain wire to feed pull cables through tight bits. With the loom in place connect the Xtron and make sure stuff works, if all good work backwards refitting trim seat etcetera. JOB DONE Panoramic Roof sadly not one of BMW's best efforts this, a BMW Main Dealer will want to fit a complete new roof cassette £££££ there is a host of information on the net plus some excellent videos on fixes or if your lucky just a reset. My 4.4 had a sticky roof but due to (a) Aircon/Climate control it wasn't used and (b) just when I was going to fix it a Rudy Great tree fell on it and squashed the car. When looking for a replacement I found my 4.6 without a sunroof 🤣so not an issue. Enjoy tinkering with your Beemer Dave

Hi Graham Welcome to the Forum OK give us a clue just where is this "Smooth Road" 😂 most of ours are like ploughed fields with white lines?? What wheel tyre combination are you running ? remember Runflat Tyres have a reputation for harsh ride characteristics. If I recall the X1 runs 18" with 225x50 tyres an alternative may be 17" with 225x55 tyres non runflat would give a better sidewall compliance Dave

Afternoon Jim You only need the 5 m extension if your original set up had the screen up front all the rest CD Changer Nav Bluetooth unit are in the left rear cubby in the boot. The BM54 radio unit and TV are under the floor with the battery If your original set up was Business Radio up front then you wont need the extension as the connecting Quad Lock is behind the dash. The best place for the Extension if you need it would be from Extron then you know it will fit Dave

Morning Mauri Did they disconnect the battery ? Can't think why but possible? Have you checked the obvious fuses etc I have seen a fuse not blown that needed removing and putting back before working? Your Radio also has a 10a fuse under the Quadlock connector on the radio unit in the boot. Hope this is some help Dave

What car does your friend have? can he wind his car lock to lock with one finger? what is his experience? is he an qualified mechanic? or is it something he has read or seen on TV? There was a Wheeler Dealer program where they where winding a big old Yank Tank steering lock to lock with one finger, the cars wheels however were not on the floor it was on the ramp. Are your tyre pressure's correct ? If they are then I would say what you have is as BMW designed it. when on the move it should feel positive giving good road feel. If you want very light power steering perhaps a BMW isn't for you, try a Subaru Outback as I have indicated in your other post Dave

Morning Steve As long as the Power Steering fluid is at the right level and there are no leaks it should be OK. To drain and refill can be a messy job. When you hold your power steering against the end stops (full lock) you are hearing the pressure release vales working, quite natural. Winding the car's steering lock to lock while stationary is not good practice as it puts unnecessary strain on all components. When you say heavy steering what are you comparing it too? As an example compared to my wife's Subaru Outback the X5 feels as though it has no power steering 🤣 but when you consider that the X5 is almost twice as heavy and tyre width is half again?? While on the move in either car there is no real difference. Dave

Morning Jim Hope you are fully recovered now. With the Xtrons install, if your OEM install had the Nav screen up front you will need a 5m extension which will run from the BM54 Quad Lock connector to the front of the car (this gives all the speaker and power connections) When I fitted the Dynavin in the 4.4 I added a 5 m extension with SMA connectors for the Nav and a 5 m radio antenna extension along with a 5 m video lead for the reverse camera. With your PDC sensors all rear sensors can be accessed from behind the bumper check the connectors first (get a good contact cleaner and some contact paste I got mine from RS Components) Front PDC sensors Centre are accessible but the corner ones are a bumper off job I am afraid. Not sure about the OBD scanner tool ( if it is Bluetooth you may find it can't communicate with the cars Ibus system) I remember reading issues others had with Carly for BMW when trying to use it with I bus equipped cars. Have fun Dave

Hi Abu Welcome to the Forum A BMW Dealer will have an hourly rate close to £200 (someone has to pay for the free coffee) plus Oils, Filters and Fluids Try a search of the Register of BMW Specialists there should be one nears you who will (a) have all the right kit to provide a good full service and register it on your iDrive. (b) They will also have up to date Diagnostics but hourly rate will be probably less than £100 per hour, no offense to Halfords Kwik Fit or Mr Clutch but I wouldn't let them loose on my BMW I have watched Kwik Fit boys slamming wheel nuts up with a windy gun and then put a torque wrench on the wheel nut!!! Yep it clicked, it would it's vastly over tightened. Hope this helps Good luck Dave

We will be there if we can Trevor long time since we went to a Car show instead of Horses 😁
