Morning Tovi Welcome to the Forum I believe Oil is 0-30 Fully Synthetic Coolant sounds right check www.pelicanparts.com they should have all the information you need. Great car ENJOY Dave

Morning Trevor I am 3 years ahead of you age wise Is there a reason you are changing just the rears? Tyres : Different tyre manufacturers while construction is similar tread and final finish will vary the finished size, so if you were to take tyres of the same size from 2 different manufacturers make a chalk mark on the floor and the bottom of 1 tyre then roll it forward 1 revolution and mark the floor, then repeat there is a high chance that the distance will differ in some cases significantly. So say the difference in distance covered by 1 is 25mm greater, doesn't sound much but in a mile that tyre will make 7 or 8 fewer revolutions which if it is across an axel may be absorbed by the Diff. But if front wheels are not travelling the same distance as the rear then there can be damage caused to the transfer case and diffs. So BMW (and all AWD manufacturers) take great care in selection of tyres and manufacturers to ensure front rear rolling radius's are consistent. BMW also advise changing sets (not always practical) but normally all 4 wear at a similar rate unless alignment is out or of course there has been damage to a tyre. OEM supply for your car was either Dunlop SP Sport 01 or Pirelli Rosso Asimm Currently BMW approved tyres include Michelin Latitude, Bridgestone, Yokohama. Pirelli Cinturato. (my X5 runs 20" Staggered and currently on Yokohama tyres) So try to stick to the same manufacturer (ie: Pirelli) as you will have a better chance of maintaining the rolling radius. After they are fitted reverse on full lock slowly if there is jerking and snatching while reversing it indicates a potential problem with wind up in the transmission. Dave PSL I do most of my own car maintenance as well as family and friends always been a "hobby" the only concession to age is things take a bit more planning and sometimes take longer (more tea, coffee and beer breaks) Plus I rope in my sons (younger and bendier) for certain jobs. I do use a BMW Specialist for annual service and on the odd occasion when I either don't have time or (rarely) the inclination

Morning Trevor Welcome to the Forum From the tyre size you quote I take it that your tyres are same size front and rear? Cars with a staggered set up (Wider rear tyres) generally are more susceptible to transmission damage due to mismatched rolling radius in the tyres front to rear or across axels. The important thing is that front to rear rolling radius isn't significantly different, I would think that the Pirelli replacement for the the Rosso's would be fine if going to another manufacturer I would take greater care. Dave

Morning Sam Welcome to the Forum I believe that there are 3 fuses that control interior lights. Check your handbook on my Brother inlaws 535 Touring they are 28,42,54 You will need to check what yours are (handbook again) can you not call up your handbook in the iDrive? Dave

Hi Roger Obviously difficult to diagnose blind but throwing parts at the problem is an expensive way to fix it. When you put the key in the ignition and turn it do the dash lights come on? If they do try putting the car in Neutral and starting (could be the inhibitor on the gearshift) It could be the Power Relay or the Starter Relay. Have all main power fuses been checked? Under the bonnet(Hood) you should have a couple of charging point connections can you measure power there? To be sure you need a diagnostic scan by someone with a BMW capable diagnostic program. A good website for you is wwwpelicanparts.com they have an excellent reputation a great help section and How Too's with pictures. Hope this helps Dave

Morning Roger Welcome to the Forum Great choice of car by the way, are you a DIY home mechanic or do you rely on a Garage for help? Dave

Morning Dennis Welcome aboard Dave

Morning Mags Welcome to the Forum I take it you have BMW's Evo system? Your BMW dealer is really saying is "it's something I know nothing about and can't be bothered to find out" sadly you will find folks like this in all manufacturer Dealerships no matter what the make. The truth is the first conversions are by third party companies and from what I have read are very good and not difficult to fit. From what I have read there are 2 types of system (1) Replaces the existing NBT/EVO system and requires Chassis registration. I have read that getting the bluetooth working can be a faff but not difficult. (2) Is an add in box that integrates with the onboard system and requires no coding. System 1 has Navigation bult in system 2 allows Google maps or your phones nav to be used I am passing on what I have read on some technical forums and have not practically experienced either system, however when BMW introduced their first iBus system (late 90's) there were many "cant be done" comments from dealers. Fortunately the world is full of inquisitive engineers who had hacked the iBus system and made it possible to fit 3rd party upgrades before system was a year old. As time went on they got better and better and easier to fit. Same with the NBT/EVO system. So look outside the BMW Dealer Network, Google what your looking for and find what you want talk to the supplier before purchase to ensure you are getting what you want then go for it. Dave

Morning Graham Does your service history show any battery change? As the label indicates it is a BMW fitted part, by the part numbers it may be the original so it could well be 14 years old 😲 The Voltage readings seem to show a battery in reasonable condition though at 14 starting current could be giving it a beating. Before jumping in and changing the battery check the engine earth strap and all connections at the starter motor. Magnetti starter motors did have a reputation for pulling huge current as they age so if can get access to a clamp ammeter measure the draw at start. I have seen reports of 800+amps. Dave

Morning Mike Welcome to the Forum Some information on Engine and mileage would assist? You say the car was overheating? Obvious thought is head gasket, did the garage carry out a pressure test and sniff test in the Header Bottle? You say you cam smell the antifreeze that to me suggests it is either dripping on the exhaust or if your model is turbo charged a hot turbo. Dave

Morning Patryk Welcome to the Forum The battery was disconnected (Earth connection) when you were carrying out the work? When you recharged the Battery you did charge it from the charging points under the bonnet ? If the battery was not disconnected and you charged it at the battery you could have caused issue's with several units due to a surge in current. If the battery is (a) OK (get it checked) (b) Make sure it is fully charged, by either charging OFF the car or from the charging points under the bonnet. Check there isn't a voltage drain. Then disconnect the battery (Neg first) and leave for 1/2 and hour while disconnected re-check the battery voltage (12.8v or close) anything below 12v indicates a dying battery. If all good re-connect the battery this should reset any units that were Off Line if not the a diagnostic scan is required. Dave

Hi Kenny Sorry been out shooting (1st day of the Pheasant season) Yes looks that way If you find the part you want and double click the part number you normally get a list of other applications/models just like the one above Dave

Welcome to the Forum Paul First thought is the thermostat correct and working ? Next you have changed the water pump, is it fitted correctly is it's rotation correct? How much coolant went in? (should be between 8.5 and 10 ltrs) Was the heater set to max and engine running cap off to bleed any air out of the system? Lastly the fan sensor and wiring need checking (I believe the sensor is in the bottom hose) Dave

Morning Kenny The gearbox has its built in Mechatronic control unit which receives signals from the EGS controller. The EGS gets information from the DDE on engine RPM Throttle Position etc plus other units ABS ASC Normally the DDE, EGS EWS and LCM are all fitted at build and rarely changed. When you scan it the EGS will/should give any fault information on some models even condition of Trans Fluid. Both the EGS and Mechatronic unit can have their programs updated, The ZF specialist local to me did mine several years back while servicing the box. Dave

Hi Daniel Welcome to the Forum From memory there are 2 earth straps the main one is on the right engine mount to the chassis. I haven't done this on a Diesel but it should be in the same place you may have to remove the splash guards to get at it. There is also a secondary strap on the exhaust towards the back of the car. Hope this helps Dave

Morning Brendon Welcome I am not sure but I think the I drive versions of Navigation only show the selected POI on the map in use, once you turn off it resets. One of the other's with more up to date Nav systems than mine (still steam driven) will be along to help. Dave

That is all good news then Kenny 😁 all back together by Lunch time 😂 Soon you will be driving the automotive equivalent of George Washington's axe it's had 47 Handles 7 Heads but still the "Original" axe 🤣🤣 A real top man Kenny you will end up with a superb machine Dave

Morning Kenny ZF Part is the same but check the loom connections just in case BMW have done something sneaky at the connectors. If you are not changing the Gearbox Control unit all should be good with no coding issues. As the box is out are you changing the Torque converter ? If yes, I would make sure the torque converter is rated for the 535 as it has a significant torque increase to handle. I would also check with ZF or a ZF Agent to see if any software upgrades are available for the box. I had this some years ago with a box change on a Volvo T6 V70 with a box from a Volvo T6 S80. I just swapped the box loom for the one on the original box, my Volvo Agent said "Cant be Done" but strangely was happy to upgrade the software 😁 Good Luck Dave

Hmmmn Good Old BMW Dealer A quick look at realoem tells me that the Roll bar for you car is also used on the F45LCI F46 F48 and Mini Clubman F54 while the M235 roll bar was used on F39 F40 F44 and two Mini's the Clubman F54 and Countryman F60 Mind my BMW Dealer told me that "someone" had fitted "Non""standard parts to my X5 that could make it unsafe to drive !!! The non standard parts are Poly bushes I asked him if they were unsafe why were BMW use them on their BTCC cars ? No answer not mentioned again. Dave

Morning Brian Normally the Vin Decoder will give a list of codes (left column below) that identify the equipment to be fitted as (a) Standard and (b) Customer order S806A BMW Third Brake Light SZP1A BMW Performance brake system SZP2A BMW Performance air-induction system SZP3A BMW Performance muffler system SZP4A BMW Performance shift travel reduction SZP5A BMW Performance suspension In realoem is there a different roll bar Part No for the M version ? My wife's Subaru Outback is heavily modified, Olin adjustable suspension all round 356mm 6 pot front brakes and a 3.0 Perrin engine ride is on the hard side. My X5 4.6is is all BMW OEM and the ride is OK on good roads Harsh on most roads Dave

There seems to be 3 posts here all relating to the same Issue/Car Simple answer is as you recently purchased the car it is the Dealers responsibility under the sale of goods act to supply a car that is fit for purpose. Take it back to the Dealer Dave

Hi Samantha Welcome to the Forum My X5 is fitted with reverse camera and PDC system and my daughter told me "Dad they are a waste of money there is always a thud when your to close" Sadly that isn't a joke bless her. So your problem, the BMW PDC system is fussy but great when it works. You may need the help of a willing assistant depending on how hands on you are but no special tools are needed. On your model all sensors can be got to without removing stuff the fact you don't get a Beep when selecting reverse may need some digging though? do you get warning bongs/beeps if you leave a door open or lights on? If yes that's good news. Next with the use of your willing assistant remove the boot floor spare wheel cover and spare wheel, then udo the 2 nuts and 2 bolts holding the suspension compressor down and carefully prop it up at the back of the back seat. You will now be looking at the battery, BM54 radio, TV unit (on the right if fitted) look down nearest the back of the car you should see a control unit with 3 plugs on the top Blue White and Black. Question does your car have a tow bar? If it does you should have an extra control unit alongside the main PDC controller this disconnects the rear sensors when the trailer plug is inserted. So sensors front and rear are the same. The simple thing would be a diagnostic scan which would identify which if any components were duff. If not I would have the trusty assistant check that everything was clean (get some electrical contact cleaner RS Components are a good source) plug and unplug the connectors several times using the cleaner. The fact you have no sound could point to the actual controller (assuming you have the other beeps) All parts are available on the well known Auction site at sensible cost Take a look at www.realoem.com it is a BMW parts list put the last 7 digits of your vin number into the search box and it will bring up your model the search for the bits you need. There are small drawing to help plus if buying you will have the correct part numbers and know they will fit. Hope my ramble is a help not confusing Dave

Hi Brian Welcome to the Forum That's a new one 😂 a soft BMW Two things I would do (1) check BMW Vin Decoder (Google) it will bring up your cars build sheet so you will have the original setup (2) check www.realoem.com (it is a BMW online parts list) put the last 7 digits of your Vin into the search box it will bring up your model so you can check what parts are available. Certainly M sport springs and dampers are normally stiffer. Hope you find what you need Dave

Hi Mark Welcome to the Forum Asking folks to diagnose a noise without hearing it is just about impossible. I also don't follow the Specialists advice, from what I have read the newer engines have 4 Lambda Sensors where earlier engines have 2, but their job is the same to measure the Nitrogen Oxide (Nox). They are mounted before the Catalyser and after the catalyser so that they can measure the difference and signal the DME to adjust fuel/valve timing accordingly. I think you have 2 catalysers so 4 sensors.A diagnostic scan should show any issues. The advice given seems to be inline with Diesel's to force a regeneration of the DPF (Diesel Particulate filter) If the knock is only on cold start? I would first check oil levels as low oil will let oil drain back to the sump which then would give several components the opportunity to rattle/knock on start up, once the engine has run and oil pressure is in the system no rattle/knock. If oil level is OK I would check for something loose in the exhaust that once warm expands and stops the rattle. Hope this helps Dave
