Hi Chris When you say the computer are you referring to the cars onboard self check system or a Diagnostic program plugged into the OBD port. A program such as ISTA will show all recorded faults and whether they are currently present or not Normal suspect is poor contact at the actual lamp holder a long time ago I brought a good electrical contact cleaner and some electrical contact paste. A good clean with contact cleaner a smear of contact paste normally fixes things. Early X5's suffered with rear light issues (water ingress) BMW's fix was change the whole unit mine was as described plus a thin smear of silicone to seal the lamp unit. Dave

Or upgrade to a 3.0i engine basically the same block 255hp just make sure you get the ECU with the engine. If you get a copy of PA Soft BMW 1.4.0 you can register it to the chassis and the other units Dave

Morning Simon Good find with the coupling fingers crossed the Eibach springs give the look you want. Remember once fitted get a 4 wheel alignment done it will save tyre wear in the long run. Check out the M-sport catalogue I am not aware of any body kits that have been developed but then I like it looking "Factory" my mods are under neath engine, brakes suspension. So I have 360 whp with brakes and steering to keep it in order, my wife's Outback has a full Perrin engine with 450 whp Dave

As your car is out of Warranty (unless you have an Extended Deal) talk to a BMW Specialist (there is a register of BMW Specialists just Google) they will (a) Be half the BMW cost (roughly) (b) will have all the tools and knowledge you need. There are also a plethora of Independent garages who are very capable of keeping your BMW on the road plus Fuel Saystem specialists out there. Also a heck of a lot of Trucks and Busses have refurbished injectors. BMW will have supply contracts with a small number of manufacturers a hiccup with one causes issues. The wider market doesn't have the same restrictions Dave

Hi Who on earth told you that 67k was about their life !! Just had a quick look at Euro Car Parts website here in the UK they are listing injectors for your engine from several suppliers Bosch Lucas etc so there doesn't seem to be a shortage here? As for mileage that they last, the injectors in my X5 (original) have covered 160k my Brother Inlaw runs 5 series touring and covers massive mileages on his 5th now all have covered 200+k he has only suffered 2 injector failures. You really are over thinking this Dave

Morning Chris It depends how you have diagnosed the intermittent problem ? By actually identifying the issue or by reading what others have suffered? Many Dealers will have a min charge/time for a diagnostic session, about 1/2 hr roughly. How ever the main workshop schedule will be sett for services etc so a diagnostic job will be slotted in as and when. If I were certain of the diagnosis I would fix it my self. However if your car is still under Warranty then pressure the Dealer to fix it and provide a loan car. Dave

Morning Dan When you scanned the car and got these faults a question or two? Do you have warnings up? Does the radio work? Does the Heating/Aircon work? My bet is they do. I would make sure the battery is fully charged and in good condition. Then connect your diagnostics, turn your ignition ON, "DO NOT START THE CAR" clear all faults. Ignition OFF. Then repeat do not start the car the current drop will cause all sorts of false fault codes due "low voltage" re-scan with a full battery. You may find you see a different result Good Luck

Morning Alexandra Welcome to the Forum Fuel injectors are rated by the volume of fuel they allow into the engine. So as long as your "replacement" injector is rated for your engine there is no reason that it shouldn't give goo service for a very long time. If you think about it from a different point of view if you had fitted a brand new injector you would be driving home with 1 new and 3 used ones !! and not worrying. If as you say the car is running fine then you will probably be still driving it this time next year, Go For It Dave

Yup they had the Lola's, GT 40's, Astons running wild Saturday Afternoon

G'day Les Welcome to the Forum Nice looking Car Bluetooth in this age of Beemer was not one of BMW's finest efforts I am afraid. The ULF modules are often available if it is that,or possibly the Bluetooth antenna it's self. Worth checking if the units memory is full there is a way of clearing the memory check your handbook as I think 4 phones registered is it's max. There are a few sound system upgrades check out Dynavin or Xtrons. Exhaust systems just research your local market and suppliers would be my advice as we are in the UK our recomendations probably won't help much. ENJOY your Beemer Dave

Morning Bga Welcome to the Forum Something like Osram Nightbreaker bulbs may help or you could try LED replacements, our son did this on his Toyota Pickup they work well. Or you could source some HID headlamp units second hand Dave

Brilliant, met a lot of really "OLD" friends, I think I need a chiropractor after trying to jitterbug we both should know better at our age but sometimes ego overcomes common sense 🤣 High light for me was the Classic Touring car race really my era. Dave

Morning Jim I have actually had a BMW Dealer Service Manager try to tell me running a "Diagnostic Programme that was not "BMW Licenced" could damage my car" and BMW would be within their rights to cancel Warranty and refuse assistance !! 😁 Guess he never needed my custom anyway 🤣 I remember when onboard diagnostics began in the late 80's early 90's to many Manufacturers and Dealers/Specialists saw it as an opportunity to keep total control of their product. They also saw an opportunity to convince many car owners that under the bonnet there is a "box of Bats" and if you touch it yourself they will escape and your car will never go again 🤣 That education program has been so successful that there are thousands out there who don't know the bonnet actually opens and seem to think it's Dealer only access 🤣😂 It Grates with some of them that they are not the only one with a key to the "Bat Box" forgetting sometimes that they have a "Business" to run that survives on "Customers" and "Good Will" he will need you long before you need him. Remember the Fault Warning can often be a symptom not the cause so if you are showing an injector fault check the injector loom,plugs connectors and earth points as well as the injector its self. With the Bro Inlaw's car it was definitely running rough no clever diagnostics needed. Dave

Sorry we were intending to be there but got kind of side tracked at the Revival Hope everyone enjoyed themselves Dave

Hi Simon Welcome to the Forum The only dumb question is the one you don't ask, terrific motor by the way. Several ways of lowering depends on your budget, (1) lowering springs check the Internet (2) Adjustable spring/shock set (3) Butcher approach cut the springs (1) OK but it is what it is once done if your not happy the only way to change is more springs? (2) Adjustable spring/shock set would allow you to get the stance you want Would be my route (3) Repaired 2 cars that have been butchered so NO just NO M sport wheel check the internet I have read of folks doing this from Memory you will need the slip ring and a loom extension. Not sure on the coding My brother Inlaw has run a few of these in Touring flavour he has had them ECU tuned and in practical terms like my X5 (manual and sport) once the initial rush has passed manual selection is rarely used they have so much grunt that if you tread on it's tail it just Goes ENJOY Dave Kenny will be along he is rapidly becoming the world authority on the 535d 😂

Hi Dan Is the car running the correct oil ? Is the oil level correct ? If yes is the answer to both questions it could be a sticking pressure relief valve in the pump there is another in the oil filter cap or a dodgy oil pressure sensor. The fact it seems related to motorway driving and then slowing down sounds like low oil level. I would first flush the engine to clean any crud from the system refill to the correct level with the correct oil plus new filter and oil filter housing cap. Changing the pressure relief valve in the pump is a sump off job so fingers crossed not that one. Dave

Morning jss33 Welcome to the Forum These are pretty tough engines so unusual damage Take a look at www.realoem.com it's a BMW online parts list put the last 7 digits of your Vin into the search box it will call up your model. Then in the engine section open the Cylinder Head section double click the part number and it will bring up a list of alternate part numbers and the Models they were used in. These engines were used in several models from the E46 to the Z4 Good luck with the rebuild Dave

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
