Afternoon Gerry Welcome to the Forum I hope you enjoy your Beemer Takea look at www.realoem.com it is a BMW online parts list which should begood for your car/year. Put the last 7 digits of your Vin into the search box and it will call up your model. Then search the sections you need to to get any Part numbers for spares that way you know it will fit. Oil, most main brands that meet BMW LL04 SAE 5-30 Oil Filter, Mann are OEM suppliers I use ECP for most bits but always search the nett for deals to keep costs sensible, don't dismiss the Dealer though they can be competitive quite often. For Warranty, BMW Warranty isnt cheap but check them out before making final decisions My 2003 X5 4.6is was full BMW history but as the warranty had lapsed by just over a year they declined I went with Warranty Direct who took it on happily and covered it until it was 16years old (a lot less than BMW) My E70 is with Warranty Wise best price when I brought it Good Luck and most of all ENJOY Dave

Wow lucky boy that could have had some serious consequences !! Do the Lottery quick 😁 Great pics and information Paul as BMW tend to stick to patterns with layout I think I will check the E70 tomorrow Dave

Morning Men Looking at the diagram I would say hood up boot lid open and the are in the Hood starage area. Not much help I am afraid as I have never had to explore this issue I would be more concerned about where it is getting in than letting it out I had a convertable in the 60's it leaked and was draughty a short ownership, same with Sunroofs when they became the big thing in the 70's. Only a few of my cars have had sunroofs since the 80's/90's and none of my X5's have had/hve holes in the roof. If I want the wind in my hair I stand on the Beach 🤣 Dave

👍🤣👍 A job well done

Yay we are back well done the Mods Dave

Hi Tony Unfortunately the only way to be certain is to take the Unit out and test with a multi meter from the Diagnostic print the module had registered a short circuit. The other intermittent communication faults I would suspect are linked to the short circuit some may need reseting once the module is changed Dave

Hi Tony That looks right to me, if you double click the part number in realoem it will bring up a list of any alternatives that may help Dave

Hi Tony Welcome to the Forum Looking at the Diagnostic it would seem so Take a look at www.realoem.com if you are not already aware put the last 7 digits of your Vin into the search box it will bring up your model. Then check the Lights Section you should find the part number you need there Try and find where moisture is getting to avoid more shorts. Dave

Hi Sue If diesel has reached the ECU then gathering as much evidence as you can (Google) from as many sources as you can to prove it isn't the unusual situation Dealers often pretend it is. Then try a letter to BMW UK asking for a solution with a copy to Rogue Traders. BMW didn't enjoy their last experience on the show and actually started helping customers I hope you can find a sensible resolution Dave

Morning Sue Welcome to the Forum Oh Dear First over the years there have been other similar instances (BMW don't make Sensors they buy them in) Temperature sensors leaching coolant which by cappiliary action allowed coolant to reach ECU plugs and now Fuel pressure sensors. BMW Dealers never fix/repair anything just Replace them normally at the customers cost ££££ I have read of many who have changed the faulty sensors cleaned the loom and allowed it to dry out with outstanding success. So my advice if you can't DIY find a more realistic Mechanic or Garage either Independent or BMW Specialist clean things down and change the sensor rest things and see how it goes Dave

Morning Sammie Welcome to the Forum Timing Chain (BMW recommend betweeb 80 and 120k) is an engine out job so clutch and rear main seal at the same time I would guess between £1000 and £1500 depending on who does the work Hope this helps Dave

Morning Charlie Welcome to the Forum Bit of a concern that a BMW specialist needed BMW to help ? Some thoughts, can the PCV valve be cleaned ? Has the specialist checked the system hoses for any damage ? Try checking www.realoem.com yourself put the last 7 Digits of your Vin into the search box it should call up your model, then search the sections for what you need there are small exploded drawings that may assist If I recall your car does have an Emmissions Control system and EGR valve with it's assocciated pipework and gaskets worth checking as I was always told Fault Codes can often be symtoms not causes Hope this helps Dave

The only recommendation I would make is only buy the best quality you can afford. You have the sizes stick with recognised brands. Many cheap tyres have earned the reputation as "Ditch Finders" remember they are the only thing between you going where you point the the car and stopping when yo need to. The last tyre change on my X5 I brought Hankook Ventus got a really good deal at the time with Just Tyres, but use the search engines for the best deals not just the cheapest tyres Dave

Morning Carlos Welcome to the Forum I have to say all my AMG Mercedes had Heated, Cooled, Massage seats and I only ever used tha Heaters on very cold mornings 🤣 Have you asked the BMW Dealer what tests they did and how they measured that the seats were working correctly ? Not just that the switch worked Dave

Morning Paul Great progress matey, as I said I have seen several MAF sensor looms damaged most the damage is close to the MAF end as many "mechanics" use the loom to pull it out (even in a Dealers). All have been repairable with a soldering Iron and shrink wrap. BMW actually do a number of repair looms worth checking if there are any available. Certainly check the EGR and its loom Dave

Morning Paul Never used that system but it is giving you much clearer information. 3FF0 is the MAF 40E9 is the EGR not opening or closing correctly The MAF (Mass Airflow Sensor) measurs volume of air The MAP sensor (Manifold Absolute Pressure) is normally on the inlet manifold (sometimes called Charge Air Sensor) realoem should help with location Check Google for test parameters and methods, remember fault codes are not always the cause but a symptom so test the plugs and wiring looms as well. I have seen a few MAF plugs with damaged wiring over the years where heavy handed folks have used the wiring to pull out the plug Dave

Morning Zeet Those are invoices that itemise what they are billing and the cost of items changed. Your F15 is a complicated beast with any where between 65/70 up to 100 different Control units, many have to communicate with each other and control sensors for the smooth running of the car The Drivetrain has specific control units, the ECU (Engine Control Unit) TCM (Transmission Contol Module) TCM (Transfer Case Module) DCM (Differential Control Module) Each of these modules has a number of sensors that it controls and all communicate with each other and other units in the car. As your car had a Drivetrain Issue I would expect to see a Diagnostic report that showed ECU and a message either No Faults Found or a list of Fault codes and explanations followed by the same for each module (In the screen shot modules in Green are OK Yellow there is an issue. Each Module can be interrogated to identify faults. This would show only the elactronic controls are OK or Not and which sensor or component may need changing. A Diagnostic Scan will not show Mechanical Faults these require a whole different series of tests I would be asking what tests were carried out and evidence of results that led to the diagnosis of a new engine required You have paid a lot of money I would expect to be able to see what they have done I hope this helps and doesn't confuse Dave

Hi You can check with a multi meter at the sensor plug first find the power feed I use a pin to probe for voltage to earth. With the meter connected you should see the the voltage change as exhuast back pressure builds if not change the sensor. Similar test for the MAP sensor normally voltage fluctuates between 0 and 5v as prssure changes. Check You Tube there are some good Videos there Changed both on an N47 2.0d for a friend of our son last year from memory they were about £15 each from a local Auto Factor The fact you were getting Blue Grey smoke would make me look at the MAP sensor as that effects Fueling Good Luck Dave

Morning Paul First the Glow Plug issue should only become a problem below -5C or inhibit Regen if the engine can't generate enough internal heat 40E9: exhaust gas recirculation control, position control 4B81: Exhaust gas recirculation rate control, control deviation This is where the detective work begins there still could be an issue with the DPF sensor even though you have changed the pipe also check the Map sensor. Check realoem for the location of any pipes steel or Flexible and make sure they are clear Good Luck Dave

Morning Zeet Wek Welcome to the Forum I take it that a full Diagnostic scan was carried out? Do you have a copy if not ask for it. I would want to know how they came to the decision what evidence was it based on? If internal damage was suspected the internals can be inspected using an Endoscope to confirm just what is going on it can even store pictures The reason is your Dealer seems to have concentrated on the petrol engine yet the car is a Hybrid, so the Battery pack, Charging, Motor and all the controls and sensors that allow it to work with the petrol engine are oart of the Drivetran It doesn't end there, the Gearbox Transfer box and axles along with last but not least the tyres are all Drivetrain and effect other components As an enthusiastic Home Mechanic who has always maintained his own cars, I have the equipment and use it surley a Main Dealer should have it? I would expect them to have a Duty of Care to their customers to not only diagnose the issue but demonstrate the diagnosis Dave

Well as they say "Every day is a School Day" apparently you do have additional NiCad batteries I just spoke with an old friend in the US (he was a neighbour for years works for BMW now very senior in the US) The SI Board is part of the instrument cluster so you have to remove the cluster then remove the SI board which has 2 NiCad battery's soldered to it. He says that BMW never try and change them as they break down and leak causing a real mess his advice is get a new SI board it will be quicker and cleaner and is what BMW workshops do However there are a couple of Companies in the UK ECU Testing (Derby I think) and Cartronix (Chertsey) it may be worth giving them a contact to see if they can help Good Luck Dave

Hi Christopher I just tried to trace your Vin number with no luck I entered (or tried to) it into www.realoem.com which if you are not aware is a complete BMW Parts list the same as is used by BMW Dealers so would show all parts and part numbers I have carried out a quick manual search (if the Vin is accepted it automatically calls that model up) I searched E28 and E34 models and could find no refference Does the Haynes manual not give a clue ? BMW UK may be able to help they have a Classic Division Sorry Dave

Hi Graham Welcome to the Forum You need a diagnostic scan to help find the cause, otherwise we are all just guessing Dave

Aaron Stop guessing and looking for quick fixes start checking and testing Injectors can make a little noise (very small rattle) unless they are loose or the seals have gone. An injector needs fuel at the right pressure to work correctly and atomise the fuel. Your back to finding the cause of the noise Dave

Morning Paul Good find with the DPF sensor just the servo sensor to go With the Glow Plugs as your in there change them all and the controller. They don't effect starting while ambient temperatures are as they are, they are important though as they are used to boost combustion temperatures during a Regeneration Phase. If you use the car on Motorways or Main Dual Carriageways probably less so, but if your driving is mainly short local journeys they become important Dave
