Hi James You really should get a copy of BMW 1.4.0 ($20) load it onto a laptop then you would be able to run your own Diagnostic Scan. The idea is you don't need a BMW Dealer to have dealer level diagnostics and the cost is far less than changing parts, it would give you accurate information on where to look If you can hear the fuel pump running is there pressure at the fuel rail? If not there could be a blockage in your long list of stuff changed has the vacuum line to the fuel filter been checked? The Pins are the pins in the electrical connector/plugs a pinout will tell you which pin is connected to which colour wire so you can the test end to end continuity. Clearly if there is a break in a wire or poor connection the problem may be that simple Dave

Morning Giovanni Welcome to the Forum Your transmission is made by ZF it is for the protection of the transmission ZF advise service at between 60k and 100k (depending on environment and use) or 5 years. Having owned 4 BMW X5's all with ZF transmissions 5 speed, 6 speed and like yours 8 speed. My thoughts are why cut corners when the gearbox is likely to have only one or two services in the time I own it and genuine ZF Fluid and Filters will set you back around £250/£300 the same applies for the Transfer Box and Diffs. I have seen alternate Fluid kits available that may save around £100 but as a rebuild is anything from £2000 up personally I wouldn't risk it. Having said that I do know someone who used a Luiquid Moly Fluid kit in his Jaguar (same Box) and so far so good Hope this helps Dave

Morning Frank As I said they don't normally break, that's why there are so many for sale second user. I still have an Instinct/Doubt it is your issue, if your compressor runs but isn't lifting the car properly that is where I would start. Again get the part number this time you won't find any second user just refurbished or New I hope it fixes things be great if it did let us know Dave

Hi James If you aren't aware take a look at www.realoem.com put the last 7 digits of your Vin into the search box it will call up your model then look at Lights section. You should be able to see what you need and get an idea of how it goes together. If you need parts you will have the Part numbers then just Google them to get the best price It was the rear unit I wondered if the indicator was a Bulb (it is on the E70) Dave

Morning James Welcome to the Forum First I gave never had a chance to poke around a 2 series so some information may be needed If the rear lights are LED they can still fail (had it on my E70) sadly they are not serviceable so the whole unit will need replacing, or (fingers crossed) is there a Bulb that has failed? A failed bulb often causes rapid flashing of other indicators on that side. I would first do the easy thing and check if there is a bulb to change If it isn't one of the easy fixes then a Diagnostic scan is needed if you have program access do you have diagnostic access? Hope this helps Dave

Morning James Welcome to the Forum If you can get a Diagnostic Scan done using a BMW capable system it will help a lot and probably save changing parts that don't need changing. For your model I believe has I-bus so software like BMW 1.4.0 is available and really cheap (about $20) its easy to use and will actually give you Dealer level diagnostics and programming (if needed) Just load it onto a lap top and it will as said allow so much information and test ability. However as you get an attempt to start, the place I would begin is check/test the Fuel Pump relay and it's loom back to the ECU. See if you can download a Pinout for the ECU to check which pins need checking testing Hope this helps Dave

Morning Sreejith Welcome to the Forum How many miles are on the clock ? What is the general Condition ? These are indicators of where to begin looking. I would start with a Diagnostic scan to understand if there are any underlying control issues, what fault codes are stored? Next both the Inlet and exhaust side need close inspection If you changed the Boost hose did you change both (one from the turbo the other to the inlet manifold) is the Inter cooler in good condition? Is the EGR valve clean and operating condition ? Is the Boost control sensor OK (Diagnostic should tell) Is the Turbo working correctly ? On the Inlet side no leaks all vacuum lines attached and in good condition? Hope this helps Dave

Hi Richard Welcome to the Forum With normally aspirated engines an ECU tune will not give huge power gains from what I have read your 2.5i will be around 180/190hp stock a good ECU tune should see 215/220hp First google ECU tuners in your area and talk to a few see what they think outside that it is conventional tuning Headwork, injectors, Throttle body, exhaust, inlet etc a friend of one of our sons built a 1 series Drift car 2.5i based had around 350hp when he finished I guess it's the Carol Shelby question, Speed cost money young man how fast can you afford to go 🤣 Enjoy your Beemer Dave

Morning Phil First thought "is it a genuine wide body or an aftermarket kit that's been fitted" I would check one of the Vin Decoder websites using the Vin number to see what the original build sheet tells you. As it may be a rare customer special order One of our Z car owners may have more thoughts Dave

Morning Frank BMW do like to charge stupid prices🤣 in the UK you can buy a new one with warranty for around £150. 5 minutes to change a used one from £20 to £50 and as said I have not seen a failed one since 2001 (my first X5) Just remember BMW do not make these parts they buy them in. BMW Air suspension is a fairly simple system 2 Fuses a Relay a Control Module a Compressor 2 Ride Height sensors and 2 Air Springs The most common faults are leaks ? Leaking Air Bags. The next is Compressor failure the leak causes the compressor to run far to long and it wears out and can't produce enough pressure to lift a heavy car. Your car is 12 years old so the suspension at an age where it could do with a refresh whether its springs or air. You need to know what the problem is. Is it Suspension going down and not inflating ? Is it compressor not running ? Is the suspension lopsided ? A Scan with BMW capable software would tell you/us more My X5 is 2009 vintage I have just fitted a new compressor as the original was getting tired (over running) £140, with 5 year warranty. Both air Springs £160 with 10 year warranty whole job took me 5 hours on a Saturday morning I don't have a lift so all work was carried out in my home garage. If you cant do the work yourself you will need the help of a mechanic having software that is BMW capable is the only requirement otherwise your guessing Dave

Let me have a wild guess 🤣🤣 Dave

Hi Stephen Have you tried the BMW Specialist Recyclers like Quarry Motors ? Or Google the Register of BMW Dismantlers and try a few Dave

Morning Frank How are you so sure the car needs a suspension module? Not saying they can't fail but in a long time I haven't seen one that has. Just take a look at www.realoem.com put the last 7 digits of your Vin into the search box it will bring up your model then search rear axel for the part you want or take out the one you have and take the part number from there. Once you have the part number Google for the best price and supply. Your choices are Second User or New Dave

Morning Gary Welcome to the Forum At 17k I would suspect that the Bushes are OK but check that the Upper Control Arms are torqued correctly The supplying garage should take care of that with no argument even if it means new upper arms, as these are faults that were are present at sale. Even if it is outside their 60day warranty the sale of goods act is on your side as clearly the car in its current condition isn't suitable for purpose Push Good Luck Dave

You have a "list of jobs" too 🤣 I tried confusing her by starting at the bottom I thought if she saw ticks near the bottom 😅 Top tip it didn't work 🤣
