Hi Andy It surely isn't helping that's for certain BMW use a lot of Earth switched circuits I have traced quite a few Faults that were caused by poor earthing. In your original post you say 11 lighting faults did you find them by diagnostics or do you have lighting staying on? Or off ? Or flickering? I would replace the Earth straps clear down the faults the re-scan Dave

Hi Paul Yes the EGR cooler hoses and sometimes the cooler it's self, on the top of the DPF you should have an exhaust pressure sensor if it is acting up it can give all sorts of strange symptoms. There are a few good Videos online showing cleaning methods that should help. If you aren't aware you can check on www.realoem.com what is there and where stuff fits the small exploded drawing can be really helpful in knowing where bits go Dave

Hi Brian Welcome to the Forum Do you know if the gearbox has been serviced/fluid changed, the poor old gearbox is one of the often abused parts of the drive train. if it is low on fluid or has never been serviced that is where the problem may be The ZF schedule is service every 30000km or 24 months Hope this helps Dave

Morning Paul Welcome to the Forum You are on the money the EGR would be my starting point check all the hoses as well often they are clogged and get missed. Also worth checking the inlet manifold I have seen them full of soot Test the exhaust sensors as well I did the clean on a friend of our son's 120d we spent most of a Saturday cleaning everything they took it for a test drive on the bypass and they came back howling with laughter, apparently when he floored it on the bypass there was a huge black cloud left behind they said it looked like a special effect from a Harry Potter film 🤣 Good Luck with the Clean Dave

Morning John Have you looked at www.realoem.com it should let you see where the fixings are and what they are for your model Dave

Morning Darren Welcome to the Forum As I understand it BMW restrict the Hybrid versions to 750kg braked to protect the hybrid drive train. Petrol/Diesel versions are rated at 1700kg current models, earlier models 2000kg Confusing and quite impractical for many caravaners, me I will stick with my E70 as we tow a Horse trailer with two fat horses 😁 Dave

Morning John There should be 4 M10 bolts holding the seat rails to the floor ? So if you have only taken 3 out no wonder you are having trouble 😆 Will the seat height adjustment not give enough lift? Dave

Morning Andy I upgraded the FRM in my X5 4.6is which added a few possible functions Realoem only shows FRM 3 as fitted listed below are the part numbers and alternatives.

Morning Nick Welcome to the Forum If all you want is noise it will help if you want an increase in performance then there are a lot of other things involved. Manufacturers spend a lot of money on Fluid dynamics and gas flow analysis to get the best combination of power, performance and sound. The diameter of the exhaust if the silencer is replaced with a straight pipe will only flow the same amount of exhaust gas so apart from noise no change. A good ECU tuner will be able to find significant power increase particularly when combined with induction and exhaust modifications so it depends what your trying to achieve and how much budget you have Dave

Morning Andy Welcome to the Forum A diagnostic would be the place to start as it could be the footwell control module or Junction Box control module. Before changing the Footwell Module make sure it is the same part number a be aware that this unit also stores a record of the cars mileage so changing it will give a tamper dot beside the mileage on the dash display. So a replacement will need registering to your chassis and recorded mileage entered. Some BMW specialists suck their teeth and make it sound difficult and Dealers ££££££ You just need the help of someone with a good BMW capable diagnostic scanner ISTA/Inpa is best but Autologic Foxwell and several others can do it these days. Good Luck Dave

Morning Iain Welcome to the Forum Simple job swapping the stop/start button should take max 5 minutes. Prize out the existing button using a trim removal tool or a small flat screw driver with some insulation tape stuck on the blade to avoid scratches to surrounding trim. lift the button out and release the plug at the rear plug in the replacement and push it home. Job done Good Luck Dave

Morning Richard Must be the season for it I did exactly the same thing pulled the X off my X5 boot I used a number plate mounting sticky pad that I had in the garage, cleaned the badge cleaned the boot then trimmed the sticky pad to fit That was just over a month ago and 3 wash/polish sessions extra care now around the badges though Dave

Morning Alan Welcome to the Forum I have done this job (or similar seat jammed) on a 5 series. The only way I could figure out was to raise the seat angle at the front the motor that controls front rear movement was on the transmission tunnel side of the seat. The two bolts that hold the motor to the frame can be undone and the motor wriggled back to disengage the drive gear, the seat was then free to move so it could be taken out. Getting under the seat to release the motor was a real faff and high on the cuss list. Don't forget as soon as the seat is raised as high as you can get disconnect the battery to avoid any airbag issues. It goes without saying the job is easy peasy with the seat out. If you aren't aware use www.realoem.com to get the correct part number for replacement, if you have any issues let us know. Dave

Hi David Don't ignore 5, 6, 7 series models of around your cars age they all had ACC as an option as I recall Dave

Morning Simon Welcome to the Forum That is a very open ended question BMW themselves fitted everything from a 3 cylinder 1.5l to their mighty 3l straight six engines I guess the main questions are (1) what are you trying to achieve (2) how much work can you take on (3) how deep are your pockets The simple answer is to either refurbish the engine you have or fit a direct replacement that way you minimise the amount of work that would have to be done. Of course it also reduces the damage to your wallet Good Luck Dave

Hi Tim That price tag sounds like a BMW dealer hourly rate If the DPF is completely blocked back pressure in the exhaust could have stopped the engine rotating and caused the chain to jump I have read of it but never seen it in real life. If I recall the camshaft timing chain sprocket is slotted so if the cams are timed so the cam locking tool can be inserted it may be possible to slacken of the chain sprocket bolts and recover the timing. Then refurbished Turbo and and DPF I would be tempted to try that route but as your garage have quoted £6.5k I guess they wouldn't try. I have seen several Refurbished/fitted engines for around the £2k mark there are also BMW specialist breakers who may be able to help with a low mileage replacement I think I would be doing a bit more investigation into the alternatives and their cost before making hard decisions it is your hard earned after all Dave

Hi David Welcome to the Forum How frustrating can they not adapt a sensor from a newer model they must still be able to get them as they still sell ACC systems?? You can check www.realoem.com if you are not aware put the last 7 digits of your Vin into the search box it will bring up your model then check the Distance systems section. If you double click the part number it will give any alternate part numbers that can be used and the models they were used in. Not sure who makes the sensor if you can find out the manufacturers may help. There is a register of BMW Dismantlers I have used Quarry Motors several times for hard to source parts with great success Finally there are companies such as ECU Testing and Cartronix who have been able to bring stuff back to life for me in the past. Good Luck with the Hunt I hope this is of use Dave

Morning Tim Not good ! That is quite a list who diagnosed it ? Clearly the most important is Timing Chain how was this diagnosed, this is the biggest item due to the amount of labour This needs to be measured against cost of a replacement engine/car value DPF can be replaced or cleaned off the car the Turbo likewise can be replaced or serviced I remember reading that in the USA I think there was a Class Action that forced BMW to extend engine warranties worth checking and writing to BMW Customer Services Good Luck Dave

Morning Richard Not so long ago BMW were telling people the Gearbox was "Sealed for Life" this actually meant it didn't need servicing in the first 3 years while they had Warranty responsibility. The manufacturers of most BMW transmissions fitted to rear drive and Xdrive cars are ZF who recommend service/fluid change at either 60k or time dependent due to Transmission Fluid degradation. It seems they now include it in the cars inbuilt service schedule just like Brake Fluid and Coolant change cycles BMW cars with Front Wheel Drive the transmissions are I believe manufactured by Aisin Warner If you are DIY capable Kits to change Fluid and filters are readily available (make sure you use genuine ZF Fluid) If you are reliant on Garage support it doesn't need a BMW Dealer a good Transmission specialist Independent Garage or BMW Specialist can carry out the work Good Luck Dave

Morning Asim Welcome to the Forum Good fun BMW's I have seen two types on 1 series engines 1. A sealed unit BMW called it a "Heat Management Module" mounts above the water pump front of the engine. Just make sure you use the correct coolant when swapping them. 2. Similar unit same location but the Thermostat could be changed again correct coolant is important Your engine should be B38 to check the Thermostat location 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 the Engine section. The small exploded drawings will help with location and correct Part Numbers Good Luck Dave

Afternoon Jeff Welcome to the Forum Take care when changing wheels/tyres 225x45x18 were in fact a Factory option for your car so should be fine are they BMW wheels(tip If buying a set complete with tyres make sure wear rates are even) Be aware that 18" and 19" wheels were also offered as a Factory option in staggered sets (wider rears) tyre sizes then became Front 225x45x18/19 Rear 255x40x18/19 If choosing a staggered set allow for new tyres would be my advice to avoid issues As for your bearing noise does it increase with engine speed or remain constant ? I would check the rear prop shaft centre bearing Enjoy your Beemer Dave

Morning Alistair Welcome to the Forum Check your handbook and settings in the iDrive/infotainment system, check the media for any videos that may help with settings If all else fails try your dealer as your car is under Warranty if it isn't something you have done they should fix it Good Luck Dave

If they are a UK registered business you could try the Small Claims Court check out Money Claims on Line I had to resort to using them a few times when in Business straight forward and simple to use with a fixed fee structure don't forget to add interest to what they owe. If they ignore it they end up with a CCJ against the business and you could apply for a Bailiff to be appointed Dave

Hi Julie Welcome to the Forum You seem to have posted in the wrong place X5 Section not the 6 series section so lucky I saw this First thing I would try is a Re-set open the roof fully and then disconnect the battery Neg Lead for at least 15 mins (this is a Dealer trick) If that doesn't clear it then it is likely to be a sensor or possibly the mechanism If you guys don't have DIY skills to fix it try Googling The Register of BMW Specialists there will be one near you, They are normally ex-BMW trained Technicians and should have all the equipment and skills to diagnose and fix the problem Normally they are around half the cost of a BMW Dealer sorry as I am in Sussex I have no recommendations as I have never used any of them. Good Luck Dave
