Well that was fun first ISTA wouldn't acknowledge the EHC (Electronic Height Controller) took it out cleaned the pins back in now I could see it but it wouldn't allow Calibration ?? So go at it from a different angle inflate airbags individually. All of a sudden back to normal, ride height recalibrated 🤣 Hope thats the end of the story Dave

Morning Paul Welcome to the Forum I have no Hybrid experience other than riding in one 😁 Like Manufacturer quoted MPG for Petrol and Diesel models most figures are laboratory maximums (probably with all accessories shut down) and real world driving shows them up. After 3 or 4 years I would expect battery efficiency to have fallen off a little and from what I read most testers have found around 40miles to be a real world optimum. Dave

Morning Jerry All straight forward stuff, even easier if you have access to a lift. If not the get the car as high as possible and well supported on axel stands. Gearbox I use ZF parts and Longlife fluid last service parts Fluid Filter gaskets etc cost £250 as a kit (Tip make sure you can undo the filler plug first) If your car has Dynamic Drive rear diff it will nave 3 compartments requiring 2 different oils 2 outer chambers use a Carbon Modified SAE 75 80 oil (i buy from BMW it comes in measured .5ltr bottles) the main Diff section uses a standard 75 90 (I use Liquid Moly) same tip make sure you can undo the filler plugs first I know two people who drained the diff and couldn't move the filler plug !! Front Diff Oil and Transfer case fluid I buy from BMW, the transfer case drain plug is a Faff to get to BMW drop the Transfer case support frame, I brought a stubby Hex drive set so I could get at it If you have INPA/ISTA there are Workshop directions and guides Good luck Dave

Hi Paul Welcome to the Forum You need a good Independent Garage but one with BMW capable diagnostics or a BMW Specialist who will have the kit and knowledge There is a Register of BMW Specialists which you could Google which should give you some local contacts Poor servicing is sadly quite common due to (a) many modern cars can have the service indicator reset without work (b) extended service intervals due to modern oils some up to 30k are just nuts. That means a car with 70k may only have had 2 services ?? The only real evidence is a good old stamped book and a wedge of receipts Hope this helps Dave

Morning Steve Welcome to the Forum I believe there are several Videos on the internet that deal with turning off Comfort Access/Keyless entry Hope this helps Dave

Well when the bag went boom it really did go BOOM Both sides changed sensors changed solenoid vale changed then the monsoon arrived 🤣 knew I should have done it in the garage Still just got to fire up ISTA tomorrow and register the new sensors and calibrate the suspension ride height

Morning Update 2 All Parts are here Solenoid Valve, Air Bags, and Ride Height sensors so 3 guess's what I will be doing today 😅 Dave

Morning Welcome to the Forum Are you wanting to upgrade all 4 callipers or just the fronts ? Is the reason for upgrade performance related or for show ? Upgrading Callipers, first check what brake disc sizes are standard on your car as you may need to consider Disc's and Callipers together. If replacing Discs and Callipers make sure you have clearance in the wheel to clear your new brakes so you may also need Wheels/Tyres you can check www.realoem.com for what original equipment is on your car and what was available for say M Sport or M series cars Dave

Morning, Update 1 Lots of digging both ride height sensors test out correctly compressor is fine the only thing in my digging testing head scratching and reading is the Solenoid Valve on the compressor. Although the solenoid valve tests OK my conclusion is one side has been sticking and not allowing the lowering/levelling function. Course of action now is 2 new air springs 2 new ride height sensors and a new solenoid valve block, once fitted inflated leak tested and calibrated things should be good again Dave

Morning Germaine Welcome to the Forum Your post raises more questions than advice I am afraid 1. How many miles has the car covered 2. What type of journeys short local less than 5 miles or Motorway 3. When was the car last serviced ? Then we may have some clues to help you Dave

Well I was feeling smug as the X has been running so well but it must have been talking to Stu's 😁 Wednesday the passenger rear suspension decided to inflate to the max 5" higher than the drivers side had to drive home but because the cassis is being twisted it begins to rapidly wear the inside edge of the passenger rear and the outside edge of the drivers front !! New tyres are booked anyway but could do without this. Get home OK next morning plug in and using ISTA look for issues a few I knew of (Glow plug controller and rear fog light) but no air suspension errors darn. Ride height sensors tested OK Compressor OK Control Unit OK ?? So into the diagnostic's program and calibrate and reset the ride height. Then an hour ago it did it again passenger side to the max but this time the airbag gave up and burst. Looks like I have a fun week ahead first find out why ? Then replace the airbags and reset everything again maybe change the ride height sensor as a precaution Update later Dave

Morning Peter Welcome to the Forum The only thought I have is you have an Analogue Dash (fixed Clocks) and you have seen cars with Digital Dash panels ? To go the BMW OEM route I think would be expensive to say the least £££ I have read of a company in the UK who have developed Digital Dash retrofit kits called Demonized UK. From what I have read they are very good though I have never seen one or used them may be worth a Google search Nice Motor by the way ENJOY Dave

Morning Michael Only one thing to say really ENJOY Dave

Hi John Welcome to the Forum The most common cause for the DTC/DSC warning is a failed ABS wheel sensor or a Fault with the ABS unit possibly a fault with the Steering angle sensor. A Diagnostic Scan with a BMW capable scanner would verify the issue, if it is a wheel sensor it is a straight forward change if an ABS unit there are several repair companies in the UK who repair them far cheaper than a new unit. Dave

Hi Eduan Welcome to the Forum First place to check is Sub Frame mounting Bushes, on a 19 year old car they will be tired. In Order to check rear suspension bushes the Air suspension has to be deflated not a difficult task but essential. Again I would expect a 19 year old car to have a lot of wear and is probably in need of a refresh. Tip if refreshing the suspension get new camber bolts for adjustment mark the old ones position with a bit of Tippex so it all goes back as original. If the suspension is good then drive shafts, diff, Propshaft are next for checking Dave

Morning Steve Welcome to the Forum Quick look at realoem shows both 155A and 185A alternators were used for your car Part Number 12317521178 is the 185A was OEM The 155A shows as a Remanufactured replacement alternative. Realoem also states that the Aluminium Screws are use once so will need replacing part number 12310392568 set of 4 shows Good Luck Dave

Morning Nigel Damn Bambi 😅 we just don't eat enough Venison in the UK 😅 Totally agree with you if it's on the car it should work and it bugs me if it doesn't. I brought my copy of BMW INPA/ISTA a long long time ago (can't remember where now) but a friend of our son brought a copy last year from www.djwwautodiagnostics.co.uk he paid £90 and it works really well (save him blocking my driveway while he uses mine 😅) The best software is BMW INPA/ISTA which will give you full Dealer level access to your car for diagnostics and repair information, it also contains Wiring diagrams and Workshop information Apparently the company are UK based and give full back up, though I personally have not used them but he is a happy bunny Hope this helps Dave

Morning Nigel Welcome to the Forum A diagnostic scan will confirm the issue so before spending your Hard Earned that would be my course of action. Either find a BMW specialist or a good independent garage that has BMW capable diagnostics (Foxwell, Autologic, iCarsoft) Or if you are a DIY fan then buy your own Google BMW Diagnostic Software for less than the cost of a single visit to a Dealer you could have your own. Dave

Morning Chris Welcome to the Forum That's a lot of water 😢 I fixed a 5 series for a friend of our son his was no where near that bad though. With the 5 series the rear door card had been removed at sometime and the vapour barrier was missing that added to the drains in the bottom of the door being blocked. The bottom of the door was just full of water. When it rained or he went through a car wash it overflowed and filled the footwell. I cleared the door drains a lot of water was held in there I dried it out with a heat gun (checked the roof drains as well they were OK) Fitted a new vapour barrier took out the carpet and sound deadening thick pad which was sopping, gave them a spin in the washing machine then dried in the sun. While they dried I jet washed the car to check for leaks (none found) so I replaced the Door Card sound deadening and carpet he has had no issue over the last 3 years. With luck that will be your problem 😁 If it isn't then you have a serious leak under the car or in a seam Hope this helps not hinders Dave

Morning Nellie and Paul As far as I was aware and have read the issue is with the ABS unit or to be accurate 2 ABS units (ATE MK100 and ATE MK 25A) that were fitted to quite a few models (not just BMW) between 2011 and 2020 and shows more often on cars with DSC. The big problem is the rate of failures compared to the number of cars with the unit fitted is small so BMW avoid recall on safety grounds, plus it seems (as far as I know) to only seems to happen outside warranty ie. over 3 years old leaving repair cost with the Owner. BMW will also argue that a car serviced by their Dealerships would pick up the fault at Brake Service and advise repair. Always expensive as BMW will replace units not repair them. BMW will also wash their hands if a repair or service is carried out by a Non Franchised Garage (But they are not alone here just about all Main Dealers and Manufacturers are the same) That doesn't mean all is lost there are a few Repair Specialists in the UK who repair (and improve) these units one I have used is ECU Testing who are very good. Now the calliper sticking? is the the ABS pump not releasing all pressure after braking or a fault with the calliper its self? it needs checking with a BMW capable Diagnostic system which would identify if it was a calliper failing/sticking or ABS issue. Also it is good engineering practice if a calliper sticks to either service both callipers or replace both If replacing Fluid only use BMW Spec fluid. It is sad to read tales of woe like this as generally the X1 is a good car and there is nothing wrong with Independent Garages other than some do not have the specialist knowledge or equipment If you are not able to DIY then I would find a BMW Specialist close by I am not a BMW garage just an enthusiastic car owner who loves to service and maintain my own cars plus some friends and families. Over the years I have amassed a strong collection of tools and knowledge including Diagnostics which allows me to work at Dealer level on several makes (Volvo, Mercedes, Audi, and BMW) Dave

Hi Andrew Do you have any Diagnostic software ? or know someone who does ? By selecting live data I can see my injectors and whether they are operating at the same (or close volumes) I can also so see fuel rail pressure. So I don't have to get my fingers dirty unless there's and issue. My brother In-law's 540d estate is at a little over 200k and running well so mileage shouldn't be an issue I would start by checking for any leaks on the Inlet side. Unmetered air will cause a misfire Dave

Morning Andrew Your description sounds like fuel delivery so worth checking fuel rail pressure and sensor as a starting point. Also an Injector check (don't know how many miles you have done Inlet side all Vacuum lines and pressure hoses good (no cracks) throttle body OK Fuel filter OK Dave

Morning Tino Nothing from James just mailed him as a prod I brought an X5 E70 cheap as a project the previous owner had spent a fortune changing parts and finally lost patience with the car. The fault list was huge but after a lot of digging I discovered BMW use earth switching so started working through all the multiple earth points that helped (Not much but it helped) Next while inspecting the loom in the boot I discovered cable splices/joints covered with a clear plastic sleeve (couple of pictures attached) when I moved one it just fell apart, turns out the joints are twisted and compressed then covered with the sleeve. If moisture gets in the joints corrode (black residue) and come apart. I am not sure when BMW started doing this so maybe worth checking yours. I spent an hour or so stripping these joins and soldering then sealing with shrink wrap. I was able to see all modules for the first time and clear down all fault codes and fault memory. That was 3 years back and almost 40k still need to keep an eye on it after all it's a BMW 😁 When my sons friend brought his copy we had to set up VM ware and a Virtual Machine running Win 7 on his Win 10 Laptop initially getting the Drivers to work was a pain at first we loaded and reloaded them several times before we could get it to run cleanly. For drivers you could try ESYS (that's where my copy came from) Also check whether you need 32bit drivers or 64bit Dave

The old "un plug it and restart" 🤣 Glad it was that simple dave

Hi Jim My experience with my own E70 3.0d which I brought very cheap as an MOT fail due to DPF being tampered with. Is the EGR had become clogged and that had caused the same situation as your in, the old owner removed the EGR and DPF then fitted a refurbished Turbo. The MOT fail drove him over the edge and he just wanted rid of the car. I got a used EGR and cooler plus a used DPF from Quarry Motors, had both professionally cleaned then fitted and a little faffing around reprogramming and I have a very cheap E70 3.0sd which has passed 3 MOT's now. For information I brought the E70 as a project and to keep the miles down on my E53 4.6is. Most of my journeys these days are less than 10 or 15 miles but once a week I give it a Motorway run of about 45mins and so far so good. As said if an MOT Station suspect the car has been tampered with it's a fail. As your DPF has been regenerating personally I would keep it Good luck Dave
