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

Hi Ken Wow lucky man 😁 As the car has been stored and Aircon systems loose a little each year anyway my first thought would be try getting it serviced (Kwik fit have summer deals) The machines used vacuum out and check for leaks if it wont hold a vacuum the machine wont try and re=gas the system. My local BMW Specialist has a mobile guy come in (£65 for my E70) Good hunting for a specialist Dave

Morning Jim Just be aware that if an MOT Garage suspect a DPF delete it's an automatic fail plus it's logged so going elsewhere wont work Better solution is just give it a good run once a month in my opinion then no risk of MOT fail Dave
