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

Hi Paul I would guess the oil level sensor is on its way out the only PITA is you cant change it without draining the sump so Oil change time job. Dave

Morning Edward Welcome to the Forum I have to admit I am ignorant of the later 7 series cars but Westfailia were BMW's OEM choice as suppliers. So my starting point would be to find a Westfailia specialist and talk to them Hope this helps Dave

Morning Paul Welcome to the Forum First point of call check the fuse diagram and fuses if that doesn't fix it then a Diagnostic Scan is needed by a Dealer £££ an Independent a Specialist or someone with a BMW capable scan tool A quick look at ISTA WIS shows fuses 120 and 128 are phone related Hope this helps Dave

Morning Lissa Welcome to the Forum I guess the first step is getting an estimate of cost to repair, then measure that against cost of changing the car One of our sons (a tree surgeon) had his pick up written off by driver who claimed it was parked in a dangerous spot ?? Straight road two wheels on the grass verge and warning signs out as they were working as well, Police checked the guys phone records he was texting at the time ?? Hope you find away to get the car sorted Dave Sunny Sussex UK (and it is today 😊

Morning Stuart Welcome aboard Dave

Morning Mark Welcome to the Forum Your car has Disc's front and rear plus the master cylinder, I assume that the garage changed both the front calliper's and discs? Brakes don't apply themselves unless your car has Cruise Control with distance control (which I don't believe 1 series had). That leaves the Rear callipers or Master cylinder, if the binding happens a hand near the wheel centre will let you feel the heat (don't touch the wheel or hub unless you don't mind loosing skin 😁) If all brakes are binding or even just the Front I would suspect the Master cylinder remember it is separate to the Vacuum Servo Good Luck Dave

Morning Tino My copy of INPA/ISTA worked straight out of the box (lucky me) it runs on a Win7 laptop that I already had Merc Star, Volvo, Toyota/Subaru, and a couple of other Diagnostic progs on. However one of our sons friend has a 1 series road car and a 1 series Drift car he was always here or borrowing !! Finally he has brought his own 😁 his copy runs on Win10 laptop we downloaded a Virtual Machine loaded Win 7 then followed all the directions but it took 3 attempts to load the Drivers. With his copy he has 2 Com leads one Yellow Ethernet that is for ISTA a Silver USB lead that has the 3 position switch that one is for INPA and is where we had problems with Drivers I have mailed James he has put a request to the Techies in Germany fingers crossed they get an answer. His first thought is a Can bus issue as he says normally they work unless something physical is broken (a wire or pins) Dave P.S. I only use the Ethernet cable with mine as ISTA seems fine being backwards compatible

Morning Tino INPA/ISTA should recognise Chassis and ECU data and harvest it automatically, well mine does. I get Chassis information, Engine and any history recorded Just sitting with a Coffee studying the wiring diagrams up to 2007 and 2007 shows a resistor symbol in connector X13376 at Pin 1 Green/brown trace 2007-2009 shows no resistor symbol anywhere X13376 connector appears to be part of the vehicle access system it links to the DME Pin 2 Black/green trace that is part of the Start system Later today I will try and talk to an ex neighbour who is now a senior guy in BMW see if he can find any more help Dave
