Little bit of a head scratcher for you Stu Try some injector cleaner (if you haven't already) I know it takes a tank to work it's way through but worth a go while your recovering. The next step is ignition and injectors Good Luck Bud Dave

Morning Tony Welcome to the Forum No I don't but I do have an Estoril Blue E53 X5 4.6is and an E70 X5 in Titan Silver Very nice ENJOY Dave

Hi Mark Welcome to the Forum Have the battery checked put volt meter across the chage points under the bonnet. Anything less than 12.5v will indicate a battery issue If the battery is good then you need a diagnostic scan to help with finding the issue Dave

Feel for you, I would put it in writing to BMW UK copy to BMW Munich state the sale of goods act and the fact the car is unsuitable for purpose and the time to correct or repair has become unreasonable. Give them a time for a solution to be reached just turn the screw Good Luck Dave

This sounds like the Dealer is the whipping boy between BMW and Yourself Maybe write to BMW UK telling them that they have destryed your faith in the structural integrity of the car and you want it replaced That may at least trigger some action Dave

Morning Norm He is quite right the key blade has a chip which is read by an induction coil in the key slot The battery only powers the radio link to the Access system to provide remote operation. I did read of a guy in the states who moved the blade to a new Fob then registered the fob to the car BMW will probably want £100 + for a new key Dave

Hi Norm Welcome to the Forum Sounds like a Tensioner needs replacing possibly water pump but the tensioners are the place I would start Dave

Morning Stu Ouch!! Fuel pressure check would be my starting place. From memory (old and dodgy) should be around 50psi any thing lower will give the symptoms your getting If I remember Pelican Parts did some great write ups on Fuel delivery and pressure plus stuff on injector testing worth a look at their site I have been told it only hurts when you laugh 🤣 Get well soon Matey Dave

Morning William Welcome to the Forum First the headlamp washers, I beleive your headlamp washers are the same system as the E70. Which means you have a fuse to control the Headlamp washer pump but the actual washers are extended by water pressure retracted by spring, if they fail it's quicker and easier to just change them (I learned the hard way) As for the Map I think the only way forward will be to talk to the original Map installer they may know what has happened. Never heard of a simple service disturbing the ECU map but they may have seen or heard of it before (I did read on a Subaru Forum that a Garage tried to copy the map but that ended with a fried ECU) Dave

Morning Not necessarily I recently had an injector fault that randomly shut the engine down no codes no EML The only way to find it was to actually run live data on the Diagnostic (INPA/ISTA) and drive the car when the fault occured I was able to record it. That was the only way to identify it Make sure you check for any air and vacuum leaks a small crack/split in a vacuum hose The inlet has several hoses that rely on "O" ring seals are they all good Dave

Hi OK 101k is no great mileage so I would start by checking for any Air or Vacuum leaks on the inlet side initially. I would also check carefully the injector loom for any damge or cracking to the insulation. Go on line and get the test procedure for Injector loom and Injectors (test for resistance) Have the engine mounts been checked ? Snapon is normally OK but it depends on the model some older ones revert to Generic codes Dave

Morning Ali If all connections are in place and tight is the IBS cable connection good ? Have you tried running live Data to see if you get any more information Dave

Morning Paul Welcome to the Forum The 8 speed ZF box is pretty tough my brother inlaws 540d is beyond 400bhp it was mapped almost from new and is around 200k with out issues, but it is very well maintained gearbox transfer case and diffs have had 3 oil/fluid changes. His has had a gearbox software update but that was part of the general gearbox service last time So for you to need a gearbox remap just what are you planning 🤣 Dave

Morning Spblade Welcome to the Forum A rough idle can be caused by a number of things from an Air leak to as you say an injector issue. Is it 116i or 116d makes a difference in diagnosis If the scan tool was a generic tool it will miss a lot you really need a BMW specific tool How many miles has it covered when was it last serviced (not just an oil change) Dave

Morning Paul Unfortunately BMW as did many other manufacturers started fitting plastic parts not just externally but also internally and with many heat cycles they become brittle as they age I have seen the the Header tank on a friends Mercedes his was just under the cap around the neck so only showed when the engine was really hot. When I rebuilt the 4.6 (plastic chain guides Failed) I found several coolant "O" rings in the coolant system were starting to weep. BMW wanted to sell complete hose assemblies but many of the parts I sourced were from the USA (Dinan) new Cams,Throttle body gasket sets amonst them were a set of Viton Coolant system "O" rings worth checking those as well. Good Find Dave
