    Auto box too keen to change gear?

    Reset the adaptations either using INPA or just disconnect the battery overnight. Occasionally my 530i transmission used to change gear at odd times and the reset always used to cure it It's a free thing to try and at least will eliminate it One thing that can confuse things is the MAF, does cruise control work ? It might seem odd but a faulty or disconnected MAF sensor can cause odd things to happen inclusing stopping the CC working. Other than the above if you have INPA always a good idea to look for any fault codes as many systems are interconnected

    Don't buy an EIS radiator

    Years ago I heard exactly the same thing so paid more for a Hella unit (also from ECP) So it seems EIS was shit then and still shit...so avoid. Along with suspension components buying cheap is never a good idea

    Houston we have a (CCV) problem

    I can't see how the brake fluid has anything to do with it. The servo doesn't create vacuum, it just uses the inlet manifold vacuum I'd firstly do the usual test of seeing whether there's a vacuum at the oil filler cap when idling, if there is then that points to a CCV issue. If not then it could be other things and whether a sharp stop is related I don't know, however this would obviously cause the sump oil to slosh around a bit - if it splashes a large amount of oil up one of the cylinders and that cylinders rings are worn that might explain it. It might be worth checking the state of the spark plugs to see if all even, possibly that might point to something. You can disconnect the pipe from the CCV to the dipstick fairly easily I think, if oil pours out of it then clearly a dipstick issue needs to be investigated. It's easy to remove the dipstick without having to remove much else as I did it on my old 530i to replace the o-ring Of course it could also be the valve stem seals - but I'd suggest trying to rule out as much as possible first with these tests Good luck

    Suspension

    Old 15 year old car Wants to spend as little money as possible What could possibly go wrong ? Either do it properly or not at all. You will just end up with a chavved up car with a horrible ride otherwise

    Reassurance needed! Massive oil top up

    CCV failure can cause high oil consumption on the 530i so I'd check that - even if OK if the dipstick tube drain is blocked that can cause problems. Id also use 5W30 or 5W40 rather than 0W40 with a high mileage engine

    Misfire mystery

    Rather than replace coils I'd move them instead, ie swap coils 3 and 4 with 1 and 2 Then you can check the fault and see if it moves Next step swap spark plugs around and see if fault moves That's the easy bit Then if 3 and 4 still a problem you could check compression (easy to do if you're removing the spark plugs) which should identify any mechanical issues then you can try swapping injectors I'm not familiar with the V8s but could any vacuum lines or blanking plugs in the manifold be faulty, if they're at the back where cylinder 3 and 4 are maybe that's a possibility It's a process of elimination really which 99% will isolate the fault unless it's a very obscure fault Good luck

    how to top up the automatic gearbox oil?

    I'm sure BMW (or ZF) specify it for a reason

    E39 530i mysterious coolant loss

    My 530i always used a small amount of water despite new radiator, hoses etc and never found the cause I'd get a pressure test done (or you can probably rig one up using a foot pump) - unfortunately the conclusion I came to was any leak was only when hot and the coolant would evaporate making diagnosis more difficult

    M54B30 running issues

    Idle control valve wont cause rough running or high emissions

    how to top up the automatic gearbox oil?

    Do not do this unless you have INPA or similar connected up. The oil must be topped off when the transmission is at a particular temp, 50C from memory

    Wet CCV hoses

    Check that the oil filter housing gasket isnt leaking, the fan will blow oil back towards the CCV Common issue on M54 and not expensive to buy the gasket

    E39, when to call it a day?

    Always difficult to make a call I enjoyed working on my old 530i when I had time and wasnt under pressure but at 170k miles there was a long list of things to do including a torque converter on the way out which would have meant it was not practical or economic to carry on. Although I would have loved to keep it and gradually do it up I had no space or time really, ultimately the car was still my daily driver so had to be reliable. My 530i was silver, SE spec with no options and high mileage so would never have been worth much. I traded in for a 4 year old 3 series which despite being nowhere near as well built as an E39 is reliable and has been minimal trouble. But new cars whilst more reliable, economical, faster etc have, I believe, much more potential to go expensively wrong. Lots of horror stories of things like timing chains failing which is virtually unheard of in E39 era cars If you want a nice car it's going to cost you, that's the inescapable conclusion I've come to A 1.0 Kia Picanto would do all I need and be very cheap to run but where's the fun in that ?

    2nd Crank Sensor failure in 6 Months...

    This is exactly what happened to my 530i At least with the O-Ring / spring clip design they're easy to change

    Tools for doing work

    I have a set of the Halfords Pro ratchet ring spanners. Very well made and always useful

    [E39] aux fan always spinning

    If it's an old pre-facelift car the aux fan speed was controlled by resistors and a simple switch. The facelift models (M54) used a coolant sensor and a PCM signal from the DDE to control fan speed in 1% increments I'd connect INPA up and check for faults and certainly on the newer cars you can use INPA to control the fan speed so this would be a useful test. INPA will also display the coolant temperature
