  1. That's perfect if it's cold and the battery is flat.
  2. All good points above, I've personally seen 15V when it's cold (and that's how it's supposed to be). The alternator regulator is about £50 to £60 for an OEM part. You must disconnect the battery when replacing because the live lead is a permanent live almost direct to the battery. I'm not familiar with the 520d but the 535d regulator change is a 10 min job. From memory three nuts on the back of the alternator and lift off, no need to remove the alternator.
  3. How do you know it's the TC not other friction plates? I think the limiting factor on the pre LCi gearboxes is the oil pump that provides the pressure for the TC lockup. It was improved on the update of the 6HP26 that took it 700Nm.

    Torque converter queries

    The EGR glitch needs DIS or ISTA. I can't remember exactly but you can adjust how much the EGR activates. I think something like - 40 is the maximum correction and this fixes the problem.

    Torque converter queries

    You can get an issue where if you hold the car at an exact speed, I think between 70 and 80, you get a regular small "misfire". The car sort of misses a beat then carries on and it repeats I think every few seconds. The actual cause of this issue is the EGR. Apparently it's because the EGR is worn and you can calibrate it out using BMW diagnostic software - that's what they used to do when the cars were under warranty.

    DPF. Never re-gen'd?

    If you have a pre-LCi E61, in my experience both those numbers are a bit iffy. Firstly they are in metres (which is pointless) and I think I've seen them wrap round to read negative numbers on my car (the number of bits used to store the value in the car is too low). I've not even bothered looking in ISTA, I gave up with DIS.

    Tackling a blocked DPF.. (520d)

    Yes drop the whole exhaust off. It's surprising easy but it is heavy. Impossible without. I've tried both removing the exhaust and trying to remove the DPF without...

    I only really know about 6 cylinder BMWs but in those there was a separate DPF before 2007 but the LCi models have a combined DPF and Cat. The first half of the unit is the cat and the second half the DPF. You can still wash it out.

    help help problem

    I can think of three main suspects: 1. Failed regen attempts. If the EGR wasn't mapped out properly who knows what is happening. Multiple failed regens definitely cause your oil level to rise. Need to monitor the car with some diagnostics to see if it is trying to regen, when the last regen was etc. 2. Leaking injectors - need to get them tested. 3. There was something a long time ago when these cars were a year or two old....I think it may have been a fuel pump issue but I can't remember. It did cause a very rapid rise in oil level and usually was dealt with under warranty.

    Forced regens (keep resetting the code when driving) can clear it. A motorway drive for an hour should do a passive regen which may do it too.

    Which E61 bike carrier?

    I'd avoid putting bikes in the caravan.. They move around a lot because the caravan has little or no suspension.

    Poor beam pattern

    If the lenses are milky you'd be amazed how much that reduces the light coming out.

    First job is to sort the thermostat. You can view the temperature via the hidden menu (accessible via the mileage trip reset button, search on youtube). With the thermostat fixed force a couple of regens and you might be fine. If not then drop the DPF and pressure wash it out (the holes in the DPF are blind so you can only wash it out one way).

    Which E61 bike carrier?

    I would hesitate to hang a mountain bike + rack off a few small hooks hanging on to the boot. If you have a towbar I'd get one that fits to that (but unfortunately if you use it when towing you need to factor in the effect on nose weight).

    Compression loss on 1 cylinder

    Did you car have swirl flaps? If so that's probably the cause, one has failed and been ingested. If you do take the head off you need to get the correct head gasket for your specific engine, it'll be 1, 2 or 3 holes (marked on the old gasket).
