  1. Annual mileage is a bit down at the moment. My cars & bike: F11: My 525d had its MOT in October 2020, and it was another clean bill of health. Only 146,200 miles on it as of tonight, so 1200 miles since October, and 1000 of that was work. Boxster: I bought a 2000 Boxster 2.7 in 2018 for £3k. Looks like they're generally up to £5k now - Boxsters are finally on the turn. Not that I'm selling. 1200 miles in the last 3 years. Golf: We've owned a Golf GTE since March 2020, and done 3200 miles since then. Corsa: My Son's 2012 Corsa has done 1200 miles in the last 2 years. Suzuki GSXR 750: My bike. 40 miles in the last year. Oh dear.

    E61 2005 coding out EGR

    He knows his stuff, he has helped me in the past when others (allegedly more reputable) said I needed to buy a new ECU at over £2k. It cost a fraction of that with Enda, hence I recommended him to you, and anyone else who asks!

    Excellent - he's very clued up on these things. Keep us posted.

    525d small turbo problem

    Those (as you know) are the small turbo actuators, and have nothing to do with vacuum. If the OP says it won't hold vacuum, then it's the vacuum actuator on the big turbo that's faulty.

    DPF continual regen?

    Can you clarify, you say 520d, I assume this is the B47 engine and it's just a typo (i.e. not a B57)? Start/Stop not working doesn't mean it's doing a regen, there are other factors like battery condition, coolant temp, ambient temp too. I think you need to stop googling "DPF faults" as you're only stressing yourself out if you think diesel in the sump is going to happen to you. You've written a lot of stuff, but let's start with the basics. Do you have any fault codes (literally any)? It's winter time, diesels are heavier on fuel at this time of the year. You're doing short journeys - not optimal for a diesel. The BMW diesels do a form of constant regen, yes. User @Ninja59 posted this a while back. It's spot on: DPF Regeneration: Generally: Exhaust note will deepen The car will feel less "urgent" and "lumpy" The gearbox will hold on to gears for a longer period than usual MPG drop Parameters for Active and Passive Regen: There are two kinds of regeneration: Continuous regeneration: This form of regeneration takes place during normal driving. At exhaust-gas temperatures of between 280-350°C, continuous regeneration takes place in the form of a slow oxidation process. The soot particles cannot be incinerated until the exhaust gases reach the required temperature. Periodic regeneration: Periodic regeneration is performed automatically by the DDE after no later than 1000 km (600 miles). On vehicles with many short-distance drives, periodic regeneration already starts taking place after just 400 - 800 km (250 - 500 miles). For regeneration, the intake air is reduced by the throttle valve. One or two post-injections are performed. This increases the exhaust-gas temperature to about 600 °C. The soot is incinerated with the residual oxygen. The periodic regeneration is performed at all speeds. The most efficient method is regeneration at a constant speed in excess of 60 km/h (38 mph) over a period of 20-30 minutes. The DDE calculates the time for periodic regeneration from the following values: average distance travelled average driving speed temperature in the diesel particle filter values from the exhaust gas pressure sensor The last successful regeneration can be read out by the diagnosis system The following conditions must be fulfilled for a regeneration: The coolant temperature must be in excess of 75 °C the exhaust-gas temperature before the diesel particle filter must be greater than 240 °C there must be enough fuel (fuel reserve indicator light is not lit up). Whenever the reserve lamp lights up, the regeneration process is suspended. no fault codes from the air mass system, exhaust emission system and sensors must be saved in the DDE The fault codes 480A / 245700 (from F01) and 481A / 245800 (from F01) must display the status "currently not present" Constant driving speed above about 60 km/h (approx. 38 mph). The optimum speed is about 100 km/h (approx. 60 mph). One of the main reasons these cars have issues with active regen to occur is the first one, you can check the coolant temperature through the secret dash menus which will give you a live read out of the temperature if it is struggling to get past low 80's then I would begin to think one of the thermostats is on it's last legs. The car is driving fine... I think you're trying to find faults that just aren't there.

    BMW 520D F11 2011 coolant leak

    No problem, please keep us posted.

    BMW 520D F11 2011 coolant leak

    It's hard to say for definite where the leak is, but that's the EGR valve and cooler; coolant leaks here have caused catastrophic fires. Has your car been recalled at all? You can check for recalls here on the BMW site: https://www.bmw.co.uk/en/footer/quick-links/bmw-vehicle-recalls.html Also on the MOT check page here: https://www.gov.uk/check-mot-history But do not ignore this leak, or underestimate the gravity of the situation. Get on realoem.com, put in the last 7 digits of your VIN, then navigate to Engine > Exhaust Manifold > Pollutant Reduction Cooling You will see an exploded image of the EGR valve (top) and Cooler (bottom). If (and it's a big IF) the rubber hose in the picture is leaking, it is BMW part number 11718507308. If the cooler itself is leaking, try to get BMW to exchange it under the recall programme (call the service desk at your dealers).
  8. Could well be. the AGM batteries in our cars need a suitable charger, not an old-school one. Covered very comprehensively in this thread: That's not to say you've done any damage (I can't say) but it may not have even charged your battery.
  9. The engine start-stop is dependent on engine temperature, ambient temperature and battery condition (and probably a few more); normally if it doesn't work (when you think it should) you might find it's one of those things. But as @percha says, read those codes. Not all codes result in a warning you (as the driver) will be made aware of.

    F11 Bump stops disintegrated

    The airbags are straightforward, just make sure the new ones come with the little collars for the plastic pipes, as you can't reuse your existing ones. Back on the rear shock disassembly, be sure you can hold the allen key when you're loosening the nut. I use the hollow end of a jack handle, but maybe a pair of vice grips will do the job. The nut has an anti-slip insert, so won't thread off easily until it is off!

    525d small turbo problem

    Just to complicate things further... doesn't the small turbo have an electronic actuator, and the large one has a vacuum actuator? I'll confess to not having looked at mine (I have a 2013 525d) because I haven't needed to. But my old 320d has an issue that forced me to take the electronic actuator apart. It looked just like the one on the small turbo here. Some examples of both turbos removed (courtesy of Ebay): Both: Big Turbo: Small Turbo:

    F11 Bump stops disintegrated

    I used a 240V Impact Driver for that job, no more trying to undo that nut & holding the shock strut. I got this one: https://www.vonhaus.com/vh_en/240v-impact-wrench. I use it for wheel removal too, makes light work of anything really! If you have to do it the conventional way, a spark plug socket, held by a spanner & an allen key dropped through the middle of it does the trick.

    F10 LEDs or HID Kit

    Yes. It's why they're not really suitable for full beam applications (i.e. you can't properly flash your high beams with HIDs). I put an old HID I had in the projector light of my motorbike recently, as you say, takes a few seconds to get properly bright, but bright it does indeed get!

    Crisp! Nothing wrong with that, looks spot on.

    F10 Pedestrian protection system

    Yes, in short. Carly or Bimmercode are standalone, others like INPA, ISTA or ESys are free, but require a cable (D Can for INPA or Enet for Esys & ISTA).
