  1. I don't believe even the latest design of cooler that is being fitted actually addresses the potential fire hazard. What's more, BMW is not the only manufacturer to be experiencing this kind of issue with EGRs, but after so many cars caught fire in Korea, BMW really came into the firing line. They now face a massive global problem. To maintain their image, their only option was to do the recall, although they are trying to minimise the number of vehicles involved in an attempt to play down the extent of the problem. I expect the replacement parts being fitted are basically just newer versions of the original valve, which are also likely to fail in due course, so perhaps even these will need replacing again. I am surprised that so little has been publicly discussed about the engineering solution. I asked earlier in the thread, what part number had been fitted on recalled cars: surely we need assurance that this new part will solve the problem? After reading a Korean publication a couple of weeks ago, I think the solution will necessitate a complete redesign of the EGR cooler mechanism to incorporate a separate radiator to prevent the coolant from boiling:- "A public-private investigation team under the Ministry of Land, Infrastructure and Transport had already raised the need of an additional recall for defective designs in exhaust gas recirculation (EGR) system when it released its examination report on BMW fires on Monday. The team confirmed that the major cause of the fires was a leaky EGR module, the same conclusion that the German carmaker came to, but disputed BMW’s claims that changing the faulty hardware resolves the issue. The team said there may be a fundamental problem with the EGR design and a simple replacement may not completely resolve that. “We spotted coolant boiling within the EGR cooler, and we think the boiling is due to a faulty design of the EGR,” the joint investigation team said in a statement. “If boiling continues, this could lead to a crack in the EGR cooler, [making them leaky.]” “New EGR systems won’t lead to fires right away, but the team found that after several years of constant driving heating up the EGR cooler, a similar fire could reoccur as long as the design stays the same,” a spokesperson from the Land Ministry said in a phone call on Wednesday. “We demanded that BMW come up with an explanation regarding EGR design.” The joint team also said the intake manifold connected to the leaky EGR coolant should be recalled as well after check-ups if it has been polluted or weakened by a mixture of leaked coolants and engine oil sticking to pipes. The team has delivered its research findings to the carmaker, which has to consult with its German headquarters and come up with a recall plan. In the meantime, an increasing number of BMW car owners are signing up to file a suit against the company. Barun Law, which is currently preparing for a class action suit against the carmaker, has collected around 1,000 car owners who would like to take part in the suit as of Wednesday. The Korea Consumer Association is also preparing for a separate suit and has gathered roughly 2,000 participants."

    F11 Reliability

    F11 Reliability

    Having previously owned an E61 with the same M57 engine, I am familiar with the diversity antenna problem, as well as swirl flaps, clogging EGR, cracking stainless exhaust manifold etc. I don't know about the F11, but my F07 has the N57 engine and it is a huge improvement over it's predecessor and doesn't have those problems. Apart from the EGR, as 535i Andrew has mentioned, I haven't found any weaknesses yet. The 8 speed autobox is so much better and I don't think the F series are plagued with iffy electrics in the same way the E series were. If I were looking for a 60/61 plate F11, one thing I would be wary of is whether the front wishbones have been replaced. Mine were shot at 95K miles and I suspect were the reason the guy I bought from was selling the car - BMW would want thousands to do this work, although of course you could get it done cheaper elsewhere.

    Farewell and thanks

    To echo my point from earlier about how modern cars seem to conform more and more to the same design specification, I can see that even Skoda have started imitating the Hofmeister Kink next to the C-pillar! I have nothing against Skodas and that is a nice looking car, but in reality, it could look like any make you wanted if you just changed the headlights and grill.
  5. Does anyone who has had their EGR cooler replaced know the part number of the new part? Quite a few people seem to have had these replaced pre recall and then have had them replaced again via the recall. The number is visible on a white paper sticker on the front of the cooler. Mine is 7805446, which I think is the original part number from 2010. I believe this part was superceded by 7823210, which was fitted on N57 engines from March 2011. Not sure when later versions came in. It looks like the N47 engines initially used part number 7805447 and then 7810751 from 2012, but again I don't know what subsequent updates were applied. Surely, the only criterion for determining whether a car is recalled, should be whether the EGR cooler on the vehicle is potentially faulty or not? In which case, it should be immediately evident which cars are affected and I don't understand why BMW want to check each car their workshop. They have known about this issue for some time, so presumably they know which part numbers can fail and which don't. Of course, if a car is indeed fitted with a potentially faulty part, then they will need to check if it has actually gone bad and whether the manifold also needs to be cleaned or replaced. I suspect BMW are using a lot of smoke (excuse the pun) and mirrors, in an attempt to play down the numbers involved in this debacle. In simple terms, my point is that any version of the cooler that has been known to develop an internal leak, should simply be replaced with one that has not been known to leak.

    The E34 was a sublime car and way ahead of it's time when it came out. The older generations of BMWs really stood out on their own against the competition and I have such fond memories of my old E28 525e in particular. Cars produced today conform to the predetermined requirements of their target sectors, resulting in a bland mix of sameness. BMWs have to be price competitive, so increasing numbers of their components are made in Chinese factories that make similar parts for other cars. Having said that, I still believe BMW makes the best 6 cylinder engines. Modern Skodas are good too. Hope you enjoy it!

    CIC sat nav 7 digit postcode search?

    I tried inputting a postcode again today and realised that my original post was slightly misleading. It is possible to enter the full 7 digits, but the last 2 are not acknowledged, as Digidick described. Therefore, the system will only direct you to within a few miles of the destination, unless you select or add a street name. Even then, if it is a long road, you could still end up miles from where you want to be! It seems the only way I can input a precise destination is to find it using the interactive map, which is ridiculously time consuming. You can then select that destination, which is a bit pointless, because by then you have already found out how to get there! A basic Tomtom or Garmin of the same era was so much better. Thank you all for the info. I now accept that a firmware update is the proper solution, but I'll probably just stick with using Here maps on my phone unless there is cheaper alternative to BMW Service. Perhaps this is something a Coder could do?

    Smoke / EGR

    Here is a picture of the EGR valve on my old E61 before I cleaned it. I went on to do the inlet manifold as well, which was also in a shocking state. The deposits near the cylinder head were gooey, as described by Matthew, but the area where the exhaust gases enter the manifold was lined with hard, dry soot, similar to the stuff in the EGR valve. That was an M57 engine after 123K miles, so an extreme example, but this is what recycled exhaust gases can do to diesel engines. You can probably imagine how doing this job improved the performance!

    Smoke / EGR

    From what I've read (and experienced) carbon/soot build up in the inlet manifold is a constant problem when exhaust gases are recycled, because the reduction in cross sectional area obviously restricts the ideal flow of air and fuel mixture. The big deal about EGR coolers failing and the reason for the recall program is because glycol getting into the manifold sticks to the carbon, causing a build up of 'clumps', which get hotter than the usual dry lining of soot causing hot spots which melt holes in the manifold or even catch fire. The mechanism has been demonstrated recently in Korea if you want to check.

    CIC sat nav 7 digit postcode search?

    OK, so perhaps the penny is starting to drop now. Am I right in thinking that all the people who have reported successful updates to include the full 7 digit input, have had their firmware updated by BMW? I imagine the majority of them have not owned their cars from new, so are unlikely to know what and when this happened. Is this the sort of thing that BMW would do routinely, say when the car goes in for a service? If so, I am surprised that mine has not been updated, since it had been serviced exclusively by BMW until I bought it a couple of years ago. I'm now wondering if they might oblige when it goes in to have the EGR cooler checked in a couple of weeks. Don't really want to pay more than a hundred quid for the privilege.

    CIC sat nav 7 digit postcode search?

    That's similar to mine, except where you have City/Postcode, I have Town/City. So I just start with putting the postcode in that line and it accepts it up to a point when I have to accept one of the streets or places listed on the right.

    CIC sat nav 7 digit postcode search?

    Thanks for the offer, Digidick, but no I don't have a lifetime FSC code. The map update I got was like this one, but the 2017 version:- https://www.ebay.co.uk/itm/BMW-CIC-NBT-SAT-NAV-UPDATE-PREMIUM-2019-1-FSC-CODE-MAPS-f30-f10-e90-e92-e60/173045025732?hash=item284a498bc4:g:y6UAAOSw8L5b4BjS:rk:2:pf:0 A demo of 7 digit postcode input shows an option on the second line of address input for 'postcode', but mine doesn't have 'postcode' listed as an option. Does yours?
  13. Some folk seem to get the 7 digit postcode search option automatically when they update their maps from the 2010 version. For me, the maps updated fine, but I still can't input a full postcode. The second line of address input calls for 'Town/City' without any mention of postcode. If I try to put a postcode in this line, I can input 5 digits and then a list of places and street names pop up on the right hand side and I am forced to select one of these, otherwise the destination selected is just the 5 digit postcode - which is useless. I have professional CIC sat nav and it has the tick in the lower left corner, which apparently means I shouldn't need to update the firmware. In 2017, I bought the Premium West Europe maps 2017 update from Ebay, along with an FSC code to enable my system to be updated. It took me ages to do, but eventually the FSC code was accepted and the three USB drives installed successfully. If I go to options in the I Drive, the version is described like this: Has anyone here done this procedure and managed to get the 7 digit postcode search option? Matthew mentioned having this facility on his CIC nav, but I think he paid BMW for a software update. I looked on the BMW website and found a free downloadable software update, but after reading up on this, I think it is just something to do with the phone/bluetooth software. I'm no techie, so don't want to attempt any coding , flashing or anything risky!

    Smoke / EGR

    Pleased for you that they are dealing with it promptly and it should be a no cost fix. The EGR cooler will include a new EGR valve, which is a good thing to have done anyway. If I was in your shoes, I would be asking for confirmation of what they are doing with the inlet manifold. Since you have had the smoke symptom already, the coolant has certainly contaminated the carbon deposits in the manifold, creating a fire hazard. I believe the minimum they must do is walnut blast the manifold to get rid of the deposits (which is also a very good thing, since the build up of crap in there will be hampering your performance and economy). However, if some of the stuff caught fire, that may have damaged the manifold and possibly even burnt holes in it, which would necessitate that being replaced too. Bet your glad it's covered by the recall!
