Hello, I am planning to leave Germany for a couple of years and wanted to buy a nice car. At the moment I am thinking of a BMW M850i Gran Coupè from 2020- 2022. However, the roads where it goes are equipped with a lot of speed bumps/ground waves that are very high. Therefore, I am afraid that the car starts and scratches. I have made a little smart and know that the ground clearance is at 128mm ex factory. Therefore the questions how can I use the car as far as possible mi t tires on at least 150mm or preferably to be safe on 160mm. Since I have found little to do with it, I have asked ChatGPT several times but get permanently different tire configurations suggested why I prefer to ask you. Maybe the one or other experience has made especially since the Netherlands also have high floor waves depending on where you are and I have already put on my M440i. If I could calculate this would be there s great. Rejoice me about your support, because it is my absolute dream car. LG m-test-driver

Hello dear BMW 8er municipality, I am currently driving a modified 125d and a modified M140i and I am now slowly preparing for a successor for these two still great cars. In question are M2, M4, M850i, or M8. I like the 8er very well (inside as well as outside). With the design of M2 and M4 I can not really be friends, even if they are technically very good cars. The large kidney at the M4 is not working at all and inside with the Curved display I ask mic h also what this is supposed to be!! On the other hand, the 8s would be optically perfect for me. Maybe a little bit big, but I could get used to it Recently I drove an M850i to the test. The car had a lasting impact on me. Not so much the acceleration or the passage (I knew what to expect), but all the more how good it was on the road and how agile the car looked despite the weight and the dimensions. So I could really be friends with such a vehicle. But ask me how good the engine is in terms of quality and stability (I would still like to do a SW tuning). The older 8 cylinders have probably caused some problems. Are there any users who can say something from their own experience or “insider knowledge”? The B58 is very stable and in my M140i it just makes me happy. The successor should of course be at least as good and stable (independent of the number of cylinders). ank. Michael

Hello together, Did someone have an opportunity to test the Runflat tires for those without emergency running on the 20 inch rims in the new 8s? The modern Runflat tires are said to have not so pronounced the previous disadvantages (less comfort, harder rolling off, track groove sensitive) But with the tire dimensions of the 20 inch tires one will probably already notice a difference with the Runflat and thus also disadvantages. The question is how big the difference is …. r Feedback grateful. Greetings convertible4ever

Hello, I’m new here and don’t know me so well. My name is Manfred and my car is a BMW F13 640d BJ2017 with 118.000KM mileage. I had a feedback action yesterday at the BMW dealer because of the airbag and AGR cooler. This was found in the error memory the BMW number 12230035934 and the BMW number 12217822100 incandescent control unit allegedly no longer work properly. So I personally have no starting difficulties up to this error memory Ausle Also no black smoke development noticed…. But I will not be unskillful to exchange these parts myself for safety reasons even though I don’t drive with this beautiful car anyway in winter. Maybe who. why you have to exchange the light control unit with and from which brand comes the original BMW part. Tap once Bosch, Hella or Beru are probably one of the original equipment suppliers… probably also from the glow plugs???? Who knows that please tell me! Moc hte buy this in replica! Thank you very much LG Manfred

Hello forum, I am interested in the M850i convertible and have been watching the used car market for some time. I notice how strong the prices fall. On average about 23,000 EUR per month. For some vehicles even 5K 2-3 vehicles that last month were between 67-68K, you can buy today for 62K. Were the vehicles so much overrated? Or is it due to the current economic situation. Should one wait or is something lazy about the series that the I’m happy about your news.

Servus, I have exchanged the coolant compensation tank today for reasons of preventive maintenance. Many already know the topic, the container can be leaked due to the thermally high load and then the coolant runs on the injectors and ignition coils, which then go defective. There is meanwhile also a changed part number and the part looks different. At first glance an additional damping / relief at the screw-down points and a a kind of drain channel, which now the coolant, which if necessary from the valve in the lid, does not run directly down (to the injectors), but leads back to the front wall. My recommendation would simply have the container replaced when replacing the spark plugs (there it must be removed anyway). Depending on the discount, the cost point for the new container is between 97 and 150 euros. In any case, also the lid, the built-in valve is known for a problem, which This is the result of a reduction in the amount of coolant which can lead to a loss of coolant.

Hello, recently I bought a 635D E64 from 2008. The car loses oil under the engine compartment, according to a mechanic this comes from the turbo – another mechanic specializing in Bmw says this can not be attributed. The car takes (one might say) reluctant gas at under 2000 revolutions, respectively: The car has an incredible turbo hole. If one gives full gas accelerates the car with felt 50hp, until it is suddenly at about 2000-2500 revolutions, you notice j a speed up more than an old Citroen and push your head into the seat. I have now heard from mechanics different things: The first I think I have to change the turbo, another thinks it is just the small turbo and the third told me it can’t be the turbo, because then I have no power at all, or the problem for it occurs too irregularly – because partly I also roll towards a crossing, want to speed up and it just happens 3 seconds nothing, with you With the result that my Bmw specialist is now of the firm opinion: The problem is electronic, all mechanical be top. Does anyone have a clue to which I can give my mechanic to get further? He is finished with his Latin. Since I am not in Germany and he also speaks bad English, I am for every tip dan kbar. I hope I have not violated any problems of order of the forum, it is my first post. With best regards.

Hello together, at the moment I drive 3 cars, as a daily car an e46 330i as a seasonal car no.1 a 350z as a seasonal vehicle no.2 an e63 M6 I am satisfied with all 3en, but for running costs I would like to reduce the fleet to 1 Alltaugsauto + the M6. Both the e46 330i (M-Package 2 + SMG) as well as the 350z(20inch, Bielstein suspension, Nvidia system + Sport Kats, Chip etc…) are great. The 3er is allerweltsfahrzeug, the 350z in the SOmmer in the dry The M6 is kept….only for what can I exchange 330i and 350z, which is just as suitable for everyday use and makes as much fun as the 330 and 350z? Thought there was an e63 645ci or 650ci….. The M6 is a KOstengrab, which I drive only about 4-5tkm in the summer, as everyday car is not so good. What do you think?

Hello dear MTler, My M6 E63 causes me grief after the installation of a Brembo GT brake system for 14 days. The brake pedal can always be pushed through before the braking effect starts. After the installation it was at about 1/4tel and 500 Km then 3/4tel until braking effect – but then extremely good, without reducing the brake pressure during the braking process. After the installation of the Brembo was aired 4 times with different methods. (1/4tel pedal path) I should then once a bissc This means that the main brake cylinder (Brembo) is changed – although the characteristic of the long pedal path could not be closed for a defective main BZ. Even with several “pumps” the pedal path does not change – so it is no longer possible to build up pressure. The brake power amplifier works perfectly, in the FS no error message. As expected after the installation and 6 I have used the dot 5.1 from Motul – that is, the brake fluid preferred by Brembo. I don’t know any more and have made the suggestion to change the hydro aggregate (2,900 €) – but that seems very unlikely – because it is “only” a distributor – if this would have been broken I would probably have rather different braking effects on the wheels. Or does the part have a brake fluid memory? Does someone of such a flaw have In various forums this topic is often dealt with – but mostly without a result being posted. Most people think – it is due to an air intake – which is confirmed occasionally. So far 15 liters of brake fluid have been sucked through, pressed through (2bar), pumped through (with the brake pedal) sometimes with no ignition, running motor. It would be best for me if one said: this is the error – but I am also grateful for every solution LG Rol and

Dear forum community, I bought a BMW 7 (G11) about three months ago. I’m very happy with this car, I bought it only because of personal conviction. I dropped the type designation, because I like the car, but it’s important to me understatement! Now I’ve noticed in the last weeks that one or the other times people look at it or feel faster in order to give you the way forward and so on. I’ve never noticed anything like that. Maybe it’s just imagination, it was convinced that most people can’t distinguish a 7 from a 5 anyway. However, I also notice that the number of half-way new upper-class vehicles on the road, outside the city centre and the government district, is actually very low (live in Austria, near Vienna). I’m really uncomfortable about this, I want to enjoy the comfort, but not notice. you have made ? Maybe it’s just the fear to be noticed and I just make it a ?!
