Hello together, In icy cold, my 635D started to rush a few days ago when the turbo (depending on the gas pedal position from ~60 KmH) started to operate – thought first the front window ventilation at the driver’s side would be more adjusted at once (that’s how it sounded), but it comes out of the engine compartment when listening more closely, tending to go up on the driver’s side. I then passed on leisurely (with ~120 KmH gliding is no problem), but as soon as you try to retrieve power it rushes and from d After a while, a very quiet high whistle set in when driving leisurely. The workshop has now looked very carefully at the whole thing: all hoses are tight (under load you can see them bloating too), both turbochargers build up pressure, charge air cooler also seems OK, but the DPF gives way to high counter pressure and has too high mass (although the BC has nothing to do with it). It should be noted that this DPF was professionally cleaned (burned out, etc.) about 1 year ago (after the BC had indicated this) and reinstalled with new equivalent counterpressure and mass values. Now the obvious measure would be to install a new DPF, cost point ~2K. However, the question arises why the DPF is to be returned after a year. One thesis is that the biturbo loses minimal oil, which is not noticed as a defect, but is added to the DPF. This means that new loaders would also be necessary, cost point including installation ~2.5K. But is it good then? Of course you don’t know that, so you prefer to ask in advance: Does someone have similar experiences behind them and can comment on the theses / considerations? Thank you and greetings

I have already read all the BMW R6 engines on Wikipedia, but there are still questions… If you are allowed to import only one vehicle that is not older than 5 years because of the import rules on an island in Asia: Then you probably (whether diesel or petrol) do not get around direct injection, right?1) – Has ‘DI’ become at least less difficult these days?2) – Can I avoid turbochargers with a diesel model?3) – Can I avoid turbochargers i a petrol model? And to ignore the 5 year deadline – 4) – which are the best rows of sixs between N52, N53 and M57 +newer or older engine sisters of which I don’t know yet…?5) – In itself I would prefer diesel, but there are the turbochargers, the drall flaps, the whole exhaust aria and I have somewhere gone that the 28i or 30i is so the most reliable that BMW has ever built? (did you number the questions to make the answer easier?) en…)

I had already written a long text and described in detail what was going on with me. Unfortunately this text was then completely deleted by an unconceivable touch of the mobile phone. Therefore here very briefly. I had problems with vibration in idling up to about 2000 rpm. (525d N47) At first I left the engine bearings, which brought only limited success. These motor bearings were from the accessories. A familiar thought that maybe the original bearings would be better because the Zubeh At the same time, the suction bridge was removed for cleaning purposes. It was discovered that a throttle valve was loose in the intake channel. After the intermediate plate with the throttle valves was replaced, the engine runs again as it should be. Whether the cause of the vibration in the engine bearings or the throttle valve lay I am not sure, of course, but I strongly suspect the flaps.

So people have an important question! I have planted in my 320i me n 325i engine (yes, I changed all important parts:For 325i new needs: cooler, control unit, gear unit, clutch, cardan shaft, differential, drive shafts, axles, triangle handlebars, brakes complete, brake power amplifier, wire harness, coding plug for speedometer, exhaust system incl. Kat, Lamdasonde,…) So now my question I need a full acceptance with the Tüv now? -What does it look like with the insurance – or . What is the cost of the Tüvindung ???? The engine runs perfectly (is already 5 months in it) Will only have it registered because of the security protection ! Furthermore I have a Bastuck for a 325i and that would be stupid if I had the on nn 320i registered :-)) So thank you for your answers !!!!

Hello, which current gasoline engines (from BJ 2013) usually cause little problems even with a lot of mileage? I am looking for a vehicle that should be driven as long as possible… N13? N20? B48? N55?

Hello friends out there. We need help! Our E28 m. M20-B27 engine died a few days ago, and did not jump any more. We have since renewed the pump relay, because we believed it was broken. Was apparently ok. Pump ok, filter has passage, we also have the clamps 30 and 87 short-circuited and the pump ran clean. The control current +15, from the ignition lock, under the relay is also there. Strange: despite existing control current you have to tap the relay easily so that the P Ignition spark: is not there either. Distributors looked through, cap cleaned, rotor ok. Inductive sensor on the transmission is ok. Also the encoder on the flywheel is fine clean. Despite repeated start attempts the spark plugs are still bone dry! i.e.: no petrol, no spark. And the dung box does not start! The dare is very good in the shot and has almost 90,000 on it! All plug connections are finely clean and tested. Our suspicion lies with the control unit. The car doesn’t have a computer on board, so no immobilizer problem?

Hello Leutz, had the following test. after a bearing damage at my 320i I had had the bearings changed and it held a whole 600Km, I assume that either 1 pleul is defective or the crankshaft has a HAU, does not have any further wild So, now to my question: Since I see no great sense in it my 320 hull again a SOOO large OP (event. head down because of Pleul or crankshaft renewed), I would like to install now nn 325 fuselage. (which I already have) What more do I need and what can I use from the 320 engine??? (Rump and cylinder head of the 325 is clear, although the control unit ***or is enough there?***) Does someone know more or has done this before??? THX in advance

It was finally about 2.5 weeks ago… after 5 long months of waiting I was able to close my beloved BMW 135i Coupé in my arms. Pure joy!!! Until he let me down on the motorway from Croatia to Switzerland, Slovenia on the way home 3 days ago!!!!!! According to the BMW mechanics in Slovenia a high-pressure pump is broken. Does anyone know what is waiting for me now? Can I adjust to a fault car with constant problems? I had already noticed before the trip to Croatia, when driving in, that he sometimes had problems taking the gas when starting or driving slowly…. he was also 2 to 3 times drunk. At that time I thought it was up to me to “re-adjust” to the new car. I mean, 306 horses should not have any problems taking the gas ;o) On the trip itself (my parents were on their way in their car) it was noticed that he was going to My parents thought it stinks as if the cart was spitting out pure petrol. In addition, I noticed the high fuel consumption…. 12l. But I didn’t give him too much concern – somewhere such a hell machine has to get its performance. But now I ask myself – were these all signs on the coming defect?! Does anyone have experience?? Dear greetings from Switzerland! PS; I am still immortally in love with my little rocket and hope he soon comes from Sloweni The repair is done here at my garage…

Hello, I’ve been having a problem with my 545i/E60 for a long time. The car is jerking, the consumption indicator constantly commutes at constant speed and the automatic transmission switches as arbitrarily and very hard. There are countless LMM errors in the fault memory. Finally, the LMM was exchanged in a BMW workshop (after having been replaced half a year ago) and yet all the LMM errors reappear. The workshop also looked for leaks and It is vaguely mentioned by the master that there may be something wrong with the engine control unit. However, it was claimed by him half a year ago that the automatic transmission was defective. Therefore, I can’t really trust these statements. I had the car now already in 5 workshops because of this problem, of which 3 BMW workshops. None of these workshops had even the slightest clue what this is about. Can anyone help me here? Thanks and Greeting OpKa

Hello dear forum, I’ve seen and experienced a lot, but now I’m standing for an absolute rattle and urgently need help and exchange with like-minded screwdrivers. It’s about a 530d F11/F10 N57 engine (N57d30a). The car had a defective on the control chains, were hanged and started to hit, noticed it in the speed range from 1500 to 2300 rpm. So I got new control chains (Original Ina Chains) camshaft high pressure pump, high pressure pump pe crankshaft and crankshaft oil pump. I also replaced the automatic transmission because the original ATG (8HP70) was chips. Everything reassembly engine started again. I thought 🙁 let the engine warm up, runs very quietly in the stationary gas, no dropouts purring, no side noises like knocking or beating. Engine driven 10KM with moderate speed up to 2200 rpm very neatly. At the last 500m I had the feeling (only feeling) that the power was a bit back The car is accelerated to 3000-3500 rpm. The starter doesn’t get the engine turned again. The car is back on the lifts. Everything has been dismantled, control times checked, fit! Nevertheless, the head was disassembled because two cylids did not show the full compression during the pressure test, valves had coked, cleaned and newly ground, –> now OK, engine had not set up, no valves crooked or defective visible. Engine was hard to spin, the S CHWERgang comes from the crankshaft, after ten revolutions again easier to turn I think everything was that it is still a bit heavier than usual. Motor built up again, started, runs up to 2000 rpm very well, from approx. 3000 rpm the engine goes off and the starter gets the engine only very slowly turned (like with empty battery). Hand-turned again, (starter out, engine before and back turned manually on the flywheel) again lightly gäng) starter in, engine star It runs inconspicuously. Engine runs again, accelerates, engine runs out. I don’t know any more and need help… am really desperate! What can this be about? can it be crankshafts / pleul bearings? Ask for your support, maybe someone can upload this text into the FAbucar app Thank you very much Thomas
