Hi great videos and useful info. I have a 320d n47 and I've constantly had my management light on the dash. I removed my dpf, blanked out the egr , blanked off the port on the side of the air filter box and I've ran a, rubber draught hose, down from the top end breather port and out under the car. So now the engine can breathe in clean filtered air , without any egr soot going back into the inlet manifold , there is no sticky , oily residues going into the inlet system from infront of the turbo and the exhaust system is not clogged up with the dpf. I've also removed my intercooler and all the pipes, cleaned out all the oil that had accumulated from the breather hose and I've cleaned off all the rubber seals. I've also cleaned the throttle body.the only thing to clean out now is the inlet manifold itself and the swirl flaps as they will be clogged with oil and egr soot. The engine is running much more responsive but I'm still have the issue of low down turbo lag , my MIL is still on and I get a reduced power light if I really boot it. My question is , what do you think about blocking off all those vacuum lines and just running one line from the turbo actuator to a port on the inlet manifold or just after the throttle body ? I did a similar thing on my e39 525, only i connected the fuel pressure regulator to the the manifold as the car was normally aspirated.
Hi, if you have blocked the EGR off you will need to have it mapped out to get rid of the EML light. I’m not sore blocking the vacuum lines will be a good idea. The vacuum system on the E90 is all interconnected with turbo and active engine mounts. That part of the issue I’m having I think.
@@NeilsCarsAviationTravel yes, I forgot to mention in my massive comment that I had it all mapped out. , dpf , egr and I had the power opened up aswel. I think what I might do is just run a new hose from the turbo actuator to the inlet manifold and test run it , just to see if it makes any difference. If it does I'll disconnect all them pipes and blank them off. I'll let you know how it goes and make a vid of it to . Cheers mate.
Hi very good video. I have a BMW 525D. I had a tturbocrash and after replaecing the turbo I have got several drivetrain errors under 3000 rpm and over 3000 rpm. After watching your video I understand my booster rpessure solenoid mus replace. Thank you very much for your best and helpful video
Hello, I want to ask about my car, did you get errors, the car is running erratically, with error code 3F00 A 3F03. It is a BMW X5 E70 35D XDRIVE 2010, the rpm fluctuates, too. Thank you for any help
The 3F00 and 3F03 errors seem to be more related to the MAP sensor which should be in the manifold. This reads the pressure in the manifold. It could also of course be a leak in the inlet side if you are getting a erratic idle. Maybe worth having a smoke test done where smoke is pumped into the inlet system tot see if there is a split hose or hole in the manifold.
@@NeilsCarsAviationTravel hi, that's right, the Diagnostics point to the sensor of the fuel pressure signal and I forgot to write that the car has a clutch and the revs rise to idle, it behaves as if it were driving in 3rd gear, but it behaves strangely and even today I was surprised by the error code 42DE. Otherwise, it starts without the car does not smoke problem, it happened to me that the DPF filter alarm went off twice, but then not anymore
I have the same boosting issues like you descripe: I have a BMW 525D Bi-turbo F11 xdrive 218 Horsepower. No power under 3000 rpm, no power over 3000 rpm. I got man drivetrain errors if I accerrate a little bit. I ran Autofix es910 diagnostic and the same error log came back saying short circuit on the pressure converter on each rescan. Should I replace the erg control value too along with the replacement of the pressure converter?
What is the name and partnummer of the second device you show on this video in the beginning of the video? I have to solve my problem with my BMW? Do you know which size is on the hose on the pressure converter. Maybe I have to change the hose as well when I replace my Pressure converter. My car has passed 152000 km.
The smaller one is also called an EGR control value. This is the one I bought. www.ebay.co.uk/itm/113452311646?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=5hKVr8gXTgG&sssrc=2349624&ssuid=ENW11iTvRY2&var=&widget_ver=artemis&media=COPY

Hi Dave, have you had it plugged in to get codes off the ECU? If you look at my other Alpina videos you will see I have been chasing my tail trying to get to the bottom of lack of power and limp mode issues. I’m having the car MOTd in 2 weeks so will be back on diagnostics asap.

What’s your point? 535d is only around 1 second quicker to 60 and doesn’t handle as well. They are plenty fast enough if running correctly. BTW a 535d with bad pressure converter valves will be as fast as a 520d so best to have them sorted it faulty.

On the black cover over the pressure converters, what fasteners hold it on as you cannot see them due to them being recessed

have replaced glow plugs , glow plug module , charge pressure sensor , cam position sensor, turbo and engine breather ; also fully serviced it .
am getting jerky or hesitant acceleration if i wide open throttle at lower RPMS sometimes even half way through the RPM range , occasionally the car goes limp with CEL , codes are showing MAF issue .
i had a garage swap out my MAF, egr valve and egr solenoid (pressure converter) with a used pair from a 330d , cars running better but still has those issues just less frequently .
garage is saying my boost is too low and sometimes too high , they think it could be a software issue ; however i'm thinking they aren't doing thorough enough testing to make sure it isn't simple vacuum leak somewhere in the system ...
