    E39 530D manual swap problem

    What errors is it throwing? Did anything else change on the car? ...MAP sensor etc? Do you have Testo? http://www.bimmerforums.com/forum/showthread.php?1830510-Diagnostic-program-with-realtime-graph-view It's worth logging: target boost, actual boost, target rail, actual rail, and presupply. I've seen issues like that when the rail is over or undershooting target pressure. logging presupply will tell you if the problem is before or after the CP1.

    E39 530D manual swap problem

    Are you sure you have a manual pedal? Did you have to modify it to fit the connector? I had this problem after a manual swap, but it was down to the auto pedal. For me, when maxed throttle the DDE light would come on and power would cut, regardless of speed or RPM. Turns out the auto pedal (35426786281) has a touch more range than the manual (kick down...), and the manual ECU has no idea what to do with it. The solution was to change the pedal for a manual (35426786282). The manual pedal has a couple of additional tabs in the plug socket that need cutting out before it will fit. Manual is B in this picture

    What did you do to your E39 today ?

    I basically kept removing trim, earth points, sound proofing... etc until it slid in. There was a thread about it on here a few years ago, I just copied that. There is none of the usual battery support in there any more, only the one over the top , but that thing too big to go anywhere. Getting it out again will be fun...

    What did you do to your E39 today ?

    I managed to fit a Bosch s5 015 in mine. I am not sure how the naming to sizing works, but the dimensions are 393 mm long x 175 mm wide x 190 mm tall.

    Thanks Dennis, Yes, happy to help. Send a PM whenever. I'd prefer that to filling the thread with discussions.

    I haven't had a chance to test anything yet. Parts are sat on my desk, just need work to slow down a bit.

    New turbo v2!!!

    It may be worth swapping out the rubber section of the return line; number 13 here: https://www.realoem.com/bmw/enUS/showparts?id=DP82-EUR-04-2003-E39-BMW-530d&diagId=11_7586 They age with heat cycles and multiple refits. I don't think it's so expensive from BMW.

    Touring spring conversion

    I swapped to springs for exactly this reason. Fit and forget, and never looked back. You can get the mounts cheaply through BMW, you need 2 of each: 33531093785, 33531093786, 33531093787 I went with the Eibach pro kit, relatively inexpensive and good quality. https://eibachshop.com/index.php?p1272,eibach-pro-kit-springs-bmw-5-touring I actually have a spare set of rear springs, if you're interested PM me. (was going to fit them to a friend's car, but he does a lot of towing so we put fresh SLS bags in at great expense...)

    Yes, I knew that part, thanks. It is the duty cycle that I was unsure of

    Thank you. This is what I'd heard from a few places. I will look into it. I plan to measure the PWM for the N75, and I have a 12 V function generator to test the range of the electronic actuator.

    @Clavurion Thank you very much! That will save a lot of time. Do you know if the duty cycle of the control signal needs changing in the map? The documentation is a bit misleading: Here (page 140 and 141) the duty cycle is listed as 30% to 95% for both the E39 and E38, but WDS has it at 5% to 95%. For the E60, WDS has 10% to 95%, with 10% vanes fully opened and 95% vanes fully closed.

    Thank you. The injectors are from an early 535d, not sure of the part number, sorry. I have DLLA 145 P 1655 Bosch nozzles (145 spray angle).

    I would like to covert to an electronic actuator, because of boost control issues at altitude. It’s actually fine in the UK, but I live in Switzerland and most interesting roads are at or above 1000 m (- ~0.1 bar atm), where it gets a bit laggy. Vacuum pump is good, so I pretty sure it is the actuator. I found a complete turbo and actuator at a breakers, so I have something to test now. There is a Slovakian guys selling kits to adapt the E39. I may well end up getting one. But, I thought it would be fun to figure it out for myself. I was going to start with what was done for the E38 740d. I saw some posts from you about this a while ago, but attachments are long gone. If you have any input, I’d really appreciate it

    Thanks Dan. As is yours. Yeah, I was quite sceptical of Powerflow, but the Totton guys came highly recommended locally. I looked at a couple of fabricators work before choosing them.
