DDE Isssues Again
This is my old thread where i fixed the loss of power by replacing the turbocharger module. (https://xoutpost.com/bmw-sav-forums/...or-issues.html) Today i went to check for any error codes becouse i noticed in the morning only on first start the car would shake a little and drop rpm but then it will run very normal. The car has DPF disabled, turbocharger partially reubuild + turbo module replaced. it's a 2006 X5 E53 3.0d I found 3 error codes : https://i.imgur.com/oE5p8o2.jpg 1. 0041AA DDE: Sens presione di aliment 2. 004B10 DDE: Regolatore silenzionata 3. 004B11 DDE: Regolatore silenzionata By clicking the first error (0041AA) to read more details this is the result : https://i.imgur.com/dAh2TmC.jpg By clicking the third error (004B11) this is the result : https://i.imgur.com/N2DVhQr.jpg And the injectors seems to run very well at the moment , this is the result : https://i.imgur.com/6RELpKk.jpg Any help or suggestion what can i check next ? |

Replaced the Charge Air Pressure today that is located on the right side of intake manifold.
After this i went to another mechanic that checked the codes on the car , he explained me that BMW ISTA D has 3 types of memory (shadow memory,regular memory and another one). The car was showing different hidden errors like EGR , Intercooler Sensor , Charge Air Pressure so he deleted them from memory with another software. He then had to reset all the values of EGR , MAF , MAP etc. Car drives better now and the codes did not come back yet. Will have to drive for at least 100km or 200km so the car adapts agains the values. Fingers crossed |

It's not ISTA D that has the various fault memory locations - they are in the car itself. Different software applications (ISTA D, INPA, DIS, PASoft etc.) present the codes locations and values in slightly different ways and reading them etc. often requires some degree of interpretation.

In my case this code appeared when i took the DPF OFF the ECU. I sent the turbo for a check becouse i thought that was the issue but after doing all the required fixes on the turbocharger + replacing the turbo module i thought it was back to normal but NO , the car was the same .. low on power This guy who works with ECU's , transmission modules and basically everything that is electronic had the latest version of Launch Diagnostics that was able to read all this kind of memories it even showed EGR issues stored on the car memory.... He then told me if the values of MAP,MAF, EGR were reset , i told him no so he runned a adaption on them or something like that. the car was really weird at first but it started gaining it's power again ... He does custom ECU's and told me if the error appears again maybe it's becouse of bad MAP , but normally only a. DPF removal should not trigger such error This error is a nightmare |

UPDATE:
Code appeared again , this time we tested the vacum line and it didn't react very well on car start up. 1. We found that one of the hoses on the Vacuum Pump Tube Pipe that is located just below the intake manifold had one broken pipe. Part no #11667798312 2. We found that they were placed incorrectly and that each of this hoses had different pressure. Based on the scheme from real oem : https://i.imgur.com/8z09aAs.png First Pipe it not usable becouse i have electric turbo Second Pipe goes t EGR Pressure Converter Third Pipe goes to Engine Mounts Fourth Pipe goes to Intake Manfold We replaced that part,cleaned the erorr code memory and hopefully it wont come back again @wpoll is the placement right of this pipes ? |

Here's the factory manual diagram... for the EU3 spec at least - not sure if it also applies to the EU4 version...
1 Electric changeover valve 1a Vacuum hose from electric changeover valve to damping-controlled hydraulic bearing (DSHL) 1b Vacuum hose from suction air distributor to electric changeover valve of damping-controlled hydraulic bearing (DSHL) 2 Electropneumatic pressure converter (EPDW) 2a Vacuum hose from suction air distributor to electropneumatic pressure converter (EPDW) 2b Vacuum hose from electropneumatic pressure converter to exhaust gas recirculation valve (EGR) 3 Exhaust gas recirculation valve (EGR) 4 Vacuum line to engine 5 Vacuum hose from vacuum reservoir to suction air distributor Another view.. (and this one is definitely EU3 so ignore the turbo boost control...) E46 / E39 / E65: 1 Vacuum hose to vacuum tank 1a Vacuum tank 1b Vacuum hose from vacuum tank to pressure converter 1c Pressure converter on turbocharger 1d Vacuum hose from pressure converter to vacuum unit 1e Vacuum unit on turbocharger 2 Vacuum hose to pressure converter 2a Pressure converter for EGR valve 2b Vacuum hose to EGR valve 2c EGR valve 4 Vacuum line E46 only: 3 Vacuum hose to electropneumatic pressure converter 3a Electropneumatic pressure converter 3b Vacuum hose to vacuum unit on radiator blind 3c Vacuum unit on radiator blind

The first diagram matches mostly , so i guess everything must be set correctly.
My E53 has no vacum reservoir, it has only 3 usable pipes: http://bmwfans.info/parts-catalog/E5...acuum_control/ 1. EGR Pressure Converter 2. Engine Mounts 3. Intake Manifold I have to drive it for a while to see if any codes appear Last edited by raydhimitri; 04-08-2021 at 03:42 AM. |

The number of ports varies from version to version (3, 4 or 5 ports). but it makes little difference - all the ports on the vacuum manifold are at the same vacuum level.
My M57TU has only 3 ports also (can't remember exactly though): - 1. Turbo Boost Vacuum Reservoir (then to Turbo Boost Pressure Converter) 2. EGR Pressure Converter 3. Engine Mount Pressure Converter Pretty sure I don't have any vacuum line feeding anything on the intake manifold (swirl flap control etc.?)

Mine has a line that feeds the intake manifold to open swirl flap This is the old picture with the old vacum line : https://imgur.com/Y5pi2hq This is the new one : https://imgur.com/wbTQvGt Last edited by raydhimitri; 04-08-2021 at 06:33 AM. |

If this won't work i will have to flash my old ECU File before DPF removal from my local mapper.
