Just a heads up, apparently the active tanks design has been changed in the last couple of years from the original design. I believe the components are redesigned with something similar to what Xemodex rebuilds them like. A little more longevity, a little less pain in the ass. I'll let you guys know what happens where I hear from BMWCA. |

Your glow control unit is probably dead due to the plugs constantly being heated, and most likely have a faulty thermostat. Its a common failure You also most likely have a leak in your bulk head partition resulting in water shorting out your injector number 5. This will definitely cause running rough, and not turbo boost You need a new active tank.

Here's the thread about the water leak and what to do. The scr is difficult, hopefully BMW helps you there.
Injector, you may need to replace it. I used a multimeter to diagnose which ones were shorted- they should be at least 500k Ohm to ground. Here's the thread about injectors: https://xoutpost.com/bmw-sav-forums/...gine-dies.html Here's the thread on the plastic partitions breaking and shows the issue with the foam soaking up water etc. Error code 4B99 and 483D - Bimmerfest - BMW Forums |

At this rate Rob, I think I might burn it. If these things are that brittle, I'll cut my losses.
I really appreciate all your efforts, I do. But for a vehicle with 110 miles on it to be that bad, it's probably only going to get worse. If nothing else, it might save someone else from making the same mistake. |

Hey, I know- YOU should find a friend of YOURS, see if they will buy it from you! I know it makes it easier to blame the car- say it is brittle, blame BMW, blame anyone else other than where the fault actually lies. |

There is almost 100 service bulletins on these. The can be stopped by a "water bulkhead" sheet of plastic, the active tanks have been faulty for years and only just redesigned, the latest one only making it a year and a few months.
Yes, they sold it to me knowing it needed the active tank replaced. I know it wasn't neglected or abuse. I don't dislike BMW, we have a 3 series and have had several before. But... the X5 35d is a pretty delicate vehicle. I need something I can count on, and it seems like this vehicle has an engine code for"raining" or "dirt roads". |

2. As Blue points out, a simple review of the codes establishes much more than "it needs an active tank' 3. As we look at these codes, it is clear that these are somewhat common faults and- HAD THESE BEEN ADDRESSED WHEN THE OCCURRED- would be straightforward. Instead the prior owner ignored these and drove the car with known malfunctions. Water leak onto injector, thermostat fault, SCR faults, possiblie NOX faults. (I would not be at all surprised to find out the owner had a $4k-6k estimate from a BMW dealership....). But, THIS IS ABUSE. Not fixing a car and driving it is abuse- it results in further damage. 4. You blithely proceeded to buy a car with known issues. The CEL was on, you possibly took their word for what was wrong, you didn't do your own inspection. Don't rationalize this poor decision with "I'm not not one of these rich AH's that own BMWs, so I have to buy second tier cars." Beating up on BMW and the X5D now, at this point, is just you seeking to rationalize your role in your current situation. All the data you are seeing about x5D 'fragility' issues was avaiable the day before you said 'yes'. So, if you want help on fixing your car, this is the place. You will get great advice. GL |

Thanks GL, the help is appreciated. I just can't help thinking these 35d's are EXTREMELY temperamental. The active tank was bad when I bought it. The glow plug and injector issue started a week after I bought it. I can't fault the person I bought it from for that.

I bought mine with only a code for glow plug #1 already known replaced and knowing that the glow plug module needed to go. I also surmised from reading here that I needed to replace the thermostat and water pump in short order.
By the time I replaced the glow plug module a couple of weeks later glow plug #6 had bit the dust. Then I needed a new harmonic pulley, and just recently the fuel filter heater exploded and left fuel all over during a road trip. Now I have a CEL for DPF ash loading and I CANT WAIT to do the emissions delete and open the taps on this thing. I'm still happy with the car. I still plan to keep it until it just can't possibly be justified anymore. You bought a vehicle with issues both known and unknown. You need to adjust your perspective.
