hi my name is brian, i have a 97 525tds e39 and at the moment im havein a problem with it, and hope some one has any idea as to what it could be. here goes, most of the times when i accelerate there is no power as if there is no boost and then after a while along while it will suddenly kick in but not all the time. the other problem is when i turn the engine off there is a sound of a fan running behind the clock/radio area which is draining the battery of power. can any one help me pls.

thanks brian

Hiya Brian...

The EGR valve can cause these power symptoms, it's a general issue on all diesels... You have two options...

1 - Remove it and clean it with a high-alcohol content fluid such as Isopropyl (Not Tennents Super Strength).

2 - Remove it and use blanking plates.

Do you have any other symptoms such as Excessive exhaust smoke?

When was her last Service?

      105C thermostat replacement

      As I understand the wiring diagrams and operation Item 9 on the thermostat housing is the sensor which sends its signal to the ECU for interpretation with information from the map sensor. Information from item 12 (1st drawing ) is also used to provide average temp across the cooling system. As far as I am aware the Thermostst is independent of the sensors and operated by expanding wax material internally

      BMW 318i boot locked can’t get into

      Errr not clear here Donald Plastic "L's" with short rubber hoses ??? Distilled water/Ionised water should only be used in an old style lead acid battery. The Rad and engine coolining system should be filled with the correct coolant mix to prevent cavitation and the danger of freezing in low temps. Coolant should be part of the cars regular maintenance and changed every 3 years or so. At that time all hoses and connectors should be inspected and changed where necessary to keep everything in tip top condition. Changing parts can cause as many problems as you may think your solving

      BMW 318i boot locked can’t get into

      Update: I checked my battery and it charged in 5 minutes, so I don't have to find another alternator. All seems to be OK except for the plastic "L"s with a short rubber hose that bypass the HV/AC solenoid. Those get clogged after @ 150,000-190,000 miles (if distilled water wasn't used) and cause air pockets that try to burst radiators. I have a few more brass "L"s, so now I can throw the plastic ones away. I have to be careful I don't fog the windows though, without heat or cool.

      105C thermostat replacement

      You are absolutely right. The strange thing is that when I put the chassis number on the realoem it shows that the temp sensor is not applicable on my vehicle. I will physically check for a sensor. In the meantime, do you think that the removal of the MAP activated thermostat will effect the temp gauge on the dial instrument item 6? I am tempted to add a dummy resistor , 11.5ohms - 13watts , to simulate the MAP thermostat. Your thoughts?
