The procedure I was told was from a BMW mech, i'll see if he can get one down on paper.
As far as drilling holes and adding 3rd part dials ...
I hate my car right now !
I've replaced gearbox , turbo's all associated pipework and actuators, pretty much the complete vacuum control system , seals ,pipes , controllers, thermostats , sensors the lot as well as the run of the mill stuff .. tyres brakes oil etc . I have spent a small fortune on this car to keep it on the road. When the DPF failed, having it mapped and DPF bypass fitted was the cheapest option ( apart from fitting a s/h DPF with no guarantees). Now with all the unforeseen issues with cracked EGR coolers ( purchase of and time fitting ) , the final straw for me and this car was the hydro locking and bending of a con rod when the last but 1 EGR failed in spectacular fashion.
As it happens and it's quite important to note , the hydrolock occurred not when driving ( boost and coolant pressure would counteract each other ) but when the car was turned off and the coolant still under pressure seeping out over a period of time which then pooled. Starting the car with this amount of fluid in the system must have somehow found it's way into the inlet. ( bearing in mind that the compression is that high you'd only need a thimble full of water to do the damage)
Sadly my wallet cannot take any more shit. I'm still driving it with it's bent rod as a form of punishment for causing me so much grief... and it's already paid me back for doing that , reckon the master cylinder seals have gone as the pedals gone all spongy and can push the pedal to the floor if I hold it under pressure for long enough.. not a vacuum problem because it's all been replaced.
When I have the cash to fix it the con rod .. it's getting repaired then chopped in for something else. I love the 35d there isn't a car on the market that can give impressive power, torque and MPG in the same sentence but it's like having a high maintenance trophy wife. It feels great when your out and about, but the behind the scenes wallet raping just isn't worth the grief.
