HDi fun
TC ModFather
I have a minor oil loss from the air 'doser' - it's the device in the intake side that chooses whether to feed the car cooled air (from intercooler) or the hot stuff directly out of the turbo.
It has been replaced about 35,000 miles ago to solve the same problem. I'm told that the problem is relatively common on remapped 406 diesels (of which mine is one). I'm guessing due to higher intake pressures overcoming the resilience of the device and it's seals, gaskets etc.
The car is a 2.2 HDi with a custom remap which basically increases fuelling and boost pressure across the rev range but in a progressive way rather than the brutal changes that plug in boxes do. In turn this gives more torque and thus more power and more performance.
Can I get around this problem by fitting an intake kit? Would doing so interfere with the operation of the particle filter? Or would it not solve the problem because the intake kit doesn't replace the air 'doser' (it's a French to English translation) ?
THe obvious answer is to reload the factory fuel/boost map but I do like the extra torque that the ECU remap provides.
The oil loss is fairly small and I don't need to top up between 12,000 mile services - perhaps I should put up with it and just jetwash the front of the engine occasionally?
Any ideas?
Thanks,

Paul.
