Hi all,
Been having a strange issue with my recently acquired golf mk5. Its a 2.0 TDi 170, i know its a diesel, but hoping someone can shed some light on this issue.
Basically the glow plug light begins flashing after about a mile of driving from cold. There is no change in power once the light is on, but i would say the car is lacking power, having driven other 170's.
I have had it put on vagcom by a mate and this is all it keeps coming up with.
I have searched and searched the internet to no avail, the 006 short to plus seems to not be a common issue.
These flaps work differently to the petrol engines i understand. As this is done via vacuum, and the petrol uses a motor.
I have had the intake off and check the flaps, they are all complete, clean, and free moving.
I have replaced the actuator which moves the bar controlling the flap angle, as the diaphragm was split.
I have also replaced the one way inline valve going to the actuator.
I have an excellent vacuum at the pipe leading into the valve, so no leaks before this valve. But no vacuum coming out of the valve at any point. ive tried swapping the pipework around, checked the wiring from the valve back to the bulkhead area and that is all as it should be.
Im not even sure when these flaps should be opening/ closing, does anybody have ideas weather it is temperatue, or RPM replated?
Any help would be much appreciated.
Thanks Dan
