Hi. I recently did an egr delete kit on my 1.9 tdi 130 . After realising it was more trouble than its worth with pipes coming off and warning lights coming on. I decided to take it off.
just before this though I had major boost problems, with constantly having to have the code reader plugged in while driving to clear the fault codes to get it out of limp mode.
then when it was it filled the road behind me with black smoke.
when I cleaned and put back the egr valve, the black flap actuator on the side kept closing the egr and stalling the car immediately.
So I had a couple of the hoses swapped round, brake servo vacuum and solenoid pipe, as they were identical thinking I'd mixed them up. Now it starts and runs, but if I leave the vacuum pipe attached to the black actuator on the side of the egr, eventually it stalls the car.
but if I leave it off, when the car is warm and I go to restart it, it shakes like a tractor!
I thinking by blanking the vacuum hoses off I've broken one of the solenoids. But which one, as its a maze of t connectors.
any ideas people?
