I am still trying to troubleshoot my limp mode. I started by cleaning the EGR valve. When I took it off, I found a 5-7 sq.cm piece of black plastic which looked like it broke off something. I could not find it's origin, but I saw plenty of gunk in the manifold. Anyway, I started by cleaning the valve and brought it to a condition it moves when pressure is applied from below (I guess EGR inlet). The spring seems to be strong, but it moves. The car was still entering the limp mode after first kickdown and had to be turned off to reset. It could, however rev high in P, emitting plenty of black smoke. I next decided to clean the manifold. Upon removal I found out the swirl valves had been removed, and so was the servo. In theory that would have been enough to put the car in limp mode, but the funny thing is it was fine when I bought it (2 months ago). Anyway, after I managed to assemble everything the right way (Thank you to Alex and Malcolm) the car drives, but stays in limp mode only. Just in case I tried to install a 5kohm resistor in a swirl motor plug (between a middle and pink wires, I think the white wire is ground) but it made no difference. My next suspect is the turbo. I checked that it spins when turned by hand, that oil reaches it and that the actuator arm moves when pressed down. What I do not understand, what regulates it? Exhaust gasses should spin it no matter what, I can't see any valve between the manifold and the turbine. Is there some kind of a flow diagram/manual available?
