I just purchased a 2007 rav4 2.2D with the 2ad ftv engine about 4 months ago. Car has about 180k km on the clock and i have started having some issues with the EGR system.... The turbo keeps realesing the pressure and the car is jerking at low rpms and low boost, but is fine at wide open and high boost. I keep getting the p0400 code and it's for the EGR system malfunction and the car goes into limp mode. I get an error code for the ABS and 4x4 at the same time as well. ( DTC0C1201, a vacuum code i believe?) I have changed the EGR valve and did not help. I also took off the inlet manifold to clean it since there was a lot of build up in it. After cleaning i drove the car for about 1 hour and was hard on the throttle and it was fine except for the jerking from turbo was still there. After the drive i was pulling in at home again and it goes into limp mode again with the p0400 code...
Anyone have any experience with this? I know there's a "second" EGR valve and a cooler located behind the engine, but i guess i would have to remove the DPF to get to it? Could those be causing the issue?
This is probably slightly confusing, as no RAV with 2AD-FTV of 2007 vintage was fitted with DPF in the UK. Only the "T180" engine "2AD-FHV" was fitted with DPF, at that point.
There was the option to fit FTV and DPF together in other markets and as you are quoting "km" and not "miles" I expect you are in "another market".
C1201 DTC is related to VSC/TRC and I believe only generated because of the engine problem. VSC/TRC relies on being able to command torque demand from the engine and it's basically saying VSC/TRC is not available, because there's an engine fault and engine torque demand therefore cannot be relied upon and therefore VSC/TRC can't function properly.
The EGR does I believe have some position feedback to the Engine Management System and if the EGR moves too slowly (or not at all, or reported as such to the EMS) you'll get the P0400 DTC.
You might also want to take a look @ VSV (vacuum switching valve) and VRV (vacuum regulating valve).
