How do u clean the throttle body, does anyone know?
There is a way to do reduce EGR flow without getting a constant CEL light. I did all of what you did above, except I followed the advice of the Passat guys who were looking to reduce shuddering similar to what my engine had. You can put the plate in place with a 9mm hole (approx) that will reduce the EGR flow, but not give a constant CEL light. It took care of the shuddering/bucking issues I had as well. The CEL light did come on after a few weeks, but then went out after eight cycles of the engine (approx) like I was advised it would. This is an option for those that don't want the constant CEL light.PDJetta said:The PD is. The throttle plate is electrically actuated with position feedback. Its used to increase the EGR flow by blocking off the intake as the EGR valve opens. The O2 sensor is the feedback sensor to the ECU to calculate NOx content from the oxygen content of the exhaust.
For a squeky clean intake manifold on the PD, block off the EGR pipe with a plate where it exits the EGR cooler and remove the throttle plate inside the throttle body
Then, just disregard the CEL you will have from that point on.

as far as cleaning the egr- yes you can do it. look at the info here on the site regarding intake cleaning. the ALH motors and BEW's are almost identical in this regard.TDI_PD said:Well i took it to a VW dealership cause i was having cold start problems, so the replaced the glowplugs and harness and called us and said they wanted to clean the EGR and the throttle body for $400 and we just told them no, so i wanted to know if i could just do it.
I'm going to guess they are using the term throttle body for the intake.Well i took it to a VW dealership cause i was having cold start problems, so the replaced the glowplugs and harness and called us and said they wanted to clean the EGR and the throttle body for $400 and we just told them no, so i wanted to know if i could just do it.
