The glow light flashing and a reduction in power is a classic symptom of an EGR valve problem on VW group diesel engines, so it sounds likely that the mechanic made the right call on replacing it, especially as your car is working again. If your friends are saying it wasn't an EGR valve they are probably wrong. If your friends are saying that the valve could ...

Nobody here can tell if your EGR value is irreparable damaged or not. Some valve models are frail and easily damaged, others are quite robust and cleanable until the damage is too big. Most of the time the failure is that the valve is full of carbon and the actuator cannot move the vale. Some models are quite robust and just seize, but have a good ...

OK, so the first thing is that the continuity setting on my multimeter doesn't work very well.. I redid the resistance tests using the regular Ohm-meter setting and was able to identify all the pins: EDIT I went back and remeasured both the original EGR and the replacement one while both cold and off the engine. My updated measurements make me suspect that ...

I would use your original egr. You don’t know if the other one works - you even mention the possibility of water ingress. Of course you can fit the egr from the scrap yard and then get to change it later when you find it does not work.

So I did some testing and saw that the waste gate actuator is not getting any vacuum on start up. It should be getting vacuum enough to fully close it on startup. I also manually held the waste gate closed while having someone hold the rpms steady at 3000 and verified that the turbo itself is working properly via scan tool showing the requested turbo ...

You don't state which model you have, so I'm conveying information relevant to the W124, W202 and W210 series. If your engine is a OM602 or OM605, then the EGR is notorious for clogging up the intake runner. Disabling the EGR will improve performance because it leaves the butterfly valve in the intake runner fully open, with the added benefit of never ...

Contrary to some other answers claiming that BMW engines do not have an EGR valve, in fact the diesel engines do. Here's a link to the parts catalog showing it, and an illustration on its placement: http://bmwfans.info/parts-catalog/E90/Europe/320d-M47N2/browse/engine/pollutant_reduction_cooling/ Looks like it's on the front of the engine, between the ...
