Q: How to check the EGR solenoïd ?
A: With an Ohm-meter; open or short circuit = bad, typical R = 8 ohm (as written on)
This answers Your original question...
You'd better open a new post with your real issue (in the tittle as well), where You would give FULL information, the very minimal one being engine type (don't give a s**t about the colour, lowered suspension etc. ;-). No need to make a long story, but don't shorten it either, i.e. "my car is limpy".
That would look something like this:
Post tittle:
MJD loss of power
Msg:
Hi there, my name is Zorglub from Mars and I'm new on this forum.
My car is a Grande Punto 1.3 MJT 90 bhp, year 2008 100% stock (no mods).
The daughter brought the car back from a visit to a friend, telling that she was missing power and could hardly accelerate to reach 120km/h on the highway.
There is a warning light ON at the dashboard and a message saying to "control the engine" (or similar). Engine start perfect, makes no special noise and doesn't smoke !
I have a little experience with mechanics (not two left-handed ;-) so could perform some checks if needed. I believe I could have error code read quite easily...
Any suggestion warmly welcome,
Regards, Zorglub
Let's see if someone would reply to this fake post (actually it really happened to me, exactly like describbed), then You'd know how to ask to get any help...
Regards, Bernie
ps: I fixed the problem describbed for 80 €cts ...
