Can somebody please help I have a Vauxhall signum 1.9 CDT I 2006 I’ve had to swell flaps taken out and blanked
Car was running ok but the light with the car and spanner came on and went in to limp Mode . When turn off engine and restart it was fine for about 5 miles and would come on again
Now engine management lights on and won’t come out of limp mode Cheap diagnostic kit comes up with inlet Manifold airflow solenoid malfunction p1110
Where is this situated
Any advice would be appreciated

Could be wrong but think that’s the swirl valves motor. There’s a sensor on it.

You blanked the valves (I did similar)

When you blanked it, did you remove the motor linkage you the swirl valves ?
If not it will be stuck (not hard to disconnect (it’s straight down under the egr valve below the next lip through a gap. I pushed linkage off with a long screwdriver.

If it is the swirl valve motor you need a replacement motor or it mapped out (get egr mapped out same time and shouldn’t cost extra )
Only way to clear as a major emission fault.

When googling, search pretending you have a vectra as much more common to find help.

I took the linkage off but left the motor on and plugged in
I can’t find anything about this intake airflow control solenoid
Where it is or even what it looks like

Looks like with age the motor has seized or out of range.

Google the code and vectras rather than signum.
How many other motors/solenoids are in the system?

I’m not sure think I’m going to have to pay for someone to come and find out what’s going on with it.
Just hope it won’t cost loads
I called Vauxhalls today and they said they didn’t know what it was lol
