Help, code P1411
I got this cel code appearing a few times last month then it went away.
p1141 doesnt really point to anything specific and i 'think' its air pump related.
Yesterday the code appeared again, i have reset the ECU etc and still it comes on, only when the car is cold/warmish.
When the car is cold/or just warm it engages the air pump for 30 seconds then switches off (you can hear it) for the emissions and CAT heat up, now i doesnt even make a noise so i dont think the airpump is engaging - Is it known as the secondary air pump?
When the car is hot (probably above 75c or something coolant temp) and left for a short period of time (2-5mins) and the car started up the cel doesnt come because the ECU doesnt need to switch it on?, leave for 15+mins the car cools down and it needs to engage the airpump thus cel comes on again.
Other than this the car runs fine.
I have checked all the vac lines, airpump fuse etc, the only other thing I'm thinking airpump relay has gone, or even the airpump??
Thing is i dont even have a CAT and i'm thinking its no biggie ATM as it wont effect the car apart from emissions from cold.
Can i get access to the air pump or relay easily, cant be arsed taking the whole bumper off can i remove the left side of the underneath trim?
Plus it will likely rain at the weekend when i need to look at it
Thanks

Pump could have seized up - seemingly they do.
pm me if you need one as I have one I took off mine when the car had 3000 / 4000 miles on it - like new with both relays

Think I'm going to have remove the plastic splash guard underneath (passenger side) after work as weather is rubbish from tommorow afterwards - do you know if thats all i need to remove to provide easy access?.
I'm thinking its either the pump has melted/seized or relay has just 'gone'? - seems logical???
Thanks

Sure i know that Ron, its not really needed must weight about 3kgs
Anyhow I've been under the car, wiggled/unplugged connectors looked at relay and pump looks fine i think it was maybe replaced at somepoint for a TSB anyhow the fecker works now as it should!
I fail to believe its just a connection issue
