how do you guys go about the fault with secondary air injection fault, air flow too low?

on 203 200k

Its the relay that burns out and keeps the pump running???

 

[Cole@MBS]

Just to add, its the same relay on the 220 model which controls the air-matic pump, that then burns out!! loads of cash due to a relay!!

nope sorry pal, was a momentary lapse, i thought you were psychic

ie a 203 200k, engine light on the dash, fault code; secondary air injection malfunction, air flow too low.

cant think of code at hand,

the valve is located at back of head, operated by vacuum,
had a few problems with one lately, all sorted now i hope,
was just wondering if you guys have experienced it,

it does work differently, on 113 its an electric pump is it not?

 

[Cole@MBS]

Check the small pipe under the engine ECU and the gubbings, seen them spilt and give the same fault code!!

Yes it is electric

 

[MB TECH WARRINGTON]

Yes it is electric

different system on the 111 engine, works via vacuum which opens valve and gives increased air flow into throttle housing,

I will read it up and see what I can make of it

first thing we checked, the filter below the valve was seriously blocked, changed this, all vacuum pipes are ok, erased fault,
after 1 week, car back with same fault.
had it in this week and hopefully now sorted, was just wondering if you guys have had this one and what you did to remedy it?

Still put money on that small valc pipe!!!

 

[MB TECH WARRINGTON]

Still put money on that small valc pipe!!!

vacuum was fine to the manifold, no leaks at all to any vac hoses to manifold,
if it comes back ill check but im pretty sure it wont now,

 

[Cole@MBS]

Caught me out twice before i found it, its not a vac pipe, its out of sight! i will try looking up on EPC tomorrow, cant see it on wis, let you know tomorrow mbtec!!
