Want to get rid of secondary air pump, so I can put IC reservoir in its place, do I need star to get rid of cel on dash?

 

Without the pump you may not pass a pollution check if it is done when the engine is cold, this really will not be a problem as the car should be hot when tested.
The light must not come on as that would be an immediate fail.
But you know all this.
I am talking about Canada, it may apply to many States as well.

 

I believe u can shut the cel light when u remove the pump, through star, I'm just trying to confirm that.

 

Question is, will a code set when repeated signals (cold start/hot run/stop cycles) that the pollution control isn't working correctly when cold? A test of this would be to pull its plug for a few cold start/hot run cycles, and see if any (MIL/lamp) or code(s) sets. Sometimes, the lamp waits a preset number of 'pending' conditions before a code sets off the dash lamp. Not familiar with the symptoms of the air pump setting a lamp or codes on our XF's. On my 02 Camaro, if the air pump goes a 'Check Engine' lamp hits the dash (this I know because I had to then buy one and replace the bad one). If it does set a lamp off, and a code, it will show up and fail emissions testing. Remember also that if you 'clear' codes before an inspection, it resets all the emission monitors until the predetermined 'drive cycles' reset those monitors. A monitor that is not reset after a code clear, will also fail in those states that have that as test criteria. Also, no idea what else might be 'trimmed or readjusted' in engines fuel/air ratios to (possibly) compensate for the pump not running.

The secondary air pump it's a issue in this car apparently I have this issue check engine light on instead of replacing it my friend works an q shop it suggested to have it tune to eliminate cats and the air pump itself this might be a option I didn't do it yet so I'm waiting to add some mods to tune it good luck

 

Hi

You can turn off the Air Pump, EGR System and Rear Oxygen Sensors if you want to. The codes can be changed using DAS/Xentry. You wont get any error codes or CEL, but you wont meet any pollution standards.

 

I can confirm that this works on an SLK32. You need to have a StarDas with "developer kit".

(on the slk32 and the SL55 at least) after you have shut the secondary air off (change coding at location "0178"), you can remove the air pump (physically and/or electrically) with no check engine light and NO "un-set" readiness monitor.

similarly, you can turn off the rear oxygen sensors (using StarDas with "devoper kit "to change coding at location "0182"). On the SLK32, the result is no check engine light and no "un-set" readiness monitor.On the M113k cars that I have messed with (SL55, E55) you get no check engine light HOWEVER, you DO get an "un-set" readiness monitor (for o2 sensor heaters). (worth noting, conventional wisdom has you leave the rear o2s plugged into their harnesses even though uninstalled from actual exhaust).

hope that helps,
Chris

 

Ok it can be done, pollution test here is just to see if any codes come up cel, it's not tail pipe test.
