$170 might be pretty cheap in the grand scheme of things if that includes parts and labor.

The code from the scan will give you a problem, but not a part #. You need to know what part needs to be replaced/repaired so you can find out what it costs, and then get an idea of what is necessary to change it. Might be possible with typical tools, you might need a special tool.

If you can provide more information, we can probably provide better advice...
 
What's the code?
Contrary to popular misconception the OBD system doesn't necessarily tell you what part you need. Only where the trouble is.
For example my Jeep 4.7L has a P0303 code.
Which is a misfire on #3.
No. 3 cylinder isn't firing.
It could be an internet engine problem, bad spark plug, a bad coil (DIS), bad fuel injector, wiring to the coil or injector and probably a thing or two that have slipped my mind.
All in all $170 sounds reasonable to me.
You can Google the DTC (diagnostic trouble code).
It should tell you the issue and what the problem MAY be.
I have never heard of a "infiltration system"

This was my dad's quick fix:



Last Dodge Dakota I had, the check engine light came on. Took it to Advance Auto and they ran a scan and gave me a print out of the code.

Asked a new auto knowledgeable friend about it, he said it was the torque converter throwing a code. Said it must be a bad sensor because you wont need a check engine light when you have a torque converter problem.

I took the dash out and there was a tiny bulb that lite the CEL. I got some tweezers and removed the bulb.

All was fine.
 
Infiltration system? Is this the cabin filter? Maybe it takes 2 days to get the part. Chevy dealers here charge $100 for diagnostic before they'll touch the vehicle.

Here in Pa. We have emissions testing/annual inspection.
The emission test is done first. If there's a fault detected it throws a light.
Remove the bulb, you got rid of the light but the fault is still there.
A CEL stops the emissions test DRT.
Perhaps not an issue in your state.

A check engine light is only for the emissions as already stated. The only filtration items for the engine that would trip the light are: engine filter, fuel filter, gas tank charcoal filter. The $170 sounds about right for a dealer to replace it. Fuel filter will cause drivability problems, I would expect a lot higher cost for a dealer to replace, a lot of newer cars have a filter/pump assembly in the tank. The charcoal canister can cost several hundred dollars to diagnose and repair, failure is usualy the result of overfilling the gas tank.

Just some wild guesses based on very little data. The cabin filters wont give a CEL, just low/smelly air flow.
 
I'd guess air filter for the engine. Based on age of the car and a CEL.
With a code it could be narrowed down quickly.
Did the dealer give her a repair quote? That would spell out the issue and parts needed.
 
Does strike me that something got lost in translation, either between the OP and his girl or from the OP to here via his fingers.:)
 
Just a warning that a local auto parts store may clear the code without fixing it. That data is lost and now you wait for it to come back. And hope it doesn't throw a walk into you.
 
Many times the evac purge valve (I believe that is the name of it) can cause that problem. The part is about $35 bucks and is relatively easy to install if you have the aptitude. Depending on the model, sometimes they bury it in the rear of the engine compartment and it's a pain in the butt to access. Just put one in my wife's car and solved the issue with the check engine light but I scanned the car with a friend's Snap-on scan tool first so I knew it was probably the right part to replace.

So here is problem - there are also other parts of the evac system that can also cause a check engine light to stay on as well - even a bad gas tank cap will do that. Unless you just want to start replacing parts until you find it, you will need to scan the car's computer so you know where to start. If you don't have access to one then yea I suppose it's cheap enough to gamble & replace that part.

Just out of curiosity, isn't the car still under the warranty?
 
The check engine light isn't totally for emissions. I once had a CEL show up on a Suburban we owned. I read the code by a method not in use any longer and used a check list to figure out what it might be. That code had a long list of possible causes. Running down the list I found "fuel filter". A quick check of the maintenance log showed I'd been forgetful and changed the filter and cleared the code. That turned out to be the problem.

Infiltration = filtration?

BTW, they now generally bury fuel filters in the fuel tank. If that's the problem/fix, $170 is cheap.

Sadly $170 is pretty cheap for a dealership to fix anything these days. Labor is generally at least $100 per hour which may or may not include a separate diagnostic charge, and then you have parts which will be at full retail price.
