All hail the genuine MAF, it's like a new Roo

There is one other thing to take in to consideration the mechanic who ordered your MAF could have order the MAF for the MY08 Forester part number 22680AA310 not the MAF for the MY09 part number 22680AA380.

Taking in to consideration what all three mechanics have done, the error codes still started after the new MAF was installed and not while the temporary MAF was in your vehicle. By process of elimination if you can try having the temporary MAF put back in for testing purposes and if there are no codes generated problem solved.

Good luck

Just did a quick check: it is 22680AA380 for a Forester that is registered as 2008 but VIN indicates 2009 and manufacture in the month of May.

Still the right part?

Mine is registered Qld 28th October 2008 Manufactured August 2008 , VIN model year 2009(MY09) and MAF part number is 22680AA380 (Physically confirmed with my own eyes)

The official release of the 3rd Gen Forester SH MY09 in Australia was March 2008.

Good link to another genuine parts supplier. Prices are still half of what the stealers are offering us here in Oz.

Wish my problem was this easy to solve. Maybe my MAF is defective at certain operating ranges. Maybe I should get another one and see what gives as I'm reaching the limit of my patience with this...

OK, thanks, so I've got the correct part.

Ouch!
Well, went to the dealer today for my 62.5k service. I asked the service desk person for a DPF ash readout from the vehicle. Once I had explained to him what it was and how it was obtained (yes, that's right), I almost had my head chewed off for asking for something extra. It was scribbled down on the service sheet in haste and with bad grace.
Even more lovely, this particular gentleman dropped me off (courtesy drop-off) at my workplace. Not a word was said on the trip or when I got there (eg not even "Have a nice day"). I did thank him for the lift, though :-)

Thinking, thinking...
I stewed on it for a while at work... then decided to ring the dealership and, lo and behold, the service manager picked up the phone.

Hello?? Am I in heaven??? What a difference!
The service manager was affable, knowledgeable and willing to talk honestly about the product. I mentioned to him my experience of the morning... and he just got on with it. Asked me what I wanted (DPF Ash readout). Hmmm, don't know that one...but I'll find out for you (honesty, interest, responsive/active)! I explained it's just a readout parameter off the diagnostics computer, he said that sounded reasonable and would find it out for me. I also mentioned my interest in "what happens when its full?" and whether a code would trip at 80%, 100%, etc. He said he didn't know, but importantly, he was aware of DPFs and what they do (just not the codes). I explained a code would trip when full, but asked what level it may trip at. He was unsure what level (honesty again!) but would find out from Subaru head office for me (action, again!)

At this point, I was beginning to wonder whether I was on the same planet...after all, I was on the phone and perhaps I had the wrong number!

Outcomes
The upshot? When I retrieved my vehicle later I had (apart from the service):

a) readout of DPF soot level (see my next post for level/km details)
b) confirmation that it will trip the code at 100% soot level (he'd found out from head office AND talked to his technician (activity! communication!!!)
c) He was also quite interested in the issue, what parameters could be obtained, when the DPF may fill up and perhaps what soot levels other vehicles may be at (he was going to have a look)
c) further questions revealed more of his knowledge:
...1) DPFs are harmed by mistaken filling with petrol (replacement required) and
...2) he was also willing to admit he had not experienced driving during a DPF regen
...3) he was aware of the revised shift points (mentioned he was glad I had the sheet and aware that they made a difference)
...4) mentioning a warning light to indicate DPF regen would be nice, he stated that the Aussie engineers had already mentioned this to Japan, and he thought the Japanese were reasonably good listeners so we may see something in the future.
...5) he also thought the auto in the pipeline would mate well to the diesel (Outback only to begin with...when the auto arrives) and perhaps help reduce further various issues

All up, an unpleasant experience to begin with was turned into a informative, successful and pleasant one due to the enthusiasm of the service manager.

Assuming linearity, 24% at 62.5k kms gives a theoretical ~260k kms before 100% ash level error code (apparently 100%- from Subaru service manager who contacted head office).

I am beginning to feel like a ping pong ball.
Latest non-developments are:

Took car to diagnostician on recommendation of my mechanic who double checked ( supposedly) Wippel's super duper Subaru scanner diagnosis that the MAP is defective.

Diagnostician checks MAP. With scanner. I assume. He asks me to ask my mech to give him the vacuum pressure readings. Huh? Isn't this a diagnostic procedure so why not do it himself. Me being an idiot, call my mechanic to give diagnostician the vacuum readings. My mechanic is a bit confused but says that he will have to take those readings since he doesn't have them. So I book car in again.

So far no payments for this farce.

For the sake of my entertainment during my lunch hour, I ring wonderful Wippels and ask them if they normally just go by their scanner readings. They say yes, that is Subaru recommended procedure. So, I ask, you want me to fork out $$$ for a new MAP and if it turns out not to be clearing the error, you just continue making me buy more sensors, is that correct? No actual physical testing of the sensor? Yes, they said. I told them I was not impressed by this approach.

I rang Subaru head office in Sydney and explained my experiences with their dealerships in Toowoomba and Ipswich. Not sure and do not care if they follow it up. I expect nothing will change when it comes to car mechanics and dealerships.

The only tiny bright spark I had today was from the Subaru dealer in Warwick. I asked them if they had a spare MAP that I could try out to confirm that my MAP is in fact defective. They looked around and said sorry they had none, not even the same model in the workshop at the moment. They suggested Wippels. I told them that Wippels do not work like that. He was very surprised and apologetic that they could not help.

Now, I"m waiting to get the real check with vacuum pump to be done by two separate mechanics on Wednesday. This is utterly unreal. Where are competent mechanics that will do the work as requested? Oh, yes, Boxer Service. Well, maybe, maybe not. I won't have it checked by them til the 22nd November so in the meantime I'm trying hard to get some hard and fast answers on whether the MAP is working or not. How difficult is this? VERY.

What the heck does this mean? My little scanner gives exactly those readings:
29KPa when engine is idling and around 99 -100 KPa when engine key ON.

A new ECM??

Have to add what I cut off from the top of the image. It says if I get the listed readings then replace ECM. If I don't get those readings then replace the MAP.

One more thing: all three mechanics I've had dealings with so far have never heard about OBD II drive cycles and how it works. Very confidence inspiring, isn't it?

If the problem has not been fixed by the time you see either Darren, Andrew or Belinda at Boxer Service , please make sure you tell them the history of the MAF Temporary sensor not causing the error code and then after the new MAF sensor was installed the error code began, this information will be vital for them to diagnose the problem.

Be prepared that Boxer Service will use the Subaru Select Monitor to help diagnose the fault.

If you are not happy with Boxer Service you can always travel 1 to 1.5km down the road towards Strathpine where Torque Subaru live.

Your current mechanics are not helping you with their performance or lack there of

Good Luck

I think it's worth going to the non-official Subaru specialist. I think it's more likely they have spare parts (2nd hand) lying around to test with.

Given your MAP is reading reasonably at both low (29kPa) and high (100kPa) pressure regimes, it's unlikely to be the MAP.

Without pulling a known vacuum on it with a Mitivac or such, you'd never be sure.
