Hello,
I have a 207 VTi Petrol.
The engine fan runs immediately when the car starts and runs for about 5 minutes after the car is turned off.
I've connected a generic code reader, and it has 1 error - code P11AA
The last thing that was done was had the timing chain and tensioner replaced.

I've found this info:
Peugeot 207: hi have a 08 207 fault code P11AA and cooling

Would a BSI reset actual solve the problem?
It's probably the case that there is a software update for this car (it's probably never had one) but will that solve this issue? (I don't want to pay for it if it's not likley to be the problem.
Is it likely to be something else. Some posts are mentioning air leaks / pressure & sensors but I'm not totally understand what they're on about yet.

Thanks, Jon

could try it, but after a recent post it would seem that reseting/clearing it with pp2000/lexia would be my first stop.

have you cleared the code with your obd2 scanner?

Hi not sure if this could help
But I took my 1.4 207SW VTI
In for service and when it came
Back the fan would run continuously
Even on start up and would run for
Ages after pulling up.
Found they had been over generous
When topping oil up also even though
It looked it the oil filler cap was not seated
Properly resolved both SUCCESS JOB DONE.
Hope this helps Kev

I haven't yet.
I wasn't sure if I should keep it there, incase I needed to get it to a garage. I haven't got PP2000 and I was also wondering if that would provide more info.

Now this is one I've read about too....
I've been to it twice and I can't get the filler cap to go on any better than it is. I place it on the top and turn it a 1/4 turn clockwise, which seems to lock it in place. It seems fairly solid. Is there something I'm missing; e.g. do I have to push it down like one of those tops on medicine bottles?

Righty,
So I have just done the following:
1) Clear the error code - There was one Error Code P11AA and one Pending Error Code P11AA.
2) Done a BSI Reset, as described here BSI Reboot Process for Peugeot - United Kingdom | BBA Reman
3) Started it up. All seemed OK.
4) Drove to petrol station and gave it a gulp of fuel. This is about 2 minutes, on a in town A road.
5) Drove off again. Still OK
6) When drove between two junctions on the motorway (I'm going around in a big loop). This was about 2 to 3 minutes. Did most of it at 70.
7) As I came off the motorway I noticed the engine fan was on. The temp of the engine on the dashboard was about 90 degrees as I drove off. The temperature dropped to about 80 degrees as I drove off.
8) Drove back along the A round home. Every time I slowed down for a corner the temp want from 80 to 90 and the fan came on. As I drove off it dropped again.
9) As I got home fan came on again.
10) Turned engine off and fan was on for about 5 minutes until the temp dropped to about 70 degrees.

I'll point out now that I don't often drive this car so I'm not sure how much the temp changes; but that seems like a vary rapid change. It was going from 80 to 90 degrees in a small number of seconds.

I looked at the temp (I think) in the live stream of my reader and it matches the dashboard. See Reader Stream.jpg.
There was a pending error code in the DTC list; P11AA. See Pending.jpg(I have to be honest here, I don't understand what a pending code is. It implies it's a error that's about to happen.)
There aren't any error codes from the Auto Scan. See Code Scan.jpg

Anyone got any ideas?

Generic code readers aren't always able to read the ECU correctly, which means sometimes they miss out info which could be vital to the fault. Especially as some 207 engines use different codes to most generic OBD readers. If you can get the car on Diagbox or Planet, that should give you more insight into the fault.

I'd be tempted to look at the temp sensor, thermostat and coolant.

I've read before that this might be down to a software issue, and the ECU might need updating. If I find the link, i'll post it

Hi,
Hadn't seen the first link before.

From the first link:
>Reset adaptation helped P11AA error of the pressure sensor for
>now is ok. One mistake is a problem that the timing chain is
>pulled and the other probe damage the catalytic converter.
Ok, I don't really understand this one. What are they actually saying they did?
(Apologies if this is obvious but I'm not very much an amateur at this car stuff.)

From the second link:

>However, check first if the sensor is working as it should
>(by monitoring the live data using a diagnostics computer).
So my temperature gauge on the bash reads the same as the ETC.
on the live stream reader. Should I be looking something else as well?

>If that is operating normally, then you need to have the
>engine management software updated.

I'll check coolant level now.
Someone has suggested to take the grill off and cleaning the contacts on the fan. But that was on a 307.

It's not just the level of the coolant - it's the concentration/quality/strength of the coolant added to the water. If it's old coolant, it could need replacing.

The temp on the dash should match the temp on the reader. But if the thermostat is faulty, then it could be opening at a much lower temp than it should. Normally the stat will open at about 89deg.

Maybe other members who have this engine can confirm what's been said about the software update. It might be possible on Diagbox - I've never been asked to do it before, so I'm not sure if it is something that Diagbox or PP2000 can do, or if it's a job for the dealers.

Ok, that I can look into.

OK. I have the same temp on both. Which would fit with a sensor / ecu fault.

Maybe other members who have this engine can confirm what's been said about the software update. It might be possible on Diagbox - I've never been asked to do it before, so I'm not sure if it is something that Diagbox or PP2000 can do, or if it's a job for the dealers.
I think this might be a case of google is my friend. I'll come back on this one, if I find out. I'm happy to get a ECU update and / or buy PP2000 to do it myself (I'm happier with this option), if there's a good chance it'll work afterwards.

Ok,
bit more info.....
Looked at the coolant - seems OK.
Cleared the error codes again, even though there weren't any.
Took it for another spin, as described before. Didn't stop for fuel this time.
Didn't get the problem with the fan, but it was randomly miss-firing.
When I got back I checked the error codes again. There weren't any. There were two pending codes:
P11AA
P2178

(I've looked up what a pending code is now)

It's all a bit too random to be mechanical; the symptoms don't appear very consistent. I think you guys are right in that it needs connecting to PP2000. Reading on the internet it doesn't appera as if PP2000 can do a software update (if one is needed) unless I have access to the peugeot server, which is for dealers only. More than happy to be corrected on that.

Ok, bit of an update.....
It's been for a software update and now runs a lot smother.
Still intermittently lumpy, more if 3rd & 4th than the other gears.
If you change gear the lumpyness goes away.

It still has one error code "P11A - intake manifold pressure sensor. Fault could relate to air leak somewhere in the system, incorrect setting of the timing or fault with under bonnet fuse board."

The fan is still going ballistic when the car stops; for about 5 mins.

The guy who replaced the timing is adamant that the base timing is correct; and I have no reason to doubt him. he did mention there is the timing related to the cam / crank sensors. We have had issues with the cam / crank timing before. We haven't yet tried replacing the cam /crank sensors. Would that be worth trying?

If there's a problem with the fuse board, then from what I understand that could have migrated it's way to the ECU (as it's in the same box). Have I understood that correctly?

An air leak could be anywhere I guess.

Has anyone had any experience / seen this before and does the above sound about right?

Thanks, Jon

timing side would throw a code cam/crank/dephazer etc even on a standard obd2 reader.

thinking outside the box unplug your map sensor see if it goes into a pre set and see how it runs, not done this on a peugeot but have on other makes.

also remove sensor and check the tip to see if it has built up gunk.
