Hi, I'm new here and have two 206's one being 1.4 hdi lx and the other a 1.6 hdi gti. I'm just about to buy a diagbox as I've misplaced the one and only key to the 1.4 and also intend to use the diagbox to remap my 1.6. The car was remapped with EGR, DPF and Cat delete before I bought it and I believe a poor remap is the cause of the car going into limp usually around 3 days after resetting the codes which usually only shows a heater plugs code which is nothing to do with the car going into limpmode. I'm hoping that someone here can send me the remap file to successfully delete the above or even advise me can this be done with the diagbox. Any help would be greatly appreciated. - Mark

Neither Diagbox or PP2000 can remap an ecu. For that you will need a galleto or similar device. Diagbox can read the fault codes, live data and allow you to change any parameters that Peugeot have made accessible like cruise control programming keys or adding a cd changer but a remap is not possible with the diagnostic kit.

If the DPF and EGR have been deleted correctly, then they shouldn't be the absolute cause of the faults. Has the EGR been blanked and DPF removed?

Many thanks Storeman, what is a galleto and how much are they, I have found the key typically after ordering a replacement blank along with id46 so won't need the diagbox for that reason, will the galleto remap the car without the aid of a diagbox? Jimmymarsbar, thanks to you also. I believe the Cat and DPF look like they're present but the gubbings have been surgically removed and yes the EGR has been blanked, by who with what skill level I don't know.

A Galletto is a device used to extract the map file from the ECU. Another device is a KWP2000 - the galletto is said to work better.

You can't use them to remap, they just read and upload files.

WinOls is often used to write maps, as it's free. But it can brick the ECU according to reports.

If it's a siemens ECU, the unit may need to be removed to remap.

If the DPF has been deleted, but the actual filter remains intact (including the filter medium), you could be getting a build up of soot in the filter, as the car won't be regenerating the filter. It could result in back pressure into the turbo, which isn't great.

If you're confident that it's all been removed, then you should be ok, it's just sometimes better to make sure.

Thanks again Jimmy, it's a Magnetti ECU. Would this build up and turbo back pressure allow the car to drive fine for 3 days? It's been doing this since January, I've had the codes cleared around 20 times and each time I get around 3 days out of limp mode. On one occasion and one only day theee arrived and as expected the car went into limp mode but surprisingly the car came out of limp mode without the aid of the snap-on diagnostics again giving me another 3 days of limp mode free driving. I'll be removing the DPF to check its contents. If the gubbings are stil inside can I physically remove them or do I need to get a replacement section? Thanks in advance.

you can bore a hole right through with the right equipment, this gives a nice clear passage for the exhaust.

It'd be worth getting the car on planet, rather than snap on, as only PP2000 and diagbox have the capability to fully interrogate the ECU. See what codes are showing as intermittent, this could be the cause of the on/off EML and limp mode.

Live data whilst in limp mode will help identify the problem too

Thanks all for the advice, windy, I'm unable to pm u as I'm new

Hi, I have a problem with my 206 that I think has been caused by a poor remap to delete the EGR, DPF and Cat, the car drives fine for three days after having it reset with a snap-on diagnostic but then goes into limp mode until I reset the codes again. Im in the process of buying a diagbox as I have another pug of which I have lost the key and I'm hoping to be able to reprogram my ECU with it in an attempt to sort the limp mode problem. You seem in the know as to whether this is possible with my car. Your advice would be greatly appreciated - Mark

No you cannot reprogram with diagbox/planet you will need a proper flashing tool like a galletto or MPS. What are the codes which are logged

Hi and thank all for the info, windy, I'm unable to pm u as I'm new here but here are the codes - p0069 - turbo pressure (downstream of heat exchanger) inconsistent with atmospheric pressure,
P3008 - flow meter signal air flow too high temporary fault,
P0299 - turbo pressure regulation turbo pressure measured too low, and P1351 preheating relay circuit relay supplied and plugs never supplied.
The car is running on a BMW 3 bar map sensor at the location which I have to change with the standard one so the first three fault codes are because of this, with the standard map sensor the only code that shows up is the last one which is nothing to do with the car going into limp mode but when the codes are cleared the car will run for around 3 days just fine. I maybe changing the car this week so may not bother any more, if I keep the car I will be checking to see that the dpf has been surgically removed or whether it's stil present. Thanks in advance - Mark

Clearing the codes does nothing except - clear the codes and basically tells the ecu the faults have been repaired so the ecu no longer tries to protect the system. You need to repair the problem. Keep clearing the faults and carrying on could result in the issues causing further damage resulting in a very expensive repair.

A complete list of the errors along with some live data when it's in limp mode would go a long way to narrowing down the cause.

When the 3 bar sensor was fitted was the ecu remapped with the new MAP offset and calibration maps as if its on standard settings the boost level values seen by the ECU will be wrong and therefore airflow/boost values will inconsistent.

This will log a pending and then permanent fault which could be why it takes some time before light comes on after being reset

Unless you have fitted a larger turbo you will be hard pushed on standard setup to need a 3 bar sensor if you are getting over boost or similar faults its likely to be a poor map and a missed boost level limiter
