OBD scanner problems

[Cfiver]

Hi All.

I hope somebody can help me with some advice regarding OBD scanners. I purchased a cheap Ebay version with MPPS software a few days go and spent hours actually getting it to work on a laptop. When I finally succeeded and plugged it in to the car I got the reading as per the attached photo and could go no further. I checked with the vendor to verify that my car would be catered for and he stated that it was but now I'm not sure. I am a novice as far as this is concerned and it looks like being a steep learning curve!

Car is 2004 C5 Mk11 2.2HDI auto Exclusive and ECU is EDC 15C2 K line.

Do you have any more photos showing what happen when you select EDC 15C2 K line?

Just to check, you do know that MPPS is a software for ECU/tuning flashing? Or, do you actually know what you are doing to the car?

Hi Paul.

No more photo's I'm afraid. Could not get any further as ECU not recognised.

Yes, I do know what it is. I wanted to start with showing any faults that may be present. I don't intend to alter anything at this stage.

Personally, unless it is one of the "Pro" ones and thus mega $$$ I would only interface with a PSA car via Diabox/Lexia

MPPS is not an obd diagnostic system. It cannot display or clear fault codes. It is usually used to remap the ecu generally with the intention of more power. It can also be used to transfer firmware from one ecu to another. I use a different but similar system if I ever need to replace a faulty ecu. I can clone the original ecu so that the replacement is plug and play, and works with the existing immobiliser, body computer, dash etc depending on which units are coded together.
To go remapping there are two options.
Option 1 is to download a flash file and hope it does what's promised when loaded into the ecu.
Option 2 is to create a custom file and load it. Impossible for most of us and slightly less difficult for those who have a detailed knowledge of the fueling and other parameters of a given engine and also have the required expertise to create the 3d cartographic maps. A dyno to test the results is also handy.
If you want to diagnose your car there are several systems that work very well. If you only work on one make then the manufacturer specific one is always the best. For Citroen that is lexia / diagbox.

Many thanks BX for this information. When I purchased the MPPS system the Ebay listing stated that it would read as well as write! Have seen a Lexia/diagbox for around a hundred quid so will get hold of one of them.

There are a number of members who own Lexia/Diagbox equipment and many have found that buying from Easydiagnostics is recommended.

A list of members who offer diagnostics using their Lexias here and a mixed bag of Lexia info here.

Thanks Steve. Easydiagnostics is the one I'm looking at.

Mention that you are a forum member and they will usually give a discount - even if it is only free postage.

Well, duh, it does that, but it's not a car diagnostic package, but what BX explained ... that's why initially asked you if you know what you're doing to the car (or, what it is you want to do) ... and you confirmed ...
