Hi I have had my 159 2.4 Ti for a couple of weeks and I love it. Whilst going through the service history, I noticed that it had been remapped. I contacted the garage that did the work, but they weren't sure what had been done, as they bring in a tuning company. My question is can I read the ECU too see what has been done, or is it a specialist job. Sorry if this queston has been asked before but I have searched and can't find a definative answer.:alien:

MES will tell you how many times it has been programmed, and at what mileage but not the details of the remap.

Diesel MAP normally concerns 3 items - DPF, EGR and extra power via fuel supply and turbo blow.
MES may tell about DPF&EGR status. You can also check it physically looking at EGR ( blanked or not ) and DPF ( cored or not ).
Extra power MAP never done normally with DPF&EGR stays unmapped.
Start from this. Rest is to be done by specialist.

Ok thanks for the info. Pardon my ignorance but what is MES? Firstly I will check to see if EGR has been blanked. Had a quick look earlier but could only see the what I presume is the gasket. The garage did say that the only remap would be EGR DPF and for better economy.

You can remap the car in such a way that the programming count and programming date are not changed. So it isn't necessarily a clear indicator. Best way would be to read the existing file and compare it to an original file.

I don't have the original file as it was done before I bought it. I really have no experiance working with ECU's Ok on the oily stuff. Will I be able to read the existing file with MES?

This forum is brilliant for information and knowledge. So glad I have gone back to Alfa, even though I did like my Subaru Legacy.:biglaugh:

NoNoNo... Special tools is needed normally used by mappers.
It is to expensive to have for single case.
Something like attached.

Might be easier to ask the garage who invoiced you to tell you which tuner they use? If it wasn't put on a rolling road (doesn't sound like it) it will be an off the shelf map probably, so you can probably just google them after you know who it is.

Contacted the garage and they informed me that Angel Tuning carried out the remap. Spoke to Paul at Angel's Troon who was very helpful, but he couldn't find my registration, so still in the dark. Paul also stated that the 2.4 JTD doesn't need the EGR to be blank off, which is different to the consensus on here, any thoughts?:confused

It doesn't NEED to be physically blanked, if turned off in the software. But, you are then reliant on the EGR valve itself to stay shut and not leak exhaust gas into the inlet manifold. For the sake of 4 bolts, I prefer to fit a blanking plate as well as switching it off in the software. Belts & braces.

Thanks for the information I will blank it off, at least I will able to see if it has been turned off.

Update the Egr has been blanked off so the map must have been EGR delete. I still have the issue of white/blue smoke on start up and rough running for a very short time. I have also noticed that the glowplug light only stays on for around 4 seconds. Have tried the ignition repeat trick does seem to reduce the smoke. The last service done in June, had 4 glows changed, would one faulty glowplug cause this problem? I have not checked which type of plugs have been fitted, as from reading on here there are 2 types. Once again I bow to your superior knowledge.

Faulty glow plug(s) if any, show you a message on dashboard.
Glow plug light ( work in fact ) duration depend upon ambient temperature.
Than hot it may not even be activated.

White/blue smoke is usually caused by oil being burned.

It might be worth taking one of the inlet pipes off and checking to see how much oil is in there. A small amount of oil is normal, but if you have loads of it you may have leaking turbo seals.

Roughness on startup could be slightly leaking swirl flaps (you'll notice dirt/oilyness on top of the inlet manifold if you look down), also there was a software update to cure cold start roughness and it makes a hell of a difference.
