Technical Leak at heater matrix/pipe joint - HELP PLEASE!

Technical Leak at heater matrix/pipe joint - HELP PLEASE!
White smoke could be partially atomised fuel, or unburnt fuel. Might point at a heater plug issue or dirty injectors. Give it a dose of injector cleaner. (Redex, or similar, in the fuel tank.)
Recently another thread had issues with MAP sensor readings. I think that turned out to be sticky boost regulator, so overboosting. MAP is only reporting what it senses, and overboost will give it a reading above parameters. Might be worth checking the boost valve on the turbo is operating freely. More cleaning to do.

Thanks everyone.
Still got problems I'm afraid. I've been checking the voltages from the MAP and MAF sensors. The "good" news is that it looks like they are both sending out valid voltages of around 2 volts at idle on the correct wires (I think almost anything between 0 and 5 is acceptable, with higher values indicating the engine working harder). Those voltages vary linearly as the engine is revved up and then allow to return to idle. So it looks like there is summat else causing the P0106 error code, unless those voltages are outwith acceptable parameters.
My wife is adamant that the EM Light went off whilst I was poking my multimeter in the back of the MAP ground pin with the engine running and whilst the MAF was disconnected! I am damned if I can replicate it, or figure out if that might be a clue.
Portland Bill - The white smoke is immediately after a cold start, and then dissipates within a minute, or so, and it is gone until the next cold start. Would that match your injector theory? Anyway, I'll have some Redex in there shortly and will see how that goes. If no joy with that, I'll have a look at the boost regulator and boost valve.
Does anyone know if the light will simply go off once it is happy, or will it stick until it is told to go away?

Thanks Steve.
Macduff isn't too handy from Westhill.
I'll keep poking and will see how I get on. I've downloaded the MultiECUScan free thing, but am having problems getting my cheapo Amazon Bluetooth EM327 ODB dongle to work with it on my laptop - This dongle seems to work OK with Torque Pro on my Android tablet, but it doesn't have the functionality of the MultiECUScan hoodjie.
Anyway, it looks like the MAP and MAF sensors are probably OK and it is something related that is throwing up the P0106 code.
Cheers.

White smoke probably more pointing to heater plug failure. Once warm, fuel atomises and burns ok.
Light should extinguish after 3-5 normal starts without issues, but code may still be stored.
To try to get MES to work with your ELM, have a look at this thread, specifically my post, post number #5 . Try that procedure, hopefully that will work. Sadly, MES forgets the settings when you close it, so you have to reset every time.

Developments.......
My cleaning of the MAP and MAF sensors and leaving the battery disconnected for a few hours seems to have cured the white exhaust smoke at cold startup - I suspect it was cleaning the MAP sensor that actually did it. I thought it was better yesterday, but it really wasn't that cold when I started the car up, so I wasn't convinced. However, this morning it was so cold that I had to scrape the windows and there was not a wisp of white smoke more than one would normally expect. Every day last week, it was like my Panda was trying to reverse through the "Stars in their Eyes" doorway to take Matthew out! So this is a very noticeable improvement and I hope that will be that.
However, there is still an EM light on the dash. I have just filled it up and have shoved in some diesel Redex, so will see if that blasts any crap out. If the light persists, perhaps the white smoke was a red herring and an unfortunate coincidence.
I'll let you know what happens.
Ta Portland_Bill. I'll have a look at that link when I get home and will see if I can get the MES to work with my cheapo BT EM327 dongle.

Further developments folks.................
When I started my Panda up to come home tonight, the EM light came on as part of the starting procedure................. and then it went OFF!
It's had a couple of stops on the way home, and the EM light has extinguished after starting both times.
I find it hard to believe that just 6 miles with Redex in the tank would have had much effect (In fact, I doubt it has got quite as far as the cylinders yet!) so it looks like the light was just being a bit reluctant to clear after the MAP sensor had been cleaned - or it might possibly have been the MAF sensor, but I don't think so.
I'll keep an eye on it and will have a dabble with my dongle and MultiECUScan shortly.

I can now speak to my BT dongle (Ta Portland_Bill) but can't get it to speak to my Panda ECU. I get an error about the EM327 version. I am aware there is a resistor that can be chopped out that might get things to work, but I would virtually have to destroy the dongle to get at it. I'll maybe buy myself a USB one to use with MES and pass on my BT dongle to needy friend.
In the meantime, further poking at Torque Pro (Free) on my Android tablet allowed me to clear the error code and things seem to have returned to normal. Let's hope that things stay that way.
