The old flashing glow plug light symptom

[Oldvandriver]

I have a 2005 mk6 2l DI and twice I have had the glow plug light flashing recently,Both times I was pushing hard. So I floored the poor old girl to get on to the A3 without getting flattened, I noticed a bit of black smoke at max and the light came on, I turned the engine off in a few miles at destination. In a few minutes I started up again with absolutely no trouble and the light was gone, until about a fortnight later when the same thing happened. At no time did I feel any change in the engine, either sound or power (so no limp mode). When I put my useless wifi scanner on it I got a code PO 0235, So, what do I do first ? ( apart from not pushing it !) is this a major prob ? I'm kind of hoping that I can fix the smoking under pressure thing, RE MOT time !
PS why does this site come up as an unsafe website on my new I pad all the time when it's ok on this one ?.

I had this on my mk6 and it turned out to be the diesel filter clogged up, worth a try?

Re van is it tddi or tdci
Re unsafe site dont read any of bjt's comments you will never be able to think straight again

Or just don't look at the 'Non Transit Talk' section; most of the rest of it is quite safe

My van is,I suppose a Tddi, it's described as a DI in the etis info. I poked about a bit after I posted my question and found what I assume to be the MAP sensor at the end of what must be the intercooler, on top of the metal pipe in a very dark and sticky place under the radiator.

Oh and it's a new fuel filter(well a few months old) and the filter checker whatsit says its fine.

I'm kind of worried that if i just change the sensor I might push the ecu into instigating "limp mode". Anybody ?

Try changing the air filter too and clean the MAF sensor (carefuly -just use the special MAF sensor cleaner spray can).
