A6 2.5TDI Smoking + ultrasonically cleaning injectors
It doesn't do it massive amounts (not that I can see in the mirror from the
driver's seat) but a mate of mine has said that it smokes quite a bit, and
that it can be thick and black (yup, it's a diesel!).
Obviously it's the sort of thing you notice more at night than in daylight,
but this morning when leaving for work (engine had only been running a
couple of minutes up to this point btw) pulling away not particularly
quickly resulted in not particularly thick (but still noticeable) smoke in
the car behind's headlights. Obviously darkness and headlights do tend to
emphasise any smoke coming out of any car's exhaust though.
My question is this - does my engine (5-cylinder 140bhp 2.5TDI) have a MAF
sensor, and is this easy enough to take out and clean (should this be
neccessary), and if that's all ok, how much should I expect to have to pay
to get the injectors ultrasonically cleaned.
And is there much variation on the quality of ultrasonic cleaning services
available (I don't want some cowboys ing them up) or is it a
straightforward job that the machine takes care of with not much chance of
anything going wrong?
Btw, the car has just short of 127k on the clock, and has been regularly
serviced all its life (every 10k up to 50k at audi main delaer, then every
6k up to 94k with a new air filter and fuel filter every time, then at 105k,
114k, 125k, with one new air filter at 114k and a new fuel filter at 125k).
So I wouldn't say it's been neglected, though I have worried a little about
the time I've left it between oil changes (though it's been largely motorway
use) and the mileage the laster air filter and fuel filter did before
changing (20k and 30k respectively). Am I worrying about nothing on these
points? Is it the MAF sensor that needs cleaning, or is it time for
injector overhaul?

114k, 125k, with one new air filter at 114k and a new fuel filter at 125k).

Not really.
If it has failed, which I doubt because you have said nothing about a
drastic power loss, then it is probable that you will have to fit a
new one.

Before you go to any expense, first try a can of really effective
injector cleaner like Forte or Millers. Equally effective, and
cheaper, is a litre of ATF [automatic transmission fluid] for every 20
gallons of diesel in the tank. This is only needed once [a year
perhaps] and, in the case of ATF, will take the consumption of a
tankfull or two to work, but work it will.
Give it a go and report back after a thousand miles or so. You have
nothing to lose.

No drastic power loss. It's performing as it should. Economy isn't
terrible either, but probably a good 5mpg down from what it should be.

I think I tried some of that sort of stuff (not ATF) before - didn't notice
any significant changes. I've pondered the idea of putting it in a much
higher concentration than one bottle per tank (similar to redex direct into
the cylinders) but I'm worried about buggering something up (read the below
after a bit of googling):
"I had a vague thought about ATF in the back of my mind somewhere, I have
previously heard of someone using it neat, dribbled into the intake of a
running petrol engine as an upper cylinder valve cleaner but realised this
might result in a bent conrod or similar if attempted on a diesel, not that
the intake ports are accessible anyway. I hadn't heard of it being used
diluted in the fuel though and certainly didn't think it could take water
with it. I no longer run a car with an automatic gearbox, so that is a good
way of using up those couple of cans of ATF in my garage...I'd been
wondering what to use them for."

I'm a bit worried about ATF - it won't have a snake oil effect, will it? If
it was significantly more effective than the injector cleaner stuff then I
might be tempted, but I'm a scaredycat, so I might spend a few more quid and
get the "proper" stuff.

But you need stuff that does actually work. I can vouch for the Fore
and for ATF, but I used the ATF at two litres in twenty gallons. The
effect of the ATF actually lasts a good 12 months in the engine it is
applied to. It even gets rid of white smoke at start-up if this is a
condition brought on by age and use rather than being like that from
the factory new.

The point about snake oil is that it has *no* effect. Certainly ATF
will not harm your car and will provide the diesel with better
lubricity if nothing else.

A lot of the "proper" stuff is just snake oil. Or just oil. ATF on the
other hand is very good, high detergent oil.

No white smoke on start-up. Well, not that I've noticed anyway. Exhaust
points down, and I'm never in a position to see it when I'm starting the
engine!

I thought the point about snake oil is that it lingers in the system,
potentially causing future blockages??

Cool, that puts my mind at ease. I want it to have a really decent effect,
so I'd rather put more in and have more smoke in the short term, but a
longer lasting effect, rather than it just having a gradual effect - by tank
takes about 78 litres at most (so not quite 20 gallons) - would 2 litres in
a whole tank be too much (is there any potential damage it could do) or
should it be ok?
Also, you say you've tried it - have you tried on VAG TDI engines before?

Out of interest, I have an ultrasonic cleaner - what solvent do these
