Let's look at this from another angle:
If you lent your car to a friend and he had a problem with it, and he said to you later: "About 50 miles left and the oil warning light came on with the letters HI... Around 30 miles later the revs started limiting I think but I was only 20 miles from home. I was worried enough to call into MB Carlisle for some technical advice but decided to drive home anyway. 150 yards from home an the car is fine then boom the revs go through the roof and I get a huge amount of smoke from the engine before I switch it off"
What would you think about your friend?
A - it must be my fault, my friend did nothing wrong, I'll just put my hand in my pocket and have it fixed
or
B - he's a complete doughnut?
Of course this is a hypothetical situation unrelated to yours...

It's a bit different as the car had just been sold so should have been ready for the drive. The O-p went to MB Carlisle for advice.
A car just sold should be able to complete a 150 mile journey, otherwise it's not of merchantable quality or fit for purpose..

Moylesey,
You continued driving the car for 50 miles after the oil light came on?
I'm afraid you are the author of your own tragedy. Trader or not, you were responsible after you decided to continue driving once alerted something was amiss.
It's just common sense.

OK, so if I buy a car and it picks up a puncture on the way home, I'm OK to continue driving it on a flat tyre because "A car just sold should be able to complete a 150 mile journey"?
What happens at mile 151?
At what point (mile 152?) does common sense have to be used?
Just wondering where "If they won't play, Take it to Trading Standards" and "Not really fair on the trader to ignore a warning message, keep driving then expect him to fit the bill...." - "so dont tell him" ends and common sense begins

The trader has been very decent so far about the whole thing and I realise that I may have been a factor having chosen to drive on in the car with too much oil in it. I was however on the road from Scotch Corner to Carlisle and any of you who know it will know why pulling over and getting help is not as easy as it sounds. Hopefully I've just got oil in the air intake and it can be repaired quickly and cheaply and if this is possible I won't be chasing the trader for anything. In fairness to myself I know nothing about A Classes or their warning systems and couldn't find any reference in the manual to a Hi warning message. I had only been in the car for and hour having driven over 10 miles on test and about forty on the A1M can't think why if there was too much oil that the message didn't pop up straight away.

yes, but tough lesson for the trader to learn about oil levels, after all, he is the `expert` in all this

I feel for your situation my heart goes out to you but in truth as soon as a warning pop's up it ought to be checked especially in a new car / environment this is wise and part of the learning curve. But! 20/20 hindsight is a wonderful thing as we all know.
Now, as for the problem emerging, it is due to the time it takes as the oil starts to heat up and aerate in the engine as you drive, it gets picked up and thrown about, so more and more make's its way into the induction system, without the benefit of an oil-trap (something more and more people fit to high pressure diesel engines to sole this and a few other sludge issues that occur)
It should, if everything is just as you describe, be a simple case of draining cleaning and letting the engine settle out in it's own manner until it's happy again. This could be a messy old job and not a massively expensive one at that.
Best of luck and I hope when it is returned to you you enjoy your A-class

Could Prove Expensive?
Bad news is that if the MAF is badly contaminated and requires replacement its expensive as its combined with the engine ECU. http://www.aclassinfo.co.uk/mypage.38.htmhttp://www.aclassinfo.co.uk/mypage.38.htm

It shouldn't contaminate the MAF as the breather enters the intake further downstream.
Car is still there - went back to it this morning and turned the key and there was just a flat sounding farty turnover and no ignition. I'm trying to get a tow back home and will then look at getting some oil out of it and having a look at the air intake.
Can't find a mechanic who will come out - anyone would think it was a bank holiday weekend...
Thanks for all the positive advice although it would seem there are still some on here that have never made a mistake and call those of us who have been unfortunate enough to own up when we do.
Now where's my doughnut...

If it's close to home (150yds?), can't you get friends or neighbours to tow it with a rope, or even push it if fairly level?
Edit: If you say where you are there may be a member or two willing to help you back with it if there's a drink chilling in the fridge when the job is done!!

Isn't Mobilo still valid on the car - when was it last serviced at an MB dealership?

Actually did the same as you once, ignored a warning light kept on driving and blew the headgasket. Cost me a fortune to put right, my fault completly though
Tought me a hard lesson.

If it revved high then find out from the diagnostics (Anyone confirm the A Class shows peak revs?)
Don't try and start it, could could have a cylinder with lots of oil in it.
Don't tow it or anything in gear.
I used to do breather work for a few years and the first thing you want to do is this....
Check the oil level on a flat surface after it has spent all night draining down. If it's very low it can indicate if it ingested lots of oil or only a small amount.
Remove the air filter and inlet pipework to see for any signs of oil, you would see a small pool of it if it was running on its own oil, or trying to as it takes a fair amount to get going.
Remove the injectors and either check down them with a boreascope to see if any oil is visible and if so then somehow disable the fuel pump and then crank the engine over. If you can't be sure that fuel wont inject then DO NOT ATTEMPT TO DO IT AT ALL. An injector will cut your finger off if it fires right next to you, i've seen it chop through 10 gauge steel plate.

Does an A170 cdi have a turbo?

Yes. All CDi have turbos.
You haven't been able to buy a normally aspirated mercedes since 1997.

The turbo oil seals could have been drawing in engine oil.
Unmetered oil (fuel) being pumped into the turbo and then entering the engine under turbo boost = no control over engine speed,the more oil is pumped in,the higher the engine will rev,and so on - the sky-high revs the OP experienced before the engine went `boom`.
Which may explain the oil level,`HI` warning light;the previous owner or the supplying dealer knew of the high oil consumption fault but tried to cover it up (temporarily) by overfilling the engine?
Lets hope the `boom` isn`t as serious as a `boom` suggests.....

Mmm. The worst thing about this is not being able to get a diagnosis due to the bank holiday. No matter what the damage (I think!) I'd rather just know. Turned the ignition this afternoon very briefly after draining some oil and cleaning up and got a puff of smoke from the bottom of the engine so I'm just leaving it now.
The engine oil in the dipstick and filler cap is black and there are no signs of water in there and no visible signs of damage in the engine compartment but the engine just wheezed before the puff of smoke appeared - time to leave it and let the professionals take a look and hope it's something relative cheap to fix.
Not hopeful though...
