I was going about 85 mph last night on the A1 (m) and the car shuddered a bit, then the Engine Warning Light Came on. I pulled over but it was running fine and the light went off. it happened a further three times.
Has this happened to anyone because ive not even had the car two months yet.....and i'm getting slighlty pissed off with it now.

Yes, I've had just the same symptoms. It turned out to be the idle control stepper motor in my case, although a faulty air mass meter can have a similar effect. It's very disconcerting when you're driving along and the engine suddenly seems to stall and drag and then starts running again. Try seeing if you can make it happen when you pull up at a junction (when you slow up to stop the idle control motor takes over).
When it happened to my car (mine's the 1.0l 12v) the dealer diagnosed it with a tech 2 with the engine running, NB the ecu didn't have any fault codes saved (so a paperclip test or a passive tech 2 readout didn't show any stored fault codes) but with the tech2 attached and monitoring the engine in real time while it was running a series of error codes were being displayed on the tech 2 from the idle control motor. You can really only get this diagnosed at a dealer unless you can find someone with a tech 2.
Be aware that you'll probably pay a rip-off price if the dealer does this for you, they charged me 40 quid for about 5 minutes work in total. The tech 2 is a piece of diagnostic equipment that looks like a large multimeter that they plug into your diags socket.
Dealer wanted 70 quid for a new stepper motor and vat on top of that, so I went to the scrappy and got one for a tenner off another car. If you do that try and get one off a fairly recent car as they do wear out, the dealer told me he's sold loads of these bosch stepper motors for corsas.
The motor I'm talking about sits on the side of the throttle body (at least on the x10xe and x12xe engines) and actuates the throttle when the engine is idling. It's real easy to fix, pull out the wiring loom plug, unscrew the motor from the side of the throttle body (you'l l have to take the airbox off the top first), screw new motor on and plug back into loom. I replaced mine with one from a 1.2 engine and it works fine, you need to check that the bosch part number which is stamped on the side of the motor matches the one from your engine if you get one from the scrappy. The 1.0 and 1.2 engines both use the same motor (at least for corsa-b, don't know about corsa-c, my guess is they'll be the same)
In my case I also cleaned all the connectors on the wiring loom to the idle control and air mass meter (they don't use gold plated contacts (it's crap quality) so inevitably you get oxide and dirt build up over time which means that you'll get a voltage drop in the signal or potentially intermittant contact problems). Clean the connector pins with cotton buds and isopropyl alcohol, usually get's some black oxide muck off the pins if the car's done a few miles.

Another thing I just remembered, you might just have a dirty air mass meter sensor. The "hot film" air mass meter sits inline in the airpipe between the air filter box and the throttle body air box, inside the cylindrical housing is a square of platinum (I believe) film which is heated and acts as a gas flow rate meter to measure the amount of air going into your engine. You can clean this by giving it a spray of carb cleaner. If you've got an oiled cotton induction kit fitted this can quite commonly mess up the air mass filter as oil evaporating from the induction kit material deposits on the platinum film (the people who sell the induction kits don't tell you that!). Whatever you do don't try to clean it with a cloth any grease you get on it will mess it up, carb cleaner or isopropanolol spray is about the only chance of cleaning it. Again my remarks above about cleaning the contacts from the air mass meter to the wiring loom apply. Remember a new air mass meter is going to cost you about 300 quid (it's a complete rip-off) so I'd advise trying a different idle control motor first, it's more likely to be the motor anyway

Seriously this might be one for a faq entry, how would I submit it to be added? Anyone else agree?

yes...
Mine also wont go above about 2,500 - 3,000 revs and about 20-30 mph when its been unused for a while - worse on a morning though. would this be related in any way?
Its booked into the garage next friday so i want to take as many possibilities as i can so they dont fill me with crap and chrge me for work they havent done.
Cheers

if it wont go over 3000rpm and the engine management light comes on, it usually means the car has gone into " safe mode"
might be a map sensor, it sounds like it cos my ex had the same prob on his vectra, the reason it does this is to prevent any further engine damage
id go to vaux and see wot they say tho mate

Cheers, it sorts itself out after a mile or two.....still embrrasing when you have to do the first couple of miles of your journey on the hards shoulder of the a19 in rush hour. Did his do that?
