Help!!! UPDATE - possible ecu error

[c0v3rt]

I hope someone can help me?!?
Had my gti 2005 dsg (completely standard) a month with no probs, but today is different...

Had an emc and eps (swerving car symbol) lights come on when giving a little boost to overtake. These went out randomly after about half an hour at around 30mph of town driving.
Returned to car after 4hrs; I now have these lights back on, plus engine light. Car is juddering when stationary idling, and cannot drive over 5mph or change gear!

Please can someone help me! Car is currently in a car park and am 10miles from home grrr!

Cheers for reply Bacillus; I have recovery on my insurance, but was hoping not to resort to that yet.

On returning to car again after a couple of hrs, it starts ok-ish and managed to get home (with the same 3 lights on) but kept to 40mph and low rev.

I'm hopefully getting a scan next week to investigate, but am I ok to drive it carefully in the meantime?
It's my only car, and my girlfriend doesn't drive so am stuck without it.

Thanks!

I would say don't drive it till you've had it scanned.
Where are you located as hopefully a member off here with a vcds cable could scan the car for you for a few beer tokens.

Thanks 
I'm in Bedfordshire; Alex at AKS has offered to scan (had a service there only a few days ago and all was cool), but that is 10miles from me.

I suppose you could PM him and see if he could come out to you if no other vcds members are nearby. http://www.mk5golfgti.co.uk/forum/index.php?action=profile;u=1981

The other alternative, assuming you have Recovery,would be to call out your breakdown service first thing on Monday. They may be able to scan it for you and if they can't fix it, ask for the car to be taken to AKS

Car is now with AKS; scans point towards throttle body/pedal/sensors but will know more tomorrow hopefully.
Just hope it's not too expensive to sort!
Thanks for your advice Bacillus, and thanks to Alex at AKS for all the help so far - top bloke!

[Veee-dubber]

Fingers crossed its just a sensor chucking you into limp mode pal GL!

[c0v3rt]

Not solved yet, but throttle body has been removed and has some corrosion/ full of crap/ worn seal - will try get pics when I see Alex. I think the sensors are in a sealed housing, so can't be looked at.
New part due to go on tomorrow so hoping that clears it and am up and running again, fingers crossed eh!
Cheers

Update, and bad news...

New throttle body went on and it cleared the errors. Out on test drive its back in limp mode after a short while!
Disconnecting battery cleared this but keeps coming on when revved hard (over 2k rpm I think).

All scans/codes point towards throttle body or pedal - both these have been swapped for replacements and error still show, and goes into limp.
I'm told this now looks like ecu failure or a wiring issue somewhere.

Has anyone experienced anything like this, or had a replacement ecu fitted?

It's in with AKS currently, and will be ringing VW to see what I do next... Think this is going to get pricey!

[c0v3rt]

I'm booked in with Viindis Bedford VW for Monday so will find out more then.

Does anyone have any ideas of what causes ecu failure?
Is it something that should have been spotted pre purchase or at recent service'?
Or is it as random as a PC getting blue screen or ring of death thing on xbox's?!

Searching around the internet last night out it seems an ecu replace at vw is circa £1300 parts & labour.
Alternative to this seem to be sending ecu away to specialist company for examination, not sure on cost but cheaper than the other option!
If the ecu is knackered, would it be as straight forward as getting a ecu from a write off and swapping it in/ reflashing it?!

Sorry if this doesn't make sense; I'm not at all knowledgable wig cars and am feeling very lost with all this!
Thanks in advance.

sorry to hear of your troubles

don't buy a new ecu, a used one can be fitted.

send Kalu a pm

[c0v3rt]

Thanks Ed, I'll give him shout

[Eddie-NL]

Have the fault codes so we can have a look

[c0v3rt]

The fault codes shown when in limp mode were:

P0123
P2122
P0222

AKS did additional scans but don't think he noted them.
