Help Required... Running Issue....

[Le S2 Audi]

Excellent! Hopefully it has been sorted
One last bit of advice, if you need to reset the ecu, you just need to pull the two fuses in the middle marked 'MOTEUR' or however it is spelt!

Thanks Dest...

Noted for future...

Funny, I had the exact same problem on Thursday - first time I'd taken the Avant out of the garage in 2 weeks, and first time about 3 weeks I'd actually had chance to put my foot to the floor for more than a few seconds. It was fine below 1bar boost, but as soon as I let the needle get above that it felt like I'd hit the redline. Violent, sudden juddering.

Perhaps it was something to do with the weather? Because Friday I took the car out and it pulled like a train, 1.3bar no problem. I was going to say, perhaps it was damp if you'd not driven the car for 10 days but looks like you found the problem - and I may want to clean my MAF, check for leaks and reset codes, then go out for another test-drive to be sure...

Thats WIERD!!!

Same issue - same day.... SPOOKEY

She had been sat for a few days, but had driven it to work in the morning without an issues but I wasn't pushing her as I was low on fuel...

Assuming mine gets running again tomorrow the front bumper needs to come off anyway so I thin I'll take the time to go and double check all hoses. Thinking the ignition amp was a red herring now.

Glad its sorted though

Thanks!!!

If you have the bumper off and you haven't done the Mark H Mod... I would highly recommend that you do it...

That's where I had my first major boost leak after fitting Paul's Homefried ECU...

Its on the list of things to look at down there I remeber that silly bit of hose/o-ring being mentioned before as one to look at. Got a linky for the mod/kit?

We have a road near us which is a 3 mile straight and had her flat out and no sign of any issues... Tried her both at full pelt all the way through the gears and also tried her from slower speeds with my foot flat to the floor...

Where is this 3mile straight? It may come in handy for 'evaluation' purposes:mischeif:

Good work on fixing it

Note the second post in this thread..

There's a whole thread I started a year or two ago about the MAF connector, sometimes a wiggle will do it I eventualy took the pins out of the connector one by one and cleaned the contact surfaces with an old piece of 1000 grade wet and dry lubed with wd40, then coated them in silicon grease and clicked them back in, I've not had the problem since and it has been occuring on and off since I've had the car (8 years? ).

Exactly same thing happened here... second time in about two years... severe kangaroo juddering when accelerating hard, past about 3,000rpm... yet totally finw ehen you ease back a little or just drive gently.

Newsh has it right... I disconnected the MAFF connector (as shown in previous pic in this thread) and spreayed it with contact cleaner..re-connected..and hey presto back to full power.
