Hi All,

For a while now (matter of months) my B4 has been starting very rough in the mornings, usually when it is below a certain temperature. I turn the key and it takes a little bit longer to turn over, and when it does it will:

• Turn over then rev up a little, go right down again, and then conk out.
• Sputter really badly (to the point where the whole car shakes) for about 10-15 seconds then the idle will even out. After this happens and I put my foot down on the accelerator slowly, the car feels "stuck" as if it's only accelerating at a fraction of the speed it should. After about 4-5 seconds the acceleration feels 'normal' again and the car behaves as it should.

Both of these may occur or just the second one depending on how cold it is outside.

Once the car gets going it seems to be fine; Idle seems normal, and it doesn't ever cut out while I'm driving. I suppose I'm just a little concerned for the engine's well-being. I've spun a big end bearing already and really don't want a repeat of that. I would take it in to S&J but they'd need the car for at least a whole day or two so that they can replicate the issue. If possible I'd like to find any potential DIY solutions to this, as relying on public transport to get to work is hopeless in SA.

Using general knowledge and what I've found online, I was thinking that the issue could be related to either:

• The MAF sensor
• The fuel filter

I didn't list the battery as I assumed that the engine turning over implies the battery is ok (not sure on that though). If anyone else has any suggestions of things I could have a look at before having to consult a mechanic then I would appreciate it immensely!

Cheers!
