I asked for a smoke test on Sasturday but said they need the car for 4 hours & it was only open till lunch.  May have it done Tue.  Im almost convinced my issue is injector tbh.

MIke,

If you look at similar issues on the older s3/tt's when they mention missing on cylinder 3 they say it's the amplifier module, not the coilpack, but assume that's all built in on our coilpacks?

Found similar on mk4 site when I searched, and the symptoms were the same as ours; stuttering, hesitation under load and Shaking on idle.

Also took out the dipstick tonight and definitely made the engine rough the more pulled out. Exhaust tone sounded a little up then down in points, but may have always sounded like that at idle and I'm just imagining things  :smiley:

Mate,

Just picked my car up from APD performance.

She is back to full health, the culprit... SPARK PLUGS!

So guessing VW didn't replace them on the 40k, back in May!

Hope you have a similar outcome, but would suggest swapping them over...

Dom, were your spark plugs quite loose? Mine were only 5k old and were quite loose when I had them changed. Since changing them to a new set my stuttering has gone too. Don't know how they become loose over time...  :confused:

They're absolutely going to cause problems if not seated properly.  I'd imagine whoever installed them didn't torque them up correctly!

No, APD were under the impression that they were 'Old', and not been changed...

All is well now though... :

I have this and its driving me mad. I had spark plugs changed, dv valve changed and VW say they changed the coil packs on the recal but I dont really trust them. I took it in last week and they could see nothing wrong, its stuttering all over the place , when car has low fuel its unreal the stuttering. Half a tank or more its not nearly so bad .  Its booked into JKM now as I trust those guys to advise me what is up .


How VW cannot see it is beyond me, I even had the light come on twice on dash as it was missfiring . The one that says go to vw as it could damage your cat. Their machine couldnt pick this up , totals knobs IMO

soooo, a bit of a follow - up to the saga.

Car been in the garage for new discs and pads at the rear (and now new calipers due to them ceasing - not cheap are they1  :laugh:) but also for a full diagnostic test....

..... which did not pick up one single fault, they did a full sweep and even took it out on the road with the scan and nothing.

So wondering if it is the spark plugs - they weren't convinced as normally it wouldn't be an intermittant fault, when they are gone they are gone kinda thing.

So people - thoughts on that one?  :confused:

I went to JKM this weekend as my car is spluttering etc, as said before my DV valve, coil packs and spark plugs have all been changed in last 2 months.

They put the map back on and the the car was running at 1 bar, when it should be 1.4 bar ( maybe someone could explain all this bar stuff to me as never had a turbo before ? ) . The down pipe was spitting out oil so they changed this. ( The vw garage changed the air con condenser 2 weeks back so how they didnt see this is beyond me). Anyway part fitted and back to  1.4 bar. Still stuttering though. JPM advised me they had same problem with ED30 and it was spark plugs, I only just had spark plugs fitted 2 month back though. So we binned the Bosche plugs which are naff apparently and changed for NGK Iridium which are also a lot cheaper funny enough.  Stuttering has gone and now its fecking quick  :signLOL:


So my suggestion is to bin those nasty bosch plugs and fit some NGK's  :happy2:
