Ok. This is my 1st major post on here so here goes....

I was driving back from Newquay mid July got approx 15 miles from the motorway and suffered major power loss (was pressing the accelerator and nothing was happening). I pulled over and gave it a few presses on the accelerator and nothing, the engine was struggling and the rev's were very low. I turned the engine off opened the bonnet nothing smelt strange. I left it for 15 mins approx and fired the car up, it started but was spluttery. I left on tick over for 5 mins and tried to pull off. The car was struggling with low rev's and little power.

I finally pulled off but something was not right when I tried to accelorate there was a pause as if the engine was stalling ( I could feel it on my accelerater peddle ) then it suddenly bust into life and accelerated. But as soon as I dropped the power i.e got close to someone and tried to accerlerate the car would do this pause thing.

The drive back on the motorway was hard work, the car was happy doing 70 *cough cough* but as soon as I slowed it did not like it.

Anyway I got back to Brum struggled to get the car up my steep drive and there it sat on my drive for 5 days. In betwwen that I had called my dealership and they said we can fit you in Friday (I called on the Monday).

So Friday came off to the dealership the car struggled to start and limped around the corner and then went fine drove great with no issues. I got to the dealership and they stuck it on the computer. They reported back saying the car was fine there was some miss fires but nothing else.

They told me that there had been a fault with all the throttle bodies with my age of car and it was probably that what was causing the problem and quoted me £400 fitted for a new one.

The car has drove fine up until yesterday and the spluttering and pausing came back no where as bad as the trip home on the motorway.

I have a couple of questions.

1. Does it sould like the throttle body is faulty ?

2. Has anyone experienced the same problem ?

3. Does anyone live in Brum have the VAG-COM software so they could do me a diagnostic ?

Thanks...sorry its a big post.

Hm sounds like the coil pack to me - not good driving like that either as I believe you can damage the cat :/

Mine did this on my 1.8T Superb. I seem to remember that we changed a coil pack and this resolved the issue

I would go for coil packs as well....

I have had all my coil packs changed recently (lasst 12 months) and the dealership said the colis packs were ok (sorry I did not include, the post was getting long)

Poor/loose connection to one of the packs maybe?

iirc is is possible clean the TB, so could be worth giving that a go. I drive a diesel, so can't help much more (only with what I have read on here).

If the dealers computer is only showing a few miss-fires, then I don't believe that vag-com will give any more info....

Not strictly true. Many VAG engines have misfire detection which will shut off the fuel injector on the cylinder that's not firing to prevent catalyst damage. It might not be so bad after all......

i had summin like this but with my bike! and i died on the way to lemans. when i finally got it to my mates garage, it would run but not for long and i would cut out or struggle like there was no fuel gettin to the engine

anyway he said it was running on 3 cylinders it was missing one or two out every time cause of poor spark, hence the coil packs and ditributor that ran them, on investigation my bike had burnt one coil pack out but needed all 4 replaced to have it running proply, after this and 500 notes later its running top! hope this helps

i think coil packs on them cars are qiute easy to change?
