MisFire 05 2.0T FSI - Not Coil Packs

[aletank]

Hi guys - Car is a 05 A4 2.0T FSi S-Line 131k miles
I've only bought the car about 2 weeks back, on Friday I took it to EB Jones of Liverpool (Audi Specialist) for a Full Service and a Air Bag Light reset - all was good ! , they said it looks like the engine had been steam cleaned as there was signs of water on the Coil Pack but still OK.
On the Monday I took the car to http://www.smart-autos.co.uk/ for a Air Con regas, after the Regas, about a mile down the road the Engine Light came on and the car was runnin very poor and about to cut out at low revs.
I took the car back to Smart-Autos who said they could put it on their computer for £35+vat but the problem sounds like a Coil Pack failed which matched up to what EB jones had said on the Friday. I thought that by the time the put it on the computer,fitted a new Coil Pack etc that the bill would of been £80ish for just one Coil Pack.
I said I'll take the car home and fit 4 new Coil Packs myself for £100/120.
EB Jones in next door to GSF so I called in there and explained the situation, they said they didn't think the Coil Packs where bad enough to fail so they said bring the car in to put it on the computer (no charge)
They said cylinder 2 & 3 was Misfiring so we swopped the Coil Packs over from 1 & 4 but the problem stayed on 2 & 3, we then fitted 2 new Spark Plugs but the problem was still there.
I left the car with them but they have been too busy to look at it all week, hopefully they said they'll get a chance next week.
I mentioned to him if the Injectors could be the problem and he said actually that is what the computer is sayin the problem is, So he said he is goin to start to strip the Injectors and if not too much trouble swop them over like we did with the Coil Packs.
I added a little RedEx to the petrol on the Saturday - maybe this has caused the problem ?
How big a job is it to get to the Injectors ?
What do Injectors cost ?
Any Ideas/thoughts guys ?
Much Appreciated
PS - Sorry for the long post - Just gettin all the info in

the injectors are low down and you have to remove quite a bit to get to them
not a easy fast job

EB Jones (Audi Specialist) Have now stripped the car down to the Injectors they have checked the fuel pressure from the pump, checked the Tumblers in the Manafold and now want to change 2 & 3 Injectors, £130 each + 4 hours labour charge £164.
They say they aren't 100% sure the Injectors are the problem, they haven't got the info for the fault codes.

The fault codes are 00616 & 00613

I've told them to hang fire until I can try and find out exactly what these fault codes are - Anyone know ?

Thanks Guys

only things i can find on them codes are
00616 ignition output 8
00613 ignition output 5

Would you now be changing the Injectors ?

i have no idea
what scanned was used to pull the codes?
iv never heard of the injectors paxking up on a tfsi tho
maybe A8 or crasher could give you some input

Thanks for the replies
I don't know what scanner it was to find the codes.
It was a hand held screen about the size of a A4 folder if that is any help

Our Mark said you posted on a forum so its a good job its this one.

The codes are from a snap on or bosch reader and there no good with vag com or vas pc for understanding what's going on.

If you can drive down to ours I will scan it properly for you and then let you now what's going on

If you can't drive it then I will come to you or get a vag com scan of address 01 plus the fuel rail pressure

here is a tip

first make sure you have the correct coil packs fitted

Engine doesn’t run correctly.

Fault memory entry: sporadically/static misfiring.


Injection valves or ignition coils.

Measure

Before replacing any components proceed as follows:

Check the contacts on the injection valves and ignition coils.

Take off the plug on the injection valve/ignition coil.
Remove the plug contacts from the housing (for injection valves - see attachment-
Attachment 8871

not applicable to all vehicle types: press the plug out of the carrier - push back the clip A, pull up the secondary lock B, push up the clip C with ejector D and pull out the contact).
Place the plug contacts in turn on the pins of the injection valves/ignition coils. It must be possible to push on the contacts while they cling on strongly. The contacts are so-called high pressure contacts, they are used so that sufficient contact is made at high temperatures and vibrations. Contacts easier to push on must be replaced

Thanks for that Jon!
I'm goin to go to EB Jones tomorrow and tell them to put the car back to the way it was - I'm expectin them to charge me the 4hrs they spent on it today.
Mark said I can use his AA to get the car to you, the car drives but only on 2 cylinders and is about to cut out at low revs and traffic lights, not sure what it would be like on them there hills !
The Coil Packs are the original ones that was on the car when I got it, so it has been runnin right with them until now and Lee who i got the car from isn't the type to mess with things.

No problem, drop it off and I will have a look for you.
