1.6 FSI Misfiring after Service/Timing Belt

Hi,

Got our 2002 1.6 FSI back from the dealer today after a full service and timing belt.

We live in Dublin and had it serviced in Belfast. My wife drove it back and it was running very well.

However, I went out in it this evening and it was fine for a mile or so. I stopped to fill it with petrol and it was fine again for another mile. Then it started misfiring on acceleration and the engine light flashed. It's running, but not very well at all. Fine at idle and slow driving, but misfires on acceleration.

I've heard that this could be a coil pack? We only have the car a few weeks and the PO had all four replaced about six months ago.

I really want to avoid taking it back up to the main dealer if possible. The PO gave me a spare coil pack. Is it worth trying it on each cylinder until hopefully I find the faulty one?

The plugs were also changed at the service so I suppose it could also be a faulty plug but I would have thought that a plug problem would have shown up immediately.

Is it possible that all the work on the car "upset" one of the coil packs? I believe they can fail if you look at them crooked.

Sods law. Why didn't it happen when we were driving away from the dealership:mad:

It might just be coincidence but could you have bought some contaminated fuel? Just a thought.
 
Just had a look under the bonnet. The coil pack on cylinder 4 had worked itself loose. Pushed it back in and all is working fine:). All coil packs are secure except for the one on cylinder 2. I can easily pull it off with my hand. Is there any way to tighten them?

Thanks,
 
Ken,

If there is something wrong with your car after it has been serviced by a main dealer, it is their problem, not yours. Clearly returning the car will cause you inconvenience, so what is stopping the main dealer driving a loan car to your house, taking your car back to be sorted and then bringing your car back and picking up the loan car? You are only 90 minutes down the road.

I would get a polite but firm letter off to Isaac Agnew describing the symptoms and asking them to put their customer care wheels in motion. Keep a copy of all correspondence in case Audi HQ need to get involved. You should expect a first class service, especially if you paid the first class price that you mentioned in your earlier post. Problems with the 1.6FSI engine not creating a spark are well known, so the dealer has no excuse for not checking that every is working and nothing is loose as you had to discover. It appears that something is wrong with their quality control.

I was in Agnew's on Saturday morning picking up a replacement dipstick and I think I saw your car. NICE! The two R8s sitting outside were nice too.

I changed my coil packs earlier this week. Drove 10 miles after doing it, all was fine.
Later that day I went for a longer run and engine started misfiring. One of my coil packs had worked loose.
I am certain I pushed them all down to the same level when I fitted them initially, so can't explain why this happened. Because of this I would go easy on Audi as I imagine its dificult to tell if the coils are properly seated.

Will be checking them regularly for next few 100 miles!
 
Thanks guys.

John - The two silver R8s were very nice. There was also a black one there as well.

I had a good look under the bonnet today and found another loose coil pack. No. 1 was being held in by suction alone so it wouldn't have been long before it caused a misfire also.

If both had gone, it's possible that my wife could have been stranded on the M1 in heavy rain. That wouldn't have been good.

I was going to call Agnews tomorrow to tell them I wasn't pleased. I think your suggestion is better. I will write to them. I paid £1,630 for the work and expect it to be first class. Not checking that the coil packs are seated correctly is sloppy.

Thankfully the car is now running well so I don't need to bring it back up, but there is a question of value for money.

The reason I stopped using Audi dealers down south was becasue of a series of similar issues.
