Facking coil packs! 5 gone at once- how????

[hman]

So I'm driving home from work and the car starts misfiring plus the engine light starts flashing.

Ring Audi, telling them I'll be there in an hour and to ready a coil pack.

Arrive at Audi, Jessica deals with the paperwork, I leave.

Get a call from Jessica at Audi, 5 COIL PACKS HAVE FAILED???

£299 thanks.


Hold on, you need at least half the engine to be firing to make it turn over, so I ask them to check and lo and behold the oscillosope of doom reveals only 1 isn't making a spark, but the rest are reading faults.

So I ask them to replace one and return the car- they say OK but expect the others to fail soon.


Is this the case or was the duff one giving weird faults so it looked like another 4 were duff?

Also the coolant temp sensor is fooked, and so are the front arms (bought the set from meyler HD) fitting on saturday.

Did I mention my bosch washing machine packed up this week as well? guess thats my three then!

I had a coil go on my A4 2.0tfsi quatro SE , then a few days later another went leaving me stranded at the side of the road twice within 10 days of ownership. Audi did pay for the other two to be replaced as well, just in case. They are a very weak part on Audi cars.

All 5 needing replacing sounds like codswallop to me. Had a couple go, one at a time on my old TT but it never affected any of the others. I had the car for 7 years - the first failed after 2 so I had plenty of time to see if there would be follow on problems. Unless there is an underlying fault why would all 5 go? They are separate parts.

Not sure how similar the BMW setup is but I remember my dad getting fed the same stuff by a dealership. Luckily he was under warranty so never bothered questioning it.

The usual one we see is people having their engine bays steam cleaned, coil packs do not like it one bit.

True that.

Also, take off any plastic covering the engine.

How old is the car? Audi warrant then for 5 years.

We have a SEAT in the family and one of the coil packs has failed every year since we owned it (5 years). I'm not happy about it as it's my daughter's car and I helped her buy new to avoid having a banger that would break down all the time!

Bizzarely, it's always the same one (no 1), and as the car only has 3cyl's it doesn't work very well when a coil pack goes. Bought a spare on eBay for a fiver to keep in the car.

Coil packs are a weak point on most VAG cars, in my experience anyway.. had one go on mine, my mate keeps four spare in the boot of his 1.6 mk4 golf.
The VW assistance guys (rac) were also told to change the newer type on golfs irrespective of whether they were faulty or not - that's what he told me a few years back.

IIRC, VW sued the manufacturer of the coil packs over the issue.

Coolant temp sensor is another as is the water pump impeller, window regulators, rear window washer and the stock (Bosch, I think) DV.

Best getting genuine items too as they seem to be more reliable than countparts.

None of the 1.8T's owned by me and my friends have had coil pack issues so while it may be though as common it certainly doesnt effect everyone.

And the cam follower on the 2.0TFSI and the DMF on nearly all of them and the oil pump drive on the 2.0PDTDI and the console bushes on anything on the PQ24 platform and the gearboxes on the 6N Polo GTI and the N75 valve and the...

OK!


I think we can close this here.

Only 1 coil pack had gone, the others were being affected by the duff one.

Replaced coil 2, all faults gone ( had temp sensor replaced)


So if the mods would like to close this VAG common fault thread that would be great.
