From reading a number of VW based forums I think I need to get the Coil Packs replaced.

Very lumpy from a cold start, definite misfire going on. As the car warms up it improves some, but there is definitely some lumpyness and "hunting" going on.

Seems Coil Packs needing to be replaced is quite common.

 

Just wondered what kind of damage I'm looking at in the pocket for this work?

Obviously Christmas coming, don't want to over-spend

Am I better off potentially sourcing the parts myself and them asking a garage to fit (if they will of course)?

 

Cheers.

Scan the car for error codes. Misfires logged will point you to the correct cylinder, so then you could change the pack and/or check/change the plug on that one cylinder and see if it makes a difference.

1/4 the cost of changing them all.

As above, try and identify the problem one first. Cheapest will be DIY, it is an easy 15 min job.  Check with TPS for genuine or put reg in ECP but from memory you can get Bosch OEM spec ones from ECP for about £35 each, less any of their promotional discounts!

No point paying someone to do coil packs; it's very easy DIY job.

Cheers for the replies.

Once upon a time I wasn't scared to do things on my car - I am a little more so these days

I'll see if Google has any videos showing how to replace.

 

I've been quoted

 

1 - £64.53

2 - £119.47

3 - £169.60

4 - £210.14

 

That is parts, labour and including VAT.

He seems to think it would be highly unlikely all 4 would need replacing.

Sounds like the thing I'm looking for?

I'll check fault codes over the weekend and see how many I need before ordering.

Look right to me. I've found ECP part numbers are hard to cross reference because they are usually their own sku numbers not the manufacturer part number. Makes it a pain in the ...... You can call them before hand and get the detail or double check the part number and cross reference when you get it.

PS. if you search for plug change or coil pack change for your model / engine you should find something but it is straight forward. Engine cover removal, wring harness unclip, lift off coil pack, may need to use a couple of cable ties and a bar for leverage, fit new coil pack, reclip harness, refit cover.

So...

I've just been out to the car and I've interrogated it with both Carista and Torque and there are no error codes to be found....at all.

I've checked both current and historic and nothing.

My car had n inlet manifold replaced some months ago, so I'm assuming all codes were wiped at the time and the car has nothing to report.

Not sure how to proceed from here - I'm assuming dealer level diagnostics are going to provide nothing more than I can already see.

Does this car have a dmf?

My answer to that is only - depends what came as standard on a Petrol Octy vRS from 2011. Nothing flywheel has been touched on my car.

I had various coil packs go on my passat. You will know when it fails as it will run like a pile of the brown stuff.

They are a common thing to go and I'd get one and keep it in the boot.

Last one cost between £15 and £25 from memory, bit it was a few years back. Very easy to change.

Cheers for all the posts.

Still not sure if it's worth me getting 4 and just changing them or getting some diags run to see exactly where the problem is and just fix the problem areas.

I'll report back once it's sorted - just for completion of the thread.

Unplug one at a time (Unplug at the top) see if it makes any difference. If it doesnt then it's that one that need replacing.

So, a little update.

Had the car in for some diagnostics today.

They reported there is a high misfire count on Cylinder 2.

They moved the coil packs around and also replaced the sparkplug - misfire didn't move, it remained on Cylinder 2.

Told the next step is they investigate the injector - so I'm looking at labour to get that checked (somewhere around £140) and then £160+vat for an injector and then fitting on top.

So my £21 for a new ignition coil pack is now becoming a £500 repair.

 

I had a new inlet manifold fitted to the car around 6 months ago. The place currently working on my car have suggested I get back in touch with the main dealer who fitted that and explain that since then there has been a misfire, which I've coped with, but now the weather is colder it is worse.

Any mileage in that option??

So I'm presuming it's the TSi engine? Did the garage that fitted your inlet manifold clean the inlet valves of carbon? These engines are well known for cocking up.

No idea - I'd guess probably not. Was done by a main dealer and we all know they are interested only in maximising profit.

I'm going to try a "DIY clean" - So a shot of Redex Advanced along with a full tank of Shell V-Power. Get those additives flowing and see if a clean helps at all.

Bottom line at the moment is I cannot afford to have injectors replaced - so if I've got to live with it for a while I'll try anything if it may help (£16 for the Redex).

What mileage is your car on? It might just be carbon build up. Time consuming i know but if you can do it yourself cheap enough to do.

About 80k

Car maintenance is a little outside my area of expertise.

I can do a service on a car without issue and I'm happy playing around with the "odd little thing" - but the car is used most days for work and I cannot be in a situation where something goes wrong when I'm doing something I'm not really sure about.

Don't have the tools nor the covered space to rally do this kind of thing, hence the reason I'm at the mercy of garages and their lovely labour charges.

My plan was to keep the car for at least another 2-3 years, so I guess it's something I will have to sort out, but it'll just have to wait until the festive period is over and then I'll have to find the place offering the best "bang for buck" on doing the work

Im sure ive read on here over the last few years that there has been a few VRS TSI owners that have had injector issues & have needed to replace one or all of them.

That will do nothing for the inlet valves.  Direct injection bipasses the inlet

Argh.

I'm familiar with how direct injection works, however you're the first to mention valves as a potential reason this is happening.

Coil packs / Sparkplug was cheap and easy, a new injector would be pricey but if we get into the realms of valve issues then I am in trouble.

Correct, but it may clean up lightly gunked injectors.
