Cylinder 2 Misfire

So £700ish for what I need plus extra for the pulleys and water pump etc? Unfortunately I can't afford all injectors to be replaced otherwise I would.

Check the total including all four, I don't have my receipts with me here, but I remember that the injectors themselves were not a major cost on the bill, it was the labour. I think they should be able to squeeze everything into £700.

Thanks. I'll see what they say and get a breakdown of the cost before committing. If I could get all the above done for £700 I might manage a half a smile.
 
New Injector / Timing Belt Kit + Pulleys / Spark Plugs / Water Pump / Rocker Cover Gasket £690 fitted....

Couldn't squeeze 4 injectors in this price....
 
Too bad that they can't do it for 700. Sorry if it sounded like putting a pressure on you about the injectors, I just wanted to help you avoid spending money on future injector replacements, which I hope you won't have to do!

I've gone myself through this procedure oil in spark plug. The job is big ,me and my brother do it alone for 10 12 hours. The biggest problem was un doing the crack shaft bolt. Even with my machine shop air compressor cant do it. The answer was a big arm ranch and 3 people to do it. So my suggestion for people ho have a oil in the spark plugs is ,go to a proper garage to do it. The difference is big wen the job is complete.
 
Update - Well it's been 3 weeks at the garage and still has a misfire. Injector 2 replaced and new plugs fitted. Also tried new coil packs and MAF and still none the wiser.

Would any of you guys and gals have any information as to what else to check or do. I will quite happily send the information onto the garage.

Thanks
 
Unfortunately, it seems to only leave a sticky or bent valve perhaps? I would recommend a compression test to see if that indicates a drop in pressure in that cylinder. (Sorry if you have already done this)

It's a long read with a few 'red herrings' thrown in but take a look at this thread - http://www.a2oc.net/forum/showthrea...ession-or-dealer-fast-one&p=169535#post169535 - It may be a knock sensor problem

Cheers Spike
 
Not sure it would help, I can only tell what I did before injectors replaced: I replaced fuel pump, fuel pressure regulator, fuel filter (3 times) and knock sensor (and other parts not related to fuel and injection). Every replacement eliminated misfiring for a period of time, from few days to few weeks, but it returned anyway.

Did you replace the fuel pump in the tank?

Have you had a compression test carried out? It is an essential test for this kind of problem?

Compression test results are 170PSI across all cylinders. The misfire has gone but the car starts and stalls now.

They've decided to get someone from VW/Audi in and diagnose what the problem is.

That is very good news, it gets expensive if any cylinders are down.

One more thing erliminated.

I have lost track of what you have tried so far (most things I imagine) but if it is one specific cylinder thne it does point to a coil problem perhaps (I am sure you tried that already)

Anything else (apart from spark plugs) is used by all 4 cylinders and so would not continually show as a cylinder number 2 misfire, it would be random cylinders.

It's had new plugs, coil packs, MAF, Injector 2.

Compression test results OK. They even took the entire exhaust system off to see if the CAT was blocked. They've decided to get a VW/Audi technician in to diagnose what's going on.

I will update when I know more.

This must be really frustrating and expensive for you.

But one way of looking at it is that you will have replaced all of the parts that usually give problems and a nicely running FSI is an amazing car!

Best of luck.

With what you have replaced i would hazard a guess at a wiring loom / electrical issue. All the best in getting some results back from the specialists.

i am sure you have done so already but worth advising them what works you have completed to narrow the fault down, saves paying the time for them to repeat your good work.

Has misfiring gone after the compression test?
