UKPassats

SORTED!

It was the ICM.

I bought one online and the misfire has disappeared. 

All cylinders now firing.

Thank you for your help.

Top man!

That's good...you've found something that isn't working. I think you've already swapped over the individual coil modules to prove they all work, but I suppose it's worth double checking by swapping the No.3 coil with another one to confirm that (1) the No.3 plug still does not spark and (2) the ori...

Yes, i have tried swapping the coils, same result.
Cylinder 3 doesn't fire.
So you think it's the ICM?
Anyway to test it to be sure?

If you remove the spark plug, connect it to the coil pack and earth the plug body, you can start the car and check that the plug sparks to ascertain if the coil and plug are working correctly. Before you start the engine you could either screw an old plug in the plug hole, or perhaps leave that cyl...

Ok, thank you.
It's a bit of a crazy period at work, so not much spare time atm.
Please bear with me.
Monday morning I should be able to test this.
Thanks.

How strong is the vacuum?
Am I at risk of getting a rug in the engine?

This has my same engine.
Should I follow this to remove the injectors or do you have any further tip?
Thanks

Ok, now the problem is where to find instructions to remove the injectors...
It's an AEB engine

Thank you, I'll try that tomorrow and let you know how it goes (on late shift today)
Are you thinking of a clogged injector?

Yes, everything you said is correct.
There was no petrol in the cylinder when i removed the spark plug.
My thinking is that even if the cylinder was running dry, if the spark plug was sparking, there would be some signs of burning on it (or maybe not)?

Thanks for the info. I changed the temperature sensor a few years ago because I had a problem with engine running cold. Eventually it was the thermostat. Yes, the fuel consumption is very poor, 200miles on the last full tank. Anyhow, today I spent a bit of time to find the fault. I attach pictures f...

Ok, I tried that trick and car run worse on every coil pack I disconnected.
I also tried swapping a new coil pack with each one of the existing and made no difference.
Checked all wires and they're perfect.
What's next???

Will try and report back.
Thanks

Hi everyone, my B5 1.8T has developed a misfire on low revs. I changed the spark plugs with original ones but the fault remains. Considering that I will probably have to get rid of this baby because of ULEZ, I don't want to spend much money on it but I need to run it for another couple of months. My...

Michelin Cross Climate + XL.
I had them for 3 years and liked them so much I had them fitted on my Audi.

Yes, it's a straight swap, but I've given it away now.
Sorry.

Hi, I replaced my seat because it was of different cloth from original.
The seat is dry and fairly clean.
If interested let me know but at first rain i will have to scrap it.
Collection from Heathrow area.
Thanks

Hi everyone, got to replace my headlights despite polishing them all the time because at last mot i was told and shown that the image is very poor. My B5 doesn't have front fog light, but other B5 do as you know. If I buy the headlights with fog lights, can I simply not put the bulb in there? Would ...

It was my pleasure. I recommend Aidan to all Passat owners. I thought I was mental using a torque wrench all the time, demineralised water for coolant and screenwash, etc, but no, Aidan does that and more :-bd I wish more mechanics and tradesmen in general took that much pride in their work. It was ...

Thanks for this.
I ordered the round design driveshaft.

This exploded view shows both, flanged and round (1 and 2).
So mine seems to be round, correct?

Yes, probably both flanged and round will fit.
Based on the picture i posted, they're round, aren't they?

I just found this picture of the car's underside.

Mine is definitely round like your first picture.
I pm the info just to be sure.
Thanks
