Title: Exhaust warning light flashing-whats the most likely fault? EDIT with fault code
Post by: winrya on July 04, 2010, 12:58:05 pm
Like many others recently I've been suffering a slight hesitation around 4000rpm.  On full throttle it feels like the car hesitates and then goes back on full power.  It seems like there may be similar stutters above this rpm but is much less noticable.

I took the car to votex in the week to see if it had logged any fault codes and it hadn't, he ran the computer watching the 4 cylinders on idle and there were no misfires.

At this point i was told to leave it to get worse as it could be plugs, coils or even injectors?

The car has now been sat for a few days and when I went out for a drive earlier the problem has suddently got much worse.

On full throttle it was stuttering (from 3500rpm) and would stop at 5000rpm but you could feel there was no power left above there.  I tried dropping to 3rd again and it did it again but the exhaust system warning light flashed on the display for a few seconds and went back off.

At this point I drove home normally and the car was completely normal in these conditions.

I now presume it will have logged a fault code and secondly, I expected the EPC light on a misfire (coils/sparks), does this indicate an exhaust problem?

Cheers for any input guys,

Ryan

Should i be presuming this is indeed a coil pack?  If so, should i replace just the one or all 4 and what about spark plugs?

The sparks were changes approx 6000 miles ago

Cheers

To confirm its a coilpack you can try moving it to another cylinder to see if the fault follows it  :happy2:

IMO if one coilpack goes bad, it's best to replace all 4 at the same time.

Would you suggest coil pack is most likely at this point as I'd rather not drive it around at this point?!

I would let G4V VW log the car.
You need to log, at minimum, blocks 015 and 016 and it should tell you whether or not a cylinder is misfiring.

I'd be more than happy to if i knew how to use it properly  :signLOL:
Havn't had it long and only good at reading codes and changing a few options (xenon's, seat belt chime etc) at the moment  :ashamed:

If anyone can tell me how i will do this for Ryan  :smiley:
Title: Re: Exhaust warning light flashing-whats the most likely fault? EDIT with fault code
Post by: bacillus on July 04, 2010, 11:02:54 pm
Just open vcds then click on the select button> click on 01-Engine> click on measuring blocks -08.
Put 015 in the first group box then click go. Do the same in the next lower box but use 016. After you've done that, click on Log at the bottom right corner.

Take the car to a clear bit of road and do a pull from 2 to 6.2k rpm in third gear. before you start click Start at the bottom of the screen and stop at the completion of the run. Then press done close. The file will be saved at C:\Ross Tech\logs. Post what you get here if you can't dechiper it. btw you must have Excel installed to view the file.

I'm thinking of swapping the coil pack, seeing if I can replicate the misfire and check if it has moved cylinder.

Do I need a special tool to remove the coil pack and is there a specific one i should swap cylinder 2 with or not.  Also, i presume they go left to right 1-4? 

Cheers guys and cheers Gav, looks like i may need your assistance again sorry :smiley:

There is a dedicated tool to remove the coilpacks safely but it can be done without it by using a long nose pair of pliers.

Right, got the coil packs out in the end and swapped number 2 with 3.  Now I'm still getting the hesitation on full boost as it drops on and off.  However I cannot now get it to pop up a fault light :sick:

Is there any chance this could be my DV leaking boost or does a misfire definately point where I'd already been looking?

God this is frustrating :sad1:

And also, should the coil packs look silver and shiny when used because neither were...

A light on the dash doesnt mean that the fault isnt there, read the codes and see if the missfire has swapped to the cylinder that you changed the coilpack to. A bit of discolouration is 100% normal, dont worry.

Thats good to hear ref the discolouration.   I didn't realise it logged a fault without a light on the dash.  When it was only occassional last thursday it didn't log any faults although it is much worse now.

If there are no faults do i need to start logging?

Thanks again,

Ryan

if there are no faults, bite the bullet and get yourself 4x plugs and 4x coils. (Seat main dealer are the cheapest for some odd reason)

Excellent thanks.  Are these the correct part number and a good price?.... http://www.dbcperformance.com/product_p/07k905715f.htm

Works out £79 for 4 delivered and what plugs would you recommend?

Thanks again

Are you sure about your pricing as the last time I looked, shipping charges to the UK were exorbitant...

Yes mate, $116 delivered so approx £80

Right, just checked for faults with gav and nothing has logged. It is clearly misfiring though and is getting worse each time I drive it. I'm going to order coils and plugs tomorrow, fingers crossed this fixes it. Thanks for everyones input!

your local Seat dealer will have them in for roughly the same price.

Nice one  :happy2:

Shall give them a call tomorrow. Audi want £29 plus vat each!

You don't happen to know the part number do you?

Cheers

Cheers, I was asking for part number to confirm that the above number was infact correct. Ive just seen coil packs coming off cars with 06 as the starting number and not 07

UPDATE!!

Just replaced the 4 coil packs and fingers crossed the car is fixed.  Just had a 15 minute drive and couldn't replicate any hesitancy at any point in the rev range and it now pulls much more freely to the red line.  Also idles much more smoothly.  The last time i took it out and gave it a thrash i was almost head butting the dash!

I'm very pleased and saved a nice amount by ordering from ecs above.  Cost £77 for 4 delivered and took only 4 working days to arrive :laugh:  Cheapest price I could get from dealers was £33 x 4 = £132

Time to get back to enjoying the car :party:
