VW bora V6 4motion - engine problem

[sim2002]

Hi everyone,

new to the forum and new to VW!

Im having first problem with my Bora V6 and if any body can tell me the problem with the car.
(difficult to explain but car sounds and feels lumpy around 2000rpm, the engine not revving smooth as previously (even steering feels bumpy around 2000rpm then disappears)- different noise coming from muffler too in lower revs - i think some power has also been lost in acceleration.)
no engine warning light has come on and the car is still running - no stalling)
also feels very slightly when driving there is slight urging in engine when driving along about 25oorpm?
all
basically feels like a cylinder has gone?

can anybody help me out?

thanks,
simon

Welcome!

Weclome to our forum! Lots of knowledgeable people here (and some with VAGCOM ) Might save you a lot of time and money.

ud know if u were running on 5 cyls.
I was the other day when i forgot to put one of my plugs back onto the coil. The car makes a real farty noise instead of the sweet vr6 noise as u try and accelerate. and u lose a LOT of power. Still quicker than a 4cyl tho
But yeah. where abouts are u? maybe a quick vag-com scan could unearth something.

cool! thanks for the welcome!

what is this vag-com scan?

yeah tim does have that 'farty noise instead of smooth pur'

im located inner sydney

its a small device that allows you to read fault codes from the cars computer.
If its making that noise id check all of your leads are seated nicely on the coilpack.
i once also got a similar thing with my car when i had a cracked lead. and the spark was escaping and arcing onto the cylinder head. If u rev the car in the dark any sparks that are leaking should show up.

late VR6's run coilpacks

It'd be a good idea to put your location in with your name so we may be able to direct you to someone locally who might be able to help.

vag-com can be read about on www.ross-tech.com

I am thinking not a coilpack as it isn't throwing a checklight on.

I had a problem with the MAF (air fow sensor) on mine. It would play up especially when cold. It would miss and generally run below par but was OK under full acceleration when warm. The people in the know tell me that if you disconnect the MAF and the car runs better then its a fairly sure sign that it is buggered.

It took the local VW stealer about 3 visits and quite a few dollars, new temp sensor (no difference), new spark plugs (the same) and eventually diagnosed it as the MAF.

BTW they tried to charge $850.00 for a new one but luckily at the time I had a friend in the UK who e-mailed me a parts quote from Breeze VW that worked out to around AU$250.00. They do them exchange over there and would refund you around AU$50.00 off the $250.00 if you give them the old one. When confronted with that the dealer replaced it for $330.00!!!

Don't know if this will help.

Most of the single coil pack cars with DBW have fault codes for coil pack misfires

With or without getting a check Seb?

Usually no check engine light

Hey,

just let everyone know on what problem was with my car:

was running on 2 cyl., the MAF has died?, oxygen sensor needs replacing, coilpacks gone, spark plugs fowled and need another throttle body?? (this is what mechanic told me) and just to top it off when i got to mechanic the driver window just crunched and died??

im just wondwering what could cause such problems??

always used premium fuel never thrashed car always been serviced!?

anyhow there you go!

[Bug_racer]

If the car still starts and runs I call bullshait .

If the MAF , Throttle body and lambda probe are dead there is no engine to ecu inputs . How much fuel / timing does the ecu give if all it has is a crank angle sensor to tell it the position of the crank to the cams the coolant temperature and the outside air temp !!!!
