ok so im driving along as normal when suddenly the car develops a misfire , still drivable . I took the car back home and ran a check on the car as the engine fault light was on . tells me I have a misfire on cylinders 123 and 678 . any one know what could cause the front 6 cylinders to all misfire at the same time or know where to start looking for the fault . all coil sticks and plugs have been checked and are ok . any help would be great Riksta22.

VCDS codes? Without those no point in guessing.

As well as year (should matter as much) and your region/country.

h yeah sorry its a 2006 uk spec and this is the codes i got will be using vag com later today to see if it shows anything in more detail .

Yeah we are going to need the VCDS days to help.

VCDS is more specific, and can help narrow down a system causing the fault. OBD doesn't show everything.

Yeah, if you can get to an indy shop to scan the codes that would be great. Or where are you located as I'm sure there is a member on here that can help.

When where the coilpacks replaced, how about spark plugs?

Ok so my local garage has looked to the car and there are so many faults and there all comming from the 2nd ecu . They think there may be water damage to the ecu and thats whats causing the issues .

Hannibalacp82

So are they putting a new ecu in for you or sending you back to Audi?

riksta22

Sending it off to be checked and repaired if poss.or will need a new one.
