Hello,

I have a 2003 A6 with just over 103,000 miles, last night on my way home my car went into 'limp' mode 3 times with the Check Engine light blinking. The it only lasted for about 10 seconds and maybe 5 minutes in between incident. I was very on gas and the warning chimed and then a few minutes later this happened. I have not ran a vag-com diag, but I wanted to see have anyone else experienced this also, or what should be my first corrective measure.

Thanks,

audifirst

run Vagcom first and post the error code that got stored then we can check what is wrong

Airbag

does the same col feed cylinders 1 and 4 ? if so swap with another one. sounds like a coil pack

PapatoeSC

i had the same issue like 2 moths ago and i had to replace 2 fuel injector and repair the other 4

nyc.turbo

Had that happen at WOT a couple years back . I cleared codes and it never happened again . I think it was bad gas in my case.

Mattjordan

Okay I just got the coil packs and I am about to replace them but..... how do I know which are cylinders #1 & 4?????

audifirst

there should be sticker either on the hood or on the top front of the radiator support , or check manual there is a diagram of the engine and cylinder numbers

This is a what Bentley says for 2003 A6 with 3.0L V6.

Top photo is passenger side, bottom photo is drivers side. So, cyls #1 and #4 are at front on each bank, closest to cam gear (timing belt).
