Resurected from the dead post.... It was just a single coil on Cylinder 2. When I swapped it from one side to the other everything worked for 3 weeks and then Cylinder 6 started throwing up errors!! New coil from GSF and it works but shows an excuse fault!! Genuine previously enjoyed one on its way....

Warranty Direct took my last RS6 to a place near Bedford and the did it without removing the engine. Was perfect after and I think they paid out about 2k. I was a few years ago though!

I had a Navarra and Two Range Rover Sports in between my C5's hence why I joined here years ago. Sold the last Sport for 35K and bought my C5 RS6 for 10k. It was a no brainer to buy a C5 not a C6. The V8 is the best engine that have ever wrapped a car around. Get a C5 and put an aftermarket stereo s...

Everything Swapped from Bank one to Bank two. Lets see what happens now. I checked the fuses in behind and all ok. Haven't checked the normal ones yet. I believe I can spin up the fans in VCDS. I don't think its a boost leak as its lumpy at tickover. I will know tomorrow if its a coil/maf or plug. I...

No I didn't as Rugby, Tv and beer dragged me away!

Arghhhh All cleared down after battery disconnect and below is all that came back which are unrelated to the issue. Going like a rocket ship with no flashing dash issues and no codes. Business as usual I guess until lumpy tick over and low rev problems! Sunday,22,November,2015,17:07:45:62939 VCDS Ve...

I did but last night left the battery off so will take it for a run now to see if the checksum error goes too.
It was complaining about
Checksum
Coolant issue
Misfire Cylinder 2

Why do you think Bank 1 and 2 are such different temps in my EGT readings?
250c vs 295c

Hi Clever people. I am guessing MAF as I presume they should have the same readings? From the earlier post I can see a huge difference in Exhaust temps so I guess Bank one isn't burning its fuel hence a fuel smell in the car sometimes.

learning loads here its a pretty cool tool!

Thanks Guys. I did check the EGT and on idle both were 5C away from each other. I guess it did say intermittent. Will drive it with the laptop on the seat and see what it says in the higher range. Only went up to 385 in the garage with a bit of Rev. The air filters were very black so did an early sw...

Perfect link for the EGT

Hi to all clever people. Just as I decide that we must part company My RS decided to play up! The ICM has aways been there and I believe is the Remap done by APC 5 years ago! The two coolant one I can look at. The others I am unsure of. Is it a vacuum leak, MAFs or N75? It rough idles frequently now...
