Sports cats fitted nearly two years ago. Owned the car nearly four years, third owner, but have VAGCOMed it in the past and that fault never showed up

Hi All, I was wondering whether anybody out there could help decipher the cause/relevance/significance of the following codes that the S4 is now coughing up!!? 16815 Warm up catalyst; bank 2 P0431 - 001 - Efficiency below threshold - Intermittent - MIL O 16805 Warm up catalyst; bank 1 P0421 - 001 - ...

Just had car serviced and the dealer said they (audi) have changed oil from the castrol rs?

Do you know what they changed it to?

When you say 'it' went out of the window with the two kids, were you referring to the unit itself or the one with the fat fingers

Surely it's a no-brained!!! MRC every time.....YOUR engine mapped with the fuel YOU use with whatever mods you have already done. Not some yanky notion of what your car should perform like on the fuel they run in the US of A!!

Hi Youngben, Your RS looks absolutely stunning to say the least! If you don't mind me asking, how did you decide on your choice of detailers? I'm in Worcester myself and can't find any vaguely appealing that are in any way local, and don't really want to use any of the mobile detailers that are avai...

Trust me, they are not particularly easy to put on. I got mine from eBay a couple of years ago but they slept in the garage till about two months ago. Struggled getting the old ones off, (had to resort to stanley knife thus rendering them unusable), and slightly damaged the clutch pedal base (it's p...

Hi All Just thought I'd upload some pics of my new custom built exhaust from MIJ. I have a B6 cab but liked the quad pipe appearance of the B7 so swapped the valance for a B7 one to accommodate the pipe. Whole system was replaced...new down pipes without precats and sports cats where the old main ca...

TBH it was always my intention to relocate the sensors, because it is the norm, I just never got around to it. I thought it was purely luck going so long without a CEL. It may be due to the remap being performed with the sensors in the pre main cat position. I just do not know. Oddly enough since r...

I cannot comment on the avant or saloon but I have changed the diffuser on my B6 cab to one from a B7 cab. Undo two torx screws holding diffuser onto car. It may then be removable by pulling it backwards, however I removed the whole bumper so that I could see what was happening to prevent potential ...

I only relocated the main cat sensors. Oddly enough, I did not do this for about 1yr and in that time never had a CEL or problems getting through the MOT. In order to get the most out of the exhaust tweak the ECU will need to be tinkered with. Can I ask then why you moved them if they weren't causi...

Hi all. I know I'm resurrecting an old post but firstly I'd like to thank all of you who have responded to this and my other related thread. Anyway I took thar car in to MIJ first thing yesterday and after a brief discussion of my requirements, the fella seemed to be in complete denial that they had...

Hi,

I am soon having a custom pipe put on the B6 ....precats out and race cats replacing mains. Can anyone please let me know where all the lamda sensors need to go with respect to the cat on each bank to prevent any problems with the engine management etc.
