I've recently installed a Superchips Bluefin remap onto my TTS after 2 years of ownership and I honestly can't believe I didn't do it sooner. I can't comment on long term reliability as I've only had it on a few weeks, but the difference it's made to the car is very noticeable, and in a very good way! My car has excellent service history and I think as long as you do your proper maintenance you're not going to have problems. Just bare in mind that if there are already underlying issues the remap may well highlight the problems due to the extra strain being put on the engine and components. My opinion is make sure the car is mechanically sound and, if so, go for it! You definitely won't regret it!

Hello, I seem to have oil leaking from below my alternator. I'd checked the belt a week or so ago so it's a recent development. My concern is it could lead to the belt slipping and/or coming off which is a real pain in the backside. I snapped a few photos, has anyone had a similar issue? Any advice on where this is coming from would be great, I can't see the source because whatever it is, is below the alternator. The underside is covered and because of the belt it's also sprayed about a bit. Thanks in advance.

So... I've had this problem since I bought my S4. The previous owner said he'd replaced the sensor with a genuine part just before selling it but if I'm honest I have my doubts. The sensor looks brand new but genuine is debatable, cheap eBay jobby looks more realistic. I only have a basic fault reader (not VCDS) and this shows an issue with the driver side pre-cat/upstream sensor. I'll scan the code again and add an update, as I can't remember exactly what it was. What I'm wondering is whether this issue could be caused by the Milltek sports cats? I know that sports cats can cause problems with lambda sensors, but I would have expected it to be post-cat/downstream sensors. If anyone has had a similar problem I'd appreciate some input. Audi want around £180 for a new sensor and I really don't know if this will solve the problem. The wiring all looks good so I don't think that's the issue. My next step is to swap the two pre-cat sensors, and see if the fault changes to the other bank. If so, faulty sensor. If not, it's a whole different problem. For anyone that's changed the pre-cat sensors on a B7 S4 I'm sure you'll appreciate that this isn't a 5 minute job. I should also note that I've had a few misfire codes on random cylinders. I've never felt a misfire but it is a little rough on idle sometimes. I thought the lambda code may have been related to the misfire initially so changed out the coils and plugs. The coil packs and spark plugs are now brand new (both NGK) so this shouldn't be the issue. I suspect it's linked to the lambda fault, but I could of course be wrong. Am I missing something obvious? Is it the sports cats? Is the misfire likely to be related? Any input would be greatly appreciated.

Hello all! Just thought I'd take the time to say hello and introduce myself. I'm Ian and I live in the East of England just outside of Norwich. I got my first Audi in 2015 when I bought my TTS and went on to buy a B7 S4 avant last year because I needed a "practical" car for the dog and my fishing gear. Both cars are totally different animals but I absolutely love them both! I've just installed a Bluefin on the TTS (can't believe I didn't do it sooner!) and I'm bow itching for more mods! The S4 fortunately came with a full Milltek system, but also an abundance of faults which I'm slowly working my way through. No doubt I'll be asking you all for help and advice on both the modding of the TTS and the numerous issues with the S4, and hopefully I'll be able to return the favour sometime. So that's me! I look forward to learning something new and hopefully making a useful contribution!
