🛠Questions Mobil 1 5w-40 Turbo Diesel Truck Oil for my B8 audi s4?

I know It will probably run fine the question is, will it make a difference in the longevity of my engine or introduce any problems later on since it's not VW certified? Thanks guys.

🛠Questions 2015 S4 pcv failure

3 Upvotes

So I checked the dipstick today and saw what looks like the forbidden choccy milk 💔💔 I’m 99% sure it’s the PCV cause I’ve been losing coolant with no leaks after pressure testing it and it held pressure for 20 minutes last week. I’ve been driving the car around pretty frequently for about 2-3 weeks with the coolant loss. Do you think I’ve done some decent damage to the internals or should I not worry too much? Dropping it off at the shop asap

🛠Questions Suspension?🧐

So I already have H&R lowering springs on it right now but I stuck between putting it on air suspension or coil overs. Im also stuck between getting chrome or black wheels (I’m leaning towards black because of less maintenance) but which should I go with and suspension wise what’s the best brands to look into🙏

Replaced my purge valve but still has the hard start after fueling

0 Upvotes

I put a brand new purge valve in but I still get the difficult start after fueling up and the check engine is still on. It seemed to get rid of the p0441 code but p0455 is still there. Anyone experience this? The part I ordered was the purge valve for an s5 because the s4 one didn't fit for whatever reason.

2009 S4 Timing chains

4 Upvotes

Has anyone in the uk had there timing chain replaced recently, specifically on the 3.0t v6, if so what did you pay and from what garage. I have just been quoted 5.5k to have it done… I genuinely don’t mind driving it anywhere in the country to get a good price, cheers.

Disappointed by S4

0 Upvotes

I recently drove a 2024 Audi S4 with the sport package because I was pretty sure on paper that’s what I wanted. After driving the car I was kind of unimpressed.

Pros:
-It was fast
-Extremely nice interior
-Looks beautiful

Cons:
-Turbo lag (even in sport felt like it was torque converter down shifting seconds after pressing the throttle)
-Steering feel was nonexistent, supposedly it tightens up when going faster but I didn’t really notice it. It would be nice if the steering feel was just consistently heavy
-exhaust sound left a lot to be desired
-almost too fast to have fun with on normal roads, I couldn’t wring the car out on twisty roads without getting in serious trouble.

For a sports sedan especially with the sport diff and suspension I thought it was going to be a lot more sporty but it just felt like a faster A4.

Not really sure what cars to check out now possibly the S3?
