RS4 Puff Smoke

[Duncan]

Guys,

Before I run to the dealers, I thought I'd do a brain pick here. Car is an RS4 from Mar-07, so still in warranty by 2 days!

I have seen in the past a puff of smoke when giving it pedal to the floor acceleration revving towards the red line along with with quick shifting. I've only really noticed it at night when the mirrors of cars behind me showed up the puff. The other day I was overtaking in daylight and floored the throttle. Checking in my rear view after I overtook and as I changed up, I noticed the tell tale puff.

Anything to worry about or is this normal behaviour when flooring it, and something I've just not noticed as I spend the majority of the time looking where I'm going rather than where I've been?

Car has just come back from the second service and nothing was noted about oil consumption etc.. The need for me to top up the oil is so rare I can't remember the last time. Possibly last summer.

Thanks,

Duncan

Get the dealer to check it NOW before the warranty runs out!!

Take it down there and tell them you want it checked over BEFORE it runs out!

Calm down Soovy This is normal for an RS4. They do use oil and they do smoke a bit when hoofed. Unless it's really excessive you should be fine.

If your warranty is about out it's a good idea to book a quick health check with Audi just in case, you can get them to do your first MOT at the same time.

Theres a software update for smoking on rs4s to adjust the fueling. I think this was only on startup to be honest but worth telling them that its smoky on startup aswel just to make sure this isnt the issue

I've had this update and mine still smokes when I boot it.

I assume you've just had it MOT'ed too? How'd it do on emissions?

My car's a bit smoky on start up (also noticeable when stationary at traffic lights) but I'm not concerned - got through its first MoT (last week) OK and all good on service.

As mentioned, the cars do burn oil and, of course, it's been quite cold of late which makes any smokiness far more obvious.

Guys, thanks for your feedback. I suspected that it would be "they all do that, Sir!", but I'll chat to the dealer nonetheless.

No MOT yet. Back in next week for front suspension replacement (under warranty - parts on back order) so I'll get it MOT'd/checked out then.

+1, 100% agree

Audi were doing a free MOT and health check last year.
Mine used to create a smokescreen if I'd not left the city for a few weeks and then opened it up on the motorway.
Not sure how normal that was.

Dont panic!!!! Talk it to dealers for piece of mind but believe me this is normal.

MInes smokes like a beagal...sometimes on hard accelaration and very badly when shes been stood for a few days.

They burn oil like theres no tommorow.

I use a litre every 800 to 1000 miles no problem.And i aint the only one.

Apparently its a characteristic of these engines.

another +1

I get puffs but tends to be when cold or when unused for a bit

although I get a lot more miles between oild top-ups than that ^^^
