Ruby Red Audi S2 Avant

[Error404]

Could well be a coil or POS channel. Try and identify the problem cylinder, then you can swap out the spare POS channel and see if that helps.

Thanks Mike just wish i could get driving it again

Heater now works BUT the car is running very rough. Sounds like it's maybe only running on 4 cylinders. I doubt if this is related to the matrix change as the engine isn't touched to change this. Everything else seems to be working.

The red exclamation is flashing on the dash. Will try and get a video uploaded.

I'm away to search the forum for answers. But if anyone has any thoughts please post My initial thoughts are probably a coilpack.

Previoulsly the car was sort of missing when accelerating but not all the time. Maybe this was something on the way out before and now has given up the ghost. I just blamed a boost leak (if in doubt blame it on a boost leak )

Michael I really do like the sight of your car, to think that many moons before you bought her I was about to buy her from Steve, bizarre me thinks and she still looks stunning

Very clean looking car! What kind of heater matrix are you going with? I hear some of the aftermarket ones are junk.

It's been in my boot for so long now i can't remember

Finally getting new heater matrix fitted this week. Been on the to do list for months.

300+ miles to a tank is normal now, so a definite improvement.

Thats what i love about these cars Mike,you can hurtle along at a rate of knots and yet overall the mps are still respectable and up there!

Let's not get carried away, it is all relative.

Also since i changed the Lambda sensor i'd say my mpg is better. Not by a massive amount but the last 2 tanks were 24mpg and 25mpg. This is mostly short drives though. I will post up what my next mpg figure is as it was the Scotland Tour weekend so any guesses to this figure before i fill up?!

I also found this with my S cars, and so I would also definitely recommend one changes the lambda probe with the correct Bosch one ( at 'about' £65.00stg ) you'll still find it is financially well worth while in a pretty short number of fills of the tank.

I might be wrong but i think Macsprings running a 35 profile with his set on his S6?

255/35/18, on Mk1 S8 Avus rims which are 8" x 18 works for me.

8.5" or 9" might be better again, but it I like the S8 rims, and I don't want to have clearance issues. Besides the 255 tyre on the 8J rims means it is much 'harder' to scrape the rim on kerbs. The wider tyre suits the bigger C4 body and also 255 is very hard to unstick.

Mark...tyres are 225/40/18 if i remember right. Goodyear Eagle F1.

I also now run 15mm spacers all round instead of 20mm. Look wise i think 15mm on the back and 20mm front looks best, but i wanted to keep the same size on both axles.

28mpg for the Saturday leg of the recent Scotland tour. Considering the rate of knots we were travelling that's not too bad Saying that i tootled back down the a9 from Inverness at a much slower rate.

Still not washed the car yet

Thanks Mike,i've got myself a set of these now and just need to know the consensus on what size tyre people are running on these. I might be wrong but i think Macsprings running a 35 profile with his set on his S6?

I did notice in the pictures from last septembers epic that the rear wheels stuck out too much and didn't want to say but as you've mentioned it,reducing the rear will look perfect.

As to not washing the car yet .....you naught boy!

Mike,what size tyres are you running?

[John.]

It's a no brainer Anthony,get it done! ..........The love affair goes on Michael. John.........Michael's gonna need all the entry and exit speed his new suspension parts can offer to keep up with a well sorted S6!

Mike knows the score

.....that's why he's not spending money on his S6!
