    MRC Tuning company

    IMO, this isn't true. The ECU is able to cope with adverse environmental conditions and poorer fuel - it doesn't have much scope to advance timing on race gas for example. Believe it or not, there is still a lot of variation in what various cars and engines will do (mileage does have an...

    Running lean!!!

    Really? The free VAGCOM version now lets you log all the groups and interprets all the fault codes for you?. As far as I am aware, only the full version is of any use for diagnosing this type of problem. The "specialist" you anecdotally refer to sounds more like a dealer to me ;-). I...

    Running lean!!!

    If you have access to VAGCOM then yes, you can do some of the research yourself. However, without access to the diagnostics and the ability to do sensor logging you are just guessing. I don't think 49+VAT is that steep to have someone who really knows what they are doing look over the car.

    Mate, I'd just take it to MRC - they do a health check to diagnose exactly this sort of problem.

    S4: 350 miles on 55 litres

    I never said I put 62 litres in, just going off what it says in the book. The most I have ever put in was 56 litres which was yesterday - 63 quid, ouch!!. This is fettling the clit as well. My dis shows 14.2 average at the minute. I used to get a lot more out before I went K04 and 630cc...

    S4: 350 miles on 55 litres

    S4 tank is 62 litres. I am very fortunate to get over 15mpg in mine. 190 - 210 per fill up :-(

    S4 running bit flat......

    They are both accessible with the right tools. You need an O2 socket (and a crows foot for good measure) - they have a slot for the wire. It also helps to have a 'wiggle' socket set - don't know what the professionals would call it! ;-). I've done both without breaking anything and if I can...

    Don't know where you are in the UK but I'd get it to MRC for a health check.

    S4 EGT Sensor

    You might want to check the fueling. I know you get overfueling with a bad EGT, perhaps you get throttle cut as well?

    My S4 Power :)

    Looks fine to me. The scales are funky, not the numbers. Most places use the same scale. The peak is probably from overboost which all these ECUs have - supposed to give you a bit more grunt for overtaking. Doesn't work in my car, just makes it sound like an asthmatic pig having a ****.

    Audi S4 springs

    We don't really know what has been quoted. I still think 240 for changing all four springs is a good rate. It can be a total ******* if bolts are seized etc.

    Audi S4 springs

    You don't have to undo the pinch bolt if you are just replacing springs on an S4. You can just drop the strut out by undoing the two 13mm nuts which hold the strut to the camber plate. It takes a bit of wiggling but it is possible. I'd only touch the pinch bolt if I was doing the upper control...

    RS4 intercoolers

    The RS4 IC outlets (upper and lower) require 2.5" ID piping. The offside lower charge pipe is also different on the RS4 (longer). See my thread in the classifieds for more details :-)

    Hope that 20 quid doesn't have to go on petrol to get there! ;-)

    RS4 intercoolers

    You don't lose the AC with an FMIC anyway. You lose one very small fan. So far, I haven't noticed any difference.

    RS4 intercoolers

    ICs are fine. Shrouds are cut for fit the S4 bumper profile. You'll need some pipework and the lock carrier will need to be trimmed but that's pretty straight forward - I used a reciprocating saw. The ad is still in the classifieds I think, more detail in there. I fitted a CXRacing FMIC...

    MRC Day :)

    Are you sure it wasn't 1.65 absolute boost (i.e. 0.65 boost above 1.0 atmospheric)? That sounds about right at redline on k03s. MRC maps tend to 1.1 - 1.2 bar (above atmos) at peak.
