    am i right in thinking an EGT sensor is around £100? and how many are there on the S4?

    my car is off to PW motorsport next weekend for a health check as ive noticed it aint been running right lately and the EGT is coming up alot from advice on the forums so im thinking it mite need one:( im £60 short of my coilys but they look to be on hold now until i get the car running full health, so if you see my car in audi in the park dont take the piss about the ride height lol

    2 egts, one in each downpipe, think i paid around £140 from Audi and its worth fitting genuines, and if one or both has failed, which is common, you'll def notice a good difference

    S4Twiggy, where you based? I am just off J48 of the M4. My car has been down to Phil several times. He seems to know his stuff.

    I've had my EGTs replaced by Phil, as it happens, and I think they were £120 each at the time.

    Car ran much smoother afterwards. It seemed to stutter before.

    All I got to do now is sort out what's causing the ABS to come on below 20mph. Checked the rolling road speed and that all seems fine. Perhaps I should take it back to Phil!

    both times on mine when a egt went it was around 120 and the boost seemed to hit 10psi and stop dead but all felt smooth . Drivers side you can do yourself i did mine in about 20 mins but passenger side is a bit tricky to get to so is easier on ramps

    like you said mate the car feel smooth but its no kick there, im goint to leave it to phil next weekend as he the professional, i hope he can find the fault an sort it cuz the other day i drove it it felt like a bullet but now its jus smooth, the kick is there but not like it should be. if the EGT was buggered would it make the car stutter like when a lambda sensor is dead

    it must be the EGT then, phil from PW mentioned it after i explained wot was wrong with the car so it must be common for an EGT to make the car feel flat

    Hi Twiggy

    Maybe I'll see you at Phil's on Saturday then, got mine booked in for a MAF replacement about 9.30 - 10am ish, what time you gonna be there?
    Phil seems a top bloke, I popped in to see him last Friday to run the VAG-COM and got EGT and Lambda probe probs as well as the MAF, Phil said start with the MAF as this might cause LAmbda's to f*** up! lol. Could be a costly few weeks for me, I think I'm def in need of EGT's both of em grrrrr.
    I bought the car not knowing what it's full potetial is so will be looking forward to some serious power after all is done.
    One more thing did you know Phil also does remaps? When mine is running well again he is going to put a 6hr trial map on to see what i think.

    When the Bosch MAF fails it normally reads less air volume than what is really going
    in to the engine. This then results in underfueling and a lean mixture which often trips
    )2 sensor codes (execpt short to ground which normally means a fubar sensor).
    Running lean causes high EGT's which result in the engine dumping fuel and restricting
    load. I'd start with replacing the MAF and clearing the codes to see what comes
    back (unless you have short to ground codes).

    Open/short to B+ intermittent is what it says :confused:

    See what happens Saturday when he replaces the MAF fingers crossed that's all it is but knowing my **** luck I'll end up with another £700+ to have to spend on the bloody thing lol!

    If its definately the turbos, you'll here them squeel especially on boost. Need to check if there is bluey colour smoke coming out the exhuast... thats another sign.

    You could be lucky it could just be the DV's being knackered.

    Hope its nothing serious for you though.

    Sounds like you got similar probs to me m8! MAF, Lambda and EGT probs, to top it all my left rear spring bust on me the other night so I'm waiting for a price to get that fixed next week grrrrrr:wtf: oh well it's true what everyone says, these cars cost a small fortune to keep on the road, but hopefully worth it.

    See you Saturday Twiggy mate!!
