    Car problems after re-map! HELP!!

    Ok so I have just had my s3 8p remapped and for the first day it was beautiful, smooth all way up to redline. Second day I took it out for a spin and again beautiful at low revs but when I put my foot down and the car got to around 5000rpm the power just died! The whole car jults and the revs return to normal. It's as if the car runs out of fuel at 5000rpm and above. Again the car is fine through te gears and even when you floor it it's nice up to 5000rpm then dies and returns to normal!

    I have aves spoken to the guy who remapped it and he said it was a common problem on the 1.8T previous but never heard of it in the 2.0l 8p!

    Any ideas???

    Check / change your plugs - they tend not to last more than 10k.

    As nluk100 says,check/replace the plugs first.

    After that,coil packs are another weak point.

    Which company did you use,and what software?

    I used a local tuning garage and they are Quantum remap dealers. He has said it might be the turbo pipe collapsing?

    is that a possibility?

    It's remotely possible,but frankly unlikely.

    I've not seen that happen,even on mine.

    More likely are the two things above,and what he should do is to log the car under the conditions that are causing the problem.

    Fuelling is another possibility,but logging will show that also.

    IMHO I would say its not the intake pipe collapsing on the 8P 2.0, that was the 1.8t for sure that Forge created the new one for, very well known issue of which I had myself.

    I would also say plugs, coils then map tbh as above, 1st 2 are common as mud.

    Great thanks guys. When you say loggin AlexS3 do you mean when you plug the car in for diagnostics?

    Will that show spark or could issues?

    Plug it into a laptop and take it for a drive whilst collecting data.

    Then review data such as boost fuelling timing etc etc and any fault codes.

    Sounds like a camshaft sensor/engine speed sensor fault.

    I had it recently on my VRS. Changed the sensor and all is well.

    As said, best get the car scanned to be sure.

    Good luck.

    Don't accept it until it's running perfectly,and they do need to log it.

    I think that software and map related issues would be their responsibility,but things like plugs,coilpacks etc and any issues exposed by the map would be yours

    Hi all, me again! Sorry to be a pain. As I said in a previous thread I changed the coilpack and the sparks and all seemed to be ok! SEEMED! Took it out for a spin today and guess what...it's happening again!!! Ahhhhhh! They have turned the map down and reduced the boost, logged the car and the following results shown....

    P1093 = Bank 1 fuel measuring system 2 malfunction
    P000A = Camshaft position slow response
    P0087 = fuel rail/system pressure to low
    P2261 = Turbo boost pressure not detected

    Any ideas!

    Thing is I don't want to just change any probability costing £££££

    How long have you had the car?
    Did it run ok before the map?
    Can they flash the car to standard to see if the car runs ok without the map?
    Looking at your faults I'd be suspecting the map if it ran ok beforehand.

    Yeah they said they can flash the map and return it to standard. I have had the car for around 6 months and it was not doing it b4 the map. Quantum are adamant that it's not a software issue as the faults don't relate to software issue. I am toted to change the camshaft sensor and the fuel sensor to see if that stops it. But again it's just £££. Not really sure what to do. Just remove it?

    I think most of those codes look software related.
    Get them to put it to stock and if the problem persists then change things.
    If it ran ok for months before the map I'm sure it'll run fine once put to standard.

    I would take it off personally, not a vcds person but logs are related to the fuel pump maybe which on stage one you shouldn't need to change. Did they scan the car before mapping it?
    Any tuner should have done that so if not remove map and clear and scan the car for fault codes. some of the more experienced guys may know better as everyone seems to have different ideas on what are the "Stages" good luck though.

    p.s what fuel are you using the good stuff or supermarket stuff

    Supermarket stuff but my m8 gave me a good ear full and now running bp 97. I am almost convinced that it might be the DV. I took it for a spin again earlier and worked fine, floored it and it pulled all the way. On my way home I put my foot down going up a steep hill and guess what....it happened.... Then again going up the next hill. As soon as was on straight it worked. Makes me think pulling the car up the hill with so much boost is blowing the DV valve and stopping power.

    Back in the garage tomorrow with a different garage on a rolling road to determine the issue...hopefully

    No they haven't done that yet. He sent the file back to Quantum and they check the file and fault codes and Quantum have said that the file/map is absolutely fine. They sent back a second map that had the boost turned down.

    I'll be honest, if they can't find any issues tomorrow I will just have Car flashed, get my money back. Just annoying

    Seriously,there has to be a reason for the way the car is behaving.

    If you can get most S3's running Stg2+ software and 360bhp without issues,there is clearly a problem here.

    I'd be tempted to have it removed,get your money back,and take it to a tuner that CAN solve the problem.

    yea might be best to get it get your original software back on there.

    Sounds a bit like fuel cuts stage 2 gti's experience...

    This has turned into a massive nightmare! The car has been in the garage since Tuesday. The ECU has been flashed back to standard and After sticking it on the rolling road the same fault codes showed
    P1903
    P000A
    P0087
    P2261

    They the. Suspected it was the DV valve. So after replacing it with the updated Audi one fitted to the RS models.Then they stick it back on the rolling road and it happened again. He said it's working a lot better now and revving higher but still cutting out. They logged it and now all error codes have gone except 1 P1903 = bank 1 fuel measuring system 2 malfunction!!

    now they are completely stumped! The mechanic seems to think its still the map and it might be lingering or mesas the ECU up.

    Is this possible? The only way to make sure for good is to get Audi to put the original software back on but don't know of they would do that??

    Does anyone have any experience or advice with the above fault code?

    Not sure what to do now

    I still think you need to change/check the camshaft sensor, with the symptoms your are having, they would lead me to that. I changed the cam follower, fuel filter and checked the DV, but still did it. Changed the camshaft sensor and fixed it straight away. It's £120, but cheaper than some of the other options.

    Is the camshaft sensor the same as the camshaft position sensor as that's all I can find?

    It's also known as the engine speed sensor.

    Hi Rog

    Sorry to be a pain. Do you know what one I need as there are 2

    Hi Harvey,

    What I think you need is this, Camshaft/Crankshaft position sensor.

    Link below

    Audi | Euro Car Parts UK’s No.1 Car Parts Retailer

    I wouldn't trust the ones on eBay, you better off going to TPS or a dealer for the genuine part. Not cheap, but worth it.
    Having said that, the one on ECP looks ok.

    The Audi part number I used is :06A 906 433L

    There is some confusion, as the part name seems to change from place to place!

    But this is what I had changed and it sorted the problem. I hope it does for you mate.

    You may want to double check the part number for the S3, it maybe different?

    HTH

    Sorry to hear that.

    You do need a tuner who can just work the problem until it's solved.

    AMDTuning spent a lot of time tracking down a very odd fault on mine and along the way found a dirty MAF,faulty thermostat and a couple of other bits before the final issue was a faulty throttle body.

    Often,it's not just one thing.

    Sorry that didn't work out, They did change the correct sensor, didn't they? It's the Crankshaft sensor, not camshaft. Located under the engine, next to the oil filter? It's a pig to get at!

    You may want to confirm that they did the right sensor.

    If they have, then I'm stumped to be honest, what it could be.

    Good result.

    Does show however that these engines are pigs to sort if one simple sensor decides to chuck in the towel.
