taffyboyo Posted May 4, 2006 Report Share Posted May 4, 2006 since the intercooler hose came off whilst driving last week, the car (2004 a4 avant) has not been driving quite right, there is now a lot more black smoke coming out the back and the throttle seems to be a little hesitant and it just doesnt feel right, this is the second time the engine warning light has come on so there must be something wrong with it, the dealer just corrected the warning light and not the actual fault (at a cost of £116 to me) they said they couldnt rectify it cause they couldnt find out what was wrong because the car has been chipped.(revo) I'm now waiting for a sps1 to arrive by post, should be tomorrow and then change it back to stock and then take it to a different dealer in order to find out what the problem is. anyone have an idea what could be the problem beforehand? or advice ref the car? many thanks Taff ps sorry about the story Link to comment Share on other sites More sharing options...
UBM Posted May 4, 2006 Report Share Posted May 4, 2006 Sounds like it is overfuelling to me - hence the black smoke. Once you have the stock settings back then drive it for a few hours to get it to settle down again. Link to comment Share on other sites More sharing options...
kite Posted May 5, 2006 Report Share Posted May 5, 2006 Could be a MAF problem ! Link to comment Share on other sites More sharing options...
taffyboyo Posted May 5, 2006 Author Report Share Posted May 5, 2006 cheers, does anyone think that the intercooler pipe coming off cause any lasting damage, when it happend there was loads and loads of black smoke and loss of power and it was making like a droning noise, and it hasnt been right since Link to comment Share on other sites More sharing options...
taffyboyo Posted May 6, 2006 Author Report Share Posted May 6, 2006 sps1 arrived this morning, worked a treat, car now back to standard, quite suprised really as it now drives a bit smoother,the revo map is a lot more aggresive but the surge you get makes up for it and there isnt as much smoke chugging out the back, got it booked in next week so will put the performance map back on after a trip to the garage.

Lynas Posted May 6, 2006 Report Share Posted May 6, 2006 Try it until the black smoke vanishes and the ECU resets to normal running and then map it back to REVO. If you get the black smoke back.. well, there's something not happy somewhere. If not, then bonus, Link to comment Share on other sites More sharing options...
taffyboyo Posted May 6, 2006 Author Report Share Posted May 6, 2006 the car still feels like its holding back when going at a constant speed, I'll leave it standard and wait untill audi have looked at it, and if they fix or replace something, I'll switch it back for the drive home:) Link to comment Share on other sites More sharing options...
UBM Posted May 7, 2006 Report Share Posted May 7, 2006 Would it be a turbo lag you could describe it as? Link to comment Share on other sites More sharing options...
taffyboyo Posted May 7, 2006 Author Report Share Posted May 7, 2006 UBM, no mate, it feels like this in any gear with all the rev range, its hard to explain really-put your foot down it feels ok, take your foot off it feels ok, its just in between thats the problem Taff Link to comment Share on other sites More sharing options...
taffyboyo Posted May 9, 2006 Author Report Share Posted May 9, 2006 right then just got back from dealer; turned out the air mass thingy needed replacing, then on way home the engine light came on again this turned out to be a seal on the turbo (hence the black smoke) all ok now (hopefully) I'm going to leave it for a while before I switch it back to the revo map, because after the first visit today I switched it back to performance and the light came on again, I think this was just a coincidence because there was still a lot of smoke coming out the back, driving away from the dealers, before the engine light came on again, fingers crossed all sorted now cheers Taff Link to comment Share on other sites More sharing options...
