Its time again for another monthly problem with my S3.........
Right, after my negative intro.... I have been searching for info on this but I have a few problems that im wondering if they are related. I'll give the whole story for all you 1.8t detectives out there :thumbsup:
Last month, I had to fit a new head as mine was cracked, fitted the head and new cam belt etc but couldnt get the exhast manifold to stop blowing between that and the turbo. It had a new gasket and after a day of trying, I decided to tighten the new bolts further than the torque specified.... worked fine and I finally got it sealed.
Now its back on the road, I have noticed the temp guage never goes to the middle like it used to, its a 6 month old audi green top so dont think its the sensor, it always sits on the white dash to the left of the center one.
Im sure also the car seems hotter and the mani glows more often than it used to, what do I need to do to check the EGTs? I have vagcom but im not exactly a pro with it yet!
Even worse now is the fact I drove for 300 miles at about 80 and had a return of 27.3 mpg which is dire, when I do this run normally, its always over 30mpg even if I put my foot down a few times. I had to drive conservatively to get the mpg a bit better. Then finally on my return 300 mile journey, I put my foot down in 6th to overtake and as soon as it boosted, it really miss fired and shook the engine about a bit. Now, since then, I have had misses all through the revs after 2.5k
Thanks for any help, you are all probably getting familiar with my constant 'my s3 is broke' threads, I dont think I would have my car if it wasnt for all the help from you lot as garage fees aren't finacially an option for me at the moment, so thanks again for all the help, James
