Dear All,
Firstly, hello, been lurking on the forum for some time as my partner decided she wanted an S3. Ended up getting a 1999 Imola Yellow example - nice spec with heated seats, sunroof and a few other goodies - bodywork in immaculate condition.
My brother owns a remapped W plate S3 which is quite rapid, I didn't know what to expect from a standard one.
We test drove the one we bought and I felt it was a little sluggish albeit we travelled the 400 mile round trip journey in my remapped 300bhp Mk5 Golf GTi Edition 30, so things do tend to feel a little slower in comparison to that ... I also put it down to haldex etc etc - but what a fab car !
A friend has vagcom ... we took to him and it was getting 0 readings of the maf in addition to the below fault codes :-
Chassis Type: 8L - Audi A3/S3
Scan: 01,02,03,08,15,17,22,35,37,45,54,55,56
Address 01 -------------------------------------------------------
Controller: 8L0 906 018 K
Component: 1.8L R4/5VT 0002
Coding: 05610
Shop #: WSC 06313
6 Faults Found:
18010 - Power Supply Terminal 30: Voltage too Low
P1602 - 35-10 - - - Intermittent
16795 - Secondary Air Injection System: Incorrect Flow Detected
P0411 - 35-10 - - - Intermittent
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-00 - -
17978 - Engine Start Blocked by Immobilizer
P1570 - 35-10 - - - Intermittent
17840 - Secondary Air Injection Solenoid Valve (N112): Open Circuit
P1432 - 35-10 - - - Intermittent
17695 - Boost Pressure Control Valve (N249): Open Circuit
P1287 - 35-10 - - - Intermittent
Readiness: 0000 0000
We soon worked out that the maf was not plugged in - a little strang I thought thinking maybe had either forgotten to clip it back in after the recent service or .... that someone had disconnected it as the sensor was bad and the car went better without it plugged in ???
Anyway, that was plugged in - I changed the diverter valve as a precaution (as I believe she will have it remapped soon) - been out tonight - done some logs and .... errr .... not sure :-
Things have noticed tonight :-
According to ross techs 120 measuring block graph it is doing 170.7 bhp at 6600 rpm's with 182 ft/lb coming in at 2700 rpm's, MAF sensor says maximum flow is at circa 6000 with 146 g/s - this must be way to low ? Have also noticed that from the first above run seemed to have lost 2psi of boost - must be my shoddy fitting of the new d.v. will check that tomorrow. Here is the run from tonight (first above run conducted with Tesco 99, this one tonight with Texaco 97 Super Unleaded) - wonder if that accounts for the boost dropping off ??
I will try to clean the MAF tomorrow - but failing any improvement will buy a new one. No fault codes have come back - here is the log from tonight. I also thought that 9/10 psi of boost was a little wimpy - is this normal - it is punching just above requested boost though ?
Have never had a 1.8T before and really do not know my way around these engines am tryong to apply my basic knowledge of the TFSI to the 1.8T and seem to be failing - what do you guys think re the logs ? Am I just worrying because of the MAF ?
Do I have a similar problem to this gentelman's thread ?

Any help would be greatly appreciated,
