Car in question is a VW Bora 2.0 (not sure on engine code, forgot to check) and the following fault has been plaguing this car for a couple of days now...
1 fault found
17536 fuel trim, bank 1 (mult) system too lean
p1128-35-00
This all came about on Tuesday when i did a scan for him and found two faults pointing towards the throttle body and Lambda sensor.
Cleared the faults, but TBA faults came back.
Found a guide to reset the TBA and both faults went, but the one above replaced them.
The car runs fine when cold, but once its up to temp it idles rough, and stalls more often than not. Smells rich of fuel burning. MPG is barely in the Teens.
Can clear the fault when warm, and it runs fine, but once the engine is off and cooled down the cycle starts again.
Has anyone found a cure for this (i'm sure its not the first time its happened) or got some remedys?
My first guess is a loose hose, or the MAF is dodgy, but before we get the tools out i thought i'd ask some advice.
Cheers for any help in advance :)

Well it hard to say, as they differ compared to 1.8T's.
The maf should be either 1,2 or 3.
Not sure for the lambda, between 30 to 35.
You may want to have a quick flick through
Check the fuel trim on 32
