iv got these 2 codes
17705
17545
now iv looked on the forum and found these:
17705 P1297 Connection turbocharger - throttle valve pressure hose
17545 P1137 Long Term Fuel Trim Add.Fuel,Bank1 System too Rich
sooo, how do i put them right?
-
clear the codes and re-scan
-
done that
what nxt ?
-
codes still there? if they are then check the throttle valve pressure hose and i dont know about the other 1 sorry as far as i know when vag com shows a fault and you clear it and it comes back then you need to replace that part or have a better look at it.
-
hmm now this is odd, need to scan again. took car out earlier it went into limp mode. no eml tho.
any ideas???

Hi Jase
Is sound like you have an leak air somewhere,
If you have a air leak in the system then the air via the maf reading will be higher than the actaul air getting in to the combustion chamber, the ecu wil give the injection open time for the air via the maf which causes the fuel air ratio to be rich (too much fuel)
The ecu has a lambda mapnbased on engine speed and engine load, to maintain the correct lambda readings the ecu works in a closed loop mode to constantly change the injection timing so the lambda / air fuel ratio is correct.
There is only a set amount the ecu can cut or add fuel and once this limit is reached the ecu will give a fault code as a warning. If you use vagcom and look at blocks 32 you can see the amout of fuel trim the ecu is adding.
If you want you can pop the car over to us and we will carry out a quick smoke test to find out where you lost air is going. Just dont forget the hobnob.. :laugh:

scanned again today. the 17705 still there :sad:
17705 could be related to air intake temps or coolant temps.. :wink:
But is your having a long term fuel trim then I am 99.999% sure its air an air leak somewhere.
