Help me Audi A3 mk1 1.8turbo

[Leeberto73]

Hello can anyone help me I'm looking for a cam sensor and boost pressure valve there the engine codes I am being given once these are fixed will I have full boost and ATM feels like a coil pack the way it's Juderimg and turbo feels blocked will these two problems fix it

What are the actual fault codes? your descriptions are too ambiguous

As its mk1, i presume it's AGU engine. It will be a Maf, N75 valve, or Ignition amplifier i had to buy all 3 over time.

Hi sorry for late reply it's the Agu engine and my fault does are
17513
17608
17524
17522
16396
17511
Most codes are saying lamba sensor but I have straight decate on my car

17513
17608
17524
17522
16396
17511

These are the codes I'm getting

For future reference you can get code descriptions here... doesn't cover all unfortunately but get a decent idea of whats going on

Posting descriptions helps anyone looking at this post too as it means they don't have to spend the time searching for you...

Anyhoo...

17513 - Can't find this in the wiki but google returned "17513 - Oxygen (Lambda) Sensor Heating; B1 S2; Heating Circuit P1105 - 35-10 - Short to Plus - Intermittent"
This is related to the post cat lambda and suggests a faulty sensor or wiring

17608/P1200/004608 - Boost Pressure Control Valve (N249): Mechanical Malfunction
http://wiki.ross-tech.com/wiki/index.php/17608/P1200/004608

This suggests you have done an N249 bypass or have a faulty DV... its symptomatic of an overboost or other issue where the ECU needs to shut the boost off to prevent engine damage... if you have an N249 bypass then you will need to log boost... I would not worry too much about this one until the other faults are sorted..

17524/P1116/004374 - Oxygen (Lambda) Sensor Heating Bank 1 Sensor 1: Open Circuit
http://wiki.ross-tech.com/wiki/index.php/17524/P1116/004374

Basically precat lambda is unplugged, faulty, wiring faulty or fuse blown

17522/P1114 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High
http://wiki.ross-tech.com/wiki/index.php/17522/P1114
More than likely related to the 17513 fault...

16396/P0012/000018 - Bank 1: Camshaft A (Intake): Advance Setpoint not Reached (Over-Retarded)
http://wiki.ross-tech.com/wiki/index.php/16396/P0012/000018

What year is your car?... you say its an AGU engine but this code suggests it used to be an AUM... this code is for the VVT cam chain tensioner... AGU doesn't have one... if its an engine swap then I'd check they fitted the VVT tensioner... else if they have then the tensioner is either faulty (most likely) or its oil pressure related..

17511/P1103/004355 - Oxygen (Lambda) Sensor Heating; B1 S1: Performance too Low
http://wiki.ross-tech.com/wiki/index.php/17511/P1103/004355

Precat lambda... probably related to the 17524 code...

You basically need to sort these issues out...

Hi yes sorry it's a aum engine it's a 2001
I'm going to replace the cam shaft sensor and looking on getting it remapped to delete the lamba sensor
Not to sure about the bypass I will contact the person who i got it off and ask them about it

 

[<tuffty/>]

Its not the cam shaft sensor dude.. that fault is because the VVT tensioner isn't working properly (or in the case of an AGU non existent!)... you need to check firstly if the VVT tensioner is fitted... if so then it probably needs replacing..

You can only realistically code out certain codes (normally the CAT efficiency) for the post cat lambda... normally needs to be electrically connected so that emissions readiness is reported to the ECU else fuel trim adaptions won't work.

Main issue is the pre cat lambda... this is essential for the ECU in controlling fuelling and is most likely the cause of the poor running...

A remap will NOT fix these issues... these need fixing before getting a remap...
