Several Faults........

[Ninj]

A friend has been having problems with an Audi TT and has the following fault codes:

7 Faults Found:

17704 - Error in Mapped Cooling System (usually temp Sensor or Thermostat)

P1296 - 35-00 - -

17584 - Bank1: O2S (Lambda) Correction Behind Catalyst: Control Limit Reached

P1176 - 35-00 - -

16684 - Random/Multiple Cylinder Misfire Detected

P0300 - 35-10 - - - Intermittent

16687 - Cylinder 3 Misfire Detected

P0303 - 35-10 - - - Intermittent

16686 - Cylinder 2 Misfire Detected

P0302 - 35-10 - - - Intermittent

16685 - Cylinder 1 Misfire Detected

P0301 - 35-10 - - - Intermittent

16688 - Cylinder 4 Misfire Detected

P0304 - 35-10 - - - Intermittent

The car is standard incidentally.

The 17704 comes on almost straight away but the misfire codes are only when the cars been driven for a bit.

Reckon a new green temp sensor will clear the 17704? Does anyone have a part number?

Is it 030 and 036 which test the 02 sensor? What values are we looking for?

Is it possible the codes are linked?

What about the coil packs?

[ric04vrs]

if its had a misfire for a long time it could of wrecked the cat , that maybe why the O2 sensor code is there

[Ninj]

I thought about the coil packs but is it not a bit unlikely for all 4 to fail simulatneously?

Yes I guess if the mis was that bad the cat could be damaged, does anyone have any figures to compare to and well run a check

If it's like most of the other VAG group motors the engine electrics will be connected by a large black round plug. I have seen these with water ingress before.
