EPC light on and accelerator not working

[Rik N.I.]

As above fault code

17967 - Throttle Valve Control part (J338) Fault in basis settings
P1559 - 35-00 - -

Car is idling like a tractor, poping and farting away.

Any ideas what this could be, sounds like the obvious throttle body, anyway of confirming this apart from buying a new one obviously? If it i sthe throttle body is there much work involved and are they pricey?

Fault wont clear on Vagcom nor when I reset Ecu.

All help appreciated

Thanks

Rik

Check

and do a throttle body adaptation

(disconnecting battery in order to reset whatever you were resetting is not the same as doing a TBA)

then post back if no joy?

Thanks mate, got a lift to work, will try when I get home.

My brake pedal is also rock hard even tho I haven't used the brakes? Not sure why that is, been told by someone else it could be my airflow meter?

Gotta say I can't see your brake pedal issue being related to your MAF, did they elaborate?

I would say it's worth checking your brake servo vac hose, which in my case split when i was driving and caused the pedal to feel hard (as the servo was no longer helping me brake)

On the throttle body subject, I can't find a guide or link but cleaning it with carb cleaner may be the next step.

Went to do this lastnight and the measuring block just said error, so left it in with the dealer this morning

 

[karl.w]

did you have a look at the throttle body to see if it's sticking or not working at all

 

[Rik N.I.]

Trying it now mate just looking a guide to cleaning it lol

Ecu looks like alot of water has been round it so gona get a guide for taking it out to and try to dry it

 

[Rik N.I.]

Should the throttle body be stiff? I thought I would have been able to spin it round with my finger? Car is off and I've set something on the accelerator pedal so it is now fully in, should that turn the body round? Trying to clean the other side

It seems stuck? But maybe it should be like that with the car off, I'm not sure?

 

[karl.w]

not sure you could try to realign it using block 60 on vag-com while the intercooler hose is off and have a look and see if it moves

 

[Rik N.I.]

Vagcom just says error for that measuring block, need to try another throttle body to eliminate that problem

Much work involved in changing these?

It should be stiff i would have thought as its electronic so its the motor your turning not just a butterfly flap.

 

[Rik N.I.]

It wont re-align karl, would hear it, and vagcom doesn't even try it just says error

 

[Rik N.I.]

Ok cleaned the throttle body out and all is fine, car running great and brakes are back to normal

But traction control light is on and so is the EPC light.

Car is still throwing up the fault

17967 - Throttle Valve Control part (J338) Fault in basis settings
P1559 - 35-00 - -

and another fault 01314 Electronic Control Module

None of this will clear, gona drive the car for a while and see how it goes

 

[cupra_matt]

Sounds like a connection problem to me.

I had similar issues on mine, remove the large plug on the engine ecu and clean it with some electrical contact cleaner, refit and re align throttle body.

 

[Rik N.I.]

Car is still driving fine, sometimes when I start it epc and traction light come on sometimes it doesn't

Electronic fault is now cleared, but may be back up have to check

Its channel 60 to do the re-alignment right? Should meas block 4 say Error? Also when I go to readiness and group 60, its says group 60 not available?

 

[cupra_matt]

you need to go to "basic settings" channel 60.

 

[Rik N.I.]

Yea done that a few times, but should measuring block 4 say error?

 

[ibizacupra]

if battery voltage is low it can fault like this also I've seen.

 

[Rik N.I.]

Went for a good drive lastnight, so battery is well charged and Epc has stayed off allday after being started about 6 times.

So hopefully the problems are all sorted, will try vagcom again now that battery is definately well charged.

Altho I was suprised at just how stuck the throttle body got, took half a tin of wd40 then carb cleaner and about 20 min with a screwdriver to budge it, was completely solid
