so my EPC light has been coming on today putting the car in limp mode, if i turn the car off then turn it back on the EPC light goes away or sometimes the engine management light comes on with the EPC light. Ive done a scan with my ebay obd2 port scanner and it comes up with fault code P2138 this is on my mk2 leon cupra 2.0tfsi. has anyone got any clues? i've looked on rosstech and cant find nothing.

any help would be much appreciated

Is there such a thing as a throttle position sensor on these?
Had an EML on a previous car due to that - and it wasnt a badillion pounds to replace.

My car has this problem. Was more severe before I changed throttle body. Not changed the pedal yet but that's my next port of call. My car is a 2.0tfsi FR

I've also found that a lot of components are found in various other makes and models from across the van range. I've used eBay for my parts

Id get it checked out with VAGCOM to define what is actually wrong, before you start throwing cash at it! As I had an EPC fault and it was because of an out of date ECU file which needed updating, SEAT told me the ECU was f**ked and kindly held out their hands for £1k for an new one.

yes its located in throttle pedal and they don't sell if separate :cry:

Daaayum!

Reminds me when i went to get a plastic headlight rear cover from the Pug parts dept, the guy announced 'That will be £200.00 please' coz they dont come without the actual light cluster unit!!

I've done the vagcom and comes up as throttle position sensor.

I had this coming up on mine a few months back and it turned out to be 2 knackered injectors.

Is the car misfiring before it goes into limp mode???

im still getting this problem. the fault code p2138 even after spending £130 on a new pedal.
this is the wiring how i found it. as you can see the old loom on the right and new loom on the left.
