Hi everyone,

What is the EPC light means

I just had my EPC light on on my dashboard this afternoon, but the lupo was running ok, it didn't look like it had any problems.

I've checked from somewhere else from internet, they said maybe is the break light problem or any sort of electronic problems

I just upgraded my alarm to cat 1 alarm 2 mothns ago.

please help me, with many thanks.

If it's the EPC light by far the likeliest fault is the brake switch. And it's lovely and easy to diagnose - press the brake pedal and get a mate to tell you if the brake lights are coming on.

Other possibilities include clutch switch and some other more unlikely stuff, but you'd really need to know the fault code to diagnose them. Brake switch is the common failure point.

Electronic pedal control.

Could be a dodgy accelerator pedal position sensor, or possibly something related to the throttle body.

Bear in mind it probably won't go out straight away even if you fix the problem.

I had it on before and i lost power at the same time. Think it was a iffy connection on the throttle body. Fingers crossed it aint happened since.

get some electrical contact cleaner for the connection to the throttle body, give it a good squirt (what a word) then get some silicone spray grease and put some on the connection, then plug it back into the throttle body.

Should hopefully cure it.

Time for another hijack!

EPC has been on and off since the day i bought the car but the brake lights always work. about a month ago i drove to work in heavy rain, the car decided 20 mins form work to drop power. turned her on then off then she worked. took ehr to a VW specialist and the couldnt find anything wrong? 50 quid down. shes been driving fine for a month now but my car now for some reason, has decided to limit me to 2000rpm again. been like this for days. initially i thought it must be because of the wet weather, but now the weather is fine and car is still griefing me. even troubling to start up. the EPC light drops on and off quickly and the revs change in my car. i took my air filter off looked into the throttle body and the butterfly valve is just staying shut even when i rev? im fed up now! been three days!

yesterday after sitting revving the epc light went off and it revved. i drove it for about 5 mins then the power loss again. im going to buy som electra clean. see if the ****er will work for me :(

anyone else suffered this bad form the issue?
