EPC light?! Skoda Fabia 1.2 2003 mod

[Torbo]

New experience today. The EPC lamp started to light after I struggled to get the car off of the snow as it was a lot of today. Much use of itch and gives to get it loose. Some ideas about what I can do? Diagnosis? Snow in a cable? I think I will go out soon and delete the fault code, if possible? What else can I do?

 

 

The manual: 

EPC fault light  (petrol engine)

The  (Electronic Power Control) warning light comes on for a few seconds when

the ignition is switched on.

There is a system fault in the engine control system if the warning light  does not

go out or comes on or flashes while driving. The engine management system

selects an emergency programme which enables you to drive to the nearest

specialist garage by adopting a gentle style of driving.

ENGINE WORKSHOP! (ENGINE FAULT - WORKSHOP!)

Check to see if your brake lights are still working correctly.

If it's not that I'd bet on a coilpack failing.

VCDS read for codes.

Thanks!

I will read codes first. I bought a new coil pack for some other reason, ... So may be?

 

My be change spark plugs also ca be a good idea?

 

The cold start vas no good to day. Normaly I can drive right after start to get normal drive and temperature. To day much off snow, high snow edges and may be snow on exhaust systems and water vapor and therefore faulting on lambda sensors? 

 

The m´lambda sensor S1, before catalyst is very unstable on my car. I have changed sensor twise, and I will try again. 

Working a while an so on... My be the catalyst is bad?

A little more concrete. New diagnosis noted: 16514 S1 P0130. Erase the code, but both EPC and engine light came back after a few km. Put the car inside the garage at work during the day for thawing - worming. At the end of the day, I disconnected the battery and put on the parking light switch and ceiling light ("butter on the bottle") to completely drain the computer for power supplies in capacitors, etc. - to reset the memory completely (if possible).

Since I had a new lambda sensor, I mounted this on the manifold before the catalyst.

Ready for a new diagnosis and suddenly there were no error messages! Started up and drove home. Now I have the hope that error codes do not show up again !?

The idea of emptying the system completely for power is that the EPC control is superior, so when there are a lot of engine lights and errors that have been erased, this controller has thought that "enough is enough" and therefore the car must at the workshop. ?

There were some thoughts, maybe someone can tell me more about this?

Has a suspicion of "wear" on the catalytic converter too, as the engine used a lot of oil earlier.

Now it hardly spends what a normal engine needs to survive.

Expects to change registry drives after 100,000 - 120,000 km from now.

Just cross your fingers and hope that the car goes "painlessly" in the future.

 

By the way, tried a tank with 98 octane gasoline. It gave no or worse effect. ! Thought the computer was so clever that it added a little more excitement and would give more engine power? But apparently it was not programmed in this "simple" computer. Believe me or not, it went worse and it was after this engine light came on etc ..

Some may argue that this was a coincidence or an indication of the engine power? But I imagine that 98 octane gasoline has longer burn time to avoid detonation. Do not claim anything, as there are experts in here who know more about modern engines than me. May well call these registrations ... All the explanations do not have me.

Thinking back in the 1970s, as outboard engines went better on the lava field than higher octane, then there was mechanical ignition adjustment and it was not a pleasure that the ignition timing could be increased to get more out of high octane gasoline. (not then either). According to Statoil, the amount of energy is the same in 95 and 98 octane gasoline today.

I drive a lot to day, and the engine run good, no fault light!
