    after driving for about 5 minutes the kick down stops working and the engine will not go over 3000rpm even in neutral. If I stop and restart the engine everything is fine for another 5 minutes. Mercedes have changed the Air Mass system, cat converters and fuel filters but problem is still there.

There can be an array of problems that can illuminate the EPC lamp on S-Class 220. A few of the most common faults with these are : HFM sensor, turbo or blocked cats. the best way to check the cats are the remove them and tap them on the ground and if dust falls out then the cats are damaged, if OK, you may have to plug into a diagnostic machine.
let me know how you get on,

WHAT DOES EPC STAND FOR ?


"Engineering, Procurement, and Construction" (EPC) is a particular form of contracting arrangement used in some industries where the EPC Contractor is made responsible for all the activities from design, procurement, construction, to commissioning and handover of the project to the End-User or Owner.

In case of cars:
The EPC indicator is a standard in Volkswagen and Audi models. These vehicles have drive-by-wire systems that are computer-controlled. When a fault exists with the throttle pedal, throttle body, traction control and cruise control, the EPC warning light illuminates. In many instances, the vehicle's throttle may be limited when this light is illuminated in order to protect the engine. Often, there is just enough power enough to get the vehicle to a service facility for repairs.

I have a 2006 Polo Classic & noticed my EPC light


Hello
The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Epc


EPC stands for Electronic Power Control and it means that there is something wrong with your cars electronic systems. This could be a serious problem with one of your cars systems or could be as simple as bad wiring (especially if your car has any added after-market components).

My f350 w/v10 has a serious loss of power from a standstill. The engine will bog down when in forward gear. In reverse, I can spin the duallys. In park or neutral the engine seems to have plenty of hp. ...


You can spin the duallys in reverse because reverse is a MUCH lower gear. NO, there is no kickdown cable for your transmission. Your transmission is controlled electronically.
If the engine is bogging down or if the transmission is trying to start up in the wrong gear, either the check engine light should be on or the O/D OFF light should be flashing. The best course of action in diagnosing a problem with a computer controlled engine and transmission is to scan the computers that control them to check for fault codes.

Epc light on


EPC means Electronic Power Control.

When this light comes on, yopu could have such a sudden power loss.

However, before visiting a workshop for help, do the following basic checks:

No air leak into the intake system.

Ensure that all the electrical socket in the engine management system are well fitted, no loose contacts.

This light can be caused throttle valve malfunction, MAF, brake lights, EVAP , 02 sensor, secondary air pump.

I suggest you visit a competent dealer or independent shop for help. They will scan the EPC and run 'Throttle Body Adaption'. and diagnos the problem. Ask for a garage with a 'Ross Tech VAG-COM' or a ' VW diagnostics scanner.'

WHAT'S EPC MEANS ON THE DASHBOARD


EPC = Engine Power Control it's the engine control module yellow warning light.
You need access and erase the EPC memory by DTC (Diagnostic Trouble Codes) using diagnostic equipment connected to the data link connector of the car, in order to reset the EPC, and turn off the EPC yellow light.

Epc on


The EPC light is the Electronic pedal control. The mass air meter, brake switch, the throttle body, the gas pedal, wiring, and the computer all are tied to the EPC light. If you had a EPC or the engine light on then there is a fault. This can cause the computer to enter a limp mode or the improper signal is sent from the accelerator which manifests itself as poor performance. There have been some recalls on this so I would visit your local VW dealer.
