REGARDING SKODA OCTAVIA VRS GASOLINE

[huzzen27]

Hi group,
I have one problem in the skoda vrs with turbo engine,vehicles starts but not accelerates and EPS light does not erase,i think throttle body does not get proper spark or current so it does not let the vehicle accelerates,its vag ecu number is-06A.906.032,Bosch ecu number-0 261 208 532, main mcu infineon -B59388-1037362038,95040 eeprom in the ecu,can anybody solve the problem,thanks and regards-Huzefa.

Hi, have seen a few esp light problems, but not normally linked to engine problems,
the usual fault code we had was G201, which is a brake light switch issue, that is possibly the sender on the brake master cylinder,
It can me replacing abs hydraulic pump,and thats expensive

you can reach the plug for esp light behind ashtray if you need to turn out.....

As for loss of engine power, check for split in hoses, loss of vacuum,
can cause car to run without revving over 2,500 rpm,

Good luck..

I think you mean EPC lamp (electronic power control) which cause such problem. Is it correct?

yes you are right man,any solution

[wizz2c]

have you read fault codes?

[Alex789]

yes you are right man,any solution

If you have VAG-COM (VCDS), you can read engine (01) measuring blocks (08) channel 62 and check if, while pressing accelerator, all 4 fields change evenly.

1 Throttle valve angle 1 G187 %
2 Throttle valve angle 2 G188 %
3 Accelerator position sender 1 G79 %,
4 Accelerator position sender 2 G185 %

When you find that any value remains steady. it means that this circuit is broken. Check connectors, wires or potentiometers in throttle body or in accelerator pedal accordingly.

Sometimes wire in throttle body (silver colour) between connector and PCB lost contact.

Hi,

I am having problem.

Cars key is ON but not running.
On block 060
1 Throttle valve angle 1 G187 %
2 Throttle valve angle 2 G188 % --------> In this the value keeps changing between XX.9 and XX.3
3 Accelerator position sender 1 G79 %,
4 Accelerator position sender 2 G185 %

Done the TBA but still keep changing.The RMP changes 670 to 680.

Pls help what could be the problem??

[Alex789]

What does it mean "XX.9 and XX.3" ? There should be figures.

[alexs307]

what are the fault codes? If any code is related to a internal module checksum error, you need factory ecu upgrade.

[vrspower]

Sorry for the delay.

VCDS - On block 060 (Key on but engine not started)
1 Throttle valve angle 1 G187 % 14.5%
2 Throttle valve angle 2 G188 % --------> In this the value keeps changing between 85.5%, 85.8%
3 Throttle adaption steps 0
4 Result
throttle vale adp ADP.OK

Not fault codes.The only problem is the RPM changes from 620,670.

MAF perfect
Coilpack perfect
No vac leak

[Alex789]

This value should drop to approx. 3-5%. The problem lies in this circuit. Check wiring from ECU to throttle body and check/clean appropriate pins of connectors. If you will not find the problem, open throttle body and check it inside.
Usually, in such case, there should be fault code. Maybe immo in ECU is switched off and it don't show DTC at all.

[Alex789]

In addition:
1. Emergency idle mode will be used when both potentiometers in throttle body G187 and G188 are defective. I think, in your case, G188 has open circuit constantly and G187 sporadically.
2. DTC table is, probably, switched off. Disconnect, for example, MAF and check if trouble code appears in ECU.

Have you measured yet the battery and checked the body earth. A bad battery and a bad earth bring you a lot of problems. Check these ones for first than try to make auto adaptions of the throttle.
Hope it helps
