I have a Skoda Octavia diesel car 2009 model. The vehicle jerks when accelerating. The gets worst if climbing a hill. If acceleration is forced, it will activate the Antilock brake System (ABS) and the Traction Control System (TCS). The fuel filter has been checked and clean as well the air filter. What can be the cause and whats the suggested solution???

What's the engine code?

with your comment on the ABS and TCS kicking in I'm wondering if it might be an ABS sensor issue?

 

Have you had a code reader on it?

The engine code V420 and another number shown on the engine is 038103373R. Please see the picture of the engine and the error light. The issue is this: When i start accelarating, the car will start jerking and will start slowing down and reducing the speed. If I continue to accelerate, forcing the movement, the ABS and TCS light will show up. Once the ABS and TCS light shows up, a warning sound will be heard and from that time, the car will accelerate without jerking but the error light continuously ON. See the pictures

Your engine code is BJB (1.9 PD).

Try switching the ASR/TCS off and see if it makes a difference.

Thanks so much MicMac for the right engine code and for the suggestion. Once the ASR/TCS is switch off, the car starts jerking again.

Does your car have ESP or asr?

 

If it has esp the button will be a skidding car symbol. If it has asr, the button will simply say ASR.

The car to the best of my knowledge does not have ESP which I believe means Electronic Stability Program. However the TCS and ABS light are always on when the car starts jerking.

From what you've described, it sounds like the car is getting a faulty ABS signal from one of the wheels, and it's this that's causing the ABS/TCS system to cut in and out.

 

I had a similar issue with my Octavia when it had an intermittent connection on the ABS wiring. 

 

If it's stopping doing it when the TCS and ABS light are permanently on, then the car has disabled the ABS and will then be ignoring that signal.

 

You really need to get the car scanned with diagnostic equipment to get the fault code.

It could be a number of components that could cause it to have incorrect readings, so a fault read is the best first place to start to get an idea.

 

 

Thank you very much softscoop. I will take the car for scanning and communicate the code.
