Hi.

I wonder if someone can help me decipher code P0420.

I also have codes P0118, P0106 and P0170 at the same time. All in all I cannot accelerate without the engine losing power and the yellow lamps are turned on.

The motorlamp is constantly shining as the EPC and servo one can be more varied.

Thankful for input and thoughts as I believe these codes can be a combo of sorts and I would like to find the major issue.

Thanks in advance.

Hello Housebengt,

 

I don't think your handheld code scanner is quite up to the job of diagnosing the trouble. The car has obviously got so out of order that the on-board computer is lighting warning lamps but the hand held scanner does not give enough detail.

 

I'd recommend downloading a copy of VCDS-lite software (for Windows) from Ross-Tech and registering and buying a licence (about US$100) and buying an OBDII to USB adapter from Amazon or somewhere similar (about £20 or so). VCDS-lite is old software but is good for VW based cars up to 2004 - so it should be fine for your 2003 Fabia.

 

I've certainly noticed that my handheld scanner does not tell me about 'intermittent' problems which are detected by and stored in the on-board computer. So, no warning lights and nothing on the handheld scanner, but VCDS-lite reported a couple of 'intermittent' faults.

 

People here will also need to know more detail about your car before they can help much. There should be an information label in the boot/trunk with 'PR' codes for the most important options originally built into your car; engine and gearbox type and type of brakes etc. For this fault people will need to know the engine codes at least. It would probably help to know how many kilometres it's done and whether (if you know) it's been fully maintained and serviced during its lifetime.

 

 

 

Thank you kindly for your advice. I have an appointment at my carshop tomorrow and I hope they will find a solution. Best regards, Bengt
