Hello Everybody!

I am new on this forum with my Volvo C30 1.6D from 2009. I bought this car end of last year. A few weeks a go i started getting troubles with the car. I was driving on the high way and it suddenly wouldn't go higher than 3000rpm. After a check with a measurement instrument we learned that we had trouble with the DPF.

I brought it to a specialized garage to get the DPF out of the car and out of the software, this because a new DPF was more expensive.

After all i now have 2 failures in the software and the car suddenly starts to drive again slower till a max of 3000rpm, this was only once and after shutting the car down it worked again well. The failures that the system is giving are:
- A300 ECM Software faulty signal
- DF11 CAN-H high speed network. Signal missing.

Can someone tell me what those failures are and how i can fix it?
is it a result of removing the DPF and software change or is it something else?
On the internet are a lot of failures explained but i can hardly find information on how to fix it.

I hope someone can give me information or put me in the right direction to solve this problems.

 

A300 is expected and should be harmless.
DF11 means that there are issues with CAN bus.
But you don't have any ECM related codes that means you have bad patched firmware.
They cut all codes out from it and now you cannot use diagnostics. I would go to the garage who cut DPF and force them to get this crap read.
