D4 limp mode, but no fault codes??

[Sven94]

On several occasions now my 2010 TDV6 has gone into Limp, with no acceleration just idle. Car can be driven very slowly.. then it just reverts back to normal..
IID tool shows no fault codes.

What is going on here?

thanks Steven

Had similar in my D3. Lost a lot of power but not as bad as you are describing. Didn’t have an IID Tool at that time so don’t know what fault codes if any were thrown up.
Was a sticking wastegate valve.

Your IIDTool probably isn't set-up to see all the codes. I can't remember the option that has to be changed but someone will.

Need to go into the IID settings to show “pending faults”. Google it for more details [emoji106]
