can anyone advise us please. We have a Volvo xc40 B4 inscription pro 2021. No issues until 12th April when the vehicle suddenly misfired lost power and went into limp mode for no apparent reason, no warning lights on the dash board. This happened again at high speed a fews after getting the vehicle back from Volvo. The vehicle has now been the Volvo garage 5 times since the 12th April and every occasion they state they cannot do any thing as no fault codes. Another symptom is the vehicle sticking in gear ( it’s automatic) we have had the vehicle on an independent garage computer which showed 8 fault codes at least 3 were relevant according the technician but Volvo say they are not showing on their computer so they cannot act on it and state there are no relevant fault codes. Any advice please greatly accepted as going round in circles thank you

If an independent can see them and the dealer you're going to can't, change to another main dealer.

Get the indi garage to write up their findings and give to Volvo.

Typical main dealer technicians - rely on the diagnostic computer rather than using some mechanical/electrical investigations. They dont want to do anything that an old guy would do for fear the warranty o customer wont pay for their time and parts swapping

We have already taken videos showing all fault codes but they were disregarded as not accurate as not from a Volvo computer. Unfortunately we have gone into limp mode no acceleration and engine cutting out twice today, it is so unsafe but as no fault codes nothing can be done, can’t sell it, can’t use it can’t seem to get anyone to sort it under warranty ,

Forget the fault codes, what does the indi garage reckon the issue is and how to fix it? Armed with that info take the advice of Chris John and go to another Volvo dealer. If no joy go direct to Volvo.

Volvo will disregard indi garage opinions on fault codes. Connection of unauthorized equipment to the car's diagnostic socket could also lead to warranty being voided. From the owner’s manual: “Volvo Cars accepts no liability for the consequences if unauthorised equipment is connected to the on-board diagnostic socket (OBDII). This socket should only be used by trained and qualified Volvo service technicians.”

There are many independent Volvo authorised garages.

Either find another dealer, or...

Go into writing to the service and general manager of the current dealership - you have a car with faults, that potentially is unsafe if it enters limp mode when overtaking on a A or B road, or in the outside lane of a motorway. Volvo pride themselves on safety, this is a safety issue - do they want you to have an accident to prove their safety ?

I cannot believe Volvo cannot see the codes another reader can, this i purely down to the fact they dont want to chase the root cause without someone agreeing to the costs incurred by the dealership.

If using another dealer is inconvenient to you then consider involving solicitor, even if its just an initial letter stating dissatisfaction at the main dealer's inability/unwillingness to fault find and rectify an unsafe vehicle.
