SOURCE: 2001 volvo s60 t5 - performance reduced warning message, limp mode activated

I had exactly the same problem on my UK 2001 S60.
It was caused by the throttle control housing gaskets not being serviced properly and consequently the entire housing had to be replaced - not a cheap job -and a valuable lesson learned - use a reputable volvo specialist to service your volvo - I didn't and I learnt the hard why! only a volvo specilaist would have known about this I went to several other main street garages & none of them could even diagnose the problem let alone fix it. Although they did do numerous other things first before they gave up - ie replaced titanium spark plugs.
Before it stoppped running altogther and went into "limp home mode" there were tell-tale engine/throttle surges when the car was idle, but in gear.
It is now running "like new" & I will never get another garage to service it, as this could have been avoided - however they can also wear out after about 10years - so my bad services just made it happen sooner!
I hope this helps!

SOURCE: volvo xc70 in limp mode 7 fault codes recorded d5

Possible problem with the alternator not putting out enough voltage. I had the same problem with my 2002 XC70, putting in a new alternator fixed it. I used a local mechanic who I found on the car talk web-site. Low Cost Volvo parts can be purchased at FCP Groton.

Does limp mode correct itself after known repaire needs are met or is a chip needed for reversal after repair, or just whats the process to recover from limp mode?

the limp mode is triggered when certain parameters that protect the engine/transmission from serious damage are exceeded
having run the fault codes to determine what caused the failure and then having repaired those faults , it is a requirement that a scan tool is used to reset the ECM back to pre limp mode readings
There is nothing in the cpu program that reads when repairs have been effected so it is up to you to reset the system

How can you tell if a new gearbox is needed other than a Ecu which has been replaced

have the fault codes read first
if the car is moving in limp mode with no obvious noises or problems , replacement of the box is a total last resort
light on the dash and limp mode can be transmission or engine or both but the fault codes will show the problem area
The ECU -- engine control unit or ECM --engine control module gets messages from the transmission control module ---TCM--and that TCM controls solenoids and servos , vss and other items that if faulty will put the car in limp mode
read the fault codes

2004 XC70 has been off the road over two years. Put a new battery in it, ran fine for a couple of days, then threw code p2111 throttle sensor stuck and rough idle also known is limp mode. Erase code and it...

You might find that the throttle sensor which is electronic and part of the accelerator pedal has become unresponsive due to lack of use.i had this problem with a ford maverick which had been sat idle for a few months. And this caused the engine management light to come on and throw into limp mode.my cure was to press the pedal up and down quite hard with the engine switched off.also did this to the clutch pedal.cured the problem but every so often for the first year of regular use it would repeat.so I just pumped the pedal fully up and down whilst engine was off.no more limp modes.

I have xc90 d5 there is warning message came of engine system service required with power loss how to solve

Hi,

This is probably due to a problem with the swirl flap actuator arm - if you remove the top of the engine cover (the plastic bit) and look at the top, left front of the engine, do you see a plastic arm (approx 70 - 100 mm long) disconnected?

Regards,


RK

Soot filter and engine service light on, can I regenerate or will that cause harm to engine

These can be regenerated without harm to the engine. Volvo has a procedure for doing this. I have not seen it published for the general public. You should be able to politely ask a Volvo servicemen for the recommended procedures and they will generally help you out.
