Hi Guys..\r\nGot a 2001 c70 soft top,and during a shopping trip yesterday the car suddenly went into crawl mode(about 10mph)with no reponce from my accelerator when i put my foot down,but i managed to park up safely. My ets light and my engine light came on...after i paked up i put my cruise control off(as i always leave it on) and i got my performance back but lights still on..and it was idling really irractic...but it got me home...after a couple of hrs went bk to the car and both lights are now off,but engine is hunting ever so slightly...i,ve been redaing about the ets module going..which frightened me..but is there anything else it may be or something i could look at..i,m quite a compitent mechanic...removed plenty of engines in my time...but i have no clue on this,,,as its such a big engine and way to complicated... Thanks so much for any help.. Regards Tony

SOURCE: ECU engine management warning light

There is a problem, it needs to go to a factory service center, it can be any one of multiple reasons that turns this light on.

sounds like a misfire issue or a boost control valve

The best thing is to go to your local Volvo maintenance shop or Volvo experts to find out whats the problem..usually the coomon ones I think is the programs inside its ECU unit..you try this..ask the volvo experts to reset the ECU and lets see..if problem arise then it is no doubt you might need the sensor..hope this help..

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!
