C70 limp mode
My 2001 C70 2.4T is intermittently going into some sort of limp mode where it wont rev above 2000 rpm.
theres no warning lights Its intermittent - sometimes from starting , sometimes kicks in when driving. The trigger when driving seems to be asking a little bit too much work. eg pointing it up a hill in 3rd at 22. Problem can last 30 seconds or 15 minutes. It can happen 5 minutes into drive or an hour in. Garage found a throttle error code, hurrah! - have sent the throttle body to ecutesting.com for reconditioning but they cant find a fault Do I pay 200+ to recon it and hope its really the problem? Any other ideas? |

i think you might need to change the way you drive . trying to go up hill in 3rd from 22 is a lot of load with a heavy car. try changing down a gear and see if the problem still appears

1. Scan all modules with Vida if not already done
2. Get another throttle body from the junkyard, install it and try it out 3. Use some OBD-bluetooth thing + app on your phone and look at the long list of common PIDs while driving and while you trigger the problem. Make screenshots too. |

Get the codes scanned with Vida… there are a number of limp modes on these cars and not all of them put the EML on - for example if the wiring to the knock sensors or the sensors themselves is defective, the car drops to about 50% boost but no warning lights. It needs Volvo compatible gear to read them.
