Down on power........
Hi, my first posting as a new member so bear with me please.
S60 D5 Auto, circa 2002, 85000 miles. Problem is from cold only, if driven 'under load' i.e. approx 1/2 to 2/3rds throttle, up an incline, a message "engine service required" shows, the car apears to go into limp-home mode and fault code ecm6805 is recorded. (This does not happen if driven on light throttle through the warm up period). Switching off the engine extinguishes the message & restores performance. Once the engine is warmed through, and for the rest of the day there will be no problem. On the strength of said fault code, i have tried a new turbo controll valve with no joy. Any ideas please? |

As discussed on T5D5, new intercooler has sorted mine.

Yeah, they are a bit prone to intercooler leaks but i cant help thinking i would have the problem ALL the time (not just through warm-up) if this were the case. Please keep an ear to the ground & let me know if anything strikes a chord. appreciate your interest.

Chord stuck!
Mine would occasionally bring up the 'engine service required' within 200 yards of leaving my house, admittedly as I accelerated up a dual carriageway. Engine would still have been cold, torque is addictive my bad! Once I had read the message it would then not reappear until the next day. I guess it could have been throttle dependant, I don't always attack that bit of road with the same vigour. If I drove the car during the day, (engine not cold), then I would not get the message. Sounds very much like the trouble you are having... At the start of the trouble I didn't feel any loss of performance. Strangely once the problem was identified I started to notice things weren't quite right. I accelerated up a motorway slip road, engine cold'ish, felt boost suddenly back off and the usual error message came up. Since the new intercooler its back to its old self again, I'm happy I'll PM you as well. Hope that helps! Andy AKA Redbrick |
