Hi all - would be hugely grateful if someone here with more knowledge than me and/or VIDA could help me here please! Car is a 2004 S60, 2.0T, first of the facelifts which isnt usually relevant but seems very much so in the case of Volvo. Short version is that I've got what seems to be a noisy diff b...

So, to conclude the thread and hopefully provide some help to those with a similar issue in future... a new fuel pump seems to have solved it! STFT still bounces around a little but no more than my partner's Corolla of a similar age and mileage (always a great litmus test) plus it's not going to ext...

UPDATE: I'd been dealing with the issue for a couple of months by... not driving the car much and ignoring the problem. Finally got round to visiting yet another specialist earlier this week, reason being that this one had a rolling road. With the issue only manifesting itself under load, short of h...

Where are you on fuel pressure checking? The P2 platform does eat a fuel pressure sensor or PEM once in a while It's not been checked yet, though I've read pressure sensors can be the culprit. That said, mine is fine through the range unless under load, so surely it's more likely to be delivery tha...

I've fitted a new front O2 sensor as that was the next logical part to replace. It's definitely not fixed the issue, if anything the STFT values seem more extreme. After doing so I've also had a pending P2195 - O2 Sensor Signal Stuck Lean bank1 sensor1 and Torque states Closed loop, using 1 O2 senso...

It can go closed loop as soon as the OXS is hot enough to GIVE reliable exhaust readings. On my P80s that took about three minutes but the P2 is faster Three minutes (maybe a little less) sounds more like it. I just timed mine from the data recorded in Torque, it took 15 seconds from a 5c start bef...

Thought the parts to date had collectively resolved this to a usable point - i.e. no longer stalling... however I think a lot of "light" driving in traffic = no WOT = no chance for LTFT to spike... and stall. Foot flat to the floor on a sliproad last week, car choked and stalled while doin...

I’ve never monitored STFT under heavy load but it seems logical It should spike, doesn’t it.? That won’t cause the LTFT to bump unless you are flat out on the M1 all the time I'd say it's logical that it'll need to chuck more fuel in, but that the map would already know this therefore the fuel trim...

Some time off work over Christmas and a break from other projects mean I've had chance to look at this again. Being intermittent and having the easy short-term fix of resetting LTFT through Torque means I've ignored this a bit, but with some longer trips coming up I need to get on top of it... Inter...

This one's a 2.0T petrol.
