Not really helping with my v-band leak though is it??

**Wobbly Dave** · Monday 7th July 2014, 01:01

I went to HLM to use the smoke machine, just over a week ago, as I was no longer certain if it was the v-band still leaking.

Turned out it wasnt the V-band after all. No the main culprit was one of the 6 bolts holding the semi-circular clamps on the turbine hosing. It'd worked its way out. Finally got the replacement bolt in this evening (been a bit pre-occupied). You can see the offending article just to the right of the CHRA water connector.

Oh & she passed her MOT too. thanks again to Hamish for the loan of the smoke machine, without which I would still be chasing my own tail.

Very happy that it has stopped blowing. Just a shame I wont get to use the car in anger this year (at least I doubt it).

Great news you found it dave minds well let me use that turbo now saves you having to put it back in

He wants it in the 13s, not the 15s.

If you bring it back in 1 piece. I'd sooner have it put in a time this year than not.

Yeah, I'll run it, I know what it's like to get into the 13s.

**JUDGENINJA** · Monday 7th July 2014, 13:36

Problem is your car should be in the 13s standard!!!

As you may know I've had a few issues with my ETM - well the codes & the light & the rough idle all pointed towards the unit being at fault. Anyway I used VolvoDiagnostic to prove the contactless upgrade/repair. I put the unit back on this evening. Still not 100% happy, so I think I will replace the throttle position sensor, at the top of the throttle pedal. Oddly on the test drive I was able to get the full range of pedal/throttle movement, but when I tried to heel'n'toe the downshift, I got no throttle response at all. Still feels a little hesitant/unwilling - not all the time mind.

Is there a bedding in period for the new ETM? Should I leave the battery off overnight?

**stribo** · Monday 4th August 2014, 01:12

I'd imagine (though I could be talking ££££££££) that if the ECU detects the brake switch has been activated, it would cut the throttle.

**Wobbly Dave** · Monday 4th August 2014, 01:23

it always used to heel n toe without any issue, when it was running right.

**M-R-P** · Monday 4th August 2014, 08:00

How long was the test drive Dave?

Like a TCV, it "might" take a while to adjust to the way the engine reacts to the throttle input. Might be worth pulling the battery for a couple of hours, then going for a gentle drive, then a slightly spirited drive etc.

Did you look that the tps voltages when pressing it? Should be linear afaik.

I'd be suspect of the ETM if it's the only thing changed.

Can you map this thing?? is is the technology below what you work with??

ME7 is ME7

But, I'm not interested in tuning any other stage 3 cars until I've wrung the neck of my caR first.

One thing I have just thought of, back OT. The ETM position is one of the very few variables stored in the Volvo ME7 EEPROM, which will survive battery off etc as it is non-volatile memory. A code read and clear of the ECU/ECM should clear those stored values, idk tbh, but it might help.

**Wobbly Dave** · Tuesday 5th August 2014, 00:02

The purpose of the ETM repair was 2 fold. To keep the need for having to code a new ETM to the car and to future proof it against the original design flaw in the original sensor.

ETS light came on again this evening. I was going to run Betsy up to the hospital (as I was going up there to see my new daughters), but decided against it.
I am going to HLM tomorrow. I will change the pedal as both parts were over 120 K old. To my mind keeping the maintenance in step makes sense. Then if there are still issues then we can address them.

**deathrider311271** · Tuesday 5th August 2014, 20:38

the ECU needs to learn the new values of the ETM, do as dream3r said and get rid of all codes with vida dice, then switch the ignition to [position 2 (dash lights on) but do not start the car, leave it in this position for a MINIMUM OF 10 MINUTES. Turn to off position for a MINIMUM OF 2 MINUTES, then take for a drive gently at first slowly introducing more throttle.
It will take a minimum of 50 miles for the ECU to completly learn the new values.

Your accelerator is the throttle position sensor, you cant just change the top part, Volvo will sell you a P2 accelerator as you cant get the P1 version anymore, mine was about £90 from FRF swansea

Some of the snag list was resolved. Service light was done. SRS light is the SIPS bag in the drivers seat. I have a spare seat - its not the GT seat I prefer but funds are limited. So although not resolved - at least I know where it is.

ETS turns out to be a P1172 code - long term fuel triim. Few issues though, which oddly seem to resolve themselves. There was also an intermittent ETS fault registered. The ETS light has been on but for other reasons. Oddly the previously inoperative cruise control has returned & the heel'n'toe issue has now returned to normal.
I may yet pull the battery overnight, reset the fuel trim & see how we go. Need to check the system for airleaks following the ETM restoration. Temperamental or what??

Air con has been regassed - so thats nice and cool - even though the nice weather has done a runner.

**Wobbly Dave** · Tuesday 12th August 2014, 23:20

Lit up like a fkin Christmas tree FFS. Betsy is sorely trying my patience.

I did reset the fuel trim by leaving the battery off and tried to retrim the throttle response. Drive Train & ETM warning lights were coming on and off with a mixture of Turbo Overboost Condition (P0234) & then to cap it all the ABS light put in an appearance which might explain the intermittant/ mostly absent cruise control. DTC said P1550 (speed signal).

So I changed out the ABS ECU for a spare I had - after finally discovering the safe place I'd put it - even though the one coming off was one of my own repairs from 2008.
I disco'd the battery when I unplugged it all, just to be on the safe side. Put it all back together & started her up.

ABS light has now been joined by the brake warning light (the red one with the circled exclamation mark in it).

Idle is irratic but as far as I can tell the long term fuel trim code has not returned, but most annoyingly the ODBII port/ECU is no longer talking to the code reader bluetooth device - so I can't bleedin' tell what the brake warning light is doing on.

I am also paranoid that the rate of coolant depletion is something slightly more sinister than an air trap. I have a headgasket sniffer test kit but I am somewhat reluctant to use it, as I am almost certainly in denial. Not a happy camper
