ETM Replaced but no software ?

Hi Everyone,

I have just bought a 2000 V70 2.4 non turbo, the poor old boy who owned it before me spent a mint trying to fix the ETM, Got the car on friday and it drives well untill it's up to temprature - then the ETS light comes on and it's in limp mode,
The previous owner has replaced :-
ETM shiny new volvo one with a bright yellow sticker !
Throttle pedal
MAF Sensor (again from volvo)
O2 sensor
BUT aparantly the indipendant garage that did the work could not load the ETM software.... (said it would'nt accept it ???)

No codes listed when in fault condition - but i did get a p16** (comms fault) but cant get it to re-appear
I'm hoping that it just needs the new etm paired - in that case i've got a real bargin!!
When it's in fault condition it idle's really bad (like a missfire) - idle is around 1k, dosn't stall but wont rev past 3k & when you press the throttle it revs slow (smooth's out at 2k) then drops to 1500 & bounces back up to 2k and back to rough idle....

It's booked in with my local dealer on thursday for the software.... But....

1. How come it drives fine when cold?
2. ETS light comes on - but no codes
3. what are the symptoms of not loading the software on a new ETM ?

Thanks in advance

Steve

HA HAAAAA!!! you are so smart. I've been saying this for awhile now . Just check it out on the link below. The only reason I'm posting this is to help other Volvo owners find the right solutions and not spend too much money on a simple thing.

Sorry but I hope it helps many other volvo owners.

Please make sure your battery is maintained and replaced at regular intervals. Engineers have to work withing design limits and when the car's DC bus sags, everything electronic can/and will be affected. we can't make fans, ETM, sensor work properly with 8vdc. it just doesn't work.

Ouch, check out what Bobec at http://www.volvoforums.com said about MVS in the link given by Fast850 at http://volvoforums.com/forum/showthread ... post233390

With all due respect.... You're welcome.
I mean where did you get the supply voltage idea?

Now If you want to help all Volvo owners escape this F&^%ing witch hunt that is going on on Matthew's site you can make it known that bobec from volvoforums steered you in the right direction.

Don's ETM room is a joke made by people who know S*&t.

The magnetti Marrelli ETM is an engineering master piece and it's getting slammed by a bunch of F*&^ing idiots.

Some of us do appreciate a genuine desire to help, and I surely do hope that no MVS member would sink to this level to arbitrarily slam another website and its members. Unprofessional and over the top response by Bobec, a shame to the Volvo community!
