Hello, I bought a used 2000 v70 a year ago, and four days ago I began
to have acceleration problems. The dealer at first told me it was the
knock sensor and replaced it, but now they claim the entire ECM needs
to be replaced. I asked them if they could find me a used ECM, as hey
have found other used parts in the past, and at first they agreed, but
just called me back to say that a used ECM would not work because each
ECM is linked to the vehicle's VIN number, and if it doesn't match the
actual VIN number of the car, it will simply not function. This
sounds a little suspicious to me, though not impossible. Do any of
you know if I'm being fed a line?

Thanks a lot!

The ECM is coded to the chip in the key, it's got nothing to do with the
VIN. Volvo will probably have a database relating the VIN to what ECU
is in the car.

No you're not being feed a line but it sounds like the electronic throttle
module is what is causing your problem this is not a cheap part it does not
pay to find one in a junk yard due to the labor to install the ETM

"*-344-*Never Forgotten"
Is for the New York City Firemen who lost their lives on September 11,2001.
The official count is 343, but there was also a volunteer who lost his life
aiding in the initial rescue efforts. And I will never forget them as long
as I live,
nor should any American.

Just been back from my Volvo dealer in Limerick, Ireland. My V70 has
been over-revving (rec-counter is at "1" when sitting in neutral) for
the last week and they reckon I need a new ECM and "softwear". They
want to charge me 945 EURO + 45 EURO for "softwear"; of course this
excludes VAT and Labour. How could an ECM fail in this way ?
