I got my V70 showing the ETS symptoms: ETS and check engine lights on with
engine going into a hiccup. I took the TB out and cleaned it with the the Volvo
cleaning solution. There was some carbon deposits around the throttle plate and
on the walls but not much. The cleaning helped for 2 hours and the hiccup is
back again.
It looks like I need to replace the unit. If I buy a new one I think I need to
reprogram it and I have no information on how to do it. Anybody has any info on
that?
Alternative is to sent my own for a repair. I found this shop on Ebay :

_throttle_system

that fixes it for $250. This should not require reprogramming. Any opinions on
using new or remanufactured?

VCNA has extended the warranty for the Magneti Marelli ETM to 10
years/200,000 miles. Contact your dealer.

Also, see:

for more information.

Good luck, Richard

I will be damned! I got the same info from other sources and confirmed it with
the local Denver dealer and have appointment for tomorrow to fix it.
Thanks Richard for a good link.
Pity that I did not get that info before I took on the weekend long project of
following the Volvo bulletin on cleaning the ETM. Taking the intake manifold
out, cleaning the ETM with the expensive ~$40 volvo cleaner, breaking things in
the process like flame-trap hose that was completely hardened by the temperature
in the cam cover area ($50), etc. etc.
Anyway it was a very interesting education.
We will see tomorrow how much of this $1200 warranty covered ETM repair is
really covered :-)

cheers
