The exact same set of codes have just come up on my car, the same car and year. Did you solve it? I am thinking cleaning the throttle body first, any help appreciated....

    Just had two of the codes come up on my S80 2.4 5cyl
    From what i can make out P1610 is the dreaded "ETM" (Throttle unit internal fault, signal to high.)
    P2172 is Flasher unit
    Cleaning throttle bodie tommorrow.

    Try these sites for info,

    Hope this helps.

You will need a repair shop to get those codes again,
& they will have to diagnose the issues

Regardlees of many peoples feelings, no vehicle can
accelerate on it's own

Any somewhat related syptom can be found & explained
Not a safety issue

We have no access to manufacture specific codes, some
of which you gave us

This is probably a faulty Throttle Position Sensor - I had exactly the same problem.
Vovlo specialist hooked my ODBII to a code reader.

Best to get the throttle body cleaned at the same time they replace the TPS

All in £125 plus the dreaded VAT.

Hope this helps
