does a new ETM need to be calibrated at a volvo dealership?
What is your question?
my 2006 v70 turbo sputters at idle and gas mileage is poor. my research indicate that the ETM needs to cleaned or replaced. engine has 200,000. i can get bosch OEM on Ebay for $125, including casket. i called Volvo to check on part number and was "warned" that if i put a new ETM on, then it will not run right unless a Volvo dealer does a computer upgrade to calibrate the new ETM. this sounds like BS to me and just another way for Volvo dealer to suck my $$$.
i already replaced the mass air flow sensor. no change. check engine lite goes on for awhile, then goes off.
would appreciate your advice.
What makes this problem better or worse?
it comes and goes in all weather conditions.
How long has your 2006 Volvo V70 had this problem?
RepairPal Certified shops can diagnose and repair your 2006 Volvo V70. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
There are many potential causes for your concern. So, first of all, I recommend a proper diagnosis of the vehicle before assuming the electronic throttle module (ETM) is bad.
Should you decide to move forward with the ETM replacement, I do recall doing a "throttle body relearn" on some Volvo models. But I don't remember whether the procedure was required on your 2006 V70. The factory repair information mentions nothing of it.
In other words, I'm not sure whether your particular car requires adaptation. If you want to get a second opinion beyond the dealer, I recommend calling some independent shops that specialize in European vehicles. They may be able to tell you if adaption is required -- and they may be able to do the job for you (with an OEM-level scan tool) if it is.
