I had my car in for the 52,500 service. I complained about my engine surging at idle especially under the a/c load. They told me that the 'required maintenance' was to clean the imfamous ETM because of carbon build up and charge me 2 hours labor @ $94 per hour. I told them "no".
My complaint is this, why wasn't this done when the car was under warranty. I had the car in twice before; first time new upgrade to software. Second time was MAF was replaced. Why didn't they just clean the ETM when under warranty?
It's at times like these that I wish a recall would be announced.

If Bruce or you are in California or Maine, it is possible that you can get Volvo to cover the ETM cleaning and replacing, but other states have not got the laws in place for this...at least not YET.

The reason that the ETM wasn't cleaned under warranty is because it's in the 60K mile service. It sucks but true. I'd still complain to the service manager and ask him about their "Goodwill" clause....Yes, they do have such a thing and can do it if they really want to.

It's not just about 70 series cars...the 80's have terrible (same) ETM's too.

If you compalin to the service manager they will cover the parts and you get the labor around 90 to replace the ETM. Believe me it will get undrivable around 80k. Look out for the ABS going around 100k and tha tis over 1100 to replace. By the way, do you work for UPS? The User name looks kike a rackf id.
