2000 XC70 - A little help with diagnostics, please?

[dislusive]

If he told you 117 volts he's feeding you a line of BS. There's no way there could be that much voltage - your whole electric system would be fried and your car probably would have started on fire.

I am quoting this verbatim from my receipt. "Scanned for codes and found ECM-8010 for battery voltage. Found battery cables corroded and cable to the starter is hitting 177 degrees."

Picked the car up from the dealer about an hour ago. The car drove fine for the first 25miles. The problem is happening again! ugh!

Highly ticked off... There was less than 2 gallons of gas in the car when I picked it up, there was over a half-tank of gas when it was towed there! grrrr!

The car is blowing out blue smoke every time I hit the gas! I checked the dipstick, the oil was full (at the max line on the dipstick) for over a week before towing it in, right now it is sitting at the min line of the dipstick. It wasn't blowing smoke prior, and I didn't have an oil consumption issue. Is this normal after an ETM cleaning, perhaps?

I guess the cleaning of the ETM was a temp fix? Damn it. If I didn't live so far from the dealer, over an hour drive away, it would be right back there right now. I will have it towed there *again* tomorrow.

Will never buy another Volvo...

Sounds like someone took your car joyriding. What is the odometer mileage difference between when you took it in and when you picked it up?

Cleaning the ETM should have nothing to do with the oil level or the fact that it's smoking now.

I agree, and it definitely didn't take much to replicate the issue. BUT they could have at least of put gas back into it!

I didn't think the ETM cleaning to related to it blowing smoke now. This is a bit ridiculous. Sounds like they need to replace the ETM, and I'm not at all sure what would be causing the oil consumption.

Here's the rest of the verbage for the fix.

"Client status idle surges. Found idle to be surging, check ventilation and it is good at -2.5KPA. Performed sweep test on the Electonic throttle Module and it passed the sweep test. Removed the ETM and found to be badly carboned inside. Necessary to clean the ETM and reinstall with a new gasket."

It seems like the dealer is causing more problems than they are solving.

What can I check to see where the issue could be, or should I fight to have them replace the ETM?

[vegasjetskier]

If the idle is still surging, go for a new ETM. If the dealer doesn't want to do it, call the 800 number from the Trew, et al webpage to light a fire under them. I'd call right from the dealership. But that's just me.

Sounds good to me. Will have it towed to the dealer tomorrow morning and will call Volvo directly and tell them the situation, if the dealer doesn't agree to replace the ETM.

Thanks for the advice, Vegas.

It's not just that the idle is surging, it's that when the RPMs dip so hard, the transaxle arrow flashes on the dash, and the idle surges it literally causes the car to move forward, unexpectedly. We're talking feet. This will cause an accident one of these times...

I'm about to cry. Leave for vacation this weekend, over a thousand miles round-trip, and relying on this vehicle to get my family there. Only have until Friday to get this fixed. Wasted the money I was going to use on a rental car to repair this car.

I figured it out!

The hose connecting the front of the car to the air filter housing had come off. Car runs fine now. Have to check over the dealers work for now on /sigh.

So you had a "hot air intake?" That shouldn't make your car burn oil.

Foot-in-mouth anyhow.

The idle is better on start-up. After running about 10 seconds the idle will surge to about 1500RPM for about 10 seconds then go back to 900RPM. (only when cold)

Breaking from 45+MPH still causes the the RPMs to dip enough to light the transaxle dash arrow, the car to want to stall, and the idle to then surge. Seems like this only happens "on demand" if the turbo is kicked in. It doesn't seem the car is jerking forward now though.

Still seems like an ETM issue, and I need to figure out the oil consumption issue. The smoke is more white/grey than blue, so I don't think it's oil. Perhaps I have a leak, but I don't see any oil spots in the driveway where the car is always parked.

Hoping the ETM cleaning holds me over to get through vacation traveling, and then I can buy the XeModex part.
