I know im late to key in but my dealer told me when I bought the truck that as long as it was after the cats it wouldn't bother the warranty.

Ok, I have to step in here. Sorry I did not see this thread sooner.

I had my '11 in for this exact issue. My service manager and I thought it was the torque converter. However, after not one, or two, but 3 converters, the noise was still there (there were other things that led them to replace it 3x too).

The day I went to get my truck, my service manager and I spent 4 hours driving 6 other Ram's, 3 new and 3 used and ALL of them...EVERY one, made the noise. Sounds kind of like a playing card stuck in a bicycle wheel right? just not as loud? and only on coasting or under VERY light throttle application. Turn off MDS with tow/haul or by selecting a gear on the trans manually and it goes away.

Come to find out, it is the injectors of the cylinders that are not receiving fuel in MDS mode. It took my dealer techs 3 days of diagnostics with computers and equipment to narrow it down. They even placed my ram on a dyno at a shop down the street so they could drive it with the computers hooked up to get readouts. The results are conclusive, there is absolutely nothing wrong with your truck, other than its making the noise...

How are they not receiving fuel? I thought they just didn't open and spray fuel, as the fuel rail is fully pressurized all the time. Doesn't the ECU just not power the fuel injectors when in MDS mode? Am I missing something here?

You would have to ignore the most obvious and damaging symptom: being that of burning a quart of oil burning to dismiss such a serious engine problem that he has. For an injector to make noise, it would need some form of energy to make that noise., either miss-happen electrical signals or faulty pressure regulation. Either way, a proper deactivated fuel injector should be silent.

I don't know about Canada, but in the states we have a thing called a "lemon law". Some states are different on how the law reads, but I had dodge/Chrysler buy my 1st 2012 Cummings back from me. They don't want the bad press. Look up your lemon laws and put pressure on the dealership.

Unfortunately here in Canada we only have the BS law, so no go for us.

They take the valve covers off and there are 2 tabs on the retainers. They either bend them inward or outward, doesn't matter and that cures the tick. They are hitting with the pushrod rhythm.
Clifford. The above was posted in another thread. Maybe that helps.....
