Gremlins in the electronics?

Glad I went ahead with the extended warranty and maintenance plan after all. I rolled in with 50,100 miles and was waiting to see my SA's face when he discovered I had bought the plan elsewhere. I was registered in the system and he could see I bought it from Pacific BMW. He questioned where they were located. I said a few hundred lower than you guys!

Ever seen what's involved in taking that pump out? From what I remember you drop the exhaust and all work is done from under the car. What confuses me is thecut out in the trunk of our car under the mat. They have bolts holding the plate down but the plate itself is glued?! Why?! it would make changing the components so much easier! If I ever have to replace my pump out of warranty I will see if I can cut an access hole to make life easier for future replacements. I'm on my second pump.

Hmmm, I wonder what this would have cost out of warranty?

I think I made a wise choice in getting the extended warranty. This DEF system must be eating their lunch.

Of course if I didn't have the warranty, and was having all these issues with the DEF, I'd be well motivated to have it deactivated. But then it would be the EGR or some other emission sensor or controller.

I got my car back Friday afternoon, so they had it for 5 days to do the 50k service and fix the DEF Heater system.

When I went to check out the cashier said I owed $53 for the warranty deductible. I balked and went back to my SA and reminded him that this problem had been looked at at a prior service and all they did was reset the SES and that it came back on, so it was not something new and should have been covered under the original warranty.

He had to check with "Management" and got the charge removed. So no cost to me.

So there is a $50 deductible on the extended warranty (need to read the fine print on these things).

We talked about the DEF Heater and how it was like **** on a bull here in South Florida. Of course tonight we have a freeze warning as temps are set to reach freezing from an artic cold blast. They indeed had to drop the exhaust and then the DEF Tank to remove the transfer pump assembly as the heater is part of the pump and not sold seperately. So I got a new Transfer Pump (ouch!).

Oil, Filter and DEF refill. Replaced Brake Fluid, Microfilter, and my wipers.

So I should be good to go for about another 13k miles or until another error code is thrown on one of the emission systems on this beast.
