For those counting...
This is the 2nd confirmation of this part number. This Air Temp Sensor is on the tube/hose that carries the compressed air from the outlet of the Turbocharger inter-cooler to the intake manifold.

What we have now is...
* 4 reports of sensor replacements on a 35d
* 2 of these have been confirmed to be the same part number
* we don't know about the other 2 yet

And I will be taking my 35d in tomorrow with a CEL lit and an OBD II code P007B which points to an Air Temp Sensor.

Maybe there is a 'common problem' or maybe just a coincidence. Time will tell.

I think we're going to find this is a common problem. Keep us posted...

Thanks,

Can confirm from part # that air temp sensor was what was replaced in mine.

Well, my wife took the 35d in this AM. After a chat with our SA about the OBD II codes etc., he said they would do the diagnostics while she waited consuming lattes & pastries

My wife called back pretty quickly and said they were in the process of replacing the ... wait for it.....
Air Temp Sensor 13-62-7-812-741. Imagine that.
Amazingly, our dealer actually had the part 'in house', BUT...
only because they had ordered one for another 35d owner who hadn't scheduled to come back in to have it replaced yet*.

My wife just called. The repairs are completed. So this CAN be a 2 hour 'while you wait' repair IF your dealer has the correct part in stock.

I'll post more details when she gets back with the 35d and the paper work.

* Our SA says he sourced the part for the other 35d in 2-3 days and notified them when it came in a couple of days ago. So because of how busy the shop is, he can get another one, before he can schedule their repair.

You're lucky!

I promised more details but there really aren't many. The paper work is very droll.
" CUSTOMER STATES CHECK ENG LIGHT ON
4C52 CHARGE AIR TEMP SENSOR PLAUSIBILITY STORED IN DME.
FAILURE OF CHARGE AIR TEMP. SENSOR.
INTERROGATED FAULT MEMORY. TESTED CHARGE AIR TEMP. SENSOR.
REPLACED CHARGE AIR TEMP SENSOR, CLEARD FAULT.
1 13-62-7-812-741 TEMPERATURE SENSOR WARRANTY $0"

The term "CHARGE AIR TEMP. SENSOR" is curious wording. I'm guessing it is short hand for "Turbo Charger Inter-cooler Air Temp Sensor" but I could be very wrong.

The failed part 13-62-7-812-741 costs roughly $25 retail. Because our dealer happened to have this part 'on hand', this repair only took roughly 2 hours So IMO EVERY dealer in the US should have at least one of these parts in stock.

Edit: I forgot to add that our SA said we could not have the old part if it was covered under warranty, unless we were willing to pay for it He implied (but did not explictly say) that the dealers return the warranty parts for reimbursement. Does that sound right ?
