What is the right part # for LPFP replacement?

[jayM]

Hi All,

I've been getting the code 12555. I want to price out the replacement parts for when I plan to swap out the LPFP. I have searched and come across two different part #s.


8E0919051CQ

or

8E0919051AK

There is about a $50 difference between the two versions. Is the CQ the updated part number? Any help would be awesome.

(this is for a 2006 A4 2.0t Quattro)

I run the TTRS 8J0919051D pump (spend $550 for the damn thing), but it has been superceded by 8J0919051E which you can get for around $350 from ECS. I think it is also the same pump now used in the TFSI engines.

Came back from the dealer and its definitely not the sensor. They ran the logs and I will have to replace the lpfp. Any help with the part number?

I checked europaparts; the only in tank pump listed on europaparts I can find for a B7 Quattro is the CQ. Then I checked GAP, and the part listed there is the AK (I did search for the CQ part - it popped up for the 4.2L). If it was me, I'd go with GAP, and during checkout put in your VIN and they'll make sure it's the right one.

Or maybe call your Audi dealer's parts department to get the definitive answer, lol.
