For any one who has had the misfortune to talk to me on the phone, then odds are I told you "anything with an electrical connect on it, GET....IT....FROM....THE....DEALER!".
2015 Audi S3. Owner of car was driving home, car dies. 10 minutes later car is running again and makes it home. Scan for fault codes (unclear what codes were there) and decided to replace the Fuel pump control module (J538). Still having issues and car is dropped of at the repair shop.
Current codes at time of phone call:
14994 - Fuel Pump Control Module P025C 00 [00100000] - Short to Ground
14995 - Fuel Pump Control Module P025A 00 [00100000] - Electrical Fault
I suggest to check wiring for J538, that checks out all good. I suggest to get new J528 and this is when I was told owner of car put in a new factory unit. Hmmm... ok, so I says PL24 that would be part number 5Q0 906 093 C, can you verify that? I'm being told there is no part number on it, looks like part of a sticker has been cut off.
Send me a photo of that and here is what we find:
Click on the images to see the full size. So that is in fact some sort of "OE" part, but 85% of the factory decal has been removed, you can see cut marks in the plastic. This is not a good sign folks. Here is what it should of looked like:
So removed part numbers can happen for a few different reasons, none of them good reasons. It could of been from a failed production run. It could be recalled parts. If you get get an "OE" part, and the VW/Audi part number has been removed, I would suggest you not waste your time with it.
The tech gets a new unit from the dealer... and still has issues... ugh... come to find out the owner replaced the lift pump from sketchycrap.com after swapping the J538 didn't fix the issue. Thankfully the owner still had the original lift pump so the shop put it back in and with that, the car was fixed and running great again.
So... it would seem that the original problem was a bad J538. Had the owner of the car got the J538 from the dealer at the start of all this, the car would of been fixed early on. Stepping over dollars to save dimes is not the way to go.... that cheaper J538 ended up costing the owner a lot more. So again I say... anything with an electrical connect on it, GET....IT....FROM....THE....DEALER! All of us at Ross-Tech have lost count the number of times that a good diagnosis was ruined by a substandard part.
