Changed the fuel filter, got a CEL

Changed the fuel filter, got a CEL (Solved)

Hi guys,

I changed the fuel filter on my Golf R and I got a CEL

I scanned it and this is what I got..

VCDS Version: Release 14.10.0

I didn't have this CEL before changing the fuel filter. I changed it with this one

http://www.ecstuning.com/Volkswagen-Golf_R--2.0T/Engine/Fuel/ES2550239/

I did some research and according to ross-tech wiki these are the possible symptoms, causes and solutions.

P310B/012555 - Low Pressure Fuel regulation: Fuel Pressure Outside Specification

Possible Symptoms
MIL On
Reduced power (which I am experiencing)

Possible Causes
Faulty Fuel Pressure Sensor (G410)
Wiring Harness for Fuel Pressure Sensor (G410)
Low Fuel Pressure
Weak Lift Pump
Restriction in Fuel Filter or Fuel Lines
Mechanical issue with High Pressure Fuel Pump

Possible Solutions
Replace Fuel Pressure Sensor (G410)
Repair Damaged Wiring
Remove and inspect High Pressure Fuel Pump

Now, what do you guys suggest I do? I already erased the code twice and it keeps appearing..
I think it has something to do with the new fuel filter as with the old one everything was fine. Unfortunately I cannot change it back as I tossed the other one away

I appreciate your input!

you didn't have the code before the filter change, correct. Get another fuel filter, try it first, then the pressure sensor. I'd buy them both at the dealer and return the pressure sender if the filter fixes the problem.

After reading ECS's description of the Mann fuel filter (inter pressure regulator) it sounds like it's the fuel filter.

I agree, it is possible the (new) filter is defective, or the connections to it are not solid.

I would do what bebersol says -- at $22 i would buy another filter, install it, and see if CEL goes away

Wow.. So I got the wrong fuel filter, that's really disappointing. Just like you I bought the one that ECS claims is the correct one for my car..

I guess I'll have to buy another one, the "correct" one..

Do you guys know where to find the new "correct" filter?? I checked in ECS and the 4 options the offer have the same manufacturer number. (I should have the correct one then, but obviously not) They all say "With internal pressure regulator"
So I'm really not trusting them right now on having the correct one for our cars..

Thanks for your help guys,

I'll keep you posted if the CEL disappears after I find and change the filter..

Check the VW part number on the original filter, and fork over the cash for the actual VW one that matches. I bought the OEM one listed by ECS and have had no issues.

And there's also a chance that the filter you received is simply defective.

Yeah thanks, thing is I live outside the US so making ECS give me a refund to change the filter seems unlikely for me..

I guess I'll have to buy the OEM. I'd like to grab the original OEM filter sold by ECS, but it has the same manufacturing number as the others they sell, I know it is the OEM but I don't want to have the same issue again, is there a way to check if the filter is the 6 bar we need?

Talked to the ECS customer service and here is the conversation if anyone cares..

Apparently I have the right filter and they recommend checking my fuel pump control unit before listing the filter as defective. I tried to explain them that before changing the filter I had no issues but they were sure the one they sell is the correct one.

At the end I got desperate and told them I didn't care if I didn't get the money back, I just wanted to be sure of getting the correct fuel filter for my car. They weren't that helpful..







So now I'll be ordering the OEM fuel filter from Amazon and I'll hope this will solve the problem!

I'll keep you posted

Fuck ECS. I avoid them at all costs.

Wow what a dick - this is the second bad ECS customer service ive seen in the past few days - looks like they are going downhill

He agreed with me and said they'd pull the filter from the site. To be clear, it was "Mann Filter ES#2713062"
I find quoting forum's is never respected right/wrong. Sucks because forums have a lot of knowledge in them but a lot of junk too.
I've had good experiences with ECS but this certainly got under my skin. I'll just be more cautious in the future. They are, largely, a good resource.

Hi Guys,

So I solved the issue.
ECS Filter was the wrong one, ordered the correct one from amazon. Installed it and everything works perfect again, no CEL, fuel consumption went back to normal and car feels great again.

I haven't checked but hopefully ECS removed that item of their product list.

Cheers!

Good News
