Hey guys- SO I just got my new turbos put on under warranty and got my mods back on. Anyways now the fuel pump is gone. I keep getting long cranks and when I put it on a map other then stock the car gets limp modes and SES lights. I erase the codes and put it back in stock map and it will do long cranks but no lights so my question is should I leave the codes and take off the tune or what? I want to get the hpfp replaced but don't want them to say nothing is wrong but long cranks? What do you guys do. Obviously I would take the tune off but don't know to leave the codes or not. I have always erased them before taking the car in so I am a bit scared in case they can tell I had a tune.

I would leave the codes there if they are all relating to the hpfp. You have a much better chance of them replacing the pump with codes than without.

Mine started to have random long cranks but no codes and all they did was update my software.

[jcarlucci1]

They wont replace it without the codes. I would erase all the codes, take the tune out, drive till the hpfp codes come back, then take it in. Thats what I did, otherwise you risk codes that may be tune related..

[Jeff@TopGearSolutions]

Leave codes if they are HPFP related. IF you have tuner related codes, Clear all Code, take tune out, and wait for HPFP codes again.

Why don't you just take the chip out since you are having so many problems. Its also called fraud.

[kennejp]

Whats fraud? The turbo/wastegate rattle and the hpfp are both known problems that have nothing to do with the tune-if you dont know what your talking about please dont comment.

[huyner328]

I would recommend taking the tune and mods off clear codes, driving around untill you get the SES or something again then it's time to check her in.

[kennejp]

Ya just talked to Terry and that's what he recommended also.

its highly doubtful that ANY fuel system component will get replaced if you go and erase relavant codes

that is one primary requirement in the repair/replacement process...

I pick my car back up tomorrow after the same issue. I had the same codes and all they would do is a upgraded software until that proves not to work. I'll drive it around for a week or so before I put my mods back on just to make sure. Good luck!

Same thing is happening to me. Got my car back last Thursday after long cranks and it just started getting long cranks again today!

O man watch out here comes mr. horsepower cock block.

[kennejp]

SO you guys still think I should clear the codes and try and get them to come without the tune? I mean there are long cranks but it hasnt limped or ses since going back to stock map
