something bad happened to my car

[Jersey Stephen]

so today i was fooling around on the road and so i flored my car and it would go 1mph faster every 5 seconds so then took my foot off the gas and flored it and it went back to normal do you know what happened

[Phrost]

Did you get a CEL? Sounds like you went into limp mode for a second or something... You could have had a misfire which put you into limp mode for a second, then everything was fine right after so things returned to normal...

If it only happened once and you have no CEL, I would just ignore it but keep an eye out for it to happen again. Don't worry though

[Jersey Stephen]

ya i didint get a cel and another thing is when i go fast it feels like my boost kicks on and off at a certain rpm ever ever since i got this Forge DV put in

sounds like the notorious fuel cut

[Jersey Anthony]

like i told you yesterday, it went into limp mode, and you have fuel cuts

[Phrost]

How can some people get fuel cut with basic mods like Jersey Stephen has, and I race on APR100 stage 2 with intake/test pipe and don't experience it?

I don't understand how some people get it and some do not

read this...and hope its not you

So after months of intermittent CEL’s, losses in power as well as trips to the dealership, it turns out that my B7 has been suffering from the ailment of bad Camshaft bearing wear. It’s being addressed as we speak… under warrantee.

I know that there have been numerous posts in this forum as well as others that identify this issue as one of the common problems to afflict the 2.0T FSI engine found in our generation of car. However, I also see a post every now and then describing the symptoms that I was experiencing but never a post about Camshaft bearing wear as the culprit.

I can’t speak to anyone else’s experience but perhaps there are more than a few of you that have similar issues to what I am going to describe. I just thought I would share…

a) A sudden loss or cut in power especially in higher gears and relatively low RPM’s (4th, 5th, 6th gear 2800-3800 Rpm attempting to accelerate to higher Rpm’s)
b) The ECU would then go into 5-15 seconds of limp mode where throttle modulation does not translate into any acceleration
c) The ECU would then come out of limp mode and everything is normal
d) a b and c do not always translate into a CEL but eventually it will (almost aways a code about fuel supply or fuel pressure)
e) CEL will go away in a day or two

The technician at the dealership will likely troubleshoot the issue by addressing the symptom of the problem rather then the root-cause. This, for me, translated into replacing fuel pressure sensors and such. Eventually I realized that the problem still persists and that altering my driving style did nothing to prevent the symptoms from reoccurring.

I’m hoping this time the dealership has the cure…

Take it to the dealer. If they run a diagnostic and tell you that it is a bad fuel pressure sensor, insist that they check for cam lobe wear. Dont take no for an answer.

dose any body have the kmd fuel pump

Sounds like cam lobe wear strikes again.


check out #4 in the common issues sticky

[Jersey Stephen]

so dose this mean i need new cams if i do im going to buy the kmd ones and a fuel pump

[Jersey Stephen]

but this only happened when i got the Forge DV put in

but this only happened when i got the Forge DV put in

The basis of the cause and effect relationship are weak. If you want to know for sure swap out your DV for the stock one.

[Jersey Stephen]

im going to put the stock one back on and if my car is back to normal and send the forge dv back for a new one

[Jersey Stephen]

it happened again limp mode this time it was for a min

[Ski DraGoN]

take it to the dealership

[Jersey Stephen]

there going to avoid my warranty
