- I'm tracking down a misfire condition and smelled a bunch of fuel coming from the oil cap when opened.
I replaced the HPFP because it is a typical culperit and easy to get to.
I will need to change the oil and filter next to see if gas smell stays present. If its still there, I may need to look at injectors being stuck open.
I did not show the inspection of the cam follower in the video. Be sure to pull it out and check for scoring and bearing noise. Replace if needed.
Props to you dude for holding the camera on ALL bolts removed along with sizes thanks!
Wondering why you didn’t address the Cam Follower?
This is a really well formatted video, easy to follow along. I would say, it would be good to include the fuse box location next time and also specify that it is necessary to use a long triple square instead of a regular socket. I already had a regular so didn't think twice. Luckily i was able to buy one locally.
Dude, at least look at the cam follower.
When i started my A5 2.0tfsi it suddebly started pouring fuel out of the side where the black hose connects. Do i need to replace the whole pump then?
If it's just leaking from a cracked fuel line, you can replace the fuel hose by itself.
Where is located that fuel line that leaks to engine, I think I have that issue every time I change oil , I smell gas on oil
I didint saw cam follower? 😢
Was this car running bad
I replaced the pump just as in the video, placed back the fuse and pushed in the FOB. The car turned over and thought the lord answered my prayers. It idled for about 20 seconds, then engine started convulsing and engine shut off. I wanted to try the fuel regulator sensor first but could not find one anywhere in the local autozones. I feel defeated and depressed. Why did it have to start and run for a bit? That makes it that much worse.
My first thought would be to make sure the fuse was put back in the right spot. It is weird that it would run for a few seconds then shut down. Double check that the fuse isnt't blown as well. I think its a 25 amp fuse. Do you hear the fuel pump turn on when you open the driver door?
@@elvrolet air in the lines, just run it more
I got a bad gas smell in oil and car runs bad at low rpm and hard starts its a 2014 audi . Wonder if this is the issue
This car had a misfire. I did find that it also had a fuel injector that was stuck open later down the road.
@@elvrolet dam I checked to see if the plugs where wet and noting on all 4
@@elvrolet good info, I'll remember to check for this.
The miss is from the amount of fuel in the oil... Mine does the same crap, I wonder if you can buy a plunger seal instead of replacing the pump?
Można 😅
@@dawidsz.6029 I read also an injector can hang open...
Tak ale blad w tym przypadku to wypadanie na 1 cylindrze oraz blad wypadania zaplonu ja wielu cylindrach @@itskarl79
I get a rattle snake sound coming from the engine bay. A mechanic said that it's the HPFP that needs to be replaced. Fuel pressure was at 38.90 bar and he said it should be way higher. Also pressing the acceleration pedal, first there is a lag, engine increases rpm and after that the car starts to wake up.
Can it be because of the HPFP?
more than likely, i have the same problem on my audi a4 2008, i opened the hood while the car was running and the HPFP was shaking like crazy, I looked at it while the engine was off, and i see that it was missing 2 bolts, i guess it came off or something. But i am currently getting the HPFP replaced and the pcv valve aswell.
👍
So question. I installer my HPFP. Car fired up. I shut it off and tried to restart now it won't fire up.
It may take a few cranks. It has to build up pressure, around 700 psi or so, to keep fuel pressure. Possibly you had residual fuel in the line to kick it on once? It helps if you have a scanner with live data and you can watch the fuel pressure build in real time.
Those shiny pliers told me what I needed to know really my friend let me tell you modern cars have A LOT of shit going on even in the dealership with manufacturer manual and $50ks+ worth of scanners sometimes it is really hard to pin point the issue for us
You can easily spend years on UA-cam searching this and that replacing half of the engine and getting no where
If only you’d know how many cars we see the owner tried to DIY it and either has done things with no effect or made everything worse
Also didn’t you say you’ve done compression test and there’s been a low compression in a cylinder!?
I assume you haven’t don’t leak and/or wet test otherwise at least you’d know if there’s leak from valves or ring!!
I know HPFP if absolutely rubbish on CDNB and it’s a good idea to replace it (with fuel pressure sensor) but in %99 of the times it ain’t gonna fix this engine’s legendary miss fire
I hope you haven’t waste your money on new plugs , coils and timing 🤣
Was it it misfire before removing
It was misfiring randomly. I ended up pulling the motor to rebuild. I also found there was a stuck open fuel injector.
@@elvrolet I’m going thru the same problem of just 1 cylinder missfire, everything has checked out good from compression to leak down to carbon cleaning & injectors my last resort would be the high fuel pump and follower
Could of just unplug the battery
FIGURE IT OUT?
I ended up pulling the motor and replacing the pistons/rings. Ran good after that. This motor had previously been "rebuilt" by a place in california. They used cheap pistons/rings which seemed to be causing the misfire/rough idle issues.
I got 2009 Audi A4 126 k same problems oil consumption plus misfire problems
@@elvrolet why someone would go though the hassle of pulling a motor from a car and using cheap parts that are not even that much to begin with I will never understand
