They say don't go looking for a problem ....

Post by playback »

So .. Cars been running well. Can't complain. Feels good. No missing or issues.


Looking at doing a long distance trip so thought.
Since I bought a VAG Com.I thought.
Lets do some diags and lets see where she is at so I at least have a good base line....


I'll try link the logs. But HPFP looks absolutely terrible to me on the logs.
Done in 3rd gear. Was getting some spin in the mid range unfortunately.

https://datazap.me/u/dryreef/boosttimin ... &data=0-10
https://datazap.me/u/dryreef/boostfueli ... 0&data=0-8

Shes running a brand new LPFP.
Cam and follower were check at the same time after having been recently replaced.

Any ideas ?

Yeah that doesn't look good at all.

I'm assuming with the K04 setup you've also got a HPFP upgrade (hopefully a decent one), if it's dropping the rail pressure like that with an Autotech I'd be surprised, if it's with a Vortech, I would be less surprised.

With the rail drop your injection times are going way too long, 11ms is insane for a DI motor at high rpm. At that duration you are close to if not over the misfire threshold (although I don't see any reported misfire, but that might have been disabled by the tuner)

Log 'Current Fuel pressure' to see what your LPFP is doing, I didn't see that in any of the logs. If your low pressure is dropping to like 2 bar, then that might explain it, otherwise it might be a failing rail/pressure relief valve.

Thanks for the feedback @Thanas

Yup. Had a major oil starvation problem around a year ago.
Rebuilt the motor.
Then with lockdown
Reconned BWA head, all new bearings, new Oil pump etc.
New HPFP (Roughly 6 months old) VIS Motorsport Stage 1 https://www.vismotorsport.com/20tfsihpfpupgrade
Was installed by the Boys at DarkArtz as I wanted it done correctly.

What blocks to log for LPFP 106 ?
Any additional groups at the same time ?

I did log missfires btw. But havn't noticed any and logs came back as Zero.
https://datazap.me/u/dryreef/boostfueli ... data=0-1-8

Again. Much appreciated for the help.
BTW. Below is a link to the overall history of the car.

Thumbs up Thanas for such a detailed reply.

This though would worry me

Ok, Just got back from logging LPFP.
Couldn't see where it actually shows your pressure like 4 bar or 6 bar.

But Block 106 seems to indicate new LPFP that was recently installed is running well.
https://datazap.me/u/dryreef/test5?log=0&data=4
Idle live was 48/50% for Block 106.

Anything else I should have logged ?

Only thing I can think is the RS4 Fuel Pressure Relief Valve.
Don't feel like replacing it though if it's not that though.

None of the parameters in the latest log are the low pressure specified or actual values. You managed to capture the pump duty cycle, but you can't infer anything from that with certainty. Don't use logging blocks, go into advanced measuring values and search for each parameter individually. In this case what you're looking for will be titled 'current fuel pressure' as mentioned in my previous post.

In any case, 50 bar below rail target is cause for alarm, and you shouldn't be driving it hard until that's resolved.

Thanks. I didn’t realize there was another way.

Will try log tomorrow for ‘current fuel pressure’.

Ok, Logged the LPFP .

Not sure what the graph should look like but very shakey to me and with drops etc.
Going from 5.9 to 5.6Bar in places.

So car has been dropped off with Jared from JS Worxs.

ECU is being read by Michael from Thanas.

Let’s see what they find.
Hopefully something small causing big issues.
Unlikely I know.

I have a feeling a loong list is going to be coming back.

Ok, So car went under the knife again recently.

I initially at JS motorworx as I was previously told the follower was in good condition….

Then back to the original engine builder….

Not sure what it’s called. But think it the side came cover on the right that is an egg shape.
That had a large piece cracked out of it.

Looks like that damage caused or allowed the HPFP to “float around”
Thus destroying the Cam again & the end of the HPFP.

So a replacement have been sourced.
