Hey everyone,

I have an issue with my car where I lose boost around 3-4k RPM, and then it starts dropping. I'm not sure where the problem could be – maybe there's a boost leak somewhere or possibly an issue with the N75 valve. I've attached some logs as well, so maybe you could spot something I missed. I'm just looking for ideas before I start throwing money at things like a new N75

Any help would be appreciated!

Thanks!

Thanks for the reply.

I forgot to mention that I had the car running on a Stage 1 AWT map before, but now I crossflashed it to a TT180 for testing (edited for my injector and maf size), and the result is the same so it is not the tune at fault.

I also forgot to mention that im getting the code "16395 - Bank 1: Camshaft A (Intake): Retard Setpoint not Reached (Over-Advanced)

Do you think the cam chain tensioner or cam position sensor could be causing this?

I'm investigating the issue and asking for ideas on what the hardware issue could be before I start throwing money at random parts. Can you elaborate on cam failure? When looking up the code on google, many people reported getting it while their car ran completely fine, so I am not even 100% sure it is related.

Good job on being one of the most arrogant and least helpful people on the forum.
How about telling him which worn or failed parts could be causing his "cam failure"? It's obvious that the first symptom he noticed is the loss of boost, he never said he's looking for map edits to look for "more boost" but for advice on what to check hardware wise, this was obvious in his first post when he said "boost leak somewhere or possibly an issue with the N75".

And yet when he replied to my post a while back after I explained what the actual situation was, he spewed nonsense about unplugging a TCU in a manual b5 and being incredibly arrogant while at it, same as here.

I didn't say he needs to fix or diagnose his car over the internet, but he could have at least said "could be X, Y or Z" instead of saying "your engine is going to blow up and you're looking for boost", such an idiotic arrogant response, literally would be better to just ignore the post than to write anything like that.

And keep being arrogant to "new worthless" members, it's a nice running theme in this forum that big members are incredibly unwelcoming. I may not post a lot but I've done my fair share of things surrounding the ME7 (Including reverse engineering in IDA) and other VAG electronics in the hobbyist fashion. Not everyone is going to be a professional earning money from this like many big members here, does that mean you have to call the people looking for knowledge "worthless"? Read up on some etiquette books.


covered countless times but not the actual difference between writing with 800BB or writing without the suffix. I've also searched on how to detect which memory layout a file uses from the actual file (as someone in the post which I necro'd recommended) with no results. All I've gotten from the post that covered memory layouts it is that BT was not used in production and can be safely ignored unless an ancient physical chip has been installed on top. The only reason I was doing all this anyways was because I was trying the Nefmoto Flasher instead of MPPS.

Why am I even telling you this? It's not like you're going to respond with any useful info, if you would want to do that, you would have done it in the post where I asked, but you're too proud of your knowledge to share it. Must be hard acting like you're better than everyone else all the time except your little elite club of non "new worthless" members.

I have already given him my input on what the problem could be (boost leak and n75 were my ideas) and I told him to ask here for advice from more technically knowledgable people who are also used to looking at me7 logs. I guess I should have also expected useless arrogant replies like your own and should have warned him about that. What makes me sick is the way you talk to innocent people looking for help on forums.

I understand 100% he shouldn't be pushing his car at this point and rather taking a step back and fixing his hardware issue, but that is the point of the post, he's not asking for a magic tune that will make his issue go away, but stating what his symptom is (boost loss) and asking for ideas before randomly replacing parts that could potentially be at cause. Someone who has seen this type of behavior on a log before could definitely say "I've seen this exact behavior before in a log and the cause was a defective X". If you don't know, why pop in and bring your smugness with you?

And thanks for a nice click of negative karma out of spite for just telling you how it is, I guess there's a first for everything, you can only take so much of people acting better than everyone else.

Full of yourself much?

well you didnt include wgdc.

But it doesn't matter, your boost isn't that far off requested.

You just aren't requesting that much boost. No clue what that tune is supposed to be doing.
