Hello everyone. I’m a bit stuck with a self diagnosis of my issue here. Before I explain, here’s what is done to my car;
Intake, charge pipe, catless DP, valvatronic exhaust, E50 and 91 maps on ECUTEK. Other than these engine mods, it’s all stock.

I have a somewhat major gasoline smell coming into the cabin from the AC whenever I’m at a stop. With the hood open, there’s a blow of hot air coming from the turbo area with a scent of exhaust fumes. At first I thought it’s the catless DP even though on E50 I never smelt anything like this but after switching to 91 map, I started to notice a smell and surely enough a week later I got a CEL. Code 190302.

Here’s what I think so far. I know it’s not my gas cap, I know it’s not an actual fuel leak because my MPGs have been very good the past few weeks,
it’s either the downpipe/turbo connection, the seal where the manifold is as shown in the picture, or my charcoal canister is full.

I notice the hot air coming from around where the manifold/header is on the turbo side as shown in the picture and am worried maybe my gasket is toast and it’s leaking air. What can cause this code?

I do shoot massive flames occasionally but haven’t in a long time and this popped up after switching to my 91 map for the first time to save on gas since I commute to work.

I want to see what you guys think and think I should try doing before throwing stock parts back onto the car and taking it in under warranty.

Please and thank you! :cry:

Um…. Did you notice the HUGE crack in your manifold or are you trolling us right now? Picture 3…… at first I thought it had to be a shadow, until I noticed the uniform fitting of you pushed them together….

Brotha you had me shittin bricks for a second. Ran to my car to check. No that’s not a crack, it’s the shadow. That raise is apart of the manifold/turbo

Haha you see my blown up view of your 3rd picture, I looked at it multiple times, trying to see if shadow or crack. That’s 1 weird shadow then with the fine point, haha. Well, I’m glad it’s not cracked.

DP to turbo gasket blown out?
I believe it might be this. Felt some hot air coming from that area but no visible smoke/evidence of exhaust fumes coming out, I’ll check it because I feel like this is the case.

Were you able to fix the issue? I’ve had that same code “190302” before but never noticed any smell. Last two weeks I have been getting a faint smell. Until yesterday, was way too much. Also seems to be coming from the vents. Like you, my MPG still the same. I too have a catless DP, tune, Visconti flex fuel kit. Check the hose from the FF kit but didn’t see any leaks.
