Dealer found my methanol lines, didn't care

I had belts replaced (both? I only know of two). Anyhow, they removed the inter oiler piping between my inter cooler outlet and the throttle body, and I had hid the boost tap and methanol injector rubber lines as best I could and black electrical taped them out of sight. I went to reinstall today and they had basically taped them back for me after they did the belts. No one mentioned it but my car was at the dealer for three days for an oil change and new belts. Weird. There's also a note that says the shop foreman good willed the fan belt replacement since my warranty just expired 9/1. I'm still under cpo warranty.

Just wanted to share the results. Nothing worth noting except that nothing was mentioned. Could've been bad.

They generally dont care if it isnt related to the problem. I had a catch can installed for ages and clearly sitting next to the PS fluid and heater hoses about. SO long as it doesnt impede repairs or be linked to damage youre golden. For example injectors have a problem then theyre going to question why theres a meth bung, catch can, etc etc. Like right now i have a M3 steering rack. They most likely wont give me a new PS pump if it goes bad and they sure as hell wont give me a rack. lol but if my engine explodes, diff falls off or transmission takes a dump ill them replaced.

That's what makes sense to me now. They're just doing their work... Wouldn't be surprised if there's a note on my VIN over this though. I may bite the bullet and buy a new inter cooler to throttle body pipe just to be safe, especially if something worthwhile happens in the future. I think it's a good investment.

The charge pipe i had thought about it but removing the lines should suffice. If not a new pipe couldnt hurt haha.

I had considered Meth but wanted the virgin charge pipe as back up if i needed to take it in. I'm sort of at the no turning back point now with the DPF/EGR/SCR deletes in place. Although the EGR isn't truly inactive. With EGR cooler completely removed, I'm okay even though EGR cycles (see Yozh video). I'm thinking meth would be my next logical step to clean the crud out of my 32,800 miles driven prior to EGR reconfig.

Car still pulls like a beast and gets great mileage (41 mpg if going easy on freeway) so I'm hoping i've caught it early enough to not be CBU'd.
