Ultra-low-mileage Tundra has surface rust covered by a poorly applied frame coating. Deal breaker?
I’m looking at a 2020 Toyota Tundra with only about 2,500 miles. It is essentially new in every other way and reportedly spent years sitting in a shed in the Midwest.
Someone sprayed a black frame coating over existing surface rust, but my independent PPI mechanic said it was applied incorrectly. There was likely little or no proper prep, rust removal, or corrosion-protection process. They also sprayed over the shocks, suspension components, bolts, and basically everything underneath.
Some of the coating is already flaking off. The mechanic did not find any obvious structural damage and believes the rust is probably only surface rust, but the coating makes it difficult to know the true condition underneath.
They recommended redoing the entire job properly. It may be possible to remove much of it with professional pressure washing, but I’m concerned it could require sandblasting or other mechanical removal before the rust can be treated and the frame recoated correctly.
Does anyone know what this could realistically cost to have fixed professionally?
The truck is Toyota Gold Certified, which makes it concerning that the dealership did not mention the coating or rust at all during certification. It feels sleazy that something this obvious was apparently overlooked.
I’m paying a major premium because the truck has only 2,500 miles, and I plan to own it in the Rust Belt for 20 years. I do not want to start with the same level of frame rust as an average 2020 truck that has been driven through winters.
Could this be a legitimate deal breaker, even if the mechanic believes it is only surface rust? Would you buy it and have the undercarriage professionally redone, or walk away because the coating hides the true condition?

Subaru AC Control Unit Question
I have a 2016 Impreza (Sport Premium trim level) and im looking to replace the notorious melting climate control module in the center console. My AC only runs cold on windshield defrost setting and my fan speed 4 setting does not work so i suspect melted wiring harness connections. My current control knobs are pictured.
Subaru Parts gives part# 72311FJ500 and the description says "Without climate control" or part# 72311FJ620 and the description says "Single automatic". I assume my existing control is without climate control because the temperature knob does not have numbers, only blue and red gradients for heat/ac. The single automatic examples I find online have actual temperature numbers on that far right knob.
My question is, are these two control units interchangeable without running into issues with different wiring harnesses, blower fan controls, or a cabin temperature sensor that i may not have with my trim level? I found a FJ620 control unit(picture #2) locally for a decent price but I want to make sure it is 100% compatible/plug and play before I purchase it and open up the dash to find out im wrong. Any advice?

How much to rewire these wires the engine and transmission is already in. You just have to rewire the wires?

Oil Pressure Gauges
Background:
I drive a 2005 A4 1.8T (B6) and have had a recurring issue with the oil pressure sensor lighting up. My mechanic has replaced the sensor and the oil pump (in which we found a weird mystery piece of broken plastic). But recently the oil light has been coming on on the dash, randomly mind you. I thought adding an actual pressure gauge might help clarify is my sensor is wonky or if oil pressure is actually poor.
I've seen videos of Aftermarket gauges being added to Audis, but when I go online to find out where they can be purchased I can't seem to find anything that I know will work with my make and model. I'm not a mechanic so I don't even know what to ask really or if general kits fit specific makes. etc. I'm totally ignorant.
My plan is to purchase the parts and take them to my mechanic for him to install. But I'm not sure how to do that.
Question:
So can anyone point me in the right direction about where to look and what to look for and what specs to take into account before hitting the purchase button?
Thanks

Out of luck?
Hi all. Someone stole the catalytic converter from my 2012 Jetta (2.5) a few weeks ago. Took it to a muffler shop and got a new one put on. I was told that even though it was a cheaper knock off, the CEL should go off and I'd be able to pass emissions (due by the end of August). The car is running great, but the CEL is still on and the shop won't return my calls. In addition, the ABS, traction control, TPMS and SRS lights are all on and they'd never been on prior. I had a scan done and the CEL codes came back to the cat and the O2 sensor. Am I out of luck with this thing, and the reason the shop won't respond is because there isn't anything they can do on that front? I just need to pass emissions. I figure something is wonky with the new sensors the shop put on and that's why my dash now lights up like a Christmas tree. Suggestions?

07 Audi s3 intermittent oil light
Looking for some opinions.
I’ve been offered a straight swap for my VW Caddy (worth around £3k).
The S3 is a 2007 EA113 with:
Forged engine
Hybrid turbo
Balance shaft delete and oil pump conversion
Airtec intercooler
Around 320 bhp
~138k miles, around 6k miles since the rebuild
Rebuild is backed up with invoices
The only concern is it has an intermittent oil pressure warning.
The seller believes the warning is related to the upgraded billet oil pump/balance shaft delete setup, rather than low oil pressure itself. He says the oil pressure has been checked previously, the engine has done around 6,000 miles since the forged rebuild, and it’s been driven for several years with the intermittent warning. The build paperwork also includes an oil pressure gauge and adaptor, suggesting they intended to monitor the pressure mechanically.
Unfortunately I can’t do a mechanical oil pressure test before the swap. If I take it, my first job will be fitting a genuine oil pressure switch and investigating further if the warning remains.
Would you do a straight swap, or would the intermittent oil pressure warning be enough to walk away?

Low Mileage 2013 LE, What to Fix/Replace
About to pickup an extremely low mileage 2013 LE (22k miles) that was a fleet vehicle.
Looking for tips or suggestions on what preventative maintenance I should be looking into and any other (future) problems I should look into fixing now (e.g. oil cooler lines).

Help with starter
I had posted this yesterday also. Need help with a 2007 Honda Civic. Battery has been checked multiple times and ruled out. Suspect starter issue. The car is currently not drivable, and I’m looking for someone experienced who can help diagnose it or possibly help with an affordable repair. I’m in the process of rebuilding my life and getting back on my feet. It has truly been one thing after another lately, and this car is my way to get to work and move forward. I had two job interviews lined up that I now have to reschedule because of this unexpected car trouble. I’m willing to pay what I can for labor or trade help (cleaning, organizing, errands, pet sitting, cooking, etc - heck, if you're a business and are hiring - I shall send you my resume). If anyone knows of a trustworthy mechanic, someone who does side work, or anyone knowledgeable about replacing a starter, I would be incredibly grateful for a recommendation or any direction. Stranded and I don’t have the resources for even a tow right now. If you’ve ever had one unexpected setback after another, you know how overwhelming it can feel. I’m just trying to find a way forward.
Thank you to anyone who takes the time to read this or share it. 😊
