I wonder what is there for stripping engine, they must suspect siomething pretty serious going on??!!

Is either of your exhaust tips more sooty than normal? O2 sensors and injectors seem to be the usual culprits. I belive the O2 are much easier to diagnose with a specific error, where as the injectors are more misfire on certain cylinders, and in my case was most of them! If it is a recorded misfire...

Straight forward providing it doesn’t break and get stuck in head

Injectors

Careful if you disconnect or remove battery getting back into the boot!

Could you have a mobile detailer give it a quick go over every month or so so its not a chalkboard for idiots?

Leafblower is your friend!

If it was me i would just find a decent detailer and pay for a ceramic coating

My 10yr old could do a better job than these muppetts! Depending how much its overfilled it could cause damage so as mentioned be careful

I can’t come now, please take me off list Steve. Absolutely gutted

Good luck with the sale, how much is it?
