So to start off with I bought a low milage used 2019 fiesta st from a dealership back in December. 26k miles to be exact. Car had upgraded intercooler, exhaust, rear motor mount and air intake. As well as a few cosmetic mods done.
About 2k miles later a check engine light, code p0299 turned on for low boost. I cleared the code with my scanner tool but it still gave me a "permanent" code that would not show on the dash. Anyways, I took it to the dealership (at this point there was no check engine light on) but I had told them it had a "permanent" code. The technician somehow cleared that "permanent" code and test drove the car for a good 10 miles and said all was good and that the car was running perfectly fine.
Took the car home and all was good until the check engine light came on again. A few hundred miles later.
To be honest I rather not deal with the dealership and just do my own work myself unless I really have to take it in.
I lifted the car and checked all connections and fittings.
I still hear the turbo spool up perfectly fine but noticed the intercooler piping itself was still stock. Stock and super squishy. If the intercooler is pulling in air, and the piping collapse on itself, would that be enough for a CEL to come up?
The Service adviser told me the light might have came on because the car has upgraded mods with no tune.. and that may cause a CEL? Something about a lot more air coming in and the ecu not knowing what to do with the extra air.. seemed plausible to me but not sure.
Any help would be appreciated.
If I need to buy an accesport to tune the car I'll be doing that. Just want to get peoples opinions first. Thanks
