Had a ECU for sale and a fellow member said he needed a new ecu as he had problem with a pin on his ecu had corroded/melted.

so he said if he paid me £5 extra to 24hr delivery it which i done even tho it cost me £15 extra but i swallowed it.

I tested this ecu on my other car before i sent it and it was all ok.

Bloke sent me a message/pic this morning saying the board on 1 pin is melted/corroded.
the pin which he mentioned is a power pin and was loose so wouldnt work.

Now im all for refunding goods if needed but imo i think he used his ecu board and put it in my casing saying its faulty. i feel robbed funny how my ecu suddenly has the same thing as his ecu?

this was this morning and hes already put a complaint in to MarkyD or whoether on here.
its all too sus and setup to me.

so now he wants me to take this fucked ecu and give him his money back.?
