Ecu T4

[T4spanish]

My ecu gives me problems and I want to buy another one from 1998 but I would like to know the reference number since I don't know if the one you have installed is the correct one for your year

Are you aware of verlog codes ? An Ecu from another car will not work unless you clear the Verlog code first still fitted in the car it was working with . , when you plug it in the other car the CEM loads the verlog code into the blank ECU.

I bought my car second-hand and it already had breakdown light problems and hot start problems, the ecu was tuned and I really don't know if it has the right one for the same year, so I want to buy a used one but I don't want to be wrong year, when I bought it, I will have to take it to the tuner to make it work in my vehicle, but I need to know the reference so as not to make a mistake in the purchase

auto or manual transmission ?

from what you say it sounds like low fuel pressure , pumps do fail after 100.000 miles


ECU
Manual = 8251350
Automatic = 8251580

It is manual, I have a walbro 255 lhp and then I tried again with the original and it continues with the failure

,at first glance, the year 2000 and 98 are the same on the outside, even the pins look the same, I can't see that reference in the ecu, I get many numbers
