My Alfa 2004 computer box one of the pins is burnt what can I do?

if a pin is burnt on any ECU engine computer
inside a diode may have failed

ECU incl ignition key for Alfa Romeo 147 1 9 JTD 115 hp 5 doors 2004 Bosch...

find a used or referbished unit with same numbers on the outer casing as your damaged ECU
the replacement has to be from the same year and engine type as your car and same number of pins and plug ins

auto electrician might have the equipment and time to referb it

when fitting a used ECU
you may need to re sync the system with a diagnostic tool

How to remove an alternator from an alfa 2.4 jtd

My best advice is to pay a mechanic to do it! Access to it is a nightmare! Jacked up with a wheel off and the wheel arch liners out!!
You will also possibly need to remove 2 auxiliary belts to do it. (Depending on if you have AirCon fitted). A longer, outer belt and the shorter inner 'stretch' belt.
The alternator itself is held in place with two bolts and the electrical connectors on the back of it. One large wire and one small connector.
One of the smaller pulley wheels will be on a spring loaded arm to give you the slack needed to remove the longer belt.
For the shorter belt you might need to slacken the mounts on the air conditioning compressor to release the belt. To get access to the alternator.

Hi,I have a Alfa 2003 156 2.4 JTD. All me warning lights came on and the mechanic told me that the battery and the diode box was shot. He replaced both. It lasted for about a month and the same thing...

Perform a voltage drop test across the battery (charge wire) circuit to the alternator. Corrosive or high resistance spots created in the fuse or path will render the alternator inoperable even though there's nothing wrong with the alternator.

My 156 sportswagon is burning fuel badly i put 2 gallons in and only got 31 miles for this i can hear an air leak coming from top of engine would this be a likley cause for such poor fuel consumption it's...

an air leak would weaken the mix of fuel to air so giving you better fuel efficiency but a poor power output.
was my last answer not to your liking, re **** fuel consumption on all fiat/alpha cars.but it is true, ask any owner........14.7 average mpg.......£205 road tax.....(tax it for a year and quadruple its value...)

VDC system failure on 156 selespeed

I have the same problem with my 156 2.4 JTD 2002...two most common reasons are:
-steering angle sensor ( "U shaped, black thing" on your steering column/wheel

has a lose connection or needs to be changed )
-old battery ( sounds stupid but new battery solved the problem in many cases)...it could also be an alternator problem
I've checked my car with FiatECUScan and it says...see pictures below...

Good luck!

SOURCE: new alternator fail

If it was rebuilt, could be it was just not a complete rebuild. Some remans are just fixed and cleaned up. Some are completely gone through and good as new. You should have a warranty. Most good remans come with a lifetime warranty or at least one replacement as long as you own the car..
