ECU QUESTION

[DCha10]

Can anyone tell me what the last 2 letters on the ECU are for?

Are they interchangeable so to speak?

Mines CC11-12A650-AB and has been declared knackered thru water damage..

Have found another but the last 2 letters are "AC" but everything else matches.

Its not really a £350 gamble i want to take if its not correct.

Thanks in advance

The last two letters usually denote the "revision status" or latest update etc...AA ...AB ...AC etc.

Still have the old one somewhere...

Cruise is bcm not pcm

I always say the first is spec and second is revision. But you'll do an initialization pmi so the data from your original should be loaded to it

Cruise is bcm not pcm

I’ll get my coat...

Average price is around £120 mark, I'd be looking elsewhere if i was you mate

Bridge van do an ecu kit bcm,pcm an a key for 75 plus the vat provided that they give you the correct setup that matches your van and you don't mind the wrong chassis no on your modules it will run ok
If you do go down this route you should do pump& pilot learns /injector cal no's as these values are held on the pcm

Thanks for the reply’s...

Anyone selling one to fit my transit? 2012 model the only one I found on eBay that looked the same with the above mentioned numbers is the £350 all the others are a different looking ecu with completely different numbers

CC11-12A650-AB is for mk7 2.2 Euro 5 engines

CC11-12A650-AC will fit. BUT it will require to be reprogramed to your mk7

They are NOT plug & play. Even if you get one with matching part no.
Every van has different / optional features. It still require programming to your van.

Modules after 2010 will start getting tricky Paul because of the e4 and e5 changeover and also 2012 etis coded/incodes changeover too.

I would hope that cc11 means it is incoded access and eg. Bk21/Bk31 denotes custom and mk8?.

Any info that can be added to help the home user would be cool.

I know it will require reprogramming but was just making sure if i buy it and get it reprogrammed its going to work.....This van has been a pain! should have stuck with my faultless MK6.

Apparently the last 2 letters make no odds

But the 4VFB and S180145001 B are what matters...

So if anyone has one for sale or can point me in the right direction that would be great..

Thanks

Incorrect.

PCM part number is irrelevant. As it changes every time PCM gets updated & the new label never gets printed of & attached to PCM

4VFB is know as "tear tag" & Tear tag or PCM part number can be used for programming PCM with correct calibration for the vehicle it's fitted to .

Again that's irrelevant. As you are replacing PCM for a second unit & then programming it to your vehicle.
There for you can use either the tear tag or part number from you old PCM to program the second hand replacement unit via IDS.
Or you could simply use "As built Data"

Replacement PCM for your van as it's Euro 5. Should be SIEMENS / Continental & have SID 208 on the label.
