Code:
All (almost 100) scans of T5.1 (MY10-MY15) diesel engines in my collection are identical for this one - engine - byte 4 - value 23 = only 1 fan installed, only 1 electric water pump installed.


Based on the scans the byte 3 is "00" only for vans without AC. Vans with any AC (Climatic and Climatronic) have identical codings. Thus I believe the current coding is correct.
For the byte 3 only codings 00, 12, 1A exist. I don't know what's the difference between 12 and 1A (bit 3)

Hi
intersting as today i connected the bumper OAT temp connection, started the engine and the same the fan running all the time, i dont have access to the internet where the van is, 01 ENGINE ECU i went to long coding Bit 1-2 say 02 Bidirectional climate control installed byte 4 ) with 3 1A
This van has manual aircon ,Now changed to 00 No or Manual Climate Control installed Bit 1-2 Byte 4 coding excepted. Restarted the engine as in the Fan setup for Continous running 031 ) i had no choice but to leave that as it is unless i knew the coding Manually to change it Bit 0 - 2 Byte 4=23
The van started ok and the FAN is now OFF no running i have not run it to operating temp as work in progress but i dont see why it shouldnt cut in when
at the required temp.

My own Van Vw Caddy 63 plate has the same coding (02 Bidirectional Climate Control climatic installed, and continous fan installed, but it performs as it should approx 90d THE FANS CUT IN. but this T5 Not so with the same coding, My van has manually AC yet in the coding Bidirectional is set ,,not Manual
it has Manual fan for the heating and temp, i dont know fully what the difference is with Bidirectional , semi makes sense.
Do you know for the caddys Vans Can the Radiator fans using vcds be adjusted to run at a lower temp as 90 seems abit hot, especially when you arrive to park and ignition off, you have that thermal heat build up under the bonnet. i had a look today but could not see any means to alter it.
The T5 has Injectors faults listed Maybe that is causing the Fan to Run like limp home mode, but for now it is Off, and once the Van is fully sorted i can review its action then,

Can you explain where on the scan you saw the Byte 3 "00" information for AC and the Fan coding

Oops, the "00" should be actually "10" for non-AC vans.

Fan coding in byte 4 - always "23"

Anyways, for example scans of T5.1 without AC - engine coding byte 3 "10"

Scans of T5.1 equipped with AC - engine coding byte 3 "12"

Hi
I think i see how you know the coding as in the coding of the scans it is there if i look.
The van is ready for mot after a lot of electrical work, today checked the A/C set to 00 = 02 Bidirectional Climate climatic installed Bit 1-2 byte 3 ) 18.
I will make a note of 10 for Non A/C
And the Fan Bit 0-2 031 continuously Fan installed Byte 4 - 23 Seems ok it cuts in 89deg approx

Yeah, you want that set to 0 = Factory mode inactive otherwise various BCM functions will not work. Also note, Address 19 could be in Transport Mode (since it is new as well/part of J519). You may want to click the [De-activate Transport Mode] button located on the Applications screen as well.


If that doesn't help please post another current condition scan so we can see the overall condition at this point in time.

Replacement door latches (i.e. V56/F220) would be plug and play. No coding or diagnostic steps would be required.
Hi Dana
the T5 is all sorted, months ago,, just a quote id like to check with you Transport mode a vehicle i'm working on has Channel (1B ) Transport mode Stored Value Active
