Title: blue temp sender
Post by: siddleg on 04 December 2011, 18:47

alright all i need some more advice

i changed the sender hoping to cure a splutter at low speed in 2nd gear whilst going over speed humps or around slow corners but now when i start it after a few hours of standing it struggles to tick over for a 30 seconds so unless i rev it then its fine.

the sender is brand new from vw and is black

whats going on?

So you've put a Black Sensor in the Blue Sensor socket???

So now you have 2 x Black senders??

Black sender - gauge only.  Can't affect running of car.
Blue sender - ECU only. Can't affect gauge. Badly affects running of digifants if dying/dead.

Only about £15 for the right blue one from the dealer,  025906041A.

SO if he has put in a Black sender on the blue plug there is no wonder he has running problems...

BTW - Blue senders are £15.94 plus VAT - Just bought some last week...

Post by: Santiago on 05 December 2011, 13:21

AFAIK it's only digifants that use the blue sender.

No. A kr possibly has a blue wire for  oil pressure sensor,as well as a yellow wired, white collared sensor, but no 'blue sensor' as on digi 8v. It has 3 black collared water temp sensors on side of head, the white collared one on back of head is mfa oil temp, and the two oil ones mentioned earlier are on the oil filter housing.

Poor Op he must be really lost now  :laugh:

I still think the one on the block was a over run temp sensor, but that was on the 8V Rallye I think? Could be MFA But I thought the side was MAF for the KR  :rolleyes: :laugh: :lipsrsealed:
