On my Golf that 100 from your picture which is A1 on diagrams.

Can be various numbers.

Terminal 30 Input Relay (J317) 109 458/100 207 219 643 644

On 2007 Golf GT 2.0 TDI-PD.

Terminal 30 Input Relay (J317) 100 458

Relay code number 100 is replaced by relay code number 370 depending on production.

That is an ebox low, I have just serviced an identical car, this is it's box which is also eBox low even though it is a specked up Highline



I was going to try and explain the ambiguity in ELSA but lost the will to type... so I looked to ETKA for inspiration and that says the number is 644! Plot, lost.... The trouble is I have too much to do today to unravel it all. Using the VIN of the car I have here, (Golf 6, 2009 CBAB) ETKA FI Suggestion states that position 1 should have a 644 relay part number 4H0 951 253. The realy in this one is part number 7M0 951 253 A and it is AE brand from 04/09 which means it is the factory fitted relay made by Auto Europa originaly designated for a Sharan and AE made the Sharan 7M in Portugal, this is Italian! Confused you will be! So the relay it has is 7M0 951 253 A and it should have (according to FI ETKA) 4H0 951 253 but if you put the &M number into ETKA part number look up, this changed to 4H0 951 253 on 01/04/2010 and indeed has 644 on top.

I'm going home, it's 32 degrees in my hovel...
