	Picked my car up yesterday, it's been stood for a few months and killed the battery, charger didn't touch it. Drove it home left engine running whilst filling up and got back, roughly 20 miles. Took it out when I got home, it started fine, went to the shop and when I came back out battery was dead, had to get a push start. Put a new battery on this mornin and it's turning over fine but no glow plug light coming and won't fire?? Any ideas it's a 1.9 TDI AAZ

	I think I've got one of those relays from when I broke my Mk3 AAZ. I'll have a look tonight.

	froggy according to a diagram I picked up off the web 109 relay should be the 3rd one. In mine there is nothing in the third port?

The old battery wasn't charging but the glow plug light was coming on

	If the engine is an AAZ, there will be no 109 relay as it's not a TDI engine. The 109 powers the ecu, which your engine doesn't have....

	Sorry for not getting back to you sooner on the relay, village is right, the relay you may possibly need is VW part number 1H0 906 123: www.ebay.co.uk/itm/NEW-AUDI-80-VW-GOLF-PASSAT-IBIZA-1-9-AAZ-ENGINE-CONTROL-UNIT-RELAY-1H0-906-123-A-/190940683072 There's also a big 50amp glow plug fuse that might have blown, iirc if it's not up on top of the relay board then it's in the engine bay on the nearside chassis leg.

That relay says its 136. I've took mine off and it's 166 but all the ins look the same? Would this be correct?
