wjw Posted December 5, 2009 Report Posted December 5, 2009 (edited) I am experiencing sluggish starting on 1.9Tdi 110bhp Mk1 T plate. The duration of the glow plug light on dash is very short - even when ambient is -1 Edited December 5, 2009 by wjw Quote
big_kev Posted December 5, 2009 Report Posted December 5, 2009 Its just cold and your battery is less than perfect. My 1998 R reg starts instantly most of the time when the battery if fully charged.if I have been running locally with the lights, heated screens, seats, fan etc all full on it can take a few seconds to start the next day. The glowplug light only ever comes on for a second at the most. Quote
seatkid Posted December 5, 2009 Report Posted December 5, 2009 (edited) The glowplug light only ever comes on for a second at the most.Not true, BK! The glowplug light comes on for only a second or so if ambient temperature is greater than about 6 deg C (gestimate) or the engine is at least luke warm. However below this the light stays on longer and longer. At -1 deg C and stone cold engine I reckon it would be on for about 4 - 5 secs. At -20 deg C it stays on at least 10 seconds. That is my experience anyway. It appears to be controlled by combination of external air temp sensor, engine coolant sensor (this is a multiple sensor device) and ECU analysis of very recent engine activity.

Mirez Posted December 6, 2009 Report Posted December 6, 2009 Whilst what you say is correct... At -20 deg C it stays on at least 10 seconds. That is my experience anyway. Where the hell have you been! ;) Quote

Mirez Posted December 14, 2009 Report Posted December 14, 2009 You'll be able to see what temperature its reporting if you have access to vag-com - would be insteresting to see! Quote
