Working on my prolonged starting time.
I have been looking in my "E" box too, which is where the glow plug ECU and relay are. Need some help identifying all the parts and also on any methods to test the function of the ECU and/or the relay. Want to check these are working before moving onto the glow plugs which require a bit more dismantling: 1. Glow Plug ECU 2. Glow Plug relay or other ? 3. Glow Plug relay or other ? Some more photos inside the E box
IIDTool has always given me this fault, prior to the poor starting
Price for new relay from Dan is £94, but this must be for the ECU (Number 1 in photo) ? Thanks . Experience is the only genuine knowledge, but as time passes, I have forgotten more than I can remember Volvo V70 P2 2006 2.4 Petrol 170bhp Estate SE MG Midget Mk1 1962 Previous: L322 Range Rover TDV8 3.6 2008; L322 Range Rover TD6 3.0 2002; P38A Range Rover V8 1999 |

I'd say relay - just sloppy terminology calling it an ECU

Well, the connectors are nothing like the relays in the howtos, a big single post for the output power and 11 small pins for the connector, and I couldn't get it off the little plastic board it is fixed to, but with finger on the relay and ignition switched to position 2 I can feel it click, then there is a quiet electrical crackling sound.

use multimeter to earth and top of glowplug should be about 0.9ohms resistance (iirc)

OK, carried out glow plug test today. Just to ensure i have the science right, removed connector from glow plug relay, then connected multimeter to +ve terminal of battery and inserted -ve lead from multitester into each of the connectors for each glow plug. A reading of 12v + indicates glow plug working OK.

Frosty this morning, 0 degrees, FFRR took nearly 15 seconds to fire up (chatata chatata ad infinitum!) so definitely glow plug related! .

It was all going so well, inlet manifold out, correct deep socket applied, then bang, the nut on the glow plug parts company with the threaded end of the glow plug, on four of them!! Really only applied medium pressure to undo, and gave some heat as well.
