Greetings all> I'm new to posting into this group, so apologies if this is in the wrong spot. I have had a good look around what is s great looking forum, and can't find similar issues so here goes here.
I'm having a frustrating time with slow starts, and have done for some time. The touareg will start, but only after 10 - 20 seconds turning over. Then for the rest of the day will start normally. I live in Ballarat Victoria (Aus) summertime now, and a generally temperate climate.
Here is the last Ross Tech scan, engine running, (current mileage actually 161194??) after which I cleared the fault codes, and re ran the scan with no glowplug faults showing. The Central electrics faults also cleared - probably they showed up on one of the 20 second turnover starts?? As the engine was now warm, probably the computer said no need to even try turning glowplugs on?
I am thinking (and have ordered) a replacement Glowplug control relay, what do others think?

005676 - Glowplug Control Module; Supply Voltage
P162C - 000 - Open Circuit on Load Side

That's a new one on me which I've added to may app. As there is nothing on google it

Which will be the same as the old one.

VAG Error Code: 17068/001668/4996

EOBD II Error Code: P0684

Fault Location:
Glow Plug Control Module (GPCM) (J179) - Implausible Signal

Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Lack/Loss of Power.
Engine may be harder to start.
Engine hesitation.

Wiring/Connector(s).
Glow Plug Control Module (GPCM) (J179).
Engine Control Module (ECM).

Possible Solutions:
Check/Replace all faulty Wiring/Connector(s).
Read Measuring Value Blocks (MVB).

As taken from my new Free EOBD II Error Codes software

Hi. Have you had any joy with your first start.
I have a similar problem though I don't have any relevant fault codes.
I have found though that if I disconnect the temperature sender on the back right hand side of the engine that the first start is much quicker.
I believe the computer is defaulting to a sub zero temp setting and supplies more diesel and perhaps changes the injection timing .
Please any advice is welcome.
Thanks.

First posts normally go in introductions else you could get a free fix and we never see you again!!!

Forum Rules and Guidelines

Any problems search TDI Wiki as that covers write ups and forum posts.

Disconnecting the coolant temperature sensor is a trick that's talked about many times in this forum.

You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

Good day, thank you for the message. Sorry, I was not sure if I had, and didn't know how to check if I had chatted on Myturbodiesel before.
Appreciate the help and info.

I had read this before somewhere.
Thanks
