My silver RS2 Project

[Tractor Dave]

Yes.
Still no luck.
I was really hoping to find a broken wire under this damage.


But it was all good.



I have a small hand held oscilloscope that I can test G40 output with but the battery was flat as it hasn't been used for a long time. It should be charged up tomorrow.

So did you have another go after your tea break??

[Tractor Dave]

So a rather frustrating day in the garage.
I swapped the ecu with the Nothelle to see what would happen.


Still no start.

I pulled a plug and it's dry.

I have voltage with ignition on at the injectors and at the coils.



I have fuel pressure at the start of the fuel rail.

So I'm thinking it must be g40. It's new so either it's not correctly positioned or the wires could be damaged.

Tea break then back at it.

Thanks. Someone might find it helpful one day.

The rest of the alarm came out without any major issues. Unfortunately, it only cut into the ignition so I won't have solved non starting. The ignition switch was a mess.





Then I checked the key. It would appear to have a chip.


Had a peek in the ecu while it was out.


Pulled the cluster and gave the contacts on the immobiliser module a good clean.


During lunch I renovated the gear change leather. It was very dry and badly scuffed in areas.




And the inside got fed.


This lot should shave 0.3 of a second off 0-60. lol


Whilst crawling around the drivers footwell I decided this needed to go.


Fortunately I had a very good spare from the cabbie I broke a while back.



I shall have another go starting tomorrow.

This is just the best pictorial ever David!

I googled the alarm and it's actually a good quality system. They are the same company that make the ghost immobilisers now.

This looks like carnage but it's actually going quite well. So far I've traced 80% of the wires where they cut into the original loom.

Thanks. I will let you know. There is a small immobiliser type connector in the centre consul that i dont have the key for. I need to investigate that as well. Unfortunately, this car has been off the road for nearly ten years and the last owner sadly passed away after booking the car in for restoration, which was partially done.

If it's the factory immobiliser that's holding you out it'll illuminate the immobiliser (orange) light in the cluster to show you that it's active. It should let you start and then run but only momentarily; you've not got long before it cuts you out.

As mentioned earlier, you can get around the immobiliser by loading the non immobilised software version in the ECU but there's also another way to bypass the immobiliser without changing the ECU at all.

PM me if that turns out to be helpful and I'll let you know.

If it's the same as the S2 Avant there's a chip in the key and a sense coil near the ignition barrel, the little two pin connector in the wire to the sense coil can have a bad connection, you could try popping it apart and clean the pins. IIRC the wire is about 20 or 30cm long so can be hidden up behind the dash?

Thanks. I will give that a try. Just also found that on the Rosstec site.
I only have 1 key with the car. It looks to be the main key.
I was expecting the car to fire up and cut out with factory immobiliser. I think they may be another issue preventing initial start as well. I'm going to do some more tests tomorrow and maybe try the Nothelle ecu to rule out or in factory immob.

Or yes it could be an aftermarket alarm immob install going wrong..

[newsh]

Or are you using a copy key without the chip?

So after a little head scratching I discovered that the ignition lights came after the car remote was used to unlock the doors. This allowed me to turn the engine over and hopefully build some oil pressure. I say hopefully because the aux gauge isn't moving. Nervous grin.
So then the plugs went in.



Fuel tank connection re connected.
Got the phone set up to hopefully record first start. Unfortunately, not playing ball today. Engine turns over but isn't firing. A quick check revealed I have good fuel pressure at the fuel rail but the injector's aren't operating.
Out with vagcom.



So we do have an immobiliser issue. Beam me up Scotty.

Yes had this before where it starts momentarily then cuts. I tried fitting an immobiliser ecu to my 93 car and learnt the hard way
