Will do that tomorrow. What do you mean by trimmers?

There are a few adjuster (trimmers) on the left of the circuit board. I like to see the settings for your car.

Here are some pics. I hope that the circuit picture is clear enough.

The pictures are ultra clear, very nice.
The circuit board is properly solder linked. The board was manufactured in March 2012.

Please give me some history of this system,

1. The system has been on your car for a number years? Has it been working well up to now?

2. Does the gauge show lower flow than normal after you have repaired the leak?

3. Any maintenance done on the in tank filter, nozzle pattern etc?

Please help me with those questions.

Hey Richard.

The system has been on my car since December 2012. It has been working but not 100%. I faced many leaks thought the 2 years I had the system. Few installation mistakes with resulted in that TBP leak. Sometimes when I get meth flow, failsafe activates for a second the deactivates, the activates again and so on. At first, I thought it's normal. But seems not anymore.
From how much leaks I had, the bottom of my tank enclosure isn't black anymore. And the trunk mat smells of meth as if it has been soaked for years with meth lol.

Flow is usually normal. Never seen low level of flow. And again, I added an epoxy to the outer section of the level sensor to block another LEAK. That's the only mod I did I gues.

I like to address a common issue on the VW. Interfere causes the gauge to flicker sometimes mistaken as real flow.

I like to make one modification on the green harness (user port). Slice open the vinyl sheath as close to the RJ12 connector as possible. Pick out the white wire and cut it in half.

This wire is not needed on your setup. It sometimes picks up interference from the red and green wire of the Di fuel injector. Let me know how you get on. A picture if possible.

What type of tank do you use? Do you use our tank adaptor that comes with the kit? It has a similar seal as the water level sensor. If it was over tighten it will develop a split in the long term. A replacement gasket is needed.

Shipping by post is very reasonable.

I did the white wire adjustment. All what happened was no flow at all. I was surprised to be honest coz I know that it's not used in Tsi setup. So I had to solder the wire back again. Strange..

And all of my setup is from Aquamist as here's no compromise in quality. But I unfortunately, the installers were bad in my openion. I'm trying to get fed up with all this.

Keep the white wire cut.

Can you do a manual "SYS" test with the jet out and engine running. Just a second or two to see if the gauge shows flow.

We are going back to basics

We have no control over the install, Your controller looks brand new. You do look after it well.

I can do anything if it will make it work. Let me know how they test is done step by step please.

Shall I put the jumper back to CLP?
