Hi all

I'm new on this forum, so not sure what the protocol is for a first time post. But, glad to be a part of the community. I'm from South Africa, based in KZN.

I hope you guys may be able to shed some light on the issue I'm having with the Anti Shudder Valve on my car.

Its a 2006 Seat Ibiza 1.9 TDI FR. A few months ago, I noticed that the car suddenly has a shudder when turning the ignition off. Its never done this before.

Ever since that day, the car has this shudder. I've checked the ASV and it moves freely manually. No obvious dirt or build up.

I've used a mates VCDS to perform the output test on it and the car shuts down perfectly, no shudder at all.

However, I go back to using the ignition and the shudder is back.

I cannot see any damaged wiring going to the unit and there are no errors present on the VCDS scan.

Is there anything else I should be checking or any idea what could cause this odd issue?

Any advice would be appreciated.


(Note. I have an electronic ASV unit)
