I recently contacted Daihatsu UK about the "pinking noise" on the K3-VET engine.
As expected they deny any knowledge of the problem, saying there had been only two Technical problems back in 2002.
The first was a rattle from an air hose and a screech from wrongly tensioned serpentine belt.
They dont even admit to the rear anti-roll bar bracket failiure or the rear exhaust section that falls off!!
They were quick in correcting me when i said there was a "known fault with the DVVT unit", after listing the faults above they ended by saying "therefore in terms of a known fault with the DVVT unit on the YRV model, i would have to respectfully disagree".. They also assume the noise has not got worse, caused any drivability or reliability issues.
I know my noise has got worse, more so on cold start. Regards the latter, who knows i dont do many miles and at just 28,000 i think its still early days yet.
I have not touched the small pencil filter mentioned in a previous post just yet, dont want to be accused of tampering.
I have replied to their letter and apart from saying alot of owners have the same noise problem etc, i want them to confirm if the "pencil filter" should be checked/cleaned by the dealership mechanics on oil service.
I have a feeling the mechanics dont even know its there and is maybe the cause of the noise or caused damage to the DVVT to create the noise.
I always use Comma engine flush every intermediate oil change i do and even pop some in before it goes to the dealers too, so my filter should not get blocked.
I have the Turbo specific service and technical manual and there is no mention of service on the VVT filter but it does show the VVT filter in a picture of the engine showing oil flow of the internals.
Like me i know alot of you have also been to the dealership while still in warranty about the "noise" and been fobbed off with all kinds of excuses.
We need to stick together on this and force them to sort it out.
Please come forward and say if yours has the "noise", with your permission i would like to present them a list of owners so they can see this is no isolated problem.
