Hydraulic Lifter Replacment

**Jmac** · 22-07-2014, 07:05 PM

I did try and give as much advice as poss on what was found at the time of test giving it I found the noise to be in conjunction with the roughness. Anyway I did also mention good will as well during the chat and its worth asking worst they can say is no. There is a few tools reqd to set up the chains on these and I haven't as yet geared myself up with such as I haven't seen enough with problems to warrant having them yet, and as many were sorted out in their warranty period. They did have a superceded chain tensioner but a few I know of came to a halt quick smart amd didn't last as long as yours has been going on. Any stretch or misalignment generally throws a cam to crank correlation code but has to be bad enough. I had the chassis ear on it and when it happens its pretty widespread and hard to hear, it could be transferring. It would be an idea to ask VW to see re your vin if your engine has the older tensioner and if yes then pull on them for the campaign, as like I say there is a bit involved in doing the job. As these get older ill no doubt have the timing gear but hasn't been worth getting it to date. see how you go, I don't get on here as much so pm on FB or txt if reqd. And for the record its not coils and its not fuel pump , pressure is spot even during roughness . And also for the record I personally think its a waste of time using R8 coils on MK5 or MK6, I know of plenty VERY quick VWs using std VW coils, im sure Guy still has Std ones in his Mega quick MK6 so stands to reason. In my opinion its under bonnet bling

Car still pulls hard. I've just noticed though that the car when still will not rev past 3800 rpm's this is new to me or I've never noticed it before..... When driving I can still red line it.

Revving at standstill (in neural or P) you will only be able to rev up to 3800 RPMS.. This is totally normal, it's the ECU being smarter than you and preventing damage to the engine. Don't stress about VW goodwill, 1 year is not long at all, I have seen VW bend over and let you stick it in no lube required some of the 'goodwill' they have done, e.g: customer not servicing TDI passat for over 55,000kms, oil galleries blocked up causing damage to main conrod bearings, goodwill cover 80% parts and labour for new engine, passat in question was a 08 model getting 'goodwill' work done in 2013...

I can't thank you enough Jimmy, with out you taking some of your time for a look and listen I would not be any closer to a resolution. I brought up the subject of the lazy lifter as my usual mechanic mentioned this and after the oil change the noise seemed to be more from the side of the engine closet to the timing chain. Rather than across the whole block.I think there could be a number of possibilities. I've got it booked in to VW and I am seeing Gavin for a few more tests to see if he can eliminate a few things. I'll let you know how things go. Thanks again.

Just an update for anybody who's interested. I'm just trying to find as many symptoms as I can to go armed with to VW. Just noticed that it coughs and stumbles at around 1200 rpm with a engine rattle and when rev up it quite tens down and stumble stops. Just noticed that it will not hold 1400 rpm's. When you rev up it stumbles T it point and when you rev lightly further nothing happens until you get to a certain point and then it picked up and revs to the throttle position you are at. It's almost 1400 rpm is a flat spot. The same happens when you let off the throttle a little, rpm's drop slowly gets to 1400 rpm's themselves drops suddenly to 1200 rpm's and the noise starts and car stumbles. This is also noticed when driving, setting off slowly pushing past 1400 rpm nothing happens and then once you've pushed past this point it picked up.

Not sure that I'll have much more to offer after what Jimmy has written above. Seeing as he makes living out of it!

Getting the revs to hold at any given point on a fly by wire throttle isn't easy. So I personally wouldn't put too much emphasis on that.

Hold the revs at the point when you show them at the dealership, its pretty obvious, even if it didn't have a roughness there is a noise there that shouldn't be. I agree with "The One" above with regards to the goodwill, id be pulling on that for sure, it sells them cars in the long run

The plot thickens. Not at VW until Wednesday but just been playing and noticed that when sat still with the clutch pressed it coughs splutters and shakes and the engine rattles. When I let the clutch out and don't move the accelerator within 5 seconds the noise stops and the car is smooth again. This is all happening still between 1100 and 1400 rpm's. I still get the little stumbles at low rpm when driving and these are a lot worse when the oil temp is cold. I'm getting more and more confused, hope VW can make me happy.

How do I change the title of this thread?
