Saw this image from another thread http://www.mk5golfgti.co.uk/forum/index.php/topic,24226.0.html which seems to say the workshop manual says they SHOULD replace the bolts...

Your right I was just quoting other people.

Lol, i'd just dug out the link to that image on my PB account but you already found it yourself.  I posted that last time we had this debate.

OP - If your invoice does not include a charge for the new bolts then I think they are bang to rights.

I think I will place an order before I fit my THS!

Just says "repair kit 06F198119A" which I read on another thread doesn't include bolts (pic below).

If they say "you don't need new bolts", how can I definitely prove that they SHOULD have used them, and therefore have them "bang to rights" as you say?

Many thanks for everyone's help.

You could call VW UK and ask them to clarify.

You can also buy the specific part of the repair manual from here - https://erwin.volkswagen.de/erwin/showHome.do

This would likely be the manual you need - https://erwin.volkswagen.de/erwin/showArticleProperties.do?articleId=58906

The bolts that hold the engine mount on are stretch bolts.  So are designed for one use only.  They will fail if re-used, and cause damage.  I hope they have not caused damage to the head/block due to being loose.

Not sure about that.

Quote: Just to let everyone know that I have never had an issue with re using any of those bolts.  Not even VW bother with new ones.

I am not an expert but others are.

Not trying to disagree or annoy just what I have read

Sounds like some spanner monkey has gone for a coffee break whilst doing the O.P's car

Those are big bolts to called "stretch"bolts

they are stretch bolts, designed for one shot only.

QD .. You don't even know whether the VW tech tightened them in the 1st place, so whether they were reused would mean they have indeed sheared off, or were just sat in the castings on the Engine mount ..

Only the O.P and tech at vw will see whats happened... i still think they wernt tighten and forgot about personally. But like you , only asuming as to whats happened...

They are a fair size bolt, they wont break under such a small ammount of torque. Its more like "good practice" to replace them.

Always makes you wonder why wheel bolts aernt replaced everytime a wheel or tyre is changed?

New bolts may well have Loctight on the threads to prevent them from rattling free, rather then a bolt breaking..

I give up.
