Hi I was driving the yesterday and I heard a knock. the car started having a weird vibration noise though the car like the exhaust was touching the body. Got told it might be the engine mount. Shore enough it was. It is the one near the cam belt and on bolt has sheared off and the other one looks like it has an extra nut in place acting like a washer between the mount and the bolt head. Is this normal.

I had the cam belt last may and I heard that the garages remove the mount to do cam belt should. I go back to them and asked them to sort it or am I better off biting the bullet an just go some where else.

I have over last could of mouths had a mis fire on cylinder 3 the 3&2 so changed coil packs and still getting the faults and also getting mis fire on all four cylinders any ideas?

Many thanks taking your time to read this and your help/advise would be a great help.

That engine mount does have to be removed when changing the cambelt so I'd go straight back to the place and tell them they need to fix it.

Engine mounts do not fall apart like that unless they have been mishandled, and if they try to say the damage was there when they got it, then you fire back that they didn't tell you about it, which makes it hard to believe them. Mind you, it is a fair while since the job was done so they may say it wasn't like that when they had it...

I'm guessing, but maybe the extra nut was because the thread had stripped lower down and this was a bodge to reuse the bolt, using the lower threads that had not been stripped. Shockingly bad practice, and bound to fail. Does not fill you with confidence to keep on using them, does it.

Are they stretch bolts that shouldn't be reused? That would make them snap.

Now that second bolt, the one with a nut underneath the head, doesn't look like an OEM bolt at all. I wonder if they snapped a bolt, replaced it with a gash one that was too long and used the nut as a spacer? Putting a spacer like that in will mean that they could not set the torque correctly: fixing torque is mostly set by friction between the contact faces of the fastener and workpiece, and someone has put a great big washer in there...

I can't quite tell from the pic, but I assume that second bolt is loose?

I've done a bit of research and the Seat workshop instructions for the engine mountings say they should use new bolts and not reuse the old ones. They are stretch bolts, it seems.

Here's an old thread about the very same problem.

Bolts should be available from a dealer, or you could try Sere motors, one of the forum sponsors. You should not need a new mount, unless it has been damaged by the clumsy bodgers.

Thank you. I tried to do up the bolt that looks loose an seems like the thread has gone can you get a new bracket? That connects to the engine?

And can anyone tell me what type of bolt the ones are in the picture as having problems with that dealer not really understanding the bits I need.

If this is the same dealer that caused the problem in the first place, they need shooting. And certainly reporting to Seat UK.

Using VAGcat, a web-based copy of the parts catalog (the dealer should have access to a fully up-to-date version from VAG) and asuming you are talking about the LCR you show in your profile, the parts you need are as follows.


Support bracket / AGN,AGR,ALH, AHF,APG,ASV, AUQ,ARY,AMK, BAM automatic: AEH
(attaches to engine on cambelt side, mount bolts screw into this from above - this is the one you think you might have stripped threads in)

Engine mount - to - support bracket bolts
hexagon head bolt c/w shoulder M12X1,5X65

Support bracket - to - engine bolts
Front / AEH,AKL,AGN, AHF,AGR,ALH, APG,ASV,AQM, ARL,AUQ,ARY, AMK,BAM

N 90712401

Rear (longer) / AHW,AEH,AKL, AGN,AGR,ALH, AHF,ASV,APG, AQM,AXP,BCA, AUQ,ARY,ARL
hexagonal head bolt BM10X112
N 10209801

Engine mount right / 6 speed man. gearbox: AUQ,ARY,AMK, BAM
(I don't think you will need to replace this)

Thank you no I had a bad experience with seat in Swindon so thought I would try another garage which I was told was good so trusted them to do the cam belt first problem I had was the engine seemed flat to which I found out they didn't do up the top jubilee cilp on the pipe to the turbo for the intercooler and they said it wasn't them it was all fine when it left and now this so no change of them owning up to this and no I will not use them again but still looking for a garage that I can use and trust around Swindon.
