Vauxhall vivaro and movano knocking or banging noise on front.

I have recently experienced on the vauxhall vivaro and movano on two occasions these models have had a really bad knocking or banging noise. After initial inspection nothing has been found.

 Firstly, It’s worth noting at this point that these models are prone to the front top suspension mounting collapsing. This can be simply be diagnosed by looking at the top mount under the bonnet. If faulty the will be a significant gap and it will also be slightly offset. Not central. After inspection this is what happens to the top mounts.


Secondly, If this is not the cause of the noise and after frustration trying to find find the noise it is worth checking and tightening all the subframe bolts and wishbone bolts. These may appear tight and show no signs of wear. Once completed road test and listen. Hopefully now the knocking will have gone.

    Top mount, bearing causing knocking,
    but also check, sub frame mount, ball joint bolts then the usual suspects, drop link, actual ball joint and a new one to me the anti roll bar rubbers.

This is a oil pressure fault   The problem.  This engine although a good engine with some fantastic technology built in has a timing belt that is inside the engine.  This may have seemed a good idea to the designers but it deteriorates in the engine oil, flaking off and clogs and blocking the oil pick up. If left could end up in major engine failure.  The solution.  Quite simple really, remove sump (easy task) check and clean oil pick up. Then change cambelt. Quite a Job.  If you want to see how to diagnose and solve this on your psa 1.2 Puretech Engine i have made
