2009 TDCI  , slow washers  / trickling   / 1 side works other trickles ....

 

here was my Quick fix2 minute fix .. remove the side of Felt / Sound proofing nearest the jets not working , 

( the clips have a push/ pull tag and come out really easy so dont snap off or force - just be gentle and see how they pop off ..

under the deading quilt / felt   , the pipe had simply popped off ( maybe by me  forcing water thru when frozed )

a quick check  ,, Before you try to trace Fault   from fuses , pump , clogged filter etc  -  to see if this is your fault ,   Pop the bonnet  so it faces upwards back tro window screen and press water jet button 

if you see water running out from  under the sound dead felt ,,, thats your cure 😏  ,  now see the super charged jets back to normal lol

Great tip, I always use to pop the bonnet so it faced downward over the front grill
