If you use it, replace it.
Sounds as though you do not want to waste money on something you do not use.
Are you from Yorkshire or Scotland.

Sounds like a rubbish towbar. Bike rack and bikes and it bends, caravan fully loaded and it overtakes you down the motorway. Take it back and get a refund. Not fit for the purpose etc. The small weight you are carrying should have no effect on any towbar. A major redesign is in order or decent const...

Hold up button and give it a wee push to help it.
We all need a helping hand sometime.
Level ground is a must for mine or it gets stuck, just like yours.

Good to see that refunds are now given when it does not work.

Seems to be a problem after 3000 revs and no power and engine starts to give trouble. When does the turbo kick in and is it working. Could be a simple turbo clean adjust etc. Filter tight was just a filtration problem, alternative fuel is thicker and some filters stop it getting through. Decent gara...

Looks like tracking is out.
Check track rod ends, wheel bearing play and steering rack security.
Wheel nuts as well.
Took 2000 miles to get there and no other problems, tracking is first choice.

WHat is coming out of the exhaust when it struggles. Did you do anything to the bongo just before problem. Proper fuel filter replacement, too tight for non pure diesel. As said before, run on pure diesel to see if fuel is problem. Pipe from tank to filter cut squashed etc. Pipe at filter have washe...

Try exhausting the brake servo and see if this also lets the brakes release.
Just press the brake pedal a few times until it is empty, engine off.
This assumes that a bongo runs a normal servo.

Those bloody jocks are always causing problems.

What condition was the cambelt.
If the camshaft is pinched by the out of alignment bearing carriers, the cambelt would have to work harder to drag the shaft around. Did the belt fail/slip and cause valve/piston collision and then the camshaft snapped.

Fit a new set, problem solved.
As you say, they wear out.

Plugs get slow to heat and also dont get up to full temp.
Get a new set.

Check wires at horn for 12v using a multimeter.
If 12v are there, new horn needed.
Easiest place to start.
Or fuse first

When door is open, if you give it a little push in at the back and it slides easier, the "hinge" is needing a little lube. This is the one in the middle rear and it holds the runner. This was causing my door to stick.
