Are you using a pc or Apple? Apple adds on files which have to be deleted. There is a thread somewhere on this forum explaining this.

Care to share?

As I read it, the OP did not fill it up to the top. The level rose from the minimum level to the top as he was unscrewing the cap.

If you're replacing them yourself, there is no labour cost involved. If you get a garage to do it, then you're going to be hit with a labour charge every time, so it would be cheaper to replace all four at the same time.

It's a TDI

Was it ok before the cambelt change?

Wrong forum

Ask your boss if any mods have been done

This one comes with the sensor, but no cap. https://www.autodoc.co.uk/ridex/14738702#coolant-expansion-tank

If the engine management light is on, it will fail. A warning light only will probably be ok. Call the mot garage and ask them.

Which system in the car do you have?

Ignition on only, no need to have the engine running.

1.6 TDI here. Gets up to 90c on the gauge no matter what the outside temp is. What the actual temp is I've no idea as I don't have OBD11 monitoring it.

Try getting the fault codes read first.

That would seem to rule out anything related to the engine then. Can you post a video or audio file of the noise?

Does it do when coasting with the engine off?

It will probably fail the MOT with the light on.

Plenty of info on Youtube.

Manual or auto?

Yes, I should have said flick it down again instead of up.

Finally got a chance to do what you asked. Drove down a steep hill, stopped with full pressure on the brake pedal, stop/start did not work. Into reverse, foot off the brake, after a couple of seconds car reverses on idling speed. I then accelerated a few yards and stopped with full brake pressure, s/s did not work. Did the same thing again, but this time as soon as I selected reverse I went from brake to accelerator and car moved backwards straight away. Again after stopping s/s did not work. On a level road, driving forwards and stopping s/s worked. Reversing and stopping s/s did not work. Hope this is some help to you.

With the selector in D, flicking the selector down will put it into sports mode, flicking it back up will put it back into whatever mode had been selected. For manual shifting, in the D position, move the selector to the left and then flick the selector down to downshift or up to upshift. The middle display on the instrument panel will tell you which gear you're in. Move the selector to the right to go back to auto mode.

This is what I have.
