Its exactly 1.7. As per ElsaWin. If you put in 1L, you probably damaged the unit.

Open it up, itll be rusty and need a clean. Mine worked fine after this.

Ok so I pulled it apart, no PCB anywhere. Turned out to be rusted parts seized. Cleaned them up, lubricated and now its working fine. No need for parts. Simple job. Remove wiper, 10 mm nut, remove trim (clips and 1 Philips head screw for handle, remove 3 x 14 mm nuts, wiring connector and fluid hose. Pump is free, then remove torx screws to remove plastic cover, clean and reassemble.

Just did the same. No movement whatsoever. Opened it up and there it was rusted tight. Cleaned it up with alcohol, deoxit and WD40. I think the order of failure is, blocked jets result in back pressure of water into the housing causing rust, causing it to mechanically seize. The motor was fine, just the moving parts that refused to move. At least that was on mine. Different unit, but very similar and the same looking issue.

Totally understand. Its about an hour to two hour job, so don't pay too much for labour. The pump is cheap too, probably no more than 50 quid.

vacuum leak

inspect the oil when you change it for sludge. if it is present, change the oil and filter every 1K miles for a couple of times. If its clean, dont stress and continue every 5K changes

dont stress unless you have reason to. the sump is easy, but if youre not getting issues, just do normal maintenance.

drop the sump pan and inspect how bad the build up is. unless youve kept up with oil changes you can make things worse with a flush.

Read the TSBs, they go into further details regarding blocked valves etc

my guess is carbon build up

could be anything from an exhaust leak to a waste gate. can you be more specific or record the noise?
