Hi.

I was recovered to a dealership 3 weeks ago after going into limp mode EPC and getting an Oil pressure sensor failure warning.

A blade type fuse was replaced and car returned to me.

After 3 weeks and 1000 miles i had identical issue and car had to be recovered again.

Prior to all of this the engine had suddenly developed a very noticable clatter - initially under load but after the first sensor issue its present all the time. Skoda wont look into this unless i pay £1500 for strip down only.

I have All in cover btw.

Here are the codes the Aa downloaded.

What would cause repeated sensor failure?

Is the clatter caused by lack of oil circulation given the failue? - both times the failures occurred was at mway speeds on 100 mile journeys.

Car is 2019 1.5 tsi 2wd.

62k.

Full dealer services.

Oil level correct.

Hi - I picked my car up today after being at a Skoda dealership for repair.

They ran a sequence of 18 Skoda UK recommended tests to check the wiring etc - all of which resulted in reporting a failure in the fuse (SB4). ((AGAIN))

The dealership replaced the fuse and as this has appeared to clear the faults and the car runs ok they have returned the car to me asking me to drive for another 2000 miles to see if the fault re-occurs at which point 'further Skoda recommended tests' could be offered. The hope is to see if further sustained long distance mileage is somehow causing the error.

Guess what?....

I got 6.1 miles and it has failed again!! - car in limp mode but it is totally undriveable - it cuts out and has a really lumpy engine when it does run..

Recovery to dealership in the morning.

Does anyone have any suggestions as to the cause please as its clearly a weird one

I'm no expert, but looking at the data on the AA scan tool there appears to be quite a few 'short to ground / earth warnings. I would be looking for possible damage to a wiring harness.

This what the dealership have been doing for the last 2 weeks. They say they cannot find a fault. They say the fuse is responsible for those systems so when the fuse goes it reports as O/circuit.

Replacing the fuse resolves the error codes.

This might help.

Thats a lot of short circuits etc. Might be worth checking if the oil pressure regulator shares an earth with any or all of the others.
