I had an Island Green 1.4tdi, barely run in at 210,000 miles, 60mpg, sailed through MoT! All standard so don't fix which isn't broken.

A fuel pump leak & lack of spares meant it had to go to WOMAUTOMOTIVE in Stoke-on-Trent who had a selection of donor cars. Our "Dinky Toy" is now back on the road with a new owner. My good lady wishes we still had the A2.

Electric fuel pump - not filter 🫣

I bought a 2nd hand A1 TDI from a garage in Plymouth. It too had the same high pitched squeal which sounded louder from the rear right of the car, both inside and outside.

We took our car to a local, trusted workshop for a service & they identified the engine bay fuel filter canister had never been replaced in its 75k history, despite the service history showing complete. A new filter was fitted and 10k later the car continues to run smoothly and quietly.

Hello all.

Just bought a 75k miles 2018 1.6TDI which also makes an intermittent high pitched squeal from the right / rear side of the car. Turning the engine off & restarting sometimes stops the noise. Car is going back to the garage where we bought it from & I will update you on outcome. Not holding my breath as they sold the car with 1 winter tyre (FOS) 1 part worn (FNS) & 2 cheapo-no-grip on the rear!
