Reviews of Bosch fuel pressure regulator

With "NO" MIL on, 22 year old Bosch OEM fuel regulator installed, there was poor performance under load and upon hard acceleration. LTFT under hard acceleration went to ~13%. But, LTFT under light soft acceleration went to 4%. After replacing fuel regulator under hard acceleration LTFT 8%.

So I bought an injector machine. Flow tested the injectors found out my 440's were really 380's. Swapped out 3bar for a 4bar fpr. Runs a bit better.

The fuel(diaphragm) pressure regulator failed and caused a fuel leak into the air box. The car had a hard warm start issue which led me to inspect the regulator. After not being able to start the engine while warm, I pulled the vacuum line from the regulator to discover fuel dripping out of the rear. After installation of the new regulator and air filter I checked for leaks and drove home. Once I arrived home I popped the hood and checked for leaks and any smell of fuel. All is well!

The g60 oem fpr part # is 535 635 735 5. The same part without the VW part # made by Bosch is 0 280 160 235.

Replaced the leaky fuel pressure regulator with a new original Bosch FPR and the car runs fine again. Solved two issues, one is the rough idle and stalling.

I put in the Bosch 0280160235 and it worked fine or at least I haven't noticed any issues. Fit was perfect. The new FPR solved the idle and stalling problem

I installed new BOSCH FPR yesterday and it did not change a thing) Plus I don't have any lean or rich codes and the car misfires even at lambda 1(14.7 AFR)...

I'm a bit disappointed with China and Taiwan parts too I ordered a fuel pressure regulator from GAP said OEM Bosch which would lead me to think ..... ok German goodness:thumbdown: nope, says made in China right on the top hat of the regulator
