Hi all,

Got an issue with my 2010 Skoda Superb 1.8 TSI (CDAB) and hoping someone might've had a similar issue or can offer some guidance.

Started with a low oil warning a few weeks back – not ideal, but I topped it up and thought that’d be the end of it. But since then, whenever I put my foot down and it hits around 4000 RPM, the engine just falls flat on its face. Feels like all power is suddenly cut – it simply won’t pull. It doesn’t stall, just goes completely gutless. It’s consistent and repeatable under load. Only way I can deal with it is take the foot off the power, keep it under 4000 RPM and slowly build speed.

After a couple of short test runs, the check engine light came on. Plugged in the scanner and pulled code:
P2293 – Fuel Pressure Regulator 2 Performance.

From what I can tell, that usually points to the high-pressure fuel pump struggling under load, likely not delivering enough pressure at the top end. No misfires or other codes, just that one. Feels like it’s fuel-starved, but only at higher revs.

So far I've:

• Topped up oil (was a bit low, not dangerously).

• Monitored with a basic OBD reader.

• Checked for obvious fuel leaks – nothing visible.

• Read some forum threads on HPFP failure symptoms – sounds like a match.

Other issues worth mentioning:

• There’s a bit of an oil leak around the engine – not pouring out but definitely losing oil. (I can't quantify how much, but it needs topped up fairly regularly. Hoping the garage can trace it.

• Something is rattling underneath – sounds like a loose heat shield or bracket. (I'm sure that is coincidental as it predates the issue)

• The car was recently serviced, including an automatic gearbox fluid change, so this isn’t a long-neglected motor.

At this point, I’ve booked it into the garage, expecting they’ll confirm it’s the HPFP.

Has anyone else had this specific issue? Is it usually the HPFP or could it be a sensor/fuel filter/regulator? Trying to avoid throwing parts at it if it turns out to be something daft.

Cheers,

Right, so the garage determined a replacement high pressure fuel pump was the answer. So they ordered and fit it. No change.

Has anyone else had this issue?

The car is a 2010, so I'm loath to throw too much money at this because I've been burned by my last diesel Skoda, which was a write-off due to electrical issues.

So the garage said;

"guy next door Skoda Vw garage said he spent over 700 trying to fix one the same as yours said it’s not practical to through money at it he did pumps etc still not going he traded his sons in"

And so I'm picking the car up soon. I suppose I'll need to take it to the dealership, but I have no idea how much this will cost.

Put it into the dealership today, hoping for a positive outcome.

Quick update on where I’m at with this saga.

Car’s been with the Skoda dealership for a while now (Since Wednesday last week). I spoke directly with the Master Tech today. His current view is that the high-pressure fuel pump (HPFP) is still the most likely culprit. Interestingly, the third-party company that tested the injectors have also suggested the pump as the likely source of the issue.

Injectors have been tested – three came back fine, with injector 4 showing an uneven spray pattern. They’re being professionally cleaned rather than replaced at this stage.

The compression test passed and so that's not the issue.

The tech has also inspected the HPFP actuator rod/follower, but can’t see the full length of it without removing the rocker cover. He’s reluctant to do that right now as it would mean yet more labour cost. His view is to try the HPFP first, then reassess if the issue persists.

So at this stage, the plan is:

• Fit new HPFP (third-party part, OEM is on backorder).

• Refit cleaned injectors.

• Reassemble and test.

Still no guarantees this will cure it, but that’s the current working diagnosis. I’ll update once it’s built back up and running again.

Has anyone else had experience of P2293 being stubborn like this? Did the HPFP fix it for you, or did it turn out to be the actuator rod/cam follower instead?

Do you know that original injectors only cost 54 euro? https://www.motointegrator.nl/producten/1273239-brandstofinjector-bosch-0-261-500-160

How much did the testing and the new one cost?

Regarding the high pressure fuel pump: The ones from 2010 and 2011 (and maybe later) were prone to fail. Mine (from 2011) failed in 2017 after only 5.5 years and 75.000 km.

I now have an upgraded version.

Don't know anymore what fault code I had. I do know that I had severe loss of power, since the pump was doing totally nothing anymore. The fuel pressure at the injectors was just the fuel pressure from the pump in the tank (around 4 bar?). I found it a miracle that the car actually ran on such low fuel pressure, and that I could drive it to the garage.

If yours was still the original pump, it's logical that the garage suspects it.

Good news at last – the replacement high-pressure fuel pump (HPFP) has resolved the issue. The car now pulls cleanly past 3k RPM without the sudden power loss I was getting before.

The injectors were professionally cleaned at the same time, which should help with the carbon build-up problem and hopefully stop the recurring spark plug and coil failures I’ve had in the past.

So for anyone else chasing a P2293 on a 1.8 TSI, even though there are multiple possible causes, in my case it was ultimately the HPFP. Cleaning the injectors was worthwhile preventative work too.

I had no idea about the fuel pump issue! The Skoda Master Tech was acting like he'd never seen anything like this before and buggered around with it in the shop for over a week.

The third party bench testing for the injectors, and the HPFP cost £80 +VAT.

They quoted me like £250 + VAT for the injectors which I didn't fancy.

Thanks for the tip, though. Very insightful! I wished I had known that earlier, I'd have pushed for them to just replace it.

I found the thread (from 2017) in which I described my error and its fix. (Use Chrome to translate if you don't understand Dutch.)

My error was apparently P0087.

Back then the fuel pump was revised quite a few times to solve its problems.

Was the £250 + VAT for the injectors for four of them (sounds like a reasonable price), of per piece? (which is a quite steep...)
